OLEFIN RESIN FOAM STRETCH MOLDED BODY

摘要

This foam stretch molded article is formed from an olefin resin single-layer structure, is formed by physical foaming at a foam expansion rate of 1.01-2.0, and is characterized by having a surface roughness (Ra) (JIS-B-0601-1994) in an area having foam cells distributed therein of no more than 10 µm. Despite being an olefin resin single-layer structure, this foam stretch molded body effectively suppresses external appearance defects and reduction in light-shielding properties that are caused by foam.
