Calendering method light box fabric: The calendering method is to fully stir PVC powder liquid plasticizer and other raw materials, and then bond them with the base fabric into a whole under the pressure of high-temperature hot rollers.
It is characterized by good surface smoothness and uniform light transmission, which is more advantageous in interior lighting fabric. However, due to equipment limitations, the width generally does not exceed 3 meters. The 645 and 945 lightbox fabrics developed by the American 3M Company are both produced using this process; the Lexi light box fabric developed by the Korean LG Company is also representative of this type of technology.
