Abstract

The invention discloses a food-grade antibacterial freshness protection plastic packing bag. The food-grade antibacterial freshness protection plastic packing bag is prepared from the following raw materials in parts by weight: 60-70 parts of polyethylene masterbatches, 10-15 parts of propylene-butene-1 random copolymer, 15-20 parts of pueraria starch, 5-8 parts of reed fibers, 6-12 parts of nano-bentonite, 1-3 parts of a radical initiator, 2-4 parts of propolis, 2-6 parts of phytic acid, 0.5-1 part of orange peel essential oil, 0.3-0.5 part of citronella oil, 0.3-0.5 parts of thyme essentialoil, 8-10 parts of chitosan, 5-7 parts of a pH regulator, 5-7 parts of tea polyphenols, 4-6 parts of graphene, 1-3 parts of a preservative and 1-3 parts of an epoxy silane coupling agent. The propolis, the phytic acid, the orange peel essential oil, the citronella oil, the thyme essential oil, the chitosan and the tea polyphenols are added in the raw materials, the food-grade antibacterial freshness protection plastic packing bag has an antibacterial property and anti-corrosion property, breeding of bacteria in the bag is inhibited effectively, corrosion is prevented, and freshness of food andusing safety can be ensured effectively.

Description

technical field [0001] The invention relates to the field of plastic packaging, in particular to a food-grade antibacterial and fresh-keeping plastic packaging bag. Background technique [0002] Plastic shopping bags are a necessity in daily life. As we all know, consumers and shopping malls have formed a rigid demand for plastic packaging bags, and this consumption has become a habit, and plastic packaging bags have been integrated into everyone's life. In daily life, plastic packaging bags are increasingly becoming the first choice for packaging products due to their light weight and ease of use. In developing countries, due to the process of commercialization, the number of shopping malls has increased steadily, which has led to the further prosperity of the plastic packaging bag industry, and the two show a high degree of correlation. The global plastic packaging bag industry generally shows a steady growth trend, especially the total demand for plastic packaging bags i...
