Many plastics molding and product use, due to heat, light or oxygen, premature degradation, oxidation and chain scission, crosslinking and so on food bags packet, leaving the material properties deteriorate. To stabilize the plastic quality, long life, 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 food bags, PE film is better tensile properties, tensile strength is better. There are white and transparent PE two kinds of PE (HDPE / LDPE / LLDPE) food bags pictures, 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 films: Materials harder food bag factory, and can not stretch, sealing type is very good, but transparency is more general, more brittle material, feel the difference. 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. This bag is made of composite material made of layers of different materials food bags food bags, also called composite bags. General requirements for food bags composite bag. Food bag bag with excellent barrier properties, excellent resistance to pasteurization, refrigeration-resistant features, is preferred to achieve food bags. Bag can be used for jelly cool, acid (fresh) milk, drinks, jams and other liquid drinks food bags, or for milk, candy and other particles, powder-like food bags. pe food bags food bags _ _ Chengdu Hongqi Plastic Factory provided by Xiong Red Plastic Factory.
