Problems solved by technology

[0002] The existing films for container bags have poor overall impact resistance, insufficient toughness, and unsatisfactory sealing and barrier properties
There is an aluminum film layer in some film structures, but during use, the aluminum film layer is prone to creases or breaks due to external forces, which greatly affects its barrier performance, thereby reducing the overall service life
Moreover, the general container bag film has no anti-ultraviolet function, which does not meet the actual use requirements

Abstract

The invention relates to an uvioresistant impact resistant composite type flexible freight bag film, wherein the uvioresistant impact resistant composite type flexible freight bag film comprises a PET outer film layer, a first adhesion layer, a first connection film layer, an ultraviolet absorption layer, a second connection film layer, a second adhesion layer, a PET inner film layer, an aluminum coating layer and a PE film layer which are sequentially connected, the aluminum coating layer is coated on one side of the PET inner film layer, and the thickness ratio of the PET outer film layer to the first adhesion layer to the first connection film layer to the ultraviolet absorption layer to the second connection film layer to the second adhesion layer to the PET inner film layer to the aluminum coating layer to the PE film layer is 1:(4-6):(0.8-1.8):(0.8-1.8):(0.8-1.8):(4-6):(0.8-1.2):(7-8):(0.5-1.5). The uvioresistant impact resistant composite type flexible freight bag film is good in impact resistance property, high in seal and barrier properties and good in toughness, and resists ultraviolet.

Description

technical field [0001] The invention relates to a film, in particular to a container bag film. Background technique [0002] The existing films for container bags have poor overall impact resistance, insufficient toughness, and unsatisfactory sealing and barrier properties. There is an aluminum film layer in some film structures, but during use, the aluminum film layer is prone to creases or breaks due to external forces, which greatly affects its barrier performance, thereby reducing the overall service life. Moreover, the general container bag film has no anti-ultraviolet function, which does not meet the actual use requirements. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to overcome the deficiencies in the prior art and provide a composite container bag film with good impact resistance, UV resistance, high sealing and high barrier, and good toughness. [0004] Technical solution: In order to solve the above technical p...
