RESIN COMPOSITION FOR POLYPROPYLENE FILM COMPRISING POLYPROPYLENE HOMOPOLYMER WITH ISOTACTIC PENTAD INDEX OF 95 OR MORE AND DISTRIBUTION OF MOLECULAR WEIGHT OF 8 OR LESS, CALCIUM STEARATE OR ZINC STEARATE, AND HYDROTALCITE

摘要

PURPOSE: Provided is a resin composition for a polypropylene film which is excellent in stiffness, heat shrinkage and curling resistance, has a low crystallization temperature and is reduced in the surface transfer of additives. CONSTITUTION: The resin composition comprises 100 parts by weight of a polypropylene homopolymer resin which has an isotactic pentad index of 95 % or more and a distribution of molecular weight of 8 or less; 0.01-0.04 parts by weight of calcium stearate or zinc stearate as a Cl inactivator; and 0.01-0.03 parts by weight of hydrotalcite.
