High-insulation low-static anti-wrinkle heat-seal type functional film

Abstract

The invention relates to a high-insulation low-static anti-wrinkle heat-seal type functional film which comprises the following components of PVC, stabilizing agent, H-16, AC316, MBS, oxidized polyethylene, silicon dioxide, ACR and epoxidized soybean oil, wherein PVC is polyvinyl chloride and poly aluminum hydrogen; the stabilizing agent is a common agent, in particular OM1; AC316 is tissuemat E; MBS is the terpolymer of methyl methacrylate (M), butadiene (B) and styrene (S); and ACR is acrylate copolymer. The components are fully mixed and then made into a film by using a blow molding machine. The high-insulation low-static anti-wrinkle heat-seal type functional film is prepared by the following steps of: fully mixing the components in proportion by weight and finally loading in the blow molding machine. The products produced by the technology has the advantages of no poison, high diaphaneity, bright surface, impact resistance, tear resistance, no combustion, no moisture absorption, and simple and firm heat seal, and is particularly suitable for meeting requirements of various high-speed automatic packaging machines.

Description

technical field [0001] The invention relates to a packaging film, in particular to a high-barrier, low-static anti-wrinkle heat-sealable functional film. Background technique [0002] At present, during the use of films, in order to achieve different effects of product packaging, the requirements for films are getting higher and higher, especially biaxially oriented polypropylene films (BOPP), which are widely used in outer film packaging such as tobacco. Wrinkles cannot be produced on the surface of the film in a long-term natural environment. The film produced by the existing film production process has poor chemical resistance and is easy to react with heavy-colored inks, especially bright red and green, to cause wrinkles. The other is the shrinkage rate. The surface of the small package is not compact, which affects the appearance of the product, and the high heat sealing temperature affects the packaging speed, and the barrier property is poor. As a result, the film is...

[0002] At present, during the use of films, in order to achieve different effects of product packaging, the requirements for films are getting higher and higher, especially biaxially oriented polypropylene films (BOPP), which are widely used in outer film packaging such as tobacco. Wrinkles cannot be produced on the surface of the film in a long-term natural environment. The film produced by the existing film production process has poor chemical resistance and is easy to react with heavy-colored inks, especially bright red and green, to cause wrinkles. The other is the shrinkage rate. The surface of the small package is not compact and affects the appearance of the product, the high heat sealing temperature affects the packaging speed, and the barrier property is poor

As a result, the film is always unsatisfactory when used
