Zusammenfassung:	A water-soluble film for packaging a non-liquid product, a package employing the film, and methods of making the same, are disclosed. The film is made from a hydrolyzed copolymer of vinyl acetate and methyl acrylate in a range of from about 30 to about 95 percent by weight, modified starch in a range of from about 4 to about 30 percent by weight, plasticizer in a range of from about 5 to about 30 percent by weight, lubricant/release agent in a range of from about 0.0 to about 1.5 percent by weight, and surfactant in a range of from about 0.01 to about 1.5 percent by weight. L'invention concerne un film soluble dans l'eau permettant de conditionner un produit non liquide, un conditionnement employant ledit film, et des procédés de production de ce dernier. Ledit film comprend: un copolymère hydrolysé d'acétate de vinyle et d'acrylate de méthyle dans la plage comprise entre environ 30 et environ 95 pour cent en poids, de l'amidon modifié dans la plage comprise entre environ 4 et environ 30 pour cent en poids, un plastifiant dans la plage comprise entre environ 5 et environ 30 pour cent en poids, un lubrifiant/agent de libération dans la plage comprise entre environ 0,0 et environ 1,5 pour cent en poids, et un tensioactif dans la plage comprise entre environ 0,01 et environ 1,5 pour cent en poids.
