Biodegradable packaging material based on nano technology

Abstract

The invention discloses a biodegradable packaging material based on nano technology, and belongs to the field of packaging materials. The material comprises, by weight, the following components: 20-35parts of a degradable raw material, 10-15 parts of a nano raw material, 6-12 parts of a solubilizer, 2-7 parts of a coupling agent, 4-10 parts of an antioxidant and 3-7 parts of a plasticizer. The degradable raw material comprises, by weight, the following components: 15-18 parts of urethane vinyl ester resin, 8-11 parts of polyethylene glycol, 5-9 parts of modified starch, 20-40 parts of polyethylene terephthalate and 8-12 parts of polylactic acid. The packaging material is more scientific and reasonable, the toughness of the packaging material can be improved, the color of the packaging material can be changed during production, and the packaging material can be rapidly and completely decomposed through the action of microorganisms in the nature, so that the environmental burden is greatly reduced, the optimization of the environment is effectively promoted, the production cost is reduced, and a common packaging material can be replaced.

Description
