Abstract

The invention provides a matt coating with soft and smooth touch, which is obtained by rolling a coating liquid onto a film and drying it. The coating liquid comprises the following components in terms of mass percentage: water dispersible resin 10- 40%, dispersing solvent 60‑90%, antiblocking agent 0‑3%, defoamer 0‑0.2%, slip agent 0‑1%, leveling agent 0‑0.5%, adhesion promoter 0.4‑5%. The coating has good adhesion on the surface of PET, NY, BOPP and PE films, and can obtain excellent matte effect after full-plate coating or partial coating on the surface.

Description

technical field [0001] The invention relates to the technical field of packaging material encapsulation, in particular to a soft and smooth matte coating. Background technique [0002] In some packaging containers on the market, the use of various colorful flexible packaging can attract consumers' attention. And some packaging containers with matte effect on the surface give people a simple and elegant feeling. [0003] In flexible packaging, plastic films with a matte surface are used for packaging bags with a matte surface, such as matte BOPP and matte PET films. The surface matting or matte effect of these films is derived from the formation of incompatible polymer particles or inorganic particles uniformly dispersed on the surface. Due to the poor compatibility of the dispersed particles, there will be problems of poor transparency, rough hand feeling and high surface hardness. In addition, the factors of the production process determine that these films are often pro...
