A multi-layer formed, opaque to semitransparent pharmaceutical and food packaging blister container comprising a substrate of 100 to 1000 microns thickness of food grade polyvinyl chloride [PVC], and a metallized layer of thickness 0.005 to 2 microns provided at least on one side of the said substrate and optionally one food and pharmaceutical grade organic layer provided at least on one side of the substrate, having opacity in the range of between 100 to 10 % with improved moisture barrier and resistance to photo degradation properties as compared to a non metallized container, leading to the allowing of a better visual inspection abilities in comparison to a completely opaque formed container system with improved characteristics. |
