Hygiene and safety, in line with the requirements of food packaging. Pet is commonly known as polyester. High transparency, good gloss. It has excellent gas and oil resistance and aroma retention properties. It is hard and tough with high tensile strength. Good chemical stability, alkene acid and alkali resistance. It can be used at 150 ℃ for a period of time. Good health and safety. It is widely used in poultry packaging. The composite film based on pet can be used for cooking food packaging. Polyamide PA, commonly known as nylon, has strong air resistance, but poor water vapor barrier, strong water absorption, and swelling with the increase of water absorption, resulting in a sharp decline in air and moisture resistance, and the stability of its strength and packaging size are also affected. Chemical stability is good, is a non-toxic packaging material. Therefore, it is often used in the thermal seal layer and moisture-proof coating of composite materials. Polypropylene PP polypropylene is a kind of light plastic with good transparency, gloss, good physical and mechanical properties, such as tensile strength, hardness and toughness, good heat resistance. It can be used continuously at 120 ℃ and can be cooked in boiling water. It has stable chemical properties and is stable to acid and alkali salts and many solvents in a certain temperature range. Cost saving, the use of winding film packaging products, can effectively reduce the cost of use, using winding film only about 15% of the original box packaging, about 35% of the heat shrinkable film, about 50% of the carton packaging. At the same time, it can reduce labor intensity of workers, improve packaging efficiency and packaging grade. At present, the widely used plastic packaging materials in the market are polyethylene, polyethylene, which is not transparent, has certain air permeability, tensile strength and tear strength, but also has certain flexibility and good moisture resistance. At the same time, the adjustable tensile force can make the hard products close to each other and make the soft products compact, especially in the tobacco industry and textile industry, which has a unique packaging effect. Dry food requires high moisture resistance. Aromatic food requires high resistance to odor. Fruit and vegetable fresh food also requires a certain amount of oxygen, carbon dioxide and water vapor permeability. At the same time, it should have good physical and mechanical properties, including tensile strength, tear strength, impact strength and so on. It should also have good chemical stability and should not have any chemical reaction with the inner food to ensure the safety of the food. It also has high temperature resistance, suitable for high temperature disinfection and low temperature storage of food. Therefore, most of the food packaging in the market is based on composite plastic film packaging, especially high barrier materials have become the main body of food packaging. Therefore, the quality and flavor of the contents should be considered first. At the same time, in the selection of plastic film bags, we must fully understand the relevant properties of plastics, so as to achieve reasonable selection. In particular, plastic film bags used for food packaging must meet the hygienic standards for plastic products of corresponding materials. It has good mechanical properties, g
