Problems solved by technology

[0002] When the existing plastic film is made into a packaging bag to package the product, an easy-tear opening is generally arranged on one side of the packaging bag by mechanical equipment, and the user opens the packaging bag through the easy-tear opening, but due to the easy-tear opening The tear line and the packaging bag are less firm than other parts of the packaging bag. When the product is stored and transported, the easy-to-tear line is easy to come off, resulting in leakage of the product in the packaging bag, resulting in product damage. waste, reduce economic efficiency

Abstract

The invention relates to an easily peelable film, which is prepared from the following raw materials by weight: 11-15 parts of polyvinyl chloride, 11-14 parts of porous fibre, 2-4 parts of a heat stabilizer, 8-10 parts of linear low density polyethylene, 5-7 parts of sodium silicate, 6-9 parts of polyethylene glycol, 3-6 parts of a phosphate stabilizer, 1-4 parts of a lubricating agent, 4-7 parts of sodium hydroxide, 1-1.5 parts of potassium silicate, 16-18 parts of an ethylene-vinyl acetate copolymer, 9-17 parts of homo-polypropylene, 2-4 parts of phosphate, 8-12 parts of n-butyl acetate, and 5-8 parts of water-based acrylic resin. The easily peelable film provided by the invention has good linear tearing property, uniform tearing port strength and density, and wide application.

Description

technical field [0001] The invention relates to an easy-peelable film. Background technique [0002] When the existing plastic film is made into a packaging bag to package the product, an easy-tear opening is generally arranged on one side of the packaging bag by mechanical equipment, and the user opens the packaging bag through the easy-tear opening, but due to the easy-tear opening The tear line and the packaging bag are less firm than other parts of the packaging bag. When the product is stored and transported, the easy-to-tear line is easy to come off, resulting in leakage of the product in the packaging bag, resulting in product damage. Waste and reduce economic benefits. Easy-to-open film is mainly used in the packaging of related snack foods such as after-dinner snacks. It is a type of functional packaging material developed to meet the requirements of convenient use. The easy-opening film not only requires the film to have a low tear strength, but also requires a r...
