The calendering method is to fully mix PVC powder with liquid plasticizer and other raw materials, and then bond them to the base fabric under the pressure of high-temperature hot rollers. Its characteristics are good surface flatness and uniform light transmittance, which is more advantageous in internal lighting cloth. However, due to the limitation of equipment, the width is generally not more than 3 meters. The 645 and 945 light box cloths developed by 3M Company in the United States are both produced by this process; the Lucky light box cloth developed by LG Company in South Korea is also a representative of this process.
