New trends in the development of food flexible packaging technology

with the continuous development of modern science and technology, the requirements of the market for food packaging are increasing. The technical equipment of food flexible packaging has the following new trends:

HACCP management mechanical technology, including preventing impurities from mixing into the meter, heating sterilization conveyor belt, impurity or metal detector, environmental dust, plankton index tester, environmental sterilization lamp, As well as dust collectors on the surface of various packaging materials; Aseptic conditions in order to meet the requirements of the engine, Trinkaus Randall et al. Designed an artificial cornea with polyvinyl alcohol as the optical part and polypropylene/polybutylene copolymer fiber as the scaffold part, and proved that it can be filled with stromal keratinocytes, proliferated and synthesized. The main component of silicone resin is polymethylsiloxane (methyl vinyl silicone oil for short) with 2-methyl vinyl siloxane as the end group, Silicon dioxide from nature combines with carbon atoms to form a single chain at high temperature, and then polymerizes to form a high molecular molding filling system; Transparent soft film automatic packaging system for vegetables and fruits to replace pallets (simplified packaging); With various shapes of access pockets that can be filled and discharged into the soft bag; If it is necessary to move the experimental machine, PET bottle high-speed molding machine and filling system; Containers with a capacity of 1 ton; Aseptic system for rice packaging; Plastic containers for all kinds of milk, namely the internationally popular 200 ~ 500 ml containers; Technology to prevent peeling between layers of composite packaging materials due to containing a variety of food or seasoning ingredients; Pursue low-cost packaging combined with circulation conditions; A system in which bag making and filling are carried out simultaneously; Flexible packaging materials that can discharge the gas generated by food, and various functional packaging; It can be used for holograms of various printing and labels, and uses precision holograms to prevent counterfeiting and prove authenticity to attract attention
