Abstract
Compositions including a fabric layer with a water-insoluble polymer impregnated into the fabric layer to provide sheets are described. In particular, the sheet composites have a permeability to oxygen in the direction perpendicular to the sheet that is less than one-tenth the transmission rate for the fabric layer alone and less than one-fifth the transmission rate for the polymer alone without the fabric layer.
