Abstract:
The barrier properties of a water soluble gas barrier material are improved if the material is blended with a nanoparticle calcium carbonate having a size of from 10 to 250 nanometers. The barrier material is on a substrate to provide a substrate with gas barrier properties. A layer of heat sealable material may be applied to the exposed surface of the barrier material. A method for making the barrier coated substrate is disclosed.
