ABSTRACT:
The present invention is directed to a film suitable for packaging medical solutions and other pH sensitive products. Product pH is controlled by including an ionomer resin blended with a vinyl carboxylate copolymer in a film layer or adhesive. Alternatively, the ionomer may be present as either a core layer, strength layer, or other distinct layer positioned between the sealant layer and the vinyl carboxylate copolymer containing layer.
