SKIN PACK SHEET
In skin packaging, the product itself is the mold. A high porous sheet, upon which a product is pre-positioned, is coated with surlyn adhesive (milky finish) and as a surlyn film is heated and dropped over the product by atmospheric pressure, it adheres to the sheet.
Normally, a skin board has a thickness of 0.024 pts. In the case of quite a heavy product, the printing can be done on 0.037 pts or corrugated of 175-200 lb test, by lamination.
In order to keep the porosity of the board, we use an uncoated stock, changing to a glossy finish, when the film adheres to the board; it protects the product (cannot shift); in a multi-piece set, the film maintains parts in place preventing loss.
