How waterproof is the circular colored copperplate label paper?

The waterproof performance of circular colored copperplate label paper is relatively weak. The following is a detailed analysis of its waterproof performance:

1、 Material characteristics

Copperplate paper is mainly made of wood pulp or cotton pulp, with a uniform and dense surface, good paper whiteness, and delicate texture, suitable for various printing processes. However, due to its main component being cellulose, it is prone to moisture deformation, which affects the performance and printing effect of the paper. Therefore, copperplate paper itself does not have excellent waterproof performance.

2、 Waterproof treatment

Although copperplate paper itself has poor waterproof performance, its waterproof performance can be improved through some processing methods. For example, coating a layer of waterproofing agent on the surface of copperplate paper can form a waterproof barrier, preventing moisture from penetrating into the interior of the paper. This waterproof treated copperplate paper label can improve its waterproof performance to a certain extent, but the specific effect depends on the quality of the waterproofing agent and the coating process.

3、 Usage environment

The waterproof performance of copperplate paper labels is also affected by the usage environment. In humid environments, copperplate paper is prone to moisture, causing problems such as deformation, yellowing, and mold growth, which can affect the printing effect and service life. Therefore, when using copperplate paper labels, it is advisable to avoid prolonged exposure to humid environments.

4、 Waterproof evaluation

For the waterproof evaluation of circular colored copperplate label paper, multiple factors such as material, waterproof treatment, and usage environment need to be comprehensively considered. Generally speaking, copper coated paper labels without waterproof treatment have poor waterproof performance and are prone to moisture deformation; Copper coated paper labels that have undergone waterproof treatment can improve their waterproof performance to a certain extent, but the specific effect varies depending on the treatment method and usage environment.

In summary, the waterproof performance of circular colored copperplate label paper is relatively weak, but its waterproof performance can be improved through waterproof treatment and control of the usage environment. When choosing label paper, the selection should be based on specific usage requirements and environmental conditions.
