Salt, cereal and cereals, pet food, stretch up and down film, sauces, meat products, liquid packaging, beans, and so on. Product packaging, polyamide (PA) and polyvinyl alcohol (PVA)
Polyamide (PA) excellent solvent resistance, heat resistance, abrasion resistance, chemical resistance and self-lubricating, and low coefficient of friction, a certain flame retardant, easy processing purposes: canned food, food and beverage Packaging two, polyvinyl alcohol (PVA) after ultraviolet light blue and white fluorescence. Water, can be dissolved in water, can pass through the water vapor, but difficult through the alcohol vapor, but also through the organic solvent vapor, inert gas and hydrogen Uses: water-soluble packaging materials, flavor food packaging, oil food packaging poly (PET) and polycarbonate (PC) First, polyester (PET) with high barrier properties, good chemical stability, with other plastic does not have high strength and toughness, high wear resistance, high resistance to high and low temperature

Uses: seasoning commodity bottles, edible oil
Packaging, beverage bottles, especially carbonated drinks Second, polycarbonate (PC) colorless or slightly yellow transparent particles, tasteless, odorless, non-toxic, good cold resistance, and good heat resistance, heat, Oxygen, atmospheric and ultraviolet light have good stability, but long-term use in outdoor or under strong light, the surface will become dark, loss of luster, yellowing, and even cracks. Uses: pots, boxes, bottles, canned ethylene - vinyl acetate copolymer (EVA) and ethylene - vinyl alcohol copolymer (EVAL)
First, Ethylene-Vinyl Acetate Copolymer
EVA) EVA for gas and moisture permeability than low-density polyethylene, so it should not be a high degree of anti-penetration material. EVA oil resistance, chemical resistance than polyethylene, PVC slightly worse. EVA is more flexible and flexible than polyethylene Uses: Production of packaging film, suitable for elastic packaging film, heat shrinkable film, agricultural film, food packaging film, laminated film Second, ethylene - vinyl alcohol copolymer (EVAL) has a strong Oil resistance and resistance to organic solvents, with high mechanical strength, elasticity, surface hardness, abrasion resistance and
Weather resistance, and strong antistatic properties, thermal stability of the highest Uses: There are hard and flexible packaging and including sterile, hot injection and pressure of all types of food processing
??Ionic bond polymer and other plastic resin First, the ionic bond polymer linear or branched organic polymer chain contains a small number of ionic bond side groups, can be ionized by the interaction of cross-linking. The temperature is relatively high, these ion bonds can be dispersed, which presents thermoplastic, so also known as thermoplastic ion polymer use: packaging complex shape of the food, fat food two, other plastic resin
