Title (EN) GAS BARRIER FILM AND PROCESS FOR PRODUCING THE SAME
(FR) FILM FORMANT BARRIERE AUX GAZ ET PROCEDE DE PRODUCTION ASSOCIE
Abstract: front page image
(EN)A film with gas barrier properties which comprises a thermoplastic resin film and formed on at least one side thereof a coating layer comprising a vinyl polymer (A) comprising at least 40 mol% vinyl alcohol units and a vinyl polymer (B) comprising at least 10 mol% maleic acid units. The (A)/(B) weight ratio is from 97/3 to 20/80. The coating layer has a coefficient of oxygen permeability of 500 ml. $g(m)m/m?2¿/day/MPa or lower. This film has high gas barrier properties even under high-humidity conditions.
(FR)Ce film possédant des propriétés de barrière aux gaz comprend un film de résine thermoplastique sur un côté duquel au moins on a formé une couche de revêtement comprenant un polymère vinylique (A) se composant d'au moins 40 moles % d'unités d'alcool vinylique, et un polymère vinylique (B) se composant d'au moins 10 moles % d'unités d'acide maléique, le rapport pondéral entre (A) et (B) étant compris entre 97/3 et 20/80. La couche de revêtement possède un coefficient de perméabilité à l'oxygène de l'ordre de 500 ml. $g(m)m/m?2¿/jour/MPa ou moins. Ce film possède de très bonnes propriétés de barrière aux gaz, même dans des conditions de forte humidité.
