Product Description
This line is designed for manufacturers of optical and functional films. The coating method can be chosen to suit the coating material and film structure of each product, and two-roll or three-roll laminating allows a coated web to be combined with a second layer where required.
Unwinding and rewinding units support manual, flying blade, gear blade or hot melt cutting, with pneumatic fixed cone, movable open-close arm cone or air shaft clamping. The working speed of up to 150 m/min depends on the material and process. Contact JWELL with your substrate, coating material, width and target application for a configured proposal.
