Foamed Polyolefin Based Resin Sheet

Abstract: A foamed polyolefin-based resin sheet which is a foamed sheet comprising a polyolefin-based resin, characterized by having a thickness of 0.05-0.5 mm, a hardness at 25% compression measured in accordance with JIS K6767 (1999) of 20-100 kPa, a ratio of the longitudinal-direction cell diameter to the thickness-direction cell diameter of 9-30, and a ratio of the width-direction cell diameter to the thickness-direction cell diameter of 9-30. The present invention can provide a foamed polyolefin-based resin sheet which, although thin, is excellent in terms of compression flexibility, reworkability, and punchability.
