摘要

PROBLEM TO BE SOLVED: To provide a resin composition having excellent transparency, heat resistance and resistance to staining with foods, and a storage container obtained therefrom. SOLUTION: This composition consists of 100 pts.wt. propylene homopolymer having a melt flow rate of 4-20 g/10 min, 0.05-0.5 pt.wt. phosphorus antioxidant, 0.1-1.0 pt.wt. amine-base antioxidant, and 0.1-1.0 pt.wt. nucleating agent comprising a compound represented by the formula (wherein R1 and R2 are each independently H or alkyl; and X is alkylidene). The storage container used for colored foods is obtained by injection molding this composition.
