摘要： Generally speaking, the present invention is a water-soluble copolymer film comprising a hydrolyzed copolymer of vinyl acetate and a second monomer, the resultant polyvinyl alcohol copolymer having a degree of hydrolysis, expressed as a percentage of vinyl acetate units converted to vinyl alcohol units, of from about 90% to 100%. The second monomer is preferably selected from the group of monomers having carboxylate functionality or sulfonate functionality. The resulting water-soluble copolymer film is disclosed for use in making pouches to contain a unit dose of liquid detergent, such as a liquid laundry detergent. However, it is an aspect of the copolymer film that film solubility is not significantly affected adversely by the detergent. Such film produces pouches having a greater storage shelf-life over prior art water-soluble film.
摘要翻译：一般而言，本发明是包含乙酸乙烯酯和第二单体的水解共聚物的水溶性共聚物膜，得到的聚乙烯醇共聚物具有水解度，以乙酸乙烯酯单元转化为乙烯醇单元的百分比表示，为约90％至100％。第二单体优选选自具有羧酸酯官能团或磺酸酯官能团的单体组。所公开的所得水溶性共聚物膜用于制造袋以包含单位剂量的液体洗涤剂，例如液体衣物洗涤剂。然而，共聚物膜的一个方面是膜的溶解度不会受洗涤剂的不利影响。这种膜产生比现有技术的水溶性膜更大的储存保质期的袋。

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.
