Abstract

The invention discloses a plastic film capable of being applied to the inner surface of a lunchbox and a preparation method thereof. The plastic film comprises an upper surface layer, a middle layer,and a lower surface layer. The upper surface layer and the lower surface layer are made of following raw materials: polyethylene, tea polyphenol, purple potato starch, methyl paraben, and sodium carboxymethyl cellulose. The middle layer is made of following raw materials: polyethylene, tea polyphenol, purple potato starch, methyl paraben, sodium carboxymethyl cellulose, and wood chips. The raw materials cooperate with each other, the prepared plastic film is green and environmentally friendly, can be degraded rapidly, and is capable of efficiently adsorbing oil stains, the preparation method is simple, and the application range is wide.

Description

technical field [0001] The invention relates to the field of film production and processing, in particular to a plastic film that can be used on the inner surface of a lunch box and a preparation method thereof. Background technique [0002] With the development of science and technology and the progress of the times, the living standards of human beings are gradually improving, and more and more people pay special attention to quality and service. The fast-paced pace of life has become the mainstream of the times, and the fast-food industry has developed rapidly. Takeaways and packed lunches can be seen everywhere, and fast-food boxes are widely used, and the quality requirements are getting higher and higher. After all The large-scale use will cause huge pressure on the environment. At the same time, whether the fast food box itself can be really healthy and harmless is also a topic of great concern to consumers. At present, it is particularly important to prepare a plast...
