Changshu vacuum bags low cost: the relative glass packaging, aluminum foil packaging and other plastic packaging, to achieve the same barrier effect, co-extruded film has a large advantage in terms of cost. Since the process is simple, the production cost of the dry film composite films and other composite films can be reduced by 10-20% as compared to 4, the high strength vacuum bags: vacuum bags having stretch characteristics in the process, the plastic After stretching can be a corresponding increase in strength, can also be added as nylon, polyethylene and other plastic materials in the middle, it has more than ordinary plastic packaging composite strength, delamination phenomenon does not exist, softness, excellent sealing performance. 5, vacuum bags capacity than smaller: coextruded film can be vacuum shrink packaging, capacity approximately 99.9% by volume, which is glass, cans, paper packaging can not be compared. 6, vacuum bags friendly: no added binder, no residual solvent contamination, green. 7, a wide range of vacuum bags Application: vacuum bag applications requiring vacuum packaging industry textile, food, electronics, hardware, and chemical. Materials and packaging machinery and raw material costs reduced food packaging. Food packaging industry in the future will be more and more use of light weight and low cost materials to reduce production costs and pollution. More and more features are designed towards saving materials, packaging process of saving goal. This is also the current food packaging industry and enterprises are facing the biggest confusion.
