Abstract
Methods for extrusion coating a substrate are provided. The methods comprise applying an extrusion coating composition to a surface of a substrate by extrusion coating. In these methods, the extrusion coating composition includes a polyolefin and an inorganic particulate material having an average particle size of no greater than 2 μm and a particle loading of at least 20 weight percent, based on the total weight of polyolefin and the inorganic particulate material.
Claims12
A method for extrusion coating a substrate, the method comprising applying an extrusion coating composition to a surface of the substrate by extrusion coating, whereby the extrusion coating composition contacts a chill roll surface, the extrusion coating composition comprising:
- (a) a polyolefin;
- and
- (b) an inorganic particulate material having an average particle size of no greater than 1.5 μm and a particle loading of at least 20 weight percent, based on the total weight of the polyolefin and the inorganic particulate material in the coating composition.
A coated substrate comprising:
- (a) a substrate;
- and
- (b) a coating composition coated on a surface of the substrate, the coating composition comprising:
- (i) a polyolefin;
- and
- (ii) an inorganic particulate material having an average particle size of no greater than 1.5 μm and a particle loading of at least 20 weight percent, based on the total weight of the polyolefin and the inorganic particulate material.
