Abstract

The invention discloses a green and environment-friendly packaging material. The material comprises the following raw materials by weight: 40-50 parts of corn starch, 20-35 parts of persimmon peel powder, 6-10 parts of fulvic acid, 10-15 parts of pea protein, 10-20 parts of linear low density polyethylene, 5-8 parts of polylactic acid, 10-15 parts of crab shell powder, 4-8 parts of ginger powder,4-9 parts of nano titanium dioxide, 2-5 parts of sodium alginate, 0.1-3 parts of anthocyanin, 2-6 parts of sodium glutamate, 2-5 parts of beta-carotene, and 1-6 parts of beta-cyclodextrin. The packaging material provided by the invention has the advantages of safe and environment-friendly raw materials, degradability, good mechanical properties and good antibacterial properties, and is very suitable for food packaging.

Description

technical field [0001] The invention relates to a packaging material, in particular to a green and environment-friendly packaging material and a preparation method thereof. Background technique [0002] Food packaging materials are widely used. Food-grade packaging materials will be attached to the surface of some cooked foods. Packaging materials composed of chemically synthesized polymer materials have certain limitations in food packaging. Packaging prepared by chemical synthesis methods The material has limited use as it is not edible grade. And with the continuous improvement of people's living standards, the awareness of environmental protection of packaging materials is getting stronger and stronger. At present, food packaging materials use polystyrene and other plastics as base materials. Because it is difficult to decompose in the natural environment, it will become waste accumulation after use and become one of the main pollution sources of urban production and li...
