Is transparent thermal label paper suitable for all types of surfaces?

Transparent thermal sensitive label paper is not entirely suitable for all types of surfaces, and its applicability mainly depends on the material properties of the label paper and the properties of the surface to be attached. The following is a detailed analysis of the applicability of transparent thermal sensitive label paper:

1、 Characteristics of transparent thermal label paper

Transparent thermal label paper has the characteristics of high transparency, easy printing and recognition. The printing principle is to use a thermal head to heat up, causing a chemical reaction on the thermal coating on the label paper, thereby displaying text or images. This type of label paper is usually used in situations where product information needs to be displayed or quick identification is required.

2、 Applicable surface types

Smooth surface: Transparent thermal label paper has good adhesion on a smooth surface and can be firmly attached to various smooth materials such as plastic, glass, metal, etc.

Semi rough surface: For some semi rough surfaces, transparent thermal label paper can also provide some adhesion, but it may need to be tested and adjusted according to specific surface conditions.

3、 Not applicable for surface type

Extremely rough surface: On extremely rough surfaces, the adhesion of transparent thermal sensitive label paper may be affected, resulting in the label not being firmly attached or easily falling off.

Porous or hygroscopic surfaces: Porous or hygroscopic surfaces may absorb adhesive components on label paper, leading to a decrease in viscosity. For example, surfaces such as wood and paper may not be suitable for using transparent thermal label paper.

Special chemical surfaces: Some special chemical surfaces may react with the adhesive components of transparent thermal label paper, leading to adhesive failure. Therefore, it is necessary to conduct sufficient testing on the surface to be pasted before use.

4、 Precautions for use

To ensure the adhesion effect of transparent thermal label paper on different surfaces, the following are some usage precautions:

Clean the surface: Before pasting the label, ensure that the surface to be pasted is clean, free of oil stains, dust, and other impurities.

Suitable temperature: During the pasting process, a suitable temperature should be maintained to avoid too low or too high a temperature affecting the adhesion of the label.

Apply pressure: When pasting labels, appropriate pressure should be applied to ensure that the air between the label and the surface being pasted is expelled, thereby improving the adhesion strength.

In summary, although transparent thermal label paper has a wide range of application scenarios, it is not entirely suitable for all types of surfaces. When selecting and using, it is necessary to consider and test comprehensively based on the properties of the surface to be pasted and the material characteristics of the label paper.
