A1
Abstract:
A container including a layer made of a resin composition containing: 57 to 75 mass% of propylene-based resin (A) which satisfies (a1) through (a4); 10 to 25 mass% of ethylene-based resin (B) which satisfies (b1) through (b3); and 10 to 18 mass% of propylene-based elastomer resin (C) which contains 50 mol% or more of constituent units derived from propylene and constituent units derived from α-olefins having 2, or 4 through 20 carbon atoms, and which satisfies (c1) through (c4) (assuming the total of (A) through (C) as being 100 mass%).
