UV printing technology for transparent plastic folding box packaging is more popular
Now, daily cosmetics market is very competitive, manufacturers do all we can to find novel and attractive packaging, to highlight the inherent quality of the product and shelf appeal. Retailers shelves display products are so large that forced manufacturers to try to make their products on the packaging looks different. Currently has crystal and transparent packaging materials has become a popular trend, Europe and the United States, Japan and other daily-use cosmetics market generally used transparent packaging, clear and transparent packaging looks more fashionable.
And with the improvement of the UV printing technology and development, the transparent plastic folding box with its expressive commodity, resistance, anti-counterfeiting resistance on the significant advantages gradually popular in the market, has been increasingly used in daily cosmetic packaging. At present, the transparent plastic folding box mainly made by PVC (polyvinyl chloride), PET (polyester) and PP (polypropylene) this three kinds of materials. Comparison is low, because of the price of PVC surface printing performance is better than that of PET and PP material, PVC material folded transparent plastic box is more common. But due to the poor environmental performance of PVC, and industry insiders predict, along with the people environmental protection consciousness enhancement, the amount of PVC will be reduced gradually, and is likely to be replaced by PP and PET. Advantages of the UV printing plastic sheet is heated to softening deformation, folding so transparent plastic box can't hot air drying after printing, and UV curing methods should be adopted, accordingly, printing ink must choose offset printing UV ink or screen printing UV ink, so as to ensure the smooth progress of the printing.

The UV printing plastic box common problems
Compared with the traditional ink printing, UV printing does have a big advantage, but in the surface of the plastic substrates for UV ink printing is still a challenging job. On the plastic substrates for UV printing ink of the biggest problems is how to make UV ink firmly stick on the surface of the plastic substrates, the adhesion problem. UV ink in curing, internal components by crosslinking polymerization, instantaneous changes produce the internal stress of large volume, affect the ink adhesion to substrates. So before printing is typically carried out on the plastic sheet surface treatment, in order to improve the surface tension of the plastic sheet, increase the ink adhesion, the corona treatment to use more. Although the surface treatment of substrates or modification, can improve this problem, but the fundamental solution is to seek and develop good adsorption, shrinkage stress is small, cheap UV ink. Alignment is one of common problems in a UV plastic printing, plastic sheet hardness is larger, softness than paper, easy to produce in the process of printing misregister. , plastic sheet when positioning, can only use push the gauge side, can't use pull gauge side, in order to avoid inadequate power gauge misregister. In addition, the UV lamp in the process of start the heat generated by the infrared ray is enough to make plastic sheet deformation, lead to misregister, print size is not stable.
For this problem, man Roland on the offset printing equipment used eltosch company cold UV technology, the technology in the UV lamp is started by using the reflection of replaceable type to the reflection of infrared radiation, and use the cooling source cooling, reuse of UV light in the process of operation, the UV curing ink. New progress in the UV printing technology launched the latest local UV ink UV - 1278 stereo grating n, mainly used for printing three-dimensional grating diaphragm. Different from the traditional hot pressing molding process, a new process using screen printing method, will ink printing on the transparent membrane, direct forming columnar raster graphics; Stereo grating ink will also be printed directly on the printed matter, form the three-dimensional design, can be selectively make local three-dimensional printing design, print design stereo effect is obvious, and the thermal grating plate, for has opened up a new method for 3 d printing.
With the ink printing grating film can greatly reduce the production cost, improve production efficiency. Printing substrate can be a transparent plastic film, such as PVC, PC, PET, can also be a paper, metal, glass, ceramic, etc., wire mesh of the 200 ~ 350 mesh is preferred. Quickly the colorless transparent ink, uv light curing, curing film not yellowing, good adhesion fastness, good toughness. Used in UV printing speed bully CD74 offset printing machine for the use of a wide variety of substrates commercial printing, packaging and label printing enterprise, as well as the ways to produce CARDS with double-sided printing or book seal products such as printing enterprise, speed bully CD74 double-sided printing machine is an ideal model. In addition to the standard model of the single side printing and double side printing, speed bully CD74 there are all kinds of printing unit and glazing unit configuration, can be the model of double glazing unit, or is to integrate the function such as UV glazing together, can also be a chance to go to complete the printing paper glazing before or after printing glazing machine, is entirely on-demand configuration。
UV ink and gloss oil in printing industry get rapid popularization, they are better able to adhere to the non absorptive materials, not only is not easy to fall off, also has the very high gloss. Speed bully CD74UV offset press followed the development trend, at the same time, it is also the world's first by German printing and paper insurance and protection agency awarded the title of "best UV printing offset press. All elements are involved in the UV printing CD74 set at a suit, so to speak, CD74 opened up the production process, equipment operation and investment protection.
With the enlargement of the transparent plastic folding box packaging market, in order to make plastic boxes in the field of machining can increase the communication between the middle and lower reaches of the enterprise, make the printing of transparent plastic folding box molding technology to the next level, May 16, 2006, we held the first south China transparent plastic folding box processing technology seminar. Meeting around a plastic box box type design, plastic boxes, printed after the molding technology and glue, plastic boxes, material selection, plastic boxes, with topics such as spray adhesive system has carried on the warm discussion, henkel, Avon, Colgate, blue moon, and made white well-known daily chemical industry such as the end user also made a speech at the scene.
Transparent plastic folding box is still in the initial stage of development, its processing technology still need to constantly improve and perfect, the enterprise of exploration and development is particularly important on its own. Look from the meeting, in addition to the application technology of UV printing plastic box, some enterprises have adopted the common offset press + fast dry ink to printing plastic box, and the quality is good.
