ABSTRACT:
A process for producing synthetic label paper which comprises preparing a multi-layer film comprising a film of a thermoplastic resin containing an inorganic fine powder having provided on the back side thereof a layer of a heat-sealable resin having a melting point lower than that of said thermoplastic resin, embossing the heat-sealable resin layer, and stretching the embossed multi-layer film at a temperature of from the melting point of said heat-sealable resin to a temperature lower than the melting point of said thermoplastic resin. The label paper, when used for in-mold decorating of a container, gives a blister-free appearance to a container, causes no deformation of a container, and exhibits sufficient nerve for fitting to an inner wall of a mold.
