Abstract
A coated substrate for packaging material that reduces material to the landfill, is compliant for recycling and compostability, and/or enhances Water Vapor Transmission Rate (WVTR). The coated substrate includes a substrate, a barrier coating and an ink layer disposed on the barrier coating. The barrier coating includes a polymeric matrix material and nanoparticles. The barrier coating provides a water vapor transmission rate through the coated substrate lower than the water vapor transmission rate of a substrate having no barrier coating.
Claims18
A coated substrate for packaging material comprising:
- a substrate;
- a barrier coating comprising:
- a polymeric matrix material;
- and
- nanoparticles;
- an ink layer disposed on the barrier coating;
- wherein the barrier coating provides a water vapor transmission rate through the coated substrate lower than the water vapor transmission rate of a substrate having no barrier coating.
A package comprising:
- a package body including a substrate, the substrate having a coating comprising:
- a matrix material including a polymer;
- and
- nanoparticles;
- wherein the barrier coating provides a water vapor transmission rate through the coated substrate lower than the water vapor transmission rate of a substrate having no barrier coating.
A method of forming a coated substrate for packaging material, the method comprising:
- providing a substrate;
- applying a barrier coating to the substrate, the barrier coating comprising:
- a polymeric matrix material including a polymer;
- and
- nanoparticles;
- applying an ink layer to the barrier coating;
- wherein the barrier coating provides a water vapor transmission rate through the coated substrate lower than the water vapor transmission rate of a substrate having no barrier coating.
