Abstract:
Embodiments include a coated paper or paperboard with a multilayer coating and methods of forming a coated paper or paperboard with the multilayer coating. The multilayer coating includes a first water vapor barrier layer, a biopolymer barrier layer, and a second water vapor barrier layer and provides the paperboard with improved oil and grease resistant properties, oxygen barrier properties, and water vapor barrier properties.
