Abstract
A synthetic resin laminated paper is disclosed which comprises a synthetic resin film layer and a paper layer, the improvement wherein an adhesion-release control agent layer is interposed between the film layer and said paper layer. The synthetic resin laminated paper of the present invention can be easily separated into a laminated film and a paper by a mechanical treatment within a shortened period of time with minimum consumption of energy. Moreover, the pulverization of the laminated film is prevented and thus operation efficiency of separation is enhanced.
