Zusammenfassung:	PURPOSE: To obtain the subject composition, comprising a propylene-ethylene block copolymer, a propylene-ethylene random copolymer and a nucleating agent and capable of providing transporting containers, etc., without adversely affecting the taste and an aroma of a favorite food, a food, etc. CONSTITUTION: This resin composition comprises (A) a block copolymer of propylene and ethylene [preferably having 20000-600000 weight-average molecular weight(Mw), 5-8 molecular weight distribution and 4-9wt.% ethylene content], (B) a random copolymer of propylene and ethylene (preferably having 20000-600000Mw, 5-8 molecular weight distribution and 2-5wt.% ethylene content) and (C) a nucleating agent [preferably a bis(p-alkylbenzylidene)sorbitol-based nucleating agent]. Furthermore, the respective components are preferably blended so as to contain 80-90wt.% component (A), 10-20wt.% component (B) and 0.1-1wt.% component (C) in the composition. A di-(2-hydroxyethyl)alkylamine- based antistatic agent is preferably blended in the composition.
