Abstract
The stability of polyvinyl films used to contain detersive systems may be enhanced by the use of a barrier coating composition to separate the film degrading components, i.e., acids, bases, and halogens, from these films. The barrier coatings may either encapsulate the individual film degrading components, or they may coat the entire detersive system.
