The advantage of the glass material

October 15, 2021

The glass material has good barrier properties, which can effectively prevent oxygen and other gases from attacking the contents, and also prevent the volatile components of the contents from volatilizing into the atmosphere. At the same time, the glass bottle is safe and hygienic, has good corrosion resistance and acid corrosion resistance, and is suitable for packaging acidic substances. Therefore, at present, the packaging of Chinese liquor is still dominated by glass bottles. The appearance of glass wine bottles is colorless and transparent, and the color is monotonous, which limits the development of product packaging differentiation to a certain extent. In recent years, with the development of the national economy, people's material culture has become more abundant, and the demand for wine consumer packaging has been escalating. 

In order to meet people's demand for color consumption, glass wine bottle manufacturers have made great efforts, such as using labeling and baking flowers. , Spray glaze and other processes. Among them, roasting flowers and spraying glaze are the two main ways that manufacturers currently change the color of glass wine bottles. The baking process is divided into low temperature baking process and high temperature baking process according to the type of baking paper used. Correspondingly, decal paper is divided into low-temperature decal paper and high-temperature decal paper. The baking temperature of low-temperature decal paper is 160-200 ℃, and the baking temperature of high-temperature deco paper is 560-600 ℃. High/low temperature decal paper, also known as "water transfer decal paper", is a printing process that uses water pressure to hydrolyze the transfer paper with a color pattern, which is the process principle of indirect printing.
