Manufacturing method of blackening-free aluminized paper after labeling for beer bottles

Abstract

The invention discloses a manufacturing method of blackening-free aluminized paper after labeling for beer bottles, which specifically comprises the following steps: S1, feeding raw paper into a coating machine, and carrying out bottom coating treatment on the surface of the raw paper by using acidic bottom coating glue through the coating machine to form a bottom coating on the surface of the rawpaper, S2, feeding the base paper subjected to the base coating treatment in the step S1 into a vacuum aluminizing machine, heating, melting and gasifying aluminum by the vacuum aluminizing machine to perform vacuum aluminizing treatment on the base paper, and forming an aluminizing layer on the front surface of the base paper, S3, feeding the raw paper subjected to aluminizing treatment in the step S2 into a coating machine, so that a surface coating is formed on the front face of the raw paper, and S4, carrying out rewetting treatment on the aluminized paper formed after surface coating treatment again. When the aluminized paper disclosed by the invention is in contact with alkaline glue, the blackening phenomenon can be well inhibited, and meanwhile, customers do not need to replace the glue, so that the market competitiveness of products can be improved.

Description

technical field [0001] The invention relates to the field of labels and packaging, in particular to a method for making aluminum-plated paper that does not turn black after beer labels are pasted on bottles. Background technique [0002] Nowadays, China's printing market has become saturated, and products have developed from simplification to diversification. If enterprises do not have diversified products, they will not be able to follow the aesthetics of consumers and fail to meet customer satisfaction. In this case, Chinese printing enterprises must follow the three survival principles of environmental protection responsibility, cost saving and quality first if they want to gain a foothold and develop. In the colorful printing industry, there are still a certain number of manufacturers using traditional crafts, but most of the traditional printing methods are time-consuming, labor-intensive, expensive, and sometimes fail to meet user satisfaction and government environmen...

Problems solved by technology

In the colorful printing industry, there are still a certain number of manufacturers using traditional crafts, but most of the traditional printing methods are time-consuming, labor-intensive, expensive, and sometimes fail to meet user satisfaction and government environmental protection requirements. At the same time, customers have higher and higher requirements for product quality. In order to save their own costs, some customers have to use low-cost raw materials, such as glue for beer labels. The phenomenon of blackening seems to be moldy. If such a product appears in the market, it will definitely not work
