Drug packaging - ink trend

after years of development, the production process of composite film has been improved by adopting full digital speed regulation system for plastic calenders. Therefore, there will be no major changes in the near future. Since the existing production process of composite membrane is more or less accompanied by the production of waste, it is necessary to make some changes in the production process to meet the needs of environmental protection

(1) in the process of plastic gravure printing, benzene free ink is used to replace the current ink based on benzene solvent. At present, although many domestic manufacturers have introduced benzene free inks, the important performance is that the buffer loss has not fully met the needs of plastic printing, and the price is expensive. The unit price is 2 ~ 4 times that of ordinary inks, which is not conducive to reducing the printing cost. Therefore, benzene free ink will replace ordinary ink. Enterprises should install waste gas treatment devices to reduce the emission of organic substances (especially Benzene Series) in the printing process

(2) in the dry compounding process, the solvent used is ethyl acetate. Although the emission of ethyl acetate gas is not clearly specified in the integrated emission standard of air pollutants (g), the gas is harmful to human respiratory tract, so it should be used as little as possible. Alcohol soluble adhesives that can replace polyurethane adhesives with ethyl acetate as solvent have been developed. The adhesive uses alcohol as solvent, has no pollution and low cost, and will be widely used

raw materials and material structure

the materials required for the production of composite films mainly include polypropylene, polyethylene, polyester, polyester aluminum plating, aluminum foil, etc., which will remain the main raw materials for the production of composite films in the future. It will still be widely used for a long time. Because the composite films and bags composed of these raw materials are disposable consumer goods, which can rarely be recycled, people try to replace them with degradable plastic films with the same performance. It is worth noting that as people pay more and more attention to environmental protection, the paper with the original surface of the sample is more and more used in the production of composite film. The composite film of paper/flow layer/aluminum foil/flow layer/PE structure will become more and more popular

in a word, there will be no revolutionary changes in the process and raw material utilization of composite membrane production in the coming years. For production enterprises, while paying full attention to environmental protection issues, they should strive to improve their own quality, product quality and grade, and improve their management level according to the use of Tensile testers in different industries, so as to meet the increasingly international market competition
