Abstract

PURPOSE: To provide a foamed article composed of a polypropylene resin and a polyethylene resin and, having high formability and excellent toughness, wherein the formability, the longitudinal tensile strength, and the longitudinal and transverse tensile elongations satisfy specific formulas.
CONSTITUTION: A foamed article composed of 90W10wt%, preferably 85W50% polypropylene resin and 10W90%, preferably 15W50% polyethylene, wherein the formability H/L [H is draw depth (cm) in drawing; L is draw diameter (cm) in drawing], the longitudinal tensile strength X (kg/cm2) of the foam, the longitudinal tensile elongation Sm (%), the transverse tensile elongation St (%), and the apparent density p (g/cm3) of the foam satisfy the following formulas, H/L≥ 0.60, X≥19-0.4/p, Sm≥280+4/p and St≥180+4/p.
