How is the three heat-proof label paper waterproof

Three heat-proof paper waterproof function mainly through the following ways:

Special coating treatment: During the manufacturing process, a special waterproof coating will be coated on the surface of the three heat-resistant paper. This coating can form an effective waterproof barrier that makes it difficult for moisture to penetrate the inside of the paper, thereby protecting the printed content from water erosion.

Coating treatment: In addition to coating treatment, the three heat sensitive paper may also be coated. In this process, the surface of the paper will be covered with a waterproof film, such as BOPP, PET and other materials. This film further enhances the waterproof properties of the paper, ensuring that the print remains visible in light water droplets or wet environments.

Special manufacturing process of thermal label paper: For thermal label paper, it has waterproof, oil resistance and other characteristics. This is achieved through a special manufacturing process, which involves covering the surface of the paper with a waterproof material. This material can effectively resist the erosion of moisture and grease, so that the label can still maintain a good printing effect in harsh environments.

It should be noted that although the three thermal sensitive paper has a certain waterproof function, it does not completely prevent water penetration. In the case of prolonged immersion or extreme humidity, the printed content may still be affected. Therefore, when using three heat-proof paper, it should be reasonably selected and used according to the specific application scenario.

If the waterproof function requirements are relatively high, you can choose thermal synthetic paper, PET transparent thermal label paper, thermal silver paper and so on

In general, the three heat-proof paper achieves waterproof function through special coating treatment, laminating treatment and special manufacturing process of heat-sensitive label paper. Together, these treatments improve the water resistance of the paper, making it suitable for more applications that require water resistance.
