Heat Shrinkable Film

Abstract: Provided is a heat-shrinkable film for lamination of an ink layer formed from a biomass ink, wherein a printing layer is provided. The printing layer is configured from a thermoplastic resin and has a printing surface on which an ink layer is to be layered. The oxidation induction time T (min) of the printing layer satisfies 0.15=T=12. The oxidation induction time T is an oxidation induction time T1 measurable in air at 200°C, an oxidation induction time T2 measurable in air at 230°C, or the shorter of T1 and T2.
