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