Abstract

The invention discloses a plastic bag with high thermal stability which is characterized by being prepared from the following raw materials in parts by weight: 75-125 parts of a main ingredient, 1-2 parts of di-(3,4-dimethyl benzylidene) sorbitol, 0.4-1 part of vinyl end silicone oil, 1-2 parts of zinc stearate, 0.1-0.6 part of microcrystalline wax, 0.4-0.9 part of cocoamidopropyl betaine, 4-8 parts of a filling reinforcing agent, 0.2-1 part of a silane coupling agent, 1-3 part of an antioxidant, and 1-3 part of a composite lubricant. The main ingredient comprises the following components in parts by weight: 60-100 parts of high density polyethylene, 12-20 parts of an ethylene-vinyl acetate copolymer, and 1-4 parts of an acrylonitrile-butadiene-styrene copolymer. The composite lubricant isprepared by adopting the following processes: mixing zinc stearate, oleamide and N,N-ethylene bis-stearamide, stirring at the room temperature, heating and continuously stirring, cooling, and grinding. The plastic bag with high thermal stability is high in toughness, and extremely excellent in tensile strength.

Description

technical field [0001] The invention relates to the technical field of plastic bags, in particular to a plastic bag with high thermal stability. Background technique [0002] Plastic bags are a common daily necessities for people nowadays.
