PRINTING FILM OF POLYLACTIC ACID, PRINT, AND LABEL FOR IMITATION CAN IN VENDING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide an oriented polylactic acid film which is excellent in printability for a solvent-less ink and ultraviolet curable printing ink adhesion in particular and has sufficient blocking resistance.

SOLUTION: In the biaxially oriented laminated film containing polylactic acid as a main component and comprising at least two layers, at least one surface layer is constituted of polylactic acid with a crystal melting heat quantity (ΔHm-ΔHc) of 4-23 J/g. The shrinkage ratio of the film after the film is kept at 80°C for 200 hr is -2% to 3% in both longitudinal and width directions.
