Preparation process of packaging material

Abstract

The invention relates to a preparation process of a packaging material and relates to preparation of a material. The preparation process specifically comprises steps as follows: (1) preparation of rawmaterials: Indonesia vesuvianite, purple sands, selenium soil, red sand from the Jinsha River, Shandong black pottery, Taiwan pottery clay and Guangdong Zijin sand are subjected to impurity removal and prepared for later use; (2) firing: firing is performed in a pottery kiln; (3) cooling and drawing of the kiln; (4) preparation: the fired raw materials are pound into 600-mesh powder; (5) mixing:all raw material powder is mixed in proportion; (6) blending: resin varnish is added to the well-blended pottery clay powder to be blended; (7) the well-blended pottery slurry is applied to packagingpaper in a back coating manner to be naturally cooled. The preparation process of a pottery-plated lining of the packaging paper replaces conventional packaging paper adopting aluminum foil and has very positive significance in environmental protection. Besides, the packaging paper has good mildew-proof, moisture-proof and fresh keeping efficacy.

Description

technical field [0001] The invention relates to the field of materials, in particular to a manufacturing process of packaging materials. Background technique [0002] At present, environmental pollution is becoming more and more serious, and environmental protection issues are imminent. According to different fields of use, most of the materials will also undergo corresponding technical treatment, such as setting an isolation layer and a sterilization layer 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 bring The problem of environmental pollution has come, such as the aluminum foil paper in the inner layer of many packaging materials, which is not easy to decompose when discarded. [0003] The research and development of environment-friendly new materials only solves the root of such problems. The present invention proposes an environment-friendly ceramic slurry to reduce environmental...
