HALOGEN-FREE BARRIER CONSTRUCTIONS AND RELATED METHODS

摘要

A halogen-free multi-layer construction configured to reduce the amount of air in an interior of a sealed container. The multi-layer construction includes an adhesive layer in intimate contact with a barrier layer, and in relation to the barrier layer, the adhesive layer is positioned closer towards the interior of the container. The barrier layer includes a highly amorphous vinyl alcohol polymer. The intimate contact between the adhesive layer and the highly amorphous vinyl alcohol polymer in the barrier layer allows the multi-layer construction to reduce the amount of air in the interior of the container. The multi-layer construction includes water-impermeable interior and exterior layers for preventing liquid water and water vapor from negatively affecting the functioning of the barrier layer.
