What is the water resistance of copperplate adhesive labels?

The water resistance of copperplate adhesive labels is relatively limited. The following is a specific analysis of its water resistance:

1、 Overview of water resistance

Copperplate paper itself is not waterproof, so copperplate adhesive labels are prone to absorbing water and may be damaged in humid or high humidity environments. In the case of slight contact with moisture, copperplate adhesive labels may have certain water resistance and will not immediately peel off or deform. However, under prolonged immersion in water, the label may lose its viscosity and flatness, thereby affecting its effectiveness.

2、 Factors affecting water resistance

Material itself: The waterproof performance of copperplate adhesive label materials on the market varies greatly. Choosing high-quality copperplate adhesive materials plays an important role in ensuring their waterproof performance.

Printing process: Factors such as excessive pressure, fast speed, and high temperature during the printing process may affect the waterproof performance of copperplate adhesive labels, causing the material to lose its waterproof function.

Usage environment: Environmental factors such as high temperature, humidity, acidity, alkalinity, etc. may also cause copperplate adhesive labels to lose their waterproof performance.

3、 Methods to improve water resistance

Choose materials with good waterproof performance: When designing and making copperplate adhesive labels, you can choose adhesive materials with stronger waterproof performance, such as PVC adhesive.

Optimizing printing process: By adjusting parameters such as pressure, speed, and temperature during the printing process, the waterproof performance of copperplate adhesive labels can be optimized.

Film coating treatment: Covering the surface of copperplate adhesive labels with a layer of transparent plastic film can enhance the waterproof, oil resistant, wear-resistant and other properties of the labels.

4、 Suggested application scenarios

Considering the relatively limited water resistance of copperplate adhesive labels, it is recommended to avoid using them in situations that require long-term exposure to moisture or humid environments. For labels that require high waterproof performance, other materials or processes can be considered for production.

In summary, the water resistance of copperplate adhesive labels is relatively limited and is influenced by various factors. When selecting and using, it is necessary to consider comprehensively based on specific application scenarios and requirements.
