Self-adhesive coated paper is not applicable in which chemical environments?

Self-adhesive coated paper may not be suitable in specific chemical environments, which is mainly related to the chemical stability of its substrate (coated paper) and adhesive. The following are some chemical environments that may cause self-adhesive coated paper to be unsuitable:

1.Strong acid and alkali environment:

Strong acids and alkalis are extremely corrosive and can destroy the fiber structure of the paper and the stability of the adhesive, resulting in the loss or deformation of the sticker label. Therefore, in the presence of strong acid and alkali chemical environment, self-adhesive coated paper may not be suitable.

2.Organic solvent environment:

Some organic solvents, such as alcohol and acetone, can dissolve or destroy the adhesive, causing the label to lose viscosity. Although the coated paper itself has relatively good resistance to organic solvents, the damage of the adhesive will directly affect the use of the adhesive. Therefore, in an environment with a high organic solvent content, the use of self-adhesive coated paper needs to be cautious.

3.High humidity environment:

Although high humidity does not directly constitute chemical corrosion, in a long-term high humidity environment, the adhesive of the self-adhesive coated paper may reduce the viscosity due to moisture absorption, and even cause the label to fall off. In addition, humidity changes may also cause the expansion and contraction of the paper, affecting the flatness and readability of the label.

4.Extreme temperature environments:

Although coated paper and common self-adhesive adhesives have certain temperature resistance, their performance may be affected in extreme high or low temperature environments. For example, high temperatures may cause the adhesive to soften and increase fluidity, while low temperatures may cause the adhesive to harden and lose viscosity. Therefore, in extreme temperature environments, the use of self-adhesive coated paper may not be good.

5.Oxidizing environment:

Some strong oxidants can destroy the fiber structure of the paper and the chemical composition of the adhesive, resulting in damage to the self-adhesive label. While this is relatively rare, it is still something to be aware of in specific industrial or laboratory Settings.

In summary, self-adhesive coated paper may not be suitable in chemical environments such as strong acids and alkalis, high organic solvent content, high humidity, extreme temperatures and strong oxidants. When selecting a self-adhesive label, consider it based on specific application scenarios and environmental conditions to ensure label stability and reliability. For the application needs of special environments, you can consult self-adhesive label suppliers or relevant experts to obtain more professional advice.
