Embodiment 1

[0008] A fracture-resistant composite packaging material, the fracture-resistant composite packaging material has four layers, the first layer is a polyvinylidene chloride film 1 with a thickness of 30 microns, the second layer is a nylon film 2 with a thickness of 80 microns, and the third layer It is a dicyclopentadiene film 3 with a thickness of 55 microns, and the fourth layer is a cellulose acetate film 4 with a thickness of 90 microns. The composite packaging material is extruded and composited by four extruders to obtain a composite packaging material that is resistant to fracture. Add a portion of acrylic acetate between each layer of composite film.

Embodiment 2

[0010] A fracture-resistant composite packaging material, the fracture-resistant composite packaging material has four layers, the first layer is a polyvinylidene chloride film 1 with a thickness of 45 microns, the second layer is a nylon film 2 with a thickness of 60 microns, and the third layer It is a dicyclopentadiene film 3 with a thickness of 65 microns, and the fourth layer is a cellulose acetate film 4 with a thickness of 50 microns. The composite packaging material is extruded and composited by four extruders to obtain a composite packaging material that is resistant to fracture. Add a portion of acrylic acetate between each layer of composite film.

Embodiment 3

[0012] A fracture-resistant composite packaging material, the fracture-resistant composite packaging material has four layers, the first layer is a polyvinylidene chloride film 1 with a thickness of 60 microns, the second layer is a nylon film 2 with a thickness of 50 microns, and the third layer It is a dicyclopentadiene film 3 with a thickness of 75 microns, and the fourth layer is a cellulose acetate film 4 with a thickness of 40 microns.

Abstract

The invention discloses an anti-fracture composite packaging material. The anti-fracture composite packaging material has four layers, the first layer is a polyvinylidene chloride film of 30 microns to 60 microns in thickness, the second layer is a nylon film of 50 microns to 80 microns in thickness, the third layer is a dicyclopentadiene film of 55 microns to 75 microns in thickness, and the fourth layer is a cellulose acetate film of 40 microns to 90 microns in thickness. The composite packaging material has good anti-fracture property and the fracture strength of 36 Mpa to 39 Mpa.

Description

technical field [0001] The invention relates to a composite packaging material, in particular to a fracture-resistant composite packaging material. Background technique [0002] There are many types of packaging materials, including cardboard packaging materials, metal packaging materials, plastic packaging materials, etc. Among them, plastic packaging materials have the most application fields and have a very large market share. The performance of plastic packaging materials can be reflected by many performance indicators, among which the breaking strength is a key parameter. If the breaking strength is too low, when the plastic packaging material is subjected to a breaking impact, it will be more prone to breakage. After the packaging material is broken, the inside of the packaged material will be exposed to the outside, which will affect the use of the product. Therefore, the development of high breaking strength Plastic packaging is very necessary. Contents of the in...
