Abstract:
1. A label for in-mold forming, comprising: a thermoplastic resin film base layer (I); and a heat-sealable resin layer (II); wherein: the heat-sealable resin layer (II) comprises a copolymer of ethylene and an α-olefin having 3 to 20 carbon atoms; the heat-sealable resin layer (II) has an adhesion strength as measured at 23° C. of 300 gf/15 mm or higher; the heat-sealable resin layer (II) has an adhesion strength as measured at 90° C. of 290 gf/15 mm or lower; the heat-sealable resin layer (II) has a proportion of heat of fusion in a range of temperatures below 90° C. of 70% or higher as determined with a differential scanning calorimeter (DSC); and the copolymer of the heat-sealable resin layer (II) has a melting point of 50-90° C.
