About barrier material and container

Which has the function of blocking the moisture materials can be used as moisture-proof packaging materials. The most commonly used is to have a certain thickness of various kinds of metal, glass, ceramic, plastic and all kinds of processed wood, paper, traditional materials such as cotton, hemp. Modern hunan prevention packaging used in many plastic film, such as high density polyethylene ( HDPE) Low density polyethylene ( LDPE) The polypropylene ( PP) , two-way stretch polypropylene ( BOPP) 。 Poly (ethylene nitrogen PVC) , poly (n, PU) , ce, PET) , poly (vinylidene second catch PVDC) Order, poly amine ( PA) And so on. With PET, the most widely used in moisture-proof packaging materials because of its low permeability, easy to heat sealing. And the use of PVC is restricted, because there are free to grasp of material, the corrosion products. There are many better blocking performance of moisture-proof composite material, such as aluminum foil/PE. Paper IPE, PPIPP, BOPP/PP, PE/aluminum foil, PE, cloth/aluminum foil IPE, PE/al/PE/cloth, etc. In addition to a variety of special processing of waterproof paper, moisture-proof glass paper, waxed paper, etc. Used in moisture-proof packaging container has expanded polystyrene ( 每股收益) Box, high density polyethylene ( HDPE) Box, multi-layer composite membrane envelope, metal containers, peng big calcium plastic corrugated boxes, wooden boxes, glass fiber reinforced plastic boxes, bo rui male, etc.
