Abstract

The invention relates to the technical field of packaging materials, in particular to a high-barrier antiskid packaging film and a preparation method thereof. The packaging film is composed of a CPE film, a PET film, a modified VMPET film and a PE film which are sequentially layered, the CPE film and the PE film are prepared in a three-layer co-extrusion forming mode, and one face of the VMPET film is reversely plated with an aluminum-plated layer formed by metal aluminum, so that the barrier property, the aluminum layer adhesive force and the corona value attenuation period are all obviously improved, and under the severe high-humidity and high-temperature conditions, the interface of the packaged PET / VMPET aluminum plating layer is not layered, so that the integrity of the package is ensured, and the contents are not deteriorated; the packaging material with the CPE (heat-resistant) / PET (polyethylene terephthalate) / modified VMPET / PE (low-temperature) composite structure has the characteristics of balanced internal and external structures, flat bag shape, soft buffering of the outer-layer CPE, puncture and falling resistance, high static friction and good stacking and transporting effect, the problems of stacking slipping and unsmooth transportation are solved, and the whole large package is high in tearing strength and puncture resistance, and can resist falling and impact bag breaking.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a high-barrier non-slip packaging film and a preparation method thereof. Background technique [0002] As people not only have higher and higher requirements for food health and taste quality, but also have higher and higher requirements for the quality, quality and safety of raw materials in food, so the bulk packaging of raw materials is becoming more and more strict. Large packaging should not only ensure the freshness and safety of food raw materials, but also withstand various external destructive forces during transit and transportation and be convenient to use. [0003] Most of the raw material packages on the market are woven bags, single-layer films (PE or PP) or composite films. During use, the quality of raw materials cannot be guaranteed (especially in harsh transportation environments, such as high humidity conditions, etc.), transportation process Damag...
