The skin packaging adhesive/glue is used to coat onto the porous board, to ensure tenacious and durable bond between skin film and porous board in the skin packaging process. It leaves an ultra thin layer of off-white milky color on the board after coating process, non-stick and stable in chemical property. It can only be activated to become sticky and clear when heat is present from the heated skin film in contact with it. This material is non-solvent and environmentally friendly, and can be easily coated onto the porous board on the common roller coating machines.
