| description | PURPOSE:To obtain a laminated foamed sheet having beautiful appearance low in an open cell ratio and density by laminating a synthetic resin foamed sheet having fine air bubbles on at least one surface of a specific polypropylene resin foamed sheet. CONSTITUTION:A polypropylene resin foamed laminated sheet having beautiful appearance is constituted by laminating a synthetic resin foamed sheet having air bubbles finer than those of a specific polypropylene resin foamed sheet on at least one surface of the polypropylene resin foamed sheet. The specific polypropylene resin foamed sheet is formed from a mixture of 60-100wt.% of a specific propylene resin (A) and 0-40wt.% of a propylene copolymer resin (B) and the density thereof is set to 0.5-0.25g/cm . The specific resin (A) is set so that a Z average mol.wt. Mz is 2.0X10 and Mz/Mw is 3.0 and contains a branched polymer in its high-molecular region. |
