According to the production process, PVC flex banner is divided into three types: PVC flex banner with knife scraping method, PVC flex banner with calender method and legal PVC flex banner.
Blade scraping
The knife-scraping method for PVC flex banner is to apply liquid PVC slurry uniformly to both the front and back sides of the base cloth with a number of anti-squeegee blades, and then completely combine them into a whole through a drying process, and then cool to form. Its characteristics are strong anti-penetration, tensile strength, and resistance to peeling. Because the upper and lower parts of the blade scraping method are a whole, the peeling phenomenon can be eliminated, and the strength of the splicing place can be greater than the product itself by welding. At present, the width of the PVC flex banner of this process can reach 5 meters. Due to the complicated production process and relatively expensive production equipment, such products are mainly imported in the Chinese market with relatively high prices.
Calendering
The calendering method is to fully agitate various raw materials such as PVC powder and liquid plasticizer, and then bond with the base cloth into a whole by the pressure of a high-temperature hot roller. Its characteristics are better surface flatness, and uniform light transmission, which has advantages on internal lighting cloth. But limited by the equipment, the width is generally not more than 3 meters.
Legal
Adhering to the PVC flex banner, the upper and lower layers are formed into a PVC film, which is heated and pressed under the pressure of a heat roller to the middle of the light guide fiber web, and then cooled and formed. The biggest feature of this process is that it has excellent ink absorption and strong color expression. Therefore, with the rise of large-scale inkjet printing industry, this kind of PVC flex banner has brought unlimited vitality. At present, the market share of this type of PVC flex banner in China has exceeded 70%.

Therefore, she maximizes space utilization, beautifies the environment, saves transportation costs, simplifies installation procedures, and broadens application scope. Especially the environment with strict requirements on space use, such as: elevators, public passages, shopping malls, supermarkets, subways, stations, etc., is the most ideal place for ultra-thin light boxes.
