Wholesale 0.3mm 0.5mm 1mm 2mm PET Sheet Manufacturer In China

PET is a material with good crystallinity, colorless and transparent, and extremely tough. It has the appearance of glass, is odorless, tasteless, non-toxic, flammable, has a yellow flame with a blue edge when it burns, and has good air tightness. Polyethylene terephthalate (PET) PET has a small expansion coefficient and a low molding shrinkage rate of only 0.2%, which is one-tenth of polyolefin and smaller than PVC and nylon, so the size of the product is stable. The mechanical strength is the best, and its expansion degree is similar to aluminum. The film strength is 9 times that of polyethylene, 3 times that of polycarbonate and nylon, and the impact strength is 3 to 5 times that of ordinary films. The film also has moisture-proof and fragrance-preserving properties. Although polyester has the above-mentioned advantages, its film is more expensive, difficult to heat-seal, and easily charged with static electricity, so it is rarely used alone. Most of them are coated with a resin with better heat-sealability to make a composite film. The PET bottle using the two-axis stretch blow molding method can give full play to the characteristics of PET, that is, it has good transparency, high surface gloss, and a glass-like appearance. It is the most suitable plastic bottle to replace glass bottles. In recent years, the production of PET bottles has developed rapidly, and heat-resistant PET bottles are widely used in beverages that require hot cans such as tea beverages and fruit juice beverages.
