Abstract

The invention relates to the technical field of films, in particular to a food-grade polyvinyl chloride film and a calendaring process thereof. The food-grade polyvinyl chloride film is prepared from,by weight, 80-120 parts of PVC (polyvinyl chloride) resin, 20-60 parts of an environment-friendly plasticizer, 2-3 parts of an environment-friendly stabilizing agent, 1.5-2.5 parts of environment-friendly soybean oil, 0.020-0.028 part of environment-friendly toner, 3-7 parts of an environment-friendly bridging agent and 0.1-0.3 part of other additives. The food-grade polyvinyl chloride film is environmentally friendly, great in handfeel and visual effects and excellent in ultraviolet resistance and water resistance and has advantages of flame retardation, insulation, alkali and acid resistance, cold and mould proofing, corrosion resistance, static resistance, tensile resistance, aging resistance and the like, thereby being excellent in comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of films, in particular to a food-grade polyvinyl chloride film and a calendering process thereof. Background technique [0002] With the development of the PVC industry, the improvement of human living standards and the constant pursuit of material, it is widely used in the field of inflatable products, such as inflatable toys, PVC balloons, inflatable mattresses, and water inflatable products. The air-blown film has poor environmental protection, which limits its application in food and other fields. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a food-grade polyvinyl chloride film, which is environmentally friendly, has good hand feeling and visual effects, good anti-ultraviolet effect, and waterproof Good performance; also has the advantages of flame retardant insulation, alkali and acid res...
