A decorative and functional substrate (10) consisting of a paper base sheet (11) coated with thermoplastic or thermoset material which provides grease resistance to the finished product. Grease resistance may be incorporated into one or more coatings (12, 14) between the paper (11) and the metal layer (16) and/or incorporated into the printable coating (18) applied on top of the metal layer (16). The grease resistant metallized paper may be used in labeling and packaging where grease and oil resistance are needed. Specifically, the metallized paper may be used in packaging for pet food bags of varying constructions and styles or it may be used in packaging chocolate. It may also be used in labels on industrial and consumer products where grease resistance is required.
