(57) Abstract: The present invention is to provide a multilayer polypropylene resin foam board which is lightweight, rigid, and excellent in folding resistance and low-temperature impact resistance. The present invention relates to a resin layer (A) comprising a polypropylene resin composition containing a thermoplastic elastomer on at least one surface of a polypropylene resin foam layer. Are laminated, the number of times of folding measured according to JIS P 8115 is 1000 or more, and the flexural modulus is 200 MPa or more. The multilayer polypropylene resin foam board of the present invention is particularly excellent in bending resistance and low-temperature impact resistance, It is suitable as a material for various containers and container partition plates, a core material, a returnable box such as a cardboard box, and a storage box. |
