Abstract
An aqueous paper barrier coating and methods for improving barrier properties of packaging material are described. The packaging material includes a substrate with coatings to provide a packaging material having tailored moisture vapor transmission, oxygen permeation or transmission, oil and grease resistance, and light properties.
Claims20
A substrate having improved barrier properties comprising:
- a) a substrate having an outermost surface and an innermost surface disposed opposite one another;
- b) an optional primer coating layer disposed on and in direct contact with the outermost, innermost, or both surfaces of the substrate;
- c) a biodegradable coating layer comprising at least one biodegradable polymeric emulsion, disposed on and in direct contact with the outermost surface, the innermost surface, or both surfaces of the substrate or optional primer coating layer;
- d) optionally, one or more polymeric coatings disposed on the surface of the biodegradable coating layer;
- and
- e) a topcoat layer comprising one or more polymeric emulsions, and optionally one or more wax emulsions, disposed on the surface of the biodegradable coating layer or optional polymeric coating disposed on the surface of the biodegradable coating.

A method of providing improved barrier properties of a substrate comprising:
- a) providing a substrate having an outermost surface and an innermost surface disposed opposite one another;
- b) optionally applying a primer coating layer disposed on and in direct contact with the outermost surface, the innermost surface, or both surfaces of the substrate;
- c) applying a biodegradable coating layer comprising at least one biodegradable polymeric emulsion, disposed on and in direct contact with the outermost surface, the innermost surface, or both surfaces of the substrate or optional primer coating layer;
- d) optionally applying one or more polymeric coatings disposed on the surface of the biodegradable coating layer;
- and
- e) applying a topcoat layer comprising one or more polymeric emulsions, and optionally, one or more wax emulsions, disposed on the surface of the biodegradable coating layer or optional polymeric coating disposed on the surface of the biodegradable coating.
