Title
(EN) POLYVINYL ALCOHOL RESIN COMPOSITION AND MULTILAYER PACKAGES
(FR) COMPOSITION DE RESINE D'ALCOOL POLYVINYLIQUE ET CONTENANTS MULTICOUCHES
Abstract
(EN)
A resin composition having an oxygen-scavenging activity is provided. This composition comprises 70 to 99.9 wt% of a polyvinyl alcohol resin (A) and 0.1 to 30 wt% of a thermoplastic resin (B) other than the resin (A) which bears carbon-carbon double bonds and heteroatom-containing functional groups, and the composition exhibits a rate of oxygen absorption of 0.001 ml/m2 • day or above.
(FR)
L'invention concerne une composition de résine possédant une activité d'élimination de l'oxygène. Cette composition comprend 70 à 99,9 % en poids d'une résine d'alcool polyvinylique (A) et 0,1 à 30 % en poids d'une résine thermoplastique (B) différente de la résine (A), qui possède des liaisons doubles carbone-carbone et des groupes fonctionnels contenant des hétéroatomes. Cette composition possède un taux d'absorption de l'oxygène égal ou supérieur à 0,001 ml/m2 x jour.
