Environment-friendly preservative film

Abstract

The invention relates to an environment-friendly preservative film which comprises a substrate, a high-temperature-resistant agent, a toughener, a preservative, an antioxidant, an antiseptic and a coating agent, wherein the substrate is polyethylene plastic; the high-temperature-resistant agent is polyimide; the toughener is polyvinyl acetate; the preservative is deacetylated chitin; the antioxidant is tert-butylhydroquinone; the antiseptic is propyl p-hydroxybenzoate; and the coating agent is pentalyn. Multiple additives are added into the polyethylene plastic, so that the environment-friendly preservative film formed by mixing has the advantages of high-temperature resistance, favorable tear resistance, favorable preservative effect, long expiration date and microbial resistance. The product is prepared from nontoxic pollution-free materials, and thus, is environment-friendly, nontoxic and harmless.

Description

technical field [0001] The invention relates to a chemical material, in particular to an environment-friendly fresh-keeping film. Background technique [0002] Plastic wrap is a kind of plastic packaging product commonly used by people to keep fresh food. Nowadays, people cannot do without it in many places in daily life. For example, it will be used for heating food in a microwave oven, and it will also be encountered when storing food in a refrigerator. But there are many deficiencies in the existing plastic wrap, such as when the former is heated in a microwave oven, the plastic wrap tends to break, and even sticks together with the food, so that the taste of the food is destroyed, and the harmful substances of the plastic wrap can stick to the food simultaneously. First, it will cause harm to the human body after eating; the latter will lose freshness after being placed in the refrigerator for a long time, causing the food to deteriorate.

But there are many deficiencies in the existing plastic wrap, such as when the former is heated in a microwave oven, the plastic wrap tends to be broken, and even sticks together with the food, so that the taste of the food is destroyed, and the harmful substances of the plastic wrap can stick to the food simultaneously. First, it will cause harm to the human body after eating; the latter will lose freshness after being placed in the refrigerator for a long time, making the food deteriorate.

[0003] The existing preservative film has relatively simple functions, short preservation time, poor high temperature resistance, and there are toxic substances in the plastic preservative film, which is not conducive to the current concept of environmental protection
