A multi layer composite having oil and grease resistance comprising: a)
a paper or paperboard substrate, b) a base coat on a surface of said
substrate comprising a first polymer selected from the group consisting
of film forming natural and synthetic polymers in the substantial absence
of a mineral pigment filler, and c) a top coat on a surface of said base
coat, said top coat comprising a continuous polymer phase comprising one
or more film forming synthetic polymers having dispersed therein at least
one platy mineral pigment and at least one non-platy mineral pigment.
This invention also relates to a method of making the composite and
articles of manufacture fabricated totally or in part from the composite
of this invention where oil and grease resistance is required or desired,
such as container, bags and wraps for packaging oily or greasy materials
such as animal and human food.
