How is the water resistance of self-adhesive coated paper?

The water resistance of self-adhesive coated paper mainly depends on many factors such as its material characteristics, manufacturing process and use environment. The following is a detailed analysis of its water resistance:

Water resistance Overview

Basic water resistance: self-adhesive coated paper in the case of slight contact with water, usually has a certain water resistance, will not immediately fall off or deformation. This feature makes it suitable for applications where basic waterproof functions are required.

Long soak: However, if soaked in water for a long time, the stickiness of the self-adhesive coated paper may be affected, causing the label to fall off or deform. This is because water may penetrate into the adhesive layer and destroy its viscous structure.

Influencing factor

1. Material quality: The quality of self-adhesive coated paper on the market is uneven, and high-quality products often have better water resistance. Therefore, when selecting self-adhesive coated paper, attention should be paid to its material composition and manufacturing process to ensure that it meets the needs of use.

2. Printing process: Some factors in the printing process, such as too much pressure, too fast speed, and too high temperature, may adversely affect the water resistance of self-adhesive coated paper. Therefore, the process parameters should be strictly controlled in the printing process to ensure that the water resistance of the self-adhesive coated paper is not damaged.

3. Use environment: The water resistance of self-adhesive coated paper is also affected by the use environment. For example, high temperature, humidity, acidic or alkaline environments may accelerate the aging process of self-adhesive coated paper and reduce its water resistance. Therefore, when using self-adhesive coated paper, you should try to avoid exposing it to the harsh environment.

Application suggestion

Short-term waterproof requirements: For short-term waterproof needs, self-adhesive coated paper can usually meet the requirements. However, care should be taken to avoid long-term immersion or contact with a large amount of water during use.

Long-term waterproof requirements: If you need long-term waterproof function, it is recommended to consider using other self-adhesive materials with better water resistance, such as PET self-adhesive labels.

In summary, self-adhesive coated paper has certain water resistance, but it may be affected in a long soak or harsh environment. Therefore, the selection and use need to be comprehensively considered according to specific needs and environmental conditions.
