摘要 |
<p>A polyolefin resin foamed sheet comprising a polyolefin foamed layer and a polyolefin non-foamed layer. The non-foamed layer contains /-10 wt.% recycled polyolefin subjected to at least two cycles of a process comprising melting and solidifying a polyolefin selected from polyolefins with long chain branches or polyolefins with a weight-average molecular weight of /-1/*10<5>. An Independent claim is included for a method of producing the inventive polyolefin resin foamed sheet comprising co-extruding the polyolefin foamed layer and polyolefin non-foamed layer, and foaming the polyolefin resin layer.</p> |
