    摘要: Films (or a cap layer of co-extruded films) and methods of forming the same are described herein. The films generally include a modified olefin based polymer including polypropylene and from 1 wt. % to 30 wt. % polylactic acid (PLA), wherein the modified olefin based polymer exhibits a seal initiation temperature (SIT) that is at least 5° C. less than a seal initiation temperature of the polypropylene absent the PLA and a hot tack range of at least 20° C.

    摘要: Alicyclic carboxylates, such as alicyclic norbonane sodium dicarboxylate, may be used in relatively small amounts as crystallization nucleating agents for foamed polypropylene. The alicyclic carboxylates give improved cell structures at lower proportions than conventional crystallization nucleating agents. The use of alicyclic carboxylate crystallization nucleating agents together with conventional nucleating agents may help give lower density polypropylene foams across a broader melt temperature range.

    摘要: Biodegradable polymeric compositions and processes for making such are described herein. The processes generally include providing an olefin based polymer selected from polypropylene, polyethylene, combinations thereof and copolymers thereof and contacting the olefin based polymer with polylactic acid in the presence of a reactive modifier to form the biodegradable polymeric composition, wherein the reactive modifier is selected from oxazoline-grafted polyolefins, maleated polyolefin-based ionomers, isocyanate-functionalized polyolefins and combinations thereof.
