Background

The plastic wrap is a plastic packaging product, and is usually prepared by taking ethylene as a master batch through polymerization reaction, and the plastic wrap can be divided into three categories: the first is polyethylene, abbreviated as PE; the second is polyvinyl chloride, PVC for short; the third is polyvinylidene chloride, abbreviated as PVDC. The preservative film is commonly used in the fields of microwave oven food heating, refrigerator food preservation, fresh and cooked food packaging and the like, and is widely applied in the fields of food packaging of family life, supermarket stores, hotels and restaurants and industrial production. Among the three preservative films, the preservative film made of two materials, namely PE and PVDC, is safe for human bodies and can be used safely, and the PVC preservative film contains carcinogenic substances and is harmful to human bodies, so that the PE preservative film is selected when the preservative film is selected. From the physical perspective, the preservative film has proper oxygen permeability and moisture permeability, the content of oxygen and moisture around the preserved product is adjusted, and dust is blocked, so that the preservation period of the food is prolonged. Therefore, different food products need to be selected from different preservative films.

The existing preservative films are basically divided into three types and are mainly applied to food packaging by using a PE preservative film, but the viscosity of the PE preservative film is poorer than that of a PVC preservative film, the viscosity of the material is not easy to control, the PE preservative film is too high and is not easy to tear, and the PE preservative film cannot achieve the sealing effect when being too low.

Therefore, a composite preservative film is provided.
