Problems solved by technology

[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 in the existing film production process has poor chemical resistance and is easy to react with heavy-color inks, especially bright red and green, to cause wrinkles; the shrinkage rate is small. Compactness affects the appearance of the product; high heat sealing temperature affects its packaging speed and poor barrier properties

Abstract

The invention provides an environment-friendly anti-crease shrink package film, and relates to a package film. The environment-friendly anti-crease shrink package film is characterized by comprising the following components by weight: 100KG of thermoplastic starch (TPS), 350KG of LLDPE (Linear Low Density Polyethylene), 1.9KG of stabilizer, 2KG of pentaerythritol mixed aliphatic ester, 3KG of methyl methacrylate-butadiene-styrene copolymer, 0.01KG of silicon dioxide, 0.6KG of methyl methacrylate and 1KG of epoxidized soybean oil. The environment-friendly anti-crease shrink package film has the beneficial effects that the product produced by the process is toxic, highly transparent, bright in surface, impact-resistant, tear-resistant, non-combustible, nonhygroscopic, and easy and firm for hot sealing, and thus especially capable of meeting the requirements of various high-speed automatic packaging machines. As a result, the environment-friendly anti-crease shrink package film can be widely applied to the cigarette industry and the printing industry, and to the packages of medicine, audiovisual products and various boxed products, and is capable of achieving the effects of moisture protection and dust prevention.

Description

Technical field: [0001] The invention relates to a packaging film, in particular to an environment-friendly anti-wrinkle shrink packaging 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 in the existing film production process has poor chemical resistance and is easy to react with heavy-color inks, especially bright red and green, to cause wrinkles; the shrinkage rate is small. Compactness affects the appearance of the product; high heat-sealing temperature affects its packaging speed, and its barrier property is poor. Invention content: [0003] The technical problem solved by the present invention is to ...
