POLYPROPYLENE FILM FOR IN-MOLD LABEL

摘要

PROBLEM TO BE SOLVED: To provide a polypropylene film suitable for in-mold label use.SOLUTION: A polypropylene film for in-mold label mainly contain a polypropylene resin and has a thermal shrinkage at 150°C in an MD direction and a TD direction both of 9% or less, a Young's modulus in the MD direction of 2 GPa or more, and the Young's modulus in the TD direction of 4 GPa or more and haze of 6% or less. A lower limit of isotactic mesopentad fraction of the polypropylene resin contained in the film is 96% and the lower limit of face orientation coefficient is 0.0125.
