ABSTRACT:
A layered film sheet which can coat a sheet-like subject and is folded to coat the subject. In the folded, layered film sheet, an embossed polyvinyl chloride film exists as an outermost layer, an EVA film serves as an innermost layer in direct contact with the subject and a low density polyethylene film, an EVA film and a polyester film are intermediately inserted therebetween. The LDPE film and the polyester film are bonded to the outermost layer and the innermost layer via water-miscible acryl adhesives respectively. The innermost layer is softened and made adhesive at low temperatures and thus, the total coating process can be conducted at decreased temperatures so that the outermost PVC film can be expressed in effective embossed patterns.
