摘要:
A water-soluble film for packaging a non-liquid product is disclosed. The film is made from a hydrolyzed copolymer of vinyl acetate and methyl acrylate in the range of from about 30 to about 95 percent by weight, modified starch in the range of from about 8 to about 30 percent by weight, plasticizer in the range of from about 5 to about 30 percent by weight, lubricant/release agent in the range of from about 0.0 to about 1.5 percent by weight, and surfactant in the range of from about 0.01 to about 1.5 percent by weight. The increased starch content of the resultant film lowers production cost, but creates physical incompatibilities for use with liquid products.
