Abstract

A glassine coating material is prepared from, by total coating formulation weight, 3-5% of at least one or two pigments different in molecular weight, 1-2% of at least one type of acrylic resin, 2-4% of at least one type of polyvinyl alcohol, 1-3% of at least one type of latex, 0.1-0.3% of at least one functional additive, 0.01-0.03% of at least one viscosity modifier and the balance water. After addition of the viscosity modifier, coating viscosity is controlled within a range of 500-600mPa.S. Glassine which adopts the glassine coating material has advantages of freeness of repellence to silicon oil coating, uniformity in silicon oil coating, low consumption and the like.

Description

technical field [0001] The invention relates to a coating ingredient for glassine paper, which belongs to the technical field of surface coating. Background technique [0002] Glassine paper is widely used in product packaging, labeling and other industries. Glassine paper has good internal strength and transparency, and has the functions of high temperature resistance, moisture resistance, and oil resistance. It is generally used for product packaging in food, pharmaceutical and other industries, as a special adhesive tape for high-speed automatic labeling (especially for high-speed labeling) , Double-sided tape substrate trademark, laser anti-counterfeiting label and other release applications. The general typical use of glassine paper is the bottom paper of self-adhesive label paper. As one of the label substrates, it needs to go through multiple processes in the middle, and finally it is processed into label paper together with other auxiliary materials. Silicone oil c...
