Polyolefin Resin Foam Sheet And Method For Producing Same

Abstract: The present invention provides: a foam sheet made of polyolefin resin, wherein the polyolefin resin foam sheet is characterized in that the thickness of the foam sheet is 0.05-0.5 mm, the apparent density is 200-500 kg/m3, the tensile strength at 100% elongation in the lengthwise direction (MD direction) and/or the widthwise direction (TD direction) of the sheet is 3.5-12 MPa, and the ratio of the tensile breaking strength and the tensile strength at 100% elongation in the MD direction and/or the TD direction of the sheet is 1.0-1.8; and a method for producing the foam sheet. The present invention can provide a polyolefin resin foam sheet having excellent reworkability and excellent shock absorption even as a thin foam sheet.
