Problems solved by technology

PE and PVDC generally have insufficient high-temperature resistance, and PVC cling film contains carcinogens, which are harmful to the human body. Now we are studying a high-temperature-resistant and green plastic cling film, which is made of PMP (polymethylpropylene), which is safe. Non-toxic, high transparency, high temperature resistance, etc.

Abstract

The invention discloses a high temperature resisting, green and environment-friendly preservative film and a production process thereof. The preservative film is characterized by comprising the following raw materials in parts by weight: 80-120 parts of polymethacrylonitrile, 0.5-1.5 parts of antioxidant, 0.5-1.5 parts of clouding agent, 0.5-1.5 parts of toughening agent and 1.5-2.5 parts of sensitizing agent. The preservative film has the beneficial effects that a PMP (Polymethacrylonitrile) material adopted in the preservative film has the properties of high temperature resistance, safety and nontoxicity; due to adoption of the sensitizing agent, the preservative film can be easily decomposed, and moreover, the decomposed film is non-pollution and is green and environment-friendly.

Description

technical field [0001] The invention relates to the field of materials, in particular to a high-temperature-resistant green and environment-friendly plastic wrap and a production process thereof. Background technique [0002] Plastic wrap is a kind of plastic packaging product, usually made of ethylene as the masterbatch through polymerization reaction, mainly used in microwave oven food heating, refrigerator food preservation, fresh and cooked food packaging and other occasions, in family life, supermarkets, hotels and restaurants It is widely used in the field of industrial food packaging. According to the different materials used and the addition of plasticizers, plastic wrap is divided into various types, which can be applied to different occasions. Preservative film has been favored by people for its convenience, economy and attractive appearance. However, due to the general addition of plasticizers in the production process, the impact of plastic wrap on human health...
