Problems solved by technology

[0002] All kinds of goods are packaged, or in cartons, or in metal, or in plastic sheets, and many of them are made of film. Film packaging is mostly used for food and medicine. , it is easy to make the film stick to the materials outside the box, such as the carton, or the film becomes brittle due to the aging of the plastic, thus losing the ability to isolate moisture and air, and the durability of the packaging decreases, which is not conducive to the preservation of the contents

Embodiment 1

[0018] A film material, comprising a PET base layer with a roughness of 1.0-2.5nm, an LDPE layer covering the base layer in sequence, a blended layer of CPP and PA, and a BOPP layer coated on the blended layer, the thickness of the film material It is 0.01~0.05mm; the tensile modulus of the membrane material is 500-1300MPa. It is suitable for film packaging of most products and has good anti-exposure performance.

Embodiment 2

[0020] A film material, comprising a PET base layer with a roughness of 1.2-3.5nm, an ink layer covering the base layer, an LDPE layer, a blended layer of CPP and PA, and a BOPP layer coated on the blended layer, the film The thickness of the material is 0.01~0.05mm; the tensile modulus of the film material is 500-1300MPa, and the adhesion energy is 0.8-1.5mJ. While having good anti-exposure performance, it also has a more effective ability to isolate moisture and air.

Abstract

The invention relates to a film material. The film material includes a PET basal layer, LDPE layers which are sequentially arranged on the PET basal layer in a covering mode, a mixing layer of CPP andPA and a BOPP layer which is distributed on the mixing layer of CPP and PA in a coating mode, and the thickness of the film material is 0.01-0.05 mm. The film material is higher in a function of sunexposure protection, is not prone to bonding with other materials due to sun exposure or to being brittle due to aging, the packing durability is higher, and the capabilities of water isolation and air isolation are higher.

Description

technical field [0001] The invention relates to a film material. Background technique [0002] All kinds of goods are packaged, or in cartons, or in metal, or in plastic sheets, and many of them use films. Film packaging is mostly used for food and medicine, but for conventional films, it is difficult to withstand long-term outdoor exposure. , it is easy to make the film stick to the material outside the box, such as the carton, or the film becomes brittle due to the aging of the plastic, thus losing the ability to isolate moisture and air, and the durability of the packaging decreases, which is not conducive to the preservation of the contents. Contents of the invention [0003] The purpose of the present invention is to provide a film material, which has excellent resistance to sunlight exposure, is not easy to stick to other materials due to exposure to sunlight, or becomes brittle due to aging, has good packaging durability, and has excellent ability to isolate moistur...
