Abstract

The invention discloses an environment-friendly and degradable food-grade plastic packaging film. The environment-friendly and degradable food-grade plastic packaging film is prepared from the following raw materials in parts by weight: 65 to 76 parts of modified linear low-density polyethylene particles, 25 to 35 parts of plant starch, 7 to 14 parts of sarcandra glabra fibers, 8 to 18 parts of filling master batch, 3 to 6 parts of a dispersant, 2 to 4 parts of a coupling agent, 2 to 6 parts of a compound plant antibacterial agent, 3 to 5 parts of an amphoteric surfactant, 5 to 7 parts of graphene oxide, 3 to 5 parts of xanthan gum, 1 to 3 parts of cellulose acetate, 2 to 4 parts of a light degradation agent, 1 to 3 parts of an ultraviolet absorbent, 2 to 4 parts of coconut oil, 1 to 3 parts of glycerol, 1 to 3 parts of prunus humilis bunge fibers, 1 to 3 parts of a waterproof agent and 2 to 4 parts of an antioxidant. According to the environment-friendly and degradable food-grade plastic packaging film, the plant starch and the sarcandra glabra fibers have abundant sources and a cheap price, and are environmentally friendly; the prepared plastic thin film has the advantages of high strength, low production cost, biodegradability, antistatic performance, oxidization resistance and ultraviolet resistance, and the problem of white pollution can be alleviated.

Description

technical field [0001] The invention relates to the field of plastics, in particular to an environmentally friendly and degradable food-grade plastic packaging film. Background technique [0002] In the food packaging industry, vacuum packaging, inflatable packaging, modified atmosphere packaging, high-temperature cooking packaging, aseptic packaging and coating, and printing composite substrates are widely used. Vacuum packaging is to put food into the packaging bag and pull it out of the packaging bag After reaching the predetermined vacuum degree, it is sealed. Its main function is to remove oxygen to prevent food from deteriorating. Inflatable packaging is to inject nitrogen, carbon dioxide, oxygen single gas or a mixture of two or three gases after vacuuming. Modified atmosphere packaging uses modified atmosphere fresh-keeping gas (2-4 kinds of gases are mixed according to the ratio of food characteristics) to replace the air in the packaging bag, change the external e...
