Double Embossing Release Paper Lamination Line for Leather Texture Transfer
This release paper production equipment is a professional equipment that integrates polymer coating technology and embossing process. It is specially used to manufacture patterned release paper for thermal transfer of artificial leather. The equipment evenly covers the molten polypropylene (PP) on the surface of the base paper and completes the embossing molding simultaneously, so that the release paper has excellent characteristics such as high temperature resistance, good peelability, clear and transferable patterns.
The equipment adopts PLC intelligent control system, with functions such as automatic unwinding, precise tension control, precise temperature adjustment and fast replacement of embossing rollers. It is widely used in surface texture transfer processes such as PU leather, PVC leather, shoe leather, furniture leather, etc. It is an ideal choice for leather manufacturing and material processing companies.
Whether it is large-scale standard production or small-batch diversified customization, the equipment can provide efficient and stable solutions to help customers improve product added value and market competitiveness.
