Document Type and Number:
Japanese Patent JP3666387
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain both a polypropylene resin composition having excellent injection, stretch and blow moldability and simultaneously improving rigidity, gloss, transparency, flexibility and impact strength in good balance, with which a container having excellent squeezing properties can be obtained and a container comprising the resin composition.
SOLUTION: This resin composition comprises (A) 100 pts.wt. of a polypropylene resin having 20-60 g/10 minutes melt flow rate (ASTM D 1238, 230°C, 2.16 load), 2.2-4.0 molecular weight distribution obtained from gel permeation chromatography and 2-4 wt.% of ethylene content and (B) 0.05-0.5 pt.wt. of nucleating agent. This container comprises the resin composition.
