Twelve kinds of paper packaging printing process, how much do you know?

Finishing process paper packaging products are processed fingerprints of its completion. Surface processing in order to enhance the appearance and quality of packaging, mainly film, process are uneven stamping, die-indentation and other processes.

    First, the film

    Film is a transparent plastic film is adhered to the printed surface of the cover by pressing more smooth and shining, graphic color more vivid, but also play a waterproof, stain resistant, can be divided into two surface machining and forming stamping, polishing wax and other processing; forming seed processing technology. Even coated print surface abrasion, folding, resistance to chemical corrosion. However, due to non-degradable plastic film, recycling is difficult, easy to cause pollution. Therefore, in the case of glazing should be used with caution can replace plastic coating process.

    Second, stamping

    Also known as hot stamping printing, is the need stamping patterns or text made convex version, and the help of a certain pressure and temperature, all kinds of aluminum foil printed onto the substrate, showing a strong metal light make products with high-grade texture. And because aluminum has excellent physical and chemical properties, may play a protective role in print. Thus stamping process in modern packaging and printing is widely used.

    Third, polishing wax

    On just painted or sprayed with a colorless, transparent coating on the printed surface, brush goods luster, and surface water played a role in anti-oil packaging. Product shine bright, and play a good barrier effect. So as to form a layer of glossy film, in order to increase the print wax melt wax is applied on the wrapping paper.

    Fourth, uneven imprint

    Bump on the printed surface of the platen is a special technique of decorative processing. It is the use of convex mold, at a certain pressure, so that the print substrate plastic deformation, and then to the printed surface of the artistic process. Embossed graphics and a variety of convex pattern shows different shades of patterns, with a clear sense of relief, increasing the printing of three-dimensional and artistic appeal.

    Five die-indentation

    Also known as pressure die-indentation cut type, buckle knives. Carton packaging and printing needs when cut into a certain shape, can be accomplished by cutting indentation process. Die steel blade is arranged in the mold (or with steel carved into the mold), box, etc., in the cutting machine cut into a certain shape of the sheet rolling process, hollow in the middle part of the principal display panel technology is the use of die-income, become the entire package of personalized decoration. Indentation is the use of steel wire, pushed out by stamping or leave marks on paper for bending groove marks.

    Sixth, bronzing

    Gold, silver, laser gold, bronze gold and other, generally only after a plastic gold foil or silver; a film to have a pair of bit lines; bronzing diverse, but also according to the substrate stamping classification, gold foil paper, hot velvet hot plastic and the like.

    Seven local UV technology

    A silk screen process, performed by local graphic carton surface coating UV varnish to enhance the effect of Indian goods bright.

    Eight, freezing snow

    Freezing snow effect is screen printing ink on paper Gold, silver cardboard, laser cardboard, PVC and other substrates by UV irradiation and UV light cured wrinkle in printing surface of fine sand having flu, feeling delicate effect. Because it exhibits such as a thin snow or ice-like effect in printing surface, commonly known as the industry's "Snow" (large pattern) or "freezing" (small pattern). This process has a pattern of fine, stereoscopic, luxurious and elegant characteristics have been widely used in alcoholic drinks and tobacco boxes, calendars, gift box or other printed materials are visually attractive.

    Nine, reverse scrub

    Reverse grinding process is a new printing process that appears nearly two years, it needs several special base oil or varnish process to complete; it was also called reverse coating process, it would be seen as a partial A new technology of light. The process is in accordance with the normal printing color order printing, the ink is dried or cured completely based on the use of offset connection (or offline) mode on the local area and India do not need to highlight high brightness level of special base oil, base oil to be completely dry before the full version of the way on the entire printed surface is coated with UV varnish. Ink film happened in the region in the polymerization UV coatings and base oil contact form small particulate form matte or frosted matte; in the bottoms of the unprinted region forming high-gloss UV coating mirror. Eventually, the printing surface to form a local high gloss and low gloss matte local area. Two completely different gloss to achieve the effect of a partial image of high contrast, and highlight the graphic embellishment glossy mirror.

    Ten, embossed gold foil

    This process is changed by tipping version show a sense of three-dimensional metal stamping stronger way. Changes by uneven relief pattern, so that graphic showing a metal relief-like texture, so out of gilt graphic plane, bringing a stronger visual impact.

    XI, laser transfer

    Have eye-catching visual effects, can be very effective to improve the packaging grades, the process can be on the surface of a smooth plain paper, printing full version or partial transparent laser effects, and change the past but to use laser printing paper, or paper surface of the composite proprietary laser film in order to demonstrate the effect of laser processing methods, can do flexible laser pattern.

    Twelve, lithography paper

    One technique paper material content is very high, the integration of local embossed holographic laser anti-counterfeiting, vacuum aluminum, paper and plastic composite cutting, cover many advanced digital printing technology, has changed the past situation of a single laser pattern effect, eye-catching paper unique visual effects, coupled with a unique anti-counterfeiting features, not only can not be copied plagiarism, but also for consumers to visually identify the authenticity.
