Problems solved by technology

However, the current degradation products always have one or another deficiency
At present, it is more common to use petroleum-based plastic polyolefin materials as carriers to prepare degradable plastics, or to use polylactic acid polymers prepared from natural substances to improve the biodegradability of degradable plastics. However, the heat resistance of processed materials Insufficient performance, it is difficult to meet the requirements of shopping bags...

Abstract

The invention discloses a degradable environment-friendly shopping bag. The shopping bag is a T-shirt bag or a waistcoat bag, 25-35 microns in thickness, 30-50 cm in length, and 20-30 cm in width, the rim width of the bag is 10-16 cm, and the length of the handle of the bag is 12-16 cm. The shopping bag comprises the following ingredients in parts by weight: 100 parts of vegetable starch, 1-2 parts of stearic acid, 1.5-2.5 parts of calcium stearate, 1.5-2.5 parts of a titanate coupling agent, 4-6 parts of heavy calcium carbonate powder, 2-4 parts of liquid paraffin, 14-16 parts of ethylene-methyl acrylate copolymer, 15-17 parts of low density polyethylene, 6-8 parts of linear polyethylene, and 13-15 parts of high density polyethylene.
