Abstract
A coated substrate and methods of making and using coated substrates, wherein the coated substrate comprises a coating consisting essentially of a layered mineral, a thermoplastic polymeric substrate having pendant groups receptive to said layered mineral, and wherein said pendant groups are coordinated metal groups, or are groups which can be bonded to coordinating cations or anions, or pendant groups directly receptive said layered mineral. The coated substrate is less permeable to gases, such as oxygen and carbon dioxide.
