Abstract

The present disclosure provides a polyolefin-based composition suitable for use as adhesives and / or tie-layer adhesive compositions as well as a multi-layered structure 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 first polymer composition, (c) a polypropylene-containing blend composition, and (d) optionally, an additives composition having one or more additives.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a Continuation Patent Application, which claims benefit of priority to U.S. Non-Provisional application Ser. No. 14 / 645,488, filed Mar. 12, 2015 and U.S. Provisional Application No. 61 / 968,825, filed Mar. 21, 2014, the contents of which are incorporated herein by reference in their entirety.FIELD OF THE INVENTION[0002]The present disclosure relates to polyolefin-based compositions useful as adhesives and / or tie-layer adhesive compositions for multi-layered structures. In particular, the compositions are useful as adhesives to bind a barrier layer to a dissimilar substrate.DESCRIPTION OF RELATED ART[0003]Multi-layer films and sheets are widely used for food packaging applications. Depending on the intended application, the number and arrangement of resin layers and the type of resins employed will vary. Polyethylene resins are often included as one of the layers for food contact and sealing properties. Ethylene-vinyl al...
