FOAMED POLYPROPYLENE-BASED-RESIN SHEET, PROCESS FOR PRODUCING FOAMED POLYPROPYLENE-BASED-RESIN SHEET, AND PRESSURE-SENSITIVE ADHESIVE SHEET

摘要

Provided is a foamed polypropylene-based-resin sheet which after being compressed, can keep the compressed shape satisfactory.The foamed polypropylene-based-resin sheet according to the present invention is a foamed object of a resin composition comprising a polypropylene-based resin and at least one polymer selected from among olefin-based thermoplastic elastomers and polyethylene-based plastomers, wherein a center region, a first outer-side region, and a second outer-side region each have a resin proportion of 25-85%, and the center region, the first outer-side region, and the second outer-side region each have 1-100 cells.
