Self-adhesive materials are composed of three parts: base material, glue, and backing paper. The right materials are very important.

1. Adhesives are permanent or removable

Based on the main performance characteristics of adhesives, they can be divided into two categories: permanent adhesives and removable adhesives.

2. Pay attention to the actual meaning of the label surface

Because labels made of self-adhesive materials are likely to be labeled on the surface of various materials, such as glass, metal, cardboard, and plastic, etc. Plastic can be further divided into: polyethylene and high-density high-pressure polyethylene. Tests have shown that different label surfaces have a greater impact on performance.

3. Surface structure of label material

To put it bluntly, if you want the labeling part to be smooth, you need stronger glue with stronger viscosity.

4. The surface appearance of the label board

The surface of the labeling board can be divided into a flat surface and an inclined surface. If the labeling surface has a certain slope (for example, the surface of a medicine bottle with a diameter of less than three centimeters), it is likely to require facial tissue with good adhesion or extremely viscous tissue. Super glue.

5. Cleaning of label surface

Self-adhesive materials are most suitable for sticking to label boards with clean, dry surfaces and no oil stains and dust.

6． Negative impact of plastic deformation on glue

Labeling standards - The viscosity of self-adhesive labels must be adhered under cold, hot, humid or indoor temperature standards.

7． Application environment - whether the self-adhesive label paper is exposed to an environment below freezing, whether it is used outdoors, high temperature, humidity or light with ultraviolet light, and whether it is close to a hot engine.
