Abstract:
A label, comprising:a substrate (I) comprising a thermoplastic resin film comprising a thermoplastic resin; and a layer (II) comprising a heat-sealable resin film comprising a polyethylenic resin having a crystallinity of 10 to 60% selected from the group consisting of a low density to medium density of polyethylene having a density of from 0.900 to 0.935 g/cm3; linear polyethylene having a density of 0.880 to 0.940 g/cm3; ethylene/vinyl acetate copolymers; ethylene acrylic acid copolymers; ethylene/alkyl acrylate copolymers in which the alkyl group has 1-8 carbon atoms; ethylene/alkyl methacrylate copolymers in which the alkyl group has 1-8 carbon atoms; metal salts of ethylene/methacrylic acid copolymers; and a linear polyethylene prepared by polymerizing 40 to 98% by weight ethylene and 60 to 2% by weight of a C3-30 &agr;-olefin; and 0.05% to 10% by weight of at least one fatty acid amid having a molecular weight of 300 to 1000 and a melting point of 60 to 160Â° C. and optionally an organic fine powder having an average particle size greater than the thickness of layer (II); wherein the layer (II) is disposed on one surface of the layer (I), and has a thickness of at least 1 &mgr;m.
