Method for depositing a barrier coating on a plastic substrate

The invention is a method of depositing a barrier coating on the surface of a plastic substrate in a previously evacuated chamber. The multi-layer barrier coating is useful for providing an effective barrier against gas permeability in containers and for extending shelf-life of containers, especiall...
