Abstract
The present disclosure provides a polyolefin-based composition suitable for use as adhesives and/or tie-layer adhesive compositions as well as multi-layered structures made from and/or containing the polyolefin-based composition. The polyolefin-based composition is made from and/or contains (a) a grafted polyolefin composition, (b) a linear low density polyethylene composition made from and/or containing metallocene-catalyzed linear low density polyethylene having a melt index from about 2 to about 10 grams per 10 minutes, (c) an elastomer composition made from and/or containing an polyethylene elastomer, (d) a hydrocarbon-based tackifier, and (e) optionally, an additives composition having one or more additives.
