Calendering: PVC banner fabric

The calendering method is to thoroughly stir a variety of raw materials such as PVC powder and liquid plasticizer, and then bond with the base fabric by a pressure of a high-temperature heat roller. It is characterized by good surface flatness and uniform light transmission, and has an advantage in the inner lighting cloth. However, due to the limitations of the equipment, the width is generally no more than 3 meters. The 645 and 945 light box cloths developed by 3M Company of the United States are all produced by this process; the Lexi light box cloth developed by LG Korea is also representative of such a process.
