Abstract
The present invention discloses a device and a method for processing the impression structure of 3-layer co-extruded biaxial oriented polypropylene (BOPP) pearl synthetic paper. The depth of the impression on the synthetic paper is between 0.2-1000 μm which is embossed by the modified embosser. The 3-layer co-extruded pearl synthetic paper is processed for cooling, biaxial orientation, corona treatment and winding and then passing through the modified embosser to preheating, calender, cooling. The modified embossing device comprises a rubber back-up roll having at least Shore A hardness of 60-90; an embossing roll with a designed pattern and a cooling system having a core; a quartz electric heating oven preheated to 65° C. to 160° C.; a infrared heater; and two adjacent cooling drums with 7° C.
