Description

High wear-resisting type polypropylene cigarette membrane

Technical Field

The utility model belongs to the technical field of the cigarette membrane, especially, relate to a high wear-resisting type polypropylene cigarette membrane.

Background

The cigarette film is a high-grade BOPP film, and has the advantages of low heat sealing temperature, better barrier property, high transparency, thickness uniformity, excellent heat shrinkage and the like compared with the common packaging film.

The friction (the friction is mostly the friction between the strip packs and the box body, especially the friction is stained with dust in the display process, and the dust can increase the degree of frosting) caused by boxing (or boxing), transportation and distribution of the outer packaging surfaces of the existing cigarette strip packs and small bags forms a white powder appearance, the distribution position of the white powder appearance is not fixed, the white powder appearance is generally called as the phenomenon of frosting, the phenomenon is particularly obvious on dark box skins, the surface of a cigarette film is scratched, the haze is increased, and the attractiveness of the strip packs is seriously influenced.

At present, the improvement of the wear resistance of the cigarette film is researched on a biaxial stretching process and a raw material additive, but most of the cigarette film is difficult to consider the optical performance and the friction performance, the wear resistance of the existing cigarette film mostly stays on the packaging, protection and transportation of cigarette film products, the wear resistance improvement effect on the computer using process is poor, and the problem that how to improve the wear resistance from the material of the cigarette film needs to be solved by workers in the field is solved.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a high wear-resisting type polypropylene cigarette membrane, through the interpolation of thin layer particle layer and wearing layer, thin layer particle layer plays anti-stick and smooth effect, and the wearing layer possesses the characteristics that self-lubricating and frictional force are low, on the basis that does not reduce other performances of cigarette membrane, has realized the promotion of wearability, has improved cigarette membrane comprehensive quality.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme:

the utility model relates to a high wear-resistant polypropylene cigarette film, which comprises a core layer, an upper surface layer and a lower surface layer, wherein the structural characteristics of the lower surface layer are consistent with and opposite to those of the upper surface layer and are arranged on the upper surface and the lower surface of the core layer;

the upper surface layer comprises a heat sealing layer, and the heat sealing layer is arranged on the upper surface of the core layer;

a thin particle layer is arranged on the upper surface of the heat sealing layer, and particles in the thin particle layer are anti-sticking particles;
