Application of Gravure Printing Inks in Plastics Flexible Packaging Keywords: Plastic flexible packaging applications When manufacturing retort pouches, heat resistant materials and retort-resistant two-component adhesives are also required. The surface tension of plastic gravure ink is generally 36 dyne, while the surface tension of PE and OPP is generally only about 32 dyne. This requires that in gravure printing, the film undergo corona treatment to destroy the molecular structure of the plastic surface and improve the film. Surface tension, so that it reaches 38 dynes or more, so that ink and film affinity and adhesion, hand smashed and adhesive tape can not tear the ink before they meet the printing quality requirements. Because of the influence of chlorinated polymers on the ozone layer during the production of plastic gravure inks, a large amount of toluene is used in gravure printing to dissolve and adjust the viscosity of the ink, causing damage to the health and safety of workers, which requires the ink manufacturer to develop as soon as possible. Poisonous, non-toxic alcohol-soluble and water-soluble gravure plastic printing ink. We use plastic flexo inks in the production of paper-plastic composite webs (for users to self-assemble machine-packed pharmaceuticals, tea bags, etc.) and the production of liquid packaging film webs.
This ink is alcohol-soluble, the solvents added are alcohols and esters, low toxicity, to achieve odorless, no benzene hygiene requirements. In short, the selection and application of plastic gravure printing inks depends on many factors such as the performance of different gravure printing machines and the proficiency of operators. To know what material is printed on, what is the speed of the gravure printing machine, how dry the ink is, whether the printing color is consistent with the original, and whether the post-press processing meets the requirements and the intended use of the final product. Different inks should be used for different specifications and different plastic flexible bags (films).
Only by choosing suitable inks and materials, and careful operation, can we produce beautiful plastic printing products. When using plastic gravure composite inks, be careful, because ink manufacturers have the difference between high-speed machine fast dry ink and low-speed machine dry ink when designing ink. When printing, the choice of ink should be determined by the rotation speed of the gravure printing machine. Otherwise, the rotation speed of the gravure printing machine is slow, and the ink is dried in the pits of the gravure network; the gravure printing machine can not dry quickly after the printing speed is high. For retort-resistant plastic flexible packaging or printed foils, choose two-component gravure-resistant gravure inks and foil-specific inks. Otherwise it will not be resistant to cooking, there will be compound after the inner layer of the ink after cooking thinning, discoloration, the picture is not clear and so on. In the production of retort pouches also need to choose high-temperature materials and cooking resistance of two-component adhesive.
