Problems solved by technology

[0003] Many packaged foods are fried foods with high temperature. If they are carried by plastic made of ordinary food packaging film, the chemical substances in the packaging film will be dissolved out, which is harmful to health. In addition, when microwave heating is required, food cannot be used directly. Packaging film to pack food for heating, very troublesome

Abstract

The invention discloses a high-temperature resistant fresh-keeping film and a production process thereof. To solve the technical problems in the prior art, the fresh-keeping film is characterized by comprising the following components in parts by weight: 100 parts of poly methacrylic, 2-6 parts of dioctyl phthalate, 1-2 parts of polyvinyl alcohol, 2-4 parts of dioctyl adipate, 2-4 parts of a flexibilizer, 2-5 parts of polyimide, 2-4 parts of dodecyl acid dioctyltin, 2-5 parts of polysulfonyldiphenylene phenyl phosphonate, 1-2 parts of polyoxyethylene lauryl ether of which the number of EOs is 10, 1-3 parts of silicon dioxide and 100 parts of water. The fresh-keeping film is easy to pull out and cut, and can be easily bonded with glass ceramic and stainless steel cooked wheaten food containers; the fresh-keeping film is an environment-friendly fresh-keeping film produced by adding a plurality of additives into polyethylene plastic for mixing, so that the efficacies of high-temperature resistance, good tearing resistance, good fresh-keeping effect, long quality guarantee period and bacterium resistance can be achieved.

Description

technical field [0001] The invention relates to a fresh-keeping film, in particular to a high-temperature-resistant fresh-keeping film. Background technique [0002] Plastic wrap is a kind of plastic packaging product commonly used by people to keep fresh food, and now many families cannot do without them. Microwaves will be used to heat food, as will storing food in the refrigerator. [0003] Many packaged foods are fried foods with high temperature. If they are carried by plastic made of ordinary food packaging film, the chemical substances in the packaging film will be dissolved out, which is harmful to health. In addition, when microwave heating is required, food cannot be used directly. It is very troublesome to pack food with packaging film for heating. Contents of the invention [0004] The invention provides a high temperature resistant fresh-keeping film and a production process thereof. [0005] In order to solve the above technical problems, the present inven...
