PVC canvas banner is divided into three types according to the production process: a knife scraping light box cloth, a calendering light box cloth and a legal light box cloth.

Real knife coated PVC banner Backlit:

The knife-scraping light box cloth process is to apply the liquid PVC slurry to the front and back sides of the base cloth with a plurality of anti-scraping blades, and then completely combine them into a whole by a drying process, and then cool and form. It is characterized by strong resistance to penetration, tensile strength and peeling resistance. Since the upper and lower parts of the knife scraping method are integrated, the peeling phenomenon can be eliminated, and the strength of the joint is greater than that of the product itself by welding.

At present, PVC banner black width of this process can reach 5 meters. Due to the complicated production process and the relatively expensive production equipment, such products are mainly imported in the Chinese market, and the price is relatively high. The most representative ones are German-made ULTRALON, South Korea-based UNIFLEX and Belgian-made SIOEN.
