ABSTRACT:
This invention relates to novel blends containing degraded crystalline polypropylene or propylene containing copolymer useful as extrusion coating compositions which provide coatings having good coatability and good heat sealability. These coated substrates then can be used in fabricating bags and other packaging applications. Particularly, these coatings are a blend of a degraded crystalline polypropylene, or propylene containing copolymer, and low density polyethylene.
