A semi-aqueous ethylene-vinyl alcohol coating composition that is a stable, homogeneous solution which is capable of being easily applied to a substrate to form a multi-layer structure at room temperature, by spray, rod, gravure, or other mechanical means. Upon evaporation of the volatile components, this coating solution leaves a clear, homogeneous film comprising EVOH. The film resists degradation and discoloration during the lifetime of the structure, and upon incineration or recycling does not evolve harmful acids into the environment. |
