Environment-friendly degradable food-grade antibacterial plastic packaging film and preparation process thereof

Abstract

The invention discloses an environment-friendly degradable food-grade antibacterial plastic packaging film and a preparation method thereof. A formula of the environment-friendly degradable food-grade antibacterial plastic packaging film comprises 200-300 parts of polypropylene, 50-120 parts of plant starch, 30-80 parts of sarcandra glabra fiber, 3-8 parts of polysilicone oil, 3-6 parts of ground calcium carbonate, 3-7 parts of glycerin, 2-5 parts of hydroxypropyl methyl cellulose, 1-3 parts of graphene, 5-12 parts of bamboo powder, 10-15 parts of antibacterial powder, 8-18 parts of a photosensitizer, 1-7 parts of neopentyl polyol polyester, 3-8 parts of a toughening agent, 2-4 parts of a food preservative, 1-6 parts of a degradation accelerant and 8-12 parts of vegetable oil. The environment-friendly degradable food-grade antibacterial plastic packaging film disclosed by the invention is degradable, and the bamboo powder, the antibacterial powder and the food preservative are added into the formula, so that the plastic packaging film has a certain antibacterial and preservative effect, and the problem is solved that the plastic packaging film cannot be degraded due to the poor antibacterial effect of the plastic packaging film to a certain extent, and the food packaged by the plastic packaging film is easy to deteriorate.
