Title
(EN) PVP COPOLYMER FOR HARSH CHEMICAL PACKAGING
(FR) COPOLYMÈRE DE PVP POUR L'EMBALLAGE D'UN PRODUIT CHIMIQUE AGRESSIF
Abstract
(EN)
A water soluble film useful in unit-dose chemical packaging is disclosed. The film may include: a water soluble saccharide and a polyvinyl alcohol copolymer consisting essentially of: (a) from 80 to 99 mole percent of vinyl alcohol and vinyl ester monomer; and (b) from 1 to 20 mole percent of a pyrrolidone comonomer. Such compositions may be used to provide a water-soluble film simultaneously satisfying requirements in regard to water solubility, biodegradability, and physical properties, even when used for packaging a broad range of harsh, oxidizing chemicals.
(FR)
L'invention concerne un film hydrosoluble utile dans un emballage de produit chimique à dose unitaire. Le film peut comprendre : un saccharide hydrosoluble et un copolymère d'alcool polyvinylique consistant essentiellement en : (a) de 80 à 99 pour cent en moles de monomère d'alcool vinylique et d'ester vinylique; et (b) de 1 à 20 pour cent en moles d'un comonomère de pyrrolidone. De telles compositions peuvent être utilisées pour fournir un film hydrosoluble satisfaisant simultanément aux exigences vis-à-vis de la solubilité dans l'eau, de la biodégradabilité et des propriétés physiques, même lorsqu'il est utilisé pour emballer une large gamme de produits chimiques oxydants agressifs.
