Recyclable and repulpable ream wrap and related methods of manufacture

This invention generally relates to recyclable and repulpable coated paper stocks and related methods of making the same useful as packages, containers or labels having water resistance, grease resistance and moisture vapor barrier characteristics. More particularly, it concerns coated paper stocks, preferably for use as ream wrap, comprised of a substrate coated on at least one surface with a base coat and at least one additional coat over said base coat both of which are applied as wax free water based polymeric dispersions. The water based dispersion coatings are repulped and recycled more readily than conventional polyethylene or wax coatings. Recyclable and repulpable coated paper stock, preferably for use as ream wrap, comprising a substrate coated on at least one surface with a base coat and at least one additional coat over said base coat. Both coats are water based dispersions of a polymer selected from the group consisting of acrylic polymers, acrylic copolymers, polyvinyl acetate, polyvinyl alcohol, ethylene-vinyl acetate, polyvinyl chloride, styrene butadiene copolymers, polyvinylidiene chloride and its copolymers, or starch. The wax free coating forms a pin-hole free continuous film on the substrate which is resistant to water and water vapor. The invention also includes processes for making and recycling the invented coated paper stocks.
