What is the water and moisture resistance of BOPP thermal synthetic paper?

The water and moisture resistance of BOPP thermal synthetic paper is relatively good, but the specific performance may vary due to factors such as product formulation, production process and use conditions. The following is a detailed analysis of its water and moisture resistance:

Water resistance

BOPP thermal synthetic paper, as a synthetic material, usually has a certain water resistance. Its water resistance mainly depends on the bonding fastness of the thermal coating with the BOPP substrate and the chemical stability of the coating itself. Under normal circumstances, BOPP thermal synthetic paper can resist a certain degree of moisture erosion and maintain the clarity and integrity of the printed content. However, under extreme conditions such as prolonged soaking or high-pressure water spraying, its water resistance may be affected to some extent.

Moisture resistance

Moisture resistance is one of the important characteristics of BOPP thermal synthetic paper. Because the BOPP substrate itself has a certain moisture resistance, coupled with the protective effect of the thermal coating, the BOPP thermal synthetic paper can also maintain good stability in a humid environment. Ingredients such as adhesives and stabilizers in the thermal coating help to enhance the moisture resistance of the coating and prevent moisture penetration from causing damage to the printed content.

Influencing factor

The water and moisture resistance of BOPP thermal synthetic paper may be affected by the following factors:

1.Product formulation: Different product formulations may lead to differences in the composition and proportion of the thermal coating, which in turn affects its water and moisture resistance.

2.Production process: The quality of the production process directly affects the combination fastness of the thermal coating with the BOPP substrate and the uniformity of the coating, thus affecting the water resistance and moisture resistance of the product.

3.Conditions of use: The use conditions of the product such as temperature, humidity, pressure, etc., will also affect its water resistance and moisture resistance. For example, in high temperature and humidity environments, the water and moisture resistance of the product may be reduced.

Promotion measure

In order to improve the water and moisture resistance of BOPP thermal synthetic paper, the following measures can be taken:

1.Optimize product formulation: By adjusting the proportion and variety of components in the thermal coating, improve its chemical stability and moisture resistance.

2.Improved production process: The use of advanced production process and equipment to ensure the strong combination of thermal coating and BOPP substrate and the uniformity of the coating.

3.Enhanced surface treatment: Surface treatment of the BOPP substrate, such as corona treatment, etc., to improve its surface energy, which helps to enhance the binding force of the thermal coating and the substrate.

4.Use moisture-proof agent: Add appropriate moisture-proof agent to the thermal sensitive coating to further improve the moisture-proof performance of the product.

In summary, BOPP thermal synthetic paper has good water resistance and moisture resistance under normal circumstances, but the specific performance needs to be comprehensively evaluated according to product formulation, production process and use conditions. During use, care should be taken to avoid prolonged immersion or exposure to extreme humidity in order to extend the service life of the product.
