| 摘要 |
Polymer compositions having elastomeric features, such as an extended elastic domain, are provided. The polymer compositions of the invention, which are useful in packaging materials, for example pallet stretch hoods, comprise a polyolefin; an ethylene vinyl acetate copolymer, an ethylene methyl acrylate copolymer, or a combination of ethylene vinyl acetate copolymer and a ethylene methyl acrylate copolymer; a metallocene catalyzed polyethylene; and, optionally, an ethylene acid copolymer.
