POLYOLEFIN RESIN FOAMED SHEET AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide polyolefin resin foamed sheets which inhibit breakage of foamed cells not to cause craters and blisters and have a uniform foamed cell diameter, and a method of manufacturing the same. SOLUTION: The polyolefin foamed sheets comprise 60-97 wt.% high density polyethylene resin having a melt flow rate of 0.2-2 g/10 min and 3-40 wt.% at least one polypropylene based resin having a melt flow rate of 1-8 g/10 min selected from a homopolypropylene resin and a block polypropylene resin.
