Secondary processing performance of plastic board processing
The various properties and characteristics of plastic board processing are higher than traditional packaging materials. With the development of society, it is used more and more, and it can be processed twice, which is a very environmentally friendly new material p>
Among them, high molecular polymer or synthetic resin is the main component of plastic. In order to improve the performance of plastic, various auxiliary materials must be added to the polymer, so that the performance of the plastic board will be improved. Another point is that there are two kinds of substances, which confuse polyvinyl chloride resin with polyvinyl chloride plastics, and phenolic resins with phenolic plastics. Resin and plastic are two different concepts: Resin is an unprocessed raw polymer that is not only used to make plastics, but also a raw material for coatings, adhesives, and synthetic fibers.
The secondary processing performance of plastic board is very good, its printing performance is better than polyethylene, photorelief, offset, planographic and gravure printing methods can be used. The products can be hot stamped, printed, bonded, etc. The bonding can be hot-bonded, solvent-based adhesives or high-frequency sealing, etc., hot air, thermal ultrasonic welding can be used, and the welding performance is good. Electroplating is used for decorative parts of instruments, meters, electronics, etc. To obtain the required printing performance such as heat resistance, oil resistance, water resistance, etc., printing must be performed after corona discharge treatment.
In recent years, the application of plastic sheet processing has become more and more extensive. It is because it can be recycled for secondary processing, so it is selected by the majority of users. While the product is thinner, the functionality is stronger, which promotes The higher rate of growth in this market has prompted the continuous emergence of new products.
