Three categories of environmental plastic packaging

If you press the raw materials that so environmentally friendly plastic bags mainly into three categories: recycled plastics, biodegradable plastics and edible plastic.

First, the recycled plastic

Recycled plastic is reused plastic, after grinding operation by mechanical blade, thereby completing the re-use of plastics.

Recycled plastic refers to the processing of waste plastics by pretreatment, melt granulation, modified, and other physical or chemical means re-obtain plastic raw materials, plastic is reused.

Plastics recycling biggest advantage is the price is cheaper than the new material, although it is the performance of the property as a whole are not as strong new material, but we did not need to use the kind of performance in all aspects of property and many products are good material productions to make it, so no need to waste a lot of attributes, and recycled materials will be different, depending on the needs, only one aspect of the process attribute, it is possible to create a corresponding product can be, so do not let the loss of resources .

Second, biodegradable plastics

Biodegradable plastics is the added amount of the additive in the production process (such as starch, modified starch or other cellulosic, photosensitizers, biodegradation and the like), decreased stability, easier in the natural environment biodegradable plastic. Biodegradable plastic is divided into four categories:

1, biodegradable plastics

Holding dry, without dark, wide range of applications, not only it can be used for agricultural film, bags, and is widely used in the field of medicine. With the development of modern biotechnology, bio-degradable plastics more and more attention, it has become a hot research and development of a new generation.

2, the light-degradable plastics

Photosensitizer incorporated in the plastic, the plastic in the sunshine gradually decompose. It belongs to an earlier generation of degradable plastics, the drawback is the time due to sunlight degradation and climate change are difficult to predict, and therefore can not control the degradation time.

3, water degradable plastics

Add water-absorbing material in the plastic, disposable after use in water that can dissolve away, mainly for medical and health aspects appliances (such as medical gloves), to facilitate destruction and disinfection.

4, light / biodegradable plastics

The combination of light and microbial degradation of a type of plastic, it also has the characteristics of light and microbial degradation of plastics.

Third, edible plastic

Edible plastic, is an edible packaging, ie, edible packaging, generally composed of starch, protein, polysaccharide, fat, complex class composition of matter, is widely used as plastic wrap, packaging films, high packaging, food packaging, Pastry packaging, flavoring and packaging.

With the development of modern food industry, food packaging constantly updated, one can improve the contradiction between environmental protection, new packaging materials and food packaging technology materials - edible packaging stand out. Edible packaging material means that after the realization of the function when the packaging, the material can be transformed into an animal or human edible raw materials, packaging materials can be achieved is a function of the transformation of special packaging materials. Edible packaging material is a waste-free packaging, is a resource-based environmentally friendly packaging materials.

Flexible packaging market welcomed by four important factors

1, transport facilitation: flexible is lightweight, making it both at home and overseas markets in the distribution process is more economical. For expensive and compact product is the most suitable.

2, reduce waste: flexible plastic material used in a lot less than the rigid container packaging, this method reduces the unnecessary waste, is an economical choice.

More importantly, the new methods and techniques to broaden the choice of people in the life of flexible packaging. For example, experts have found a way to promote the decomposition of flexible plastic. In landfills, an additive is added to the packaging material, in 18 months of microorganisms inside the package will be changed. Packing after being decomposed into water and carbon, their impact on the environment is less than traditional rigid packaging.

3 and attractive: flexible packaging more attractive to consumers, because it has a strong appeal on the shelf, often played a compelling billboard effect. For example, a stand-up pouch would be immediately subject to the concerns of consumers.

4, protection products: flexible packaging material can usually be used to block harmful ultraviolet rays, water, grease, pollution and oxygen emitted by the sun.

Aluminum foil has a particularly high oxygen transmission rate (OTR) and water vapor transmission rate (MVTR), the need to resist the harmful elements provide functional products more powerful package.

Food Packaging Evolution

Food packaging is a topic of ancient and modern, both ancient agrarian age, or science developed today, are the people throughout the research and exploration of the topic.

   As early as in ancient times, humans began to explore food packaging. Ancient human to make long-term storage or portable food, they put leaves or vines loaded food prepared in blue, or mount bamboo tube.

   Around 1000 BC, the Greeks with cask as food containers and packaging, and outputs the country, at a time when consumers use packaging made from sheep or pigskin placing food to carry.

   As early as 3,000 years ago in ancient China, people have started using ceramics as canned food containers to be enclosed. Which are described in detail in "Arts for the People", "the great cause of Supplements" and other books.

   Food packaging in the true sense, canned food stored from the beginning, which originated in the early 19th century. 1804, French Appert successfully use glass bottles to save food, since the emergence of the use of glass as a food packaging cork.

   1810, British Durand made successful use of food packaging made of tinplate, the so-called tin cans. Thereafter, more and more metallic material is used for the manufacture of food packaging.

   Early 20th century, all kinds of plastic, paper composite cans into production, so that food packaging containers made of rigid canister to extend soft cans, containers varieties more innovative, diverse and practical.

   Around 1960, Taiwan imported plastic films for food packaging, from the early single MSG bags to today combine plastic film, metal foil, paper and other permutations and combinations of high-performance multi-layer flexible packaging materials, has become a mainstream food packaging.

   In recent years, high barrier film material because of its barrier properties, light weight and other characteristics become an important trend in the development of food flexible packaging materials, EHA Xiamen long plastic barrier film developed, with its excellent barrier properties, high-temperature cooking, as well as the case of the same barrier properties thinner, become an excellent representative of this trend.

The new color packaging bottle design

Today buy things at the same time, in addition to focus on product quality, it also increasingly valued commodity in the fine aspects of packaging, the bottle, how do attract the eyes of consumers, but also from the four new elements to the overall innovative design concept . Bottle design of four new elements:

Duplex extending tag if your product is transparent liquid, packed in a transparent bottle, then there is a way to give you more space for packaging design, and low cost.

The characteristics of the customer base design packaging Unilever AXE series of packaging products have a very clear position - the age of young people 18 to 35 years old between. So they focused on packaging design to attract these people. This series of bottles is thick molded black plastic container, rough appearance, very popular with these young people.

Design of small reusable drinks packaging market has matured, competition is fierce. If you think that there have been no novelty act, you may be wrong. Abroad, a tea company has launched a special packaging. It launched the product itself is very special - Add pomegranate juice tea. Packing even more noteworthy. Drinks are mounted in a common elongated glass bottles, the above is the cover and heat shrink labels, the label reads: Remove the label, leaving the bottle.

The packaging design is not just a fun packed children's patents, adults like interesting things. Follow the market trend, the adoption of new packaging design sophistication of the place, combined with a stylish minimalist design, in order to make the market more diversified bottles.

Five factors driving the development of China's market of flexible packaging

For decades, China's packaging industry output value of more than quadrupled, increased from 2002 to more than 2500 yuan to 2013 of more than 14,000 yuan, after the United States became the world's second largest packaging country. Packaging industry maintained a momentum of stable development, has opened up a new situation in innovative adjustment. Recently, the global market research firm Smithers Piper Solutia Inc. recently released a survey report on the flexible packaging market in 2015 made a forecast of the five driving force.

Flexible packaging is an important part of the packaging industry, but also shoulder the task of technological innovation. Flexible packaging industry currently remains one of the fastest growing fields. According to Smithers Piper Connaught's latest statistics it shows that the consumption of flexible packaging global market rate of 3.5% per year to maintain growth over the next five years, and will reach $ 231 billion in 2018 (203.7 billion euros ʱ?? Technological innovation is the core areas to maintain high growth momentum.

Although flexible without their own shape, but with the continuous expansion of its range of applications, it has become a member of the family package, and in fact, its shape can change with product and change.

Expand the range of applications of flexible packaging is driven by the five main factors, these five factors also determine the future of flexible packaging in multiple markets growth. They are: bio-packaging, barrier films, bags, printing and design and intelligent packaging.

Biological packaging

In recent years, degradable plastics, research and development of biological materials, greatly promoted the development of the global packaging industry, has become quite popular packers choice. However, the speed of degradation in the soil of its existence slowly degradable plastics can not be recycled in a timely manner; can not be completely degraded, there will be stains on visual applications such drawbacks, its application prospects appeared limitations. Thus, the natural biological packing material with complete environmental advantages, the packaging material of choice for the future.

In the food industry, packaging bags is perhaps the greatest source of pollution. With the advancement of people's awareness of environmental protection, as well as science and technology, natural biological packing material with a completely environmentally friendly advantages, it has become one of the most developed packaging materials present potential. Future, natural biological packaging materials will continue to support improvement and innovation in science and technology, the immature gradually improve, or will occupy a considerable market share in the packaging industry.

Barrier films

All along, food safety is a common topic of concern to people, and to ensure the quality of food in terms of packaging materials play an extremely important role. For example, the use of high barrier films for food packaging, extend frozen food, such as meat, cheese, fish and milk and nuts and other non-frozen food shelf life.

According to market research report high barrier film industry, the global high barrier packaging film market is growing rapidly, in 2014 sales of about 1.76 million tons, with sales of $ 15.9 billion. The next 5 years, the global high barrier packaging film market will continue to maintain steady growth, the average annual compound growth rate will remain at 5.0%, 2019 sales expected to reach 2.24 million tons, sales of more than 20 billion US dollars.

High barrier packaging films mainly used in flexible packaging six major categories: plastic bags, stand-up pouches (including cooking and non-cooking type), lidding and forming the base, wrap film, blister packaging substrate. Among them, the plastic bag is the most important category, accounting for more than 50% of 2014 global sales of high barrier packaging film; lidding and forming the substrate ranked No. 2. The next 5 years, stand-up pouches will become the fastest growing category, lidding and forming the base of the growth rate will exceed the market average.

Bags

Bags for packaging various articles refers bag for easy transport of goods in the production and distribution process, easy to store. With economic development and people's living standards improve, the demand for commodities is increasing bags, merchandise bags claim to more and more use of the bags value requirements are also increased. The current value of the rapid growth of the packaging industry, highlighting the packaging industry great prospects for development.

China is the world's largest fruit and vegetable production and marketing of a large country, but there are about 30% of the fruit in the storage, transportation and sales process loss, improper packaging which is an important reason, in a highly competitive market conditions, the role of packaging becomes more and more important. As well as to expand the production scale of bags in the market rapidly expanding China and other developing countries, the rising market demand presents complementary trend. The report shows that by 2018, the Asia-Pacific region is expected income is the highest. Among them, food packaging (especially beverage packaging) and pharmaceutical packaging will be the two main growth poles.

Today bags no longer a simple product, businesses and consumers on the quality of bag, material, quality and style are increasing. In North America and Western Europe plastic bag usage is already high, change the product mix will continue to support the continued growth in demand in these regions bags.

Printing and Design

Packaging & Printing are inseparable, between the two are interdependent relationship, a good package in addition to printing also requires careful design, the design is the soul of packaging, packaging design success of a product or not, directly targeted product quality , unique packaging design. Among the package, you can highlight how many brands from the company's products and brand, which is unique from the packaging design. The unique design, you can use a unique color, different from other products with eye-catching colors and products meet; on the packaging of shape, and now many are based on common packaging design packaging design, packaging styles lack of innovation We can not attract consumers.

Packaging designed to look like just the packaging of products, in fact, it also shows the problem of corporate culture, brand image aspects. Packaging of quality in the eyes of consumers, many times, reflects the quality of the product, the packaging also reflects the brand's creative ideas. Product packaging is actually pretty big role, not only to show the brand image or product sales booster. Enterprises should pay attention to product packaging design, to create a company with a culture, in line with the brand image, but with distinct characteristics of the packaging.

Intelligent Packaging

The so-called smart packaging, that is, in the conventional packaging technology, adding more relevant information and can use the advanced smart phones, the Internet, things to be read, so that the package has more information capacity; enable consumers You can learn more information about the product when purchasing through product packaging, so as to achieve the purpose of further facilitate the consumers to buy.

For example, people in the supermarket to buy small packages of food, the front can be displayed on the packaging of food names, the main ingredients, date of manufacture, shelf life, etc. must be public information. But the use of smart packaging, since it is possible to double the capacity to provide information, producers can produce information on the main raw material, food processing information, food use precautions and friendship reminders are stored in an intelligent manner on the packaging or on the Internet and read by smartphones.

Smart packaging is a broad definition, which includes a variety of internal information about this product, more than only on a small package foods for example. Because of smart packaging in the packaging of information capacity is multiplied expansion, the consumer is concerned, to obtain a more transparent product information and increase greater selection of room; the producer is concerned, is undoubtedly smart packaging provides a Consumer high-capacity platform to meet directly. Meanwhile, smart packaging in commodity security technology will also receive a qualitative breakthrough. The rapid development of the Internet of Things and logistics industry, smart packaging will flourish.

to sum up:

Faced with growing competitive pressures, flexible packaging production enterprises must improve technology, processes and designed to ensure that consumers are able to distinguish their products on the shelf. According to Smithers Peale Institute survey, printing and packaging companies need to continue investment in new printing technologies to provide richer colors and excellent after printing process, will better enhance their own competitiveness. In the large market environment, China will continue to enhance and liberate themselves in the printing industry, this road, for the packaging industry has opened wider world.

Plastic food packaging recycling is not difficult

Sometimes, sustainable plastic food bags and environment-friendly packaging materials not relations, but with how we handle the product concerned. For example, the bottled water industry has been a lot of criticism, when people drink water that perfectly clean and sealed, resulting in a lot of unnecessary waste bottle. However, some communities and universities are working hard, through the establishment of refills site, reduce waste of plastic water bottles. People no longer need to buy bottles from the vending machines, you can take the empty bottles, filled with water free. This is a good start, but part of the problem of plastic food bags.

Typically, disposable packaging in retail stores now is the most common. From water bottles to drink to personal care products, cosmetics and cleaning products are disposable packaging, and then it is discarded. We hope that some of the package will be re-used, although we also know that recovery is a challenge for consumers. But repopulate the site if we take this idea and apply it to other liquid products, there will be how kind of consequences?

In the past, beverage companies and other liquid products manufacturers the use of glass packaging, may be re-used in the earliest forms of packaging. The reason is that you have to put your empty milk bottles on the door, the milkman will be recovered tomorrow morning! Glass is very durable, easy to clean, and constantly refilled, and when the time is up, it can be recycled. Repopulate the site without lower prices or lower the quality of liquid products, we can significantly reduce packaging waste, few consumers rarely go to those retail stores to repopulate the site. Bulk purchase is a viable option, it is necessary to limit the package, to provide consumers with greater value.

Barrier plastic food bag recycling is almost non-existent, because consumers need to do is fill a box, and then returned to the box. There are many different types of boxes to choose from, there are some specific waste streams, others do not need to waste classification acceptable. When re-using or filling is not possible, recycling is the best method for processing waste streams.

2017 British plastics industry has developed plastic packaging recovery rate of 57%

British plastics industry launched a plan to require the government to make greater efforts to complete the development of plastic packaging recovery in 2017 to 57% target.

This program, called "Plastic Industry Action Programme" called on all practitioners to make efforts to achieve the goal.

2013, England recovered 787,050 tons of plastic packaging. If the government recognized the 2013 total plastic packaging on the market for 2.49 million tons of this figure, then the recovery of the United Kingdom in 2013 was 32%.

British plastics industry has developed in 2017 57% of plastic packaging recycling targets

If not all, such as central government, local government, the waste management agency, recyclers, supporting the project to force users to fully participate in the producers and processors, implementation, and this goal will be difficult.

British organization WRAP recycling company Valpak and cooperation is estimated to be finished until 2020 to reach over 57% recovery target.

Based on this situation, the Government is currently consulting relevant agencies to study whether it should modify this liability target, reducing to 42% of the original plan, and the timetable for completion of delayed.

Meanwhile, the industry also called on practitioners to take various measures to improve the recovery of plastics, including the removal of the policy threshold set by the government to expand the scope of recyclables species, improve the quality of packaging material recycling plant.

This program is the UK WRAP Association and the "Plastics 2020 organization," the two agencies design is completed. "Plastic 2020 organization" is a special group by the European Plastics Association, the British Association of Plastic and plastic packaging film composed of the Association.

Change a small bag cutting angle, actually can save so much!

With the diversification of flexible packaging technology and market demand, shaped bags appear more and more in our lives. The traditional process for forming shaped bag bag making machine is to use the system out in the preliminary model shaped bags, and then treated with the punch line punched out shape profiled the necessary follow-up and then trimmed to complete the production of shaped bags, required in this manner specifically one person punching and punching a time only a few bags, punching bags for complex shapes greater inefficiency, if larger orders more punch and manpower required to accomplish large quantities, thus wasting a lot of manpower and material resources.

   Shaped bags for many companies already make use of a bag making machine auxiliary equipment - cutting machine, cutting machine make full use of light, electricity, gas and other automation facilities, comes PLC signals well with bag-making machine Online, to achieve synchronization with the bag machine cutting, well shaped bag making to ensure the accuracy of the line without the need for subsequent processing, and the bag edges smooth curves naturally, and can realize automatic crimping and out of the bag, which greatly improved the shaped bag making efficiency, effectively prevent the line blanking human wave tactics.

   Currently, the die-cutting machine flat cutter prone problem is not durable, manufacturers have put forward innovative solutions round roll cutter, cutter up and down to avoid damage to the punching of the cutter, using a round cutter can effectively roll reduce friction between the cutter and the bag, extend cutter life, it is expected to realize a round roll cutter knife completed more than one million bags of punching, knife and reduce the loss of full production, the maximum yield on the energy savings.

   In addition, to avoid the traditional square-shaped angular plastic bags harm the human body, more and more customers require chamfer bags, which many companies use the latter in packaging on bag machine forming line use Notching machine cut corner treatment, although the line can achieve every corner cut dozens punching bags, but inevitably require human and beveling equipment, especially orders for more business, even Cutaway need dozens and dozens of people were cut angle, but this number does not match with the current trend of saving labor costs. Currently, the most automatic bag making machine comes with dual cutter features, in fact, as long as the flexible packaging business increased slightly change the layout a little flash can be implemented on a punching bag machine use pneumatic chamfer machine bags, then take advantage of dual function bag making machine cutter perfect bag Cutaway detail to achieve perfection Cutaway online, without affecting the speed bag, to achieve human, material savings.

Stand-up pouches will be the future stars of plastic packaging

2014, plastic packaging sales in the global food industry, rose 3 per cent to 1.9 trillion, its global sales in 2016 are expected to rise to 2 trillion.

Market research firm Euromonitor International said that in the food industry, stand-up pouches is undoubtedly one of the fastest growing plastic packaging.

Stand-up pouches is still loved by many brands form of packaging. According to Euromonitor International predicts 2014 - 2019 period, stand-up pouches annual sales will increase by 6%.

In 2014, self-released in the bag, the concern include the world's largest breakfast cereal manufacturer Kellogg's businesses in France launched cereals used in packaging, Heinz food company in Germany to launch a ready-meal packaging and Hulk sweet corn packaging.

"From this year's Packaging Research data, the stand-up pouches is one of the success stories," Euromonitor International head of research RosemarieDowney packaging says, "stand-up pouches are sold very well, is a suitable microwaveable packaged solution that can be used packed ready meals, rice, pasta, biscuits, sweets, savory snacks and ice cream, yogurt and baby food for direct consumption of disposable packaging also occupy a certain market share. stand-up pouches very wide range of applications. "

In 2015, China and India accounted for 50 percent growth in food packaging. 2014 Year in Asia-Pacific sales to rise by 5 percent, or 320 billion package.

"China and India are the driving force of the global food packaging industry," Downey adds, "the level of urbanization and increasing disposable income, coupled with the buying habits of the bulk foods to packaged foods, so that those countries, the more demand for plastic packaging be greater. "

Plastic packaging has been widely optimistic prospects

In the world plastics industry, the largest amount of packaging enterprises, usually accounts for 25% of the total amount of plastic -70% to the plastics industry the most developed States, Japan and Germany, for instance, plastic packaging accounts for 27.2% share of the total consumption of plastics , 32.8% and 27.2%, while China accounted for about 25% of plastic packaging plastics consumption ratios.

    Plastic packaging advantages are: light, soft, less waste, small occupied space, low cost and high cost effectiveness, and therefore more competitive than the rigid packaging, the direction of the plastic material development is to improve performance, reduce costs and environmentally friendly .

    With plastic new varieties, new grades development, processing technology and mechanical improvements to enhance the performance of materials and packaging products, can reduce material consumption and costs, but also with people's demands on the environment.

    According to the European Plastics Manufacturers Association study showed that nearly a decade, the average weight of plastics used in packaging fell 28% reduction in the amount of 1.8 million tons per year, saving resources, including plastic packaging film is most effective, accounting for 70% of savings above, the European packaging materials consumption was 66.4 million tons, of which 11.6 million tons of plastic is 17%, accounting for 50% of packaged goods.

    Therefore we can say, especially plastics plastic packaging is the most effective way to reduce packaging weight, reduce the weight even more than the recovery of a large amount of repeat, the rational use of resources, the role of the maximum.

    Germany "plastic" magazine in the importance of the plastic flexible packaging in food packaging it comes to point out that it has become part of the culture, in addition to the packaging effect, it can prevent damage to the packaging, reduce storage requirements, to consumers provide information more effectively to customer service, so that goods easy home management, and easy to store and transport. This can be represented by the following figures: in developing countries 30% -50% of food in storage and transport damage, while Western European countries currently only 1% -2% of plastic packaging plastic packaging market due to its good overall performance. and low cost, making it one of the fastest growing varieties of packaging.

    It can be seen, the average annual growth rate of plastic packaging consumption in the past and end to all higher than other packaging methods, not only to increase faster than the paper packaging, but also higher than the hard plastic packaging. US data name of the business communications firm plastic packaging industry special report on changing the public provided: total amount of the world's plastic packaging market in 2001 only amounted to 6.31 million tons, the largest amount of food packaging, to 1.68 million tons.

    In short, colorful plastic flexible packaging for its excellent overall performance, continue to replace other packaging, increasing use, reasonable price and benefit the environment and become the fastest-growing products packaging industry, the next few years will continue to maintain good growth.

    To enhance market competitiveness, it will be thin-walled plastic flexible packaging, high-performance direction, multilayer composite membrane demand is growing faster than ordinary single-layer film. The development of new grades and plastics processing technology progress and development of plastic flexible technological progress. Polyethylene films and biaxially oriented polypropylene film applications in coal-ene on the packaging of the most promising.
