On the one hand, the coating is like a barrier layer, which can block the migration of additives to the film surface; On the other hand, the layer remains active for a long time on the film surface.
The question now is, is pretreatment of coating really necessary? Because most printing machines can be equipped with corona treatment devices nowadays, it is theoretically possible to print thin film materials without pretreatment coating.

Therefore, attention should be paid to the stool mould in the production process in order to improve the production efficiency.
Don't just focus on product design, ignoring stool mould parts manufacturing. When some users develop products or trial-produce new products, they usually only pay attention to product development and development at the initial stage, ignoring the communication with the stool mould parts manufacturing unit. After the preliminary determination of the product design plan, there are two benefits to contacting the mold manufacturer in advance:
1. It can ensure that the designed product has a good forming process and will not modify the shaping design because the parts are difficult to process.
2. Mold makers can make design preparations in advance... less
