Abstract

This invention relates to ovenable and dual-ovenable coated paperboard suitable for use in producing food trays. More particularly, the invention relates to paperboard substrates which have been coated with a water-based release coating composition. Food trays made from such paperboard have superior grease resistance, high temperature resistance, and excellent food release properties--characteristics which make these trays particularly suitable for use in baking applications.
