<p><P>PROBLEM TO BE SOLVED: To provide a foamed sheet combining a relatively low expansion ratio, good surface smoothness, high dimensional precision and high impact resistance, and a foamed molding useful in transportation of e.g. large electronic parts. <P>SOLUTION: The sheet of a polypropylene type resin and a container made of the sheet comprise (A) a polypropylene type resin of a high melt tension having a composition in a specified range, (B) a linear crystalline polypropylene type resin and (C) a styrene - ethylene/butylene - styrene block copolymer and have a density equal to or higher than 180 kgm<SP>-3</SP>and lower than 850 kgm<SP>-3</SP>. Preferably, (C) has a content of ethylene of 10-40%. Preferably, (A) and (B) use resins of a specified MFR and has a specified blending ratio. <P>COPYRIGHT: (C)2004,JPO</p> |
