To ensure the stability of the color of BOPP color thermal synthetic paper, it is necessary to start from many aspects, including material selection, production process control, storage conditions and consideration of the use environment. Here are some specific measures:
1. Material selection and quality control
Substrate selection: The selection of high-quality BOPP film as the substrate to ensure the physical properties and chemical stability of the film, laying a solid foundation for color stability.
Dyes and pigments: Choose dyes or pigments with good stability for thermal coatings and color printing layers. These dyes or pigments should have good light resistance, water resistance, chemical corrosion resistance and other properties to reduce the influence of external factors on color stability.
Additive use: In the production process, the rational use of antioxidants, anti-ultraviolet agents and other additives to improve the overall stability and durability of the material.
2. Production process control
Coating preparation: The preparation process of thermal sensitive coating is strictly controlled to ensure the uniformity and stability of the coating. The uniformity of coating thickness has an important effect on the stability of color.
Printing process: In the process of color printing, precise printing process and equipment are used to ensure the clarity of the printed pattern and the accuracy of the color. At the same time, pay attention to control the printing speed and pressure to avoid unnecessary damage to the material.
Post-treatment: After the completion of printing, appropriate post-treatment processes, such as drying, curing, etc., are carried out to improve the adhesion and durability of the printed pattern.
3. Storage conditions
Temperature and humidity: BOPP color thermal synthetic paper is stored under appropriate temperature and humidity conditions to avoid adverse effects on the material caused by high temperature, high humidity or extreme temperature changes. Generally, it is recommended to store in an environment with a temperature of 2025 ° C and a humidity of 50%60%.
Light protection: Avoid prolonged exposure to strong light, especially ultraviolet radiation, which accelerates the fading process of dyes or pigments.
Packaging and isolation: Packaging BOPP color thermal synthetic paper with appropriate packaging materials to isolate external pollution sources such as dust and impurities.
4. Use environment consideration
Application scenario assessment: Evaluate the specific application scenarios of BOPP color thermal synthetic paper before use to understand the external challenges it may face (such as moisture, chemicals, friction, etc.) in order to select the appropriate material specifications and production processes.
Protective measures: Take necessary protective measures during use, such as coating protective layer and avoiding direct contact with chemical substances, to extend the service life of the material and maintain the stability of the color.
5. Regular testing and feedback
Color stability test: BOPP color thermal synthetic paper is regularly tested for color stability to evaluate its performance under actual conditions of use. These tests can include light resistance tests, water resistance tests, chemical resistance tests, etc.
Customer feedback collection: actively collect feedback from customers in the process of use, and understand the problems and improvement directions of materials in practical application. Continuously improve the color stability of products through continuous improvement of production processes and material formulations.
To sum up, ensuring the stability of the color of BOPP color thermal synthetic paper requires comprehensive consideration of multiple aspects of material selection, production process control, storage conditions and use environment. By implementing these measures, the color stability and durability of BOPP color thermal synthetic paper can be effectively improved.
