樹脂組成物および熱収縮性フィルム

Japanese Patent JP5328069

B2

PROBLEM TO BE SOLVED: To provide a resin composition useful for a raw material of a heat- shrinkable film excellent in heat-shrinkable properties, natural-shrinking resistance and rigidity, and to provide a film using the same. SOLUTION: The resin composition comprises a component A, a component B and a component C as main components. The component A is a copolymer composition comprising or mainly comprising a block copolymer consisting of a vinyl aromatic hydrocarbon and a conjugated diene and having a block mainly comprising the vinyl aromatic hydrocarbon and a block mainly comprising the conjugated diene, in which the relation of the loss tangent value obtained by dynamic viscoelasticity measurements to temperature satisfies specific conditions. The component B is a styrenic copolymer different from the component A consisting of a vinyl aromatic hydrocarbon and a conjugated diene, in which the loss tangent value obtained by dynamic viscoelasticity measurements has a maximum value within the range of from 65 deg.C to below 100 deg.C. The component C is styrenic resin different from the component A and the component B.
