Abstract

The invention relates to the technical field of films, in particular to a fireproof packaging film. The fireproof packaging film is prepared from components in parts by mass as follows: 35-60 parts ofmetallocene linear low-density polyethylene, 4.5-7.5 parts of oxidized polyethylene wax, 2-6 parts of white master batch, 2-7 parts of polybutylene terephthalate, 3-8 parts of glass fiber, 2-5 partsof 2-hydroxypropyl-beta-cyclodextrin, 2-5 parts of hydroxypropyl acrylate, 4-6 parts of methacrylate, 0.3-0.5 parts of titanium dioxide, 2.1-3.8 parts of calcium carbonate powder, 7-9 parts of bentonite, 3-4 parts of a coupling agent, 4-8 parts of a flame retardant, 1-3 parts of a curing agent, 11-18 parts of tartrate, 1-3 parts of a compatilizer and 0.1-0.5 parts of lithium amide. According to the fireproof packaging film, the plastic film has flame retardance, original mechanical performance of the plastic film is kept, the use safety in building, aerospace and traffic industries and in lifesuch as the packaging material is guaranteed, and adverse conditions are prevented.

Description

Technical field [0001] The invention relates to the technical field of films, in particular to a fire-resistant packaging film. Background technique [0002] Flexible packaging refers to packaging in which the shape of the container can change after filling or taking out the contents. Plastic film is a kind of flexible packaging. Generally, sheet plastics with a thickness of less than 0.25mm are called films. The plastic film is transparent, flexible, has good water resistance, moisture resistance and gas barrier properties, good mechanical strength, stable chemical properties, grease resistance, easy to print beautiful graphics, and can be heat-sealed to make bags. The existing plastic film has poor flame-retardant properties, easily burns when catching fire, and is not safe. Summary of the invention [0003] The purpose of the present invention is to provide a fire-resistant packaging film that is safe to use and has good flame-retardant effects. [0004] To solve the above tec...
