Title:
HEAT-SHRINKABLE FILM
Document Type and Number:
Japanese Patent JP2023055726
Kind Code:
A
Abstract:
To provide a heat-shrinkable film suitable for printing using a biomass ink.SOLUTION: A heat-shrinkable film is one on which an ink layer formed by a biomass ink is laminated, and which includes a printed layer. The printed layer is composed of a thermoplastic resin, and includes a printed surface on which the ink layer is laminated. Oxidation induction time T (min) of the printed layer satisfies 0.15≤T≤12. The oxidation induction time T is oxidation induction time T1 measurable in air of 200°C or oxidation induction time T2 measurable in air of 230°C, or alternatively either one of T1 and T2 which is shorter.SELECTED DRAWING: Figure 4
