Abstract:
A heat shrinkable film for labeling comprising at least one layer of a thermoplastic resin, in whose correlation diagram showing the relation between the heat shrinkage percentage Y at 80.degree. C. in one direction and the heat shrinkage time t (1.ltoreq.t.ltoreq.5), the gradient Y' is in the area between the gradients satisfying Equations 1 and 2 and the heat shrinkage percentage Y is in the area between the heat shrinkage percentages satisfying Equations 3 and 4:Y'=-1.05t.sup.2 +12.05t (Equation 1)Y'=-0.30t.sup.2 +2.90t (Equation 2)Y=-1.05t.sup.2 +12.05t+40 (Equation 3)Y=-0.30t.sup.2 +2.90t+9 (Equation 4).
