The application field of alcohol soluble ink

gravure printing ink in plastic flexible packaging application key words: plastic flexible packaging application in the production of cooking resistant packaging bags, it is also necessary to select high-temperature resistant materials and cooking resistant two-component composite adhesive. The surface tension of plastic intaglio printing ink is generally 36 dynes, while the surface tension of PE and OPP is generally only about 32 dynes, which requires that during intaglio printing, the film should undergo corona treatment to destroy the molecular structure of the plastic surface, improve the film surface tension to more than 38 dynes, make the ink and film stick together, and the ink can not be removed by hand rubbing and adhesive tape, so as to meet the printing quality requirements. Plastic gravure printing ink due to chlorination in the production of poly 1 The use of platform compounds in the production of integrated circuit materials has an impact on the ozone layer. Toluene is widely used in intaglio printing to dissolve and adjust the viscosity of the ink, which is harmful to the health and safety of workers. This requires the ink manufacturer to develop low toxicity and non-toxic alcohol soluble and water-soluble intaglio plastic printing ink as soon as possible. We use plastic flexographic ink in the production of paper plastic composite coiled materials (for users to pack drugs and make tea in bags) and liquid packaging film coiled materials

this ink is alcohol soluble. The added solvents are alcohols and esters. It has low toxicity and meets the hygienic requirements of tasteless and benzene free. In a word, the selection and application of plastic gravure printing ink should be based on the performance of different gravure printing machines and the proficiency of operators. You should know what material to print on, how fast the gravure press is, how dry the ink is, whether the printing color is consistent with the original, whether the post press processing meets the requirements and the purpose of the final product. Different inks should be selected for different specifications and different plastic flexible packaging bags (films)

exquisite plastic printing products can be produced only by selecting appropriate inks and materials and careful operation. When using the plastic intaglio printing ink, which is a new type of light-weight ground decoration material composite ink popular in the world, we should pay attention to it, because we are not afraid of the radiation environment, the high and low temperature in space, the long fatigue aging life, and can be preserved for a long time. When designing the ink, the ink manufacturer has the difference between the fast drying ink of the high-speed machine and the dry ink of the low-speed machine. 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 dries in the pit of the gravure point; Gravure printing machine speed fast printing parts can not dry. For steaming resistant plastic flexible packaging or printing aluminum foil, we should choose steaming resistant two-component gravure ink and special ink for aluminum foil. Otherwise, it will not be able to resist cooking, and the ink in the inner layer after compounding will become thin, discolored, and the picture and text are not clear. In the production of cooking resistant packaging bags, it is also necessary to select high-temperature resistant materials and cooking resistant two-component composite adhesive. The surface tension of plastic intaglio printing ink is generally 36 dynes, while the surface tension of PE and OPP is generally only about 32 dynes, which requires that during intaglio printing, the film should undergo corona treatment to destroy the molecular structure of the plastic surface, improve the film surface tension to more than 38 dynes, make the ink and film stick together, and the ink can not be removed by hand rubbing and adhesive tape, so as to meet the printing quality requirements. Due to the influence of chlorinated polymer on the ozone layer in the production of plastic gravure printing ink, toluene is widely used in gravure printing to dissolve and adjust the viscosity of the ink, which is harmful to the health and safety of workers. This requires the ink manufacturer to develop low toxicity, non-toxic alcohol soluble and water-soluble gravure plastic printing ink as soon as possible. We use plastic flexographic ink in the production of paper plastic composite coiled materials (for users to pack drugs and make tea in bags) and liquid packaging film coiled materials

this ink is alcohol soluble. The added solvents are alcohols and esters. It has low toxicity and meets the hygienic requirements of tasteless and benzene free.

You should know what material to print on, how fast the gravure press is, how dry the ink is, whether the printing color is consistent with the original. With the continuous improvement of control accuracy, whether the post press processing meets the requirements and the purpose of the final product. Different inks should be selected for different specifications and different plastic flexible packaging bags (films). Only by selecting the appropriate ink and materials, combined with careful operation, can we produce exquisite plastic printing products
