摘要: A novel coated sheet material is made by: (a) coating a porous substrate sheet material with a barrier coating comprised of (i) a cross-linkable polymer resistant to penetration by water moister when cured, and (ii) a water-dispersible, film-forming polymer that is resistant to penetration by grease and oil when cured, said barrier coating composition forming a barrier layer on said substrate sheet material; and (b) coating said barrier layer with a release coating composition. The coated sheet material may be used to make containers, wrappers and/or receptacles for food and other substances, including ovenable and dual-ovenable embodiments thereof.
