The surface treatment methods for BOPP thermal sensitive synthetic paper mainly include the following:
1、 Corona treatment
Principle: Air is ionized by a high-frequency and high-voltage electric field, generating plasma. The charged particles in this plasma collide with the surface of BOPP film, causing the molecular chains on the surface to break and form polar groups, thereby increasing the surface tension of the film.
Purpose: To improve the surface properties of the film and enhance the adhesion between the coating layer or printing ink and the film.
2、 Other surface treatment methods
In addition to corona treatment, other surface treatment methods such as chemical treatment, flame treatment, etc. can be used according to specific needs to further improve the surface properties of BOPP thermosensitive synthetic paper. The specific implementation methods and effects of these methods may vary depending on factors such as the type of treatment agent, treatment temperature, and treatment time.
It should be noted that when selecting and processing the surface treatment method for BOPP thermal sensitive synthetic paper, factors such as the paper's purpose, required performance, and cost should be fully considered. At the same time, in order to ensure the consistency and stability of the treatment effect, the treatment process parameters and operating procedures should be strictly controlled.
In addition, BOPP thermal sensitive synthetic paper that has undergone surface treatment also needs to pay attention to protecting its surface properties during subsequent processing and use, avoiding the influence of adverse factors such as pollution and scratches, to ensure the quality and performance of its final product.
