Embodiment 1

[0013] A method for producing a high-barrier composite foam film, characterized in that: the composite foam film is made of PET 12 、PE 147 、PET 12 、AL 12 、PE 45 composition,

[0014] The PE 45 is a polyethylene film layer, the PE 147 It is a foamed polyethylene film layer,

[0015] The composite packaging film is completed through the following steps:

[0016] (1) PET 12 with PE 147 Pre-laminated; PET 12 Material and PE 147 Each material is dried in a drying room at 50°C-60°C for 24 hours, PET 12 with PE 147 After adding organic glue, dry in a drying room at 50°C-63°C for 24 hours,

[0017] (2) PET 12 with AL 12 Pre-compound; PET 12 Material and PE 147 Each material is dried in a drying room at 50°C-60°C for 22 hours, PET 12 with PE 147 After adding organic glue, dry in a drying room at 55°C-60°C for 24 hours,

[0018] (3) PET 12 / AL 20 Composite material and PE 45 Pre-compound; PET 12 / AL 20 The composite material is dried in a drying room at 40°C-60°...

Abstract

The invention discloses a production method of a high-barrier composite foam film, which is characterized in that the composite foam film is composed of PET12 / PE147 / PE45 / PET12 / AL20 / PE45. Through: (1) PET12 and PE147 pre-compound; (2) PET12 and AL12 pre-composite; (3) PET12 / AL20 composite material and PE45 pre-compound; (4) PET12 and PE147 composite material and PET12 / AL20 / PE45 composite material composite ; (5) Cutting into bundles is completed in five steps. Beneficial effects: the PE easy-tear type high-barrier composite foaming film of the present invention improves the strength of the film body itself, and overcomes the defects of poor ductility, easy tearing, and easy breakage when folded and other defects of traditional products. The hardness of the membrane body is further improved, and it also has the performance of adapting to environmental conditions such as external temperature and humidity.

Description

technical field [0001] The invention relates to a high-barrier composite packaging film, in particular to a production method of a high-barrier composite foam film. Background technique [0002] A few days ago, the transparency, gloss, mechanical strength, scalability, wear resistance, cold resistance and surface strength of the existing PE composite foam films on the market are not ideal. Furthermore, the aluminum foil layer is currently the only metal foil in the composite foam film packaging material, and its barrier protection properties such as water blocking, gas blocking, and light shading are unmatched by other packaging materials. However, general aluminum foil has poor ductility, very low thickness, is easy to break when folded, and has a relatively heavy weight per unit area, so it is prone to defects in its own performance such as holes, resulting in unsatisfactory barrier protection performance. Contents of the invention [0003] The purpose of the present in...
