Wujiang nylon vacuum bag Advantages / Features: 1, high barrier: the use of high barrier properties of different plastics material co-extruded film, to oxygen, water, carbon dioxide, odor barrier effect. 2, stable performance: oil, resistant to moisture, resistant to freezing, durability, preservation, security smell, can be used for vacuum packaging, aseptic packaging, inflatable packaging. 3. 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, high strength: co-extruded film having a tensile characteristics in the process, the plastic can be stretched a corresponding increase in strength, may be added in the middle of nylon, polyethylene and other plastic materials, it has more than ordinary plastic packaging composite strength, there is no delamination phenomenon, softness, excellent sealing performance. Excessive packaging, pollution may increase. Now the food, as long as it can be sent out as gifts, is bound in a complex with attractive packaging, generous layer after layer of packaging materials of various materials. This will not only directly affect the price of goods, there may be a serious harm to human health. For example, the use of PVC material made of moon cake tray to contain large amounts of toxic and hazardous substances. Moon cake contains more fat, these toxic and hazardous substances dissolved in the oil will be migrated to the moon cake, it will cause harm to human health.
