Patent ID: 6875484

Claim:
A skin-bearing article molded from a multi-layer foamed parison having inner surfaces mutually welded, comprising: a foamed polypropylene resin layer having a density of 25 to 400 kg/m 3 formed from a first raw resin, and an unfoamed polypropylene resin layer formed from a second raw resin provided on the outer side of the foamed polypropylene resin layer said first raw resin forming the foamed polypropylene resin layer having a melt tension, MT fr (gf), and a melt flow rate, MFR fr (g/10 min), and satisfying the following relationship (1), and said second raw resin forming the unfoamed polypropylene resin layer having a melt tension, MT ur (gf), and a melt flow rate, MFR ur (g/10 min), and satisfying the following relationships (2) and (3) log MT fr >−0.74 log MFR fr +0.66 (1) log MT ur >−1.02 log MFR ur +0.47 where MFR ur ≧0.3 (2) MT ur ≧10 (gf) where 0.1≦MFR ur <0.3 (3).
