High-performance CPP film and preparation process thereof

Abstract

The invention discloses a high-performance CPP film and a preparation process thereof, and relates to the technical field of CPP films, the high-performance CPP film comprises a CPP film, the surface of the CPP film is provided with a film winding roller, the CPP film comprises a CPP film body, the surface of the CPP film body is fixedly connected with a glass fiber film, the surface of the glass fiber film is fixedly connected with an aramid fiber film, and the surface of the aramid fiber film is fixedly connected with a film winding roller. The surface of the aramid fiber membrane is fixedly connected with a wear-resistant coating. Through cooperation of the CPP film body, the wear-resistant coating and the self-adhesive protective film, the CPP film body can be protected in the transportation process through the arrangement of the self-adhesive protective film, meanwhile, the wear-resistant coating is coated to improve the wear-resistant coefficient of the CPP film body, and the problems that the CPP film is often used as a product package, the wear-resistant coefficient of a traditional CPP film is low, and the service life of the CPP film is prolonged are solved. The problem that the service life of the CPP film may be directly affected due to the fact that the CPP film cannot be protected in the transportation process is solved, and the effect of prolonging the service life of the CPP film is achieved.

Description

technical field [0001] The invention relates to the technical field of CPP films, in particular to a high-performance CPP film and a preparation process thereof. Background technique [0002] Cast film is a kind of non-stretched, non-directional flat extrusion film produced by melt casting and quenching. There are two ways of single-layer casting and multi-layer co-extruding casting. Fast, high output, excellent film transparency, gloss, thickness uniformity, etc. At the same time, because it is a web-extruded film follow-up process, such as printing, compounding, etc. are very convenient, so it is widely used in food, medical supplies, textiles , flowers, daily necessities packaging. [0003] There are following problems at prior art: [0004] 1. Because CPP film is often used as product packaging, the traditional CPP film has a low wear resistance coefficient, which is easy to cause damage. At the same time, the CPP film cannot be protected during transportation, which m...

AI Technical Summary

Problems solved by technology

[0007] The present invention provides a high-performance CPP film and its preparation process. One purpose is to have the effect of improving the service life of the CPP film, and solve the problem that the traditional CPP film has a low wear resistance because the CPP film is often used as product packaging. , so it is easy to cause damage, and at the same time, the CPP film cannot be protected during transportation, which may directly affect the service life of the CPP film; another purpose is to solve the problem that the traditional CPP film lacks testing links in the production process and cannot A number of tests are carried out on the CPP film, and it is impossible to accurately grasp the product quality after the completion of the CPP film production. The outflow of poor-quality CPP film may cause certain economic losses, so as to achieve the effect of controlling the product outflow; the other The purpose is to solve the problem that the raw materials need to be crushed by a crushing device. After the traditional crushing device is crushed, some raw materials will be assisted on the inner wall surface of the crushing box. This part of the raw materials is difficult to flow out, which will easily cause unnecessary waste of raw materials. In order to achieve the effect of improving the utilization rate of raw materials
