High strength anti-microbial packaging bag

Abstract

The invention relates to a high strength anti-microbial packaging bag, which belongs to the field of packaging bag technology. According to the invention, the packaging bag is prepared by the following raw materials by weight with melt blending, extrusion and film blowing steps: 100 parts of polypropylene resin, 3-7 parts of polyvinyl alcohol, 1-3 parts of bamboo fiber, 20-40 parts of starch, 0.2-1.5 parts of nanometer titanium dioxide, 0.02-0.7 parts of anti-oxidant, 15-30 parts of calcium carbonate, 5-10 parts of paraffin, 0.1-1 parts of silane coupling agent and 2-5 parts of epoxy soybean oil. The intensity of the packaging bag is increased by adding bamboo fiber; and the added bamboo fiber and titanium dioxide have antibacterial property, and the packaging bag has excellent antibacterial property; degradable polyvinyl alcohol and starch are added for degrading products and eliminating environment pollution, thereby not only reducing packaging bag cost, but also minimizing environment pollution with environmental protection.
