摘要:
Provided is a water dispersible polymer film that is useful as an encasing material for detergent packets. The water dispersible polymer film comprises: a polyvinyl alcohol substrate; and a barrier layer coated on at least one surface of the substrate, each barrier layer independently comprising (a) a first copolymer that is an at least partially neutralized maleic anhydride-C2-C8 olefin copolymer or its maleic acid counterpart; or (b) a second copolymer that is an at least partially neutralized ethylene (meth)acrylic acid copolymer, or (c) a mixture of the first copolymer and the second copolymer.
