Polyethylene film for pleurotus eryngii packaging

Abstract

The invention discloses a polyethylene film for pleurotus eryngii packaging. The polyethylene film comprises the following raw materials by weight: 70-95 parts of polyethylene, 20-35 parts of polylactic acid, 0.3-0.8 part of an antibacterial agent, 1-2 parts of polyglyceryl fatty ester, 0.2-1 part of sorbitol, 0.5-3 parts of corn oil, 0.3-1.8 parts of stearic acid, 0.9-2 parts of a cerium complex,2-7 parts of graphene microsheet, 3-8 parts of montmorillonite, 2-9 parts of medical stone, and 0.05-0.1 part of an antioxidant. The antibacterial agent is a mixture of antibacterial peptide, cinnamon essential oil, cymbopogon citratus essential oil, a forsythia extract, a scutellaria baicalensis extract and a houttuynia extract in a weight ratio of 1-5:3-9:2-11:2-7:1-5:3-11. The polyethylene film for pleurotus eryngii packaging provided by the invention has the characteristics of excellent antibacterial performance, good fog resistance and high light transmittance, can inhibit the growth andreproduction of microorganisms when used for pleurotus eryngii packaging, ensures the quality of pleurotus eryngii and prolongs the shelf life.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable packaging, in particular to a polyethylene film for packaging pleurotus eryngii. Background technique [0002] Pleurotus eryngii will rot and deteriorate after being placed for a period of time, or the water will evaporate and wilt, which will greatly affect its quality and cause economic losses. Therefore, wrapping on the surface of Pleurotus eryngii is mainly used to isolate the entry of decomposing microbial bacteria and foreign pollutants, and the food packaging film to prevent food deterioration is very important for Pleurotus eryngii. [0003] Polyethylene film is currently the most widely used and most used plastic packaging film. It has the advantages of high transparency, easy processing, chemical resistance and low manufacturing cost. It has been widely used in vegetable packaging, but ordinary The anti-fog performance of polyethylene film is not very good, the light transmi...

Problems solved by technology

[0003] Polyethylene film is currently the most widely used and most used plastic packaging film. It has the advantages of high transparency, easy processing, chemical resistance and low manufacturing cost. It has been widely used in vegetable packaging, but ordinary The anti-fog performance of polyethylene film is not very good, the light transmittance is low, and the antibacterial performance is not good, which limits its application in the packaging of Pleurotus eryngii
