The thermoplastic resin having a heat softening, hardening of the cooling performance, and no chemical reaction, both heating and cooling are repeated many times, can maintain this performance. Where a thermoplastic resin which are of linear molecular structure. It includes all polymeric resin and containing a partial condensate resin. The thermoplastic resins include: polyethylene, polyvinyl chloride, polystyrene, polyamide, polyacetal, polycarbonate, polyphenylene oxide, polysulfones, rubber or the like. Advantages of the thermoplastic resin molding is simple, has a high mechanical energy. The disadvantage is that the heat resistance and rigidity is poor. Food bag is one of the food industry in the process of major projects. It protects food bag of food, the food leaves the factory to the consumer in the hands of the circulation process custom food bag, food bags to prevent biological, chemical food bags, food bags physical damage to external factors, it can also have food bags maintain the quality of the food itself stable function, it's easy to eat food, but also the appearance of the first performance of the food bag food manufacturers to attract the consumer's image, with the value of material costs outside. 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. PA film (nylon): PA relatively tough material wholesale food bags, transparency and wear puncture-resistant, easily oxidized, easy to shrink and wrinkle, this material is suitable for installation similar bone products.
