Abstract

Provided is an improved toughening filling material for a plastic film. The filling material is prepared from the following raw materials, by weight, 16-25 parts of PVC particle material, 4-6 parts of composite stabilizing agent, 3-7 parts of foaming auxiliary agent, 1-4 parts of sodium bicarbonate, 23-35 parts of polyvinyl chloride, 15-18 parts of calcium carbonate, 20-24 parts of light magnesium oxide, 4-8 parts of kaolin, 3-4 parts of K12 foaming agent, 1.6-2.0 parts of release agent, 1.2-2.3 parts of calcium stearate, 2.4-3.2 parts of glycerin, 3-5 parts of polyethylene wax, 4-6 parts of hydrochloric acid, 2-4 parts of graphite, and 3-5 parts of ceramic fibers. The beneficial effects are that the toughening filling material raises intensity and heat resistance of a plastic film, especially the toughness is raised well, and mechanical properties of the plastic film are improved.

Description

Technical field [0001] The invention involves a improved plastic film. Background technique [0002] Plastic packaging and plastic packaging products occupy a large share in the market, especially the composite plastic soft packaging, which has been widely used in food, medicine, chemical industry and other fields. Among them, food packaging is the largest., Speed frozen food packaging, cooking food packaging, fast food food packaging, etc. These products have brought great convenience to people's lives.For plastic film, the surface of the plastic film can be high, wet, strong, strong, and good for tearing.However, the existing plastic fillers cannot meet the use of toughness well, causing the plastic film to tear.Therefore, the plastic film needs to enhance fillers to improve the performance of plastic film. Invention content [0003] In response to the lack of existing technology, the problem to solve the present invention is to provide a improved plastic film with tougher fil...
