Abstract
This invention relates to low density polyethylene extrusion coating compositions which provide coatings having good coatability and a broad heat seal range. The coated substrates can be used in fabricating bags and other packaging applications. These unique extrusion coatings are provided by a low density polyethylene having a density of 0.916 to 0.926, a melt index of 0.1 to 2.0 and a swell ratio of less than 1.5.
