Many plastics molding and product use, due to heat, light or oxygen, premature degradation, oxidation and chain scission, crosslinking and other phenomena, leaving the material properties deteriorate. In order to stabilize the quality of plastic products, extend the life of food bags packets, usually by adding a stabilizer in its components. Usual stabilizers have stearic acid, lead white, epoxides such as PE film: Transparency slightly less cpp, but softer than cpp, PE stretch film performance is better, pull-off force is better. There are white and transparent PE two kinds of PE (HDPE / LDPE / LLDPE), feel softer. PA film (nylon): PA relatively tough material, transparency and wear puncture-resistant, easily oxidized, easy to shrink and wrinkle, this material is suitable for installation similar bone products. OPP film: Material hard, and can not stretch, sealing type is very good, but more general transparency of food bags, material more brittle, feel bad. CPP film: CPP material transparency but better than the OPP PE ratio is poor, soft and high-temperature materials that can be used to make printed materials, but not easy printing. Composite food bags for food, electronics, chemicals, pharmaceuticals, tea, precision instruments and cutting-edge products such as vacuum packed defense or general packaging. Raw material: OPP, PE, POF, PPE, PP, etc. composite membrane process is divided: while envelope, bottom seal bag, sealed in bags, side seal. Require four different machines. PE film: Transparency slightly less cpp, but softer than cpp, PE film is better tensile properties, tensile strength is better. There are white and transparent PE two kinds of PE (HDPE / LDPE / LLDPE), feel softer. Food bag factory, Red Plastic Factory (certified), Jilin food bags provided by Xiong Red Plastic Factory.
