A kind of packaging material and its manufacturing process

Abstract

The invention provides a packaging material and a manufacturing technology thereof and relates to the field of materials. The material comprises a basic layer, the inner surface layer of the basic layer is coated with a pottery clay layer, and a printing layer is arranged on the side, far away from the pottery clay layer, of the basic layer. By coating the inner side of the basic layer with the pottery clay layer, the packaging material has good mildew-proof and damp-proof effects, and a catalytic function is achieved on a packaged object. The novel packaging material is environmentally friendly and beneficial to health.

Description

technical field [0001] The invention relates to the field of materials, in particular to a packaging material and a manufacturing process thereof. Background technique [0002] Packaging materials are widely used in various fields of industry. The performance of packaging materials directly affects the quality of packaged items. For example, whether the packaging materials have functions such as moisture release, mildew resistance, and freshness preservation directly determine the quality of the items in the package. The shelf life of the item, the freshness period, whether the physical properties will be affected, etc. [0003] At present, according to different fields of use, most of the packaging materials will also undergo corresponding technical treatment, such as setting an isolation layer, a sterilization layer, etc. on the inner layer of the packaging material, although these measures can play a certain role to a certain extent, But at the same time, it brings the p...

AI Technical Summary

Problems solved by technology

[0003] At present, according to different fields of use, most of the packaging materials will also undergo corresponding technical treatment, such as setting an isolation layer, a sterilization layer, etc. on the inner layer of the packaging material, although these measures can play a certain role to a certain extent, But at the same time, it brings about the problem of environmental pollution. For example, the aluminum foil paper in the inner layer of many packaging materials is not easy to decompose when discarded.
