How is the waterproof performance of self-adhesive copperplate label paper?

The waterproof performance of self-adhesive copper plate label paper is an important aspect of user concern, but the specific performance needs to be evaluated according to the specific application scenario and the production process of the label.

In general, the self-adhesive copperplate label paper itself does not have strong waterproof performance. This is because coated paper as a substrate, its water resistance mainly depends on the fiber structure and surface coating of the paper, and the surface treatment of ordinary coated paper is not enough to provide long-term waterproof protection. However, through some special processes, such as lamination (that is, covering the label surface with a transparent film), the waterproof performance of self-adhesive copper plate label paper can be significantly improved. The surface of the coated label paper is more smooth, which can effectively block the penetration of water, so as to achieve the waterproof effect to a certain extent.

In addition, the waterproof performance of self-adhesive copperplate label paper is also affected by self-adhesive pressure sensitive adhesive. The quality and formulation of the pressure sensitive adhesive will also have a certain impact on its waterproof performance. High quality pressure-sensitive adhesives maintain good stickiness in wet environments, reducing the risk of the label falling off.

In practical applications, the waterproof performance of self-adhesive copperplate label paper may decrease after it is soaked in a humid environment or for a long time. Therefore, when selecting self-adhesive copper plate label paper, users need to evaluate its waterproof performance according to the specific use environment and needs, and consider whether special treatment such as laminating is needed to improve the waterproof effect.

In summary, the waterproof performance of self-adhesive copperplate label paper is a relative concept, and the specific performance depends on multiple factors such as the substrate, pressure sensitive adhesive and production process. The user needs to select and process according to the actual situation.
