Title
(EN) CROSS-LINKED PVOH COATINGS HAVING ENHANCED BARRIER CHARACTERISTICS
(FR) REVETEMENT EN ALCOOL POLYVINYLIQUE RETICULE A CARACTERISTIQUES DE BARRIERE AMELIOREES
Abstract
(EN)
An improved oxygen barrier layer for coating a substrate, such as a polymeric film. The oxygen barrier is a layer of cross-linked polyvinyl alcohol and glyoxal, which exhibits improved barrier characteristics to the transmission of oxygen. The oxygen barrier is produced by coating a solution of polyvinyl alcohol, glyoxal and tensioactive agent onto at least one side of a substrate adapted for receipt of such solution. The polyvinyl alcohol is thereafter cross-linked in the absence of a catalyst to provide the oxygen barrier.
(FR)
Couche formant une barrière à l'oxygène améliorée destinée à revêtir des substrats tels que des films de polymère et constituée d'une couche d'alcool polyvinylique réticulé et de glyoxal, présentant des caractéristiques supérieures empêchant la transmission de l'oxygène. La barrière est constituée par application d'une solution d'alcool polyvinylique, de glyoxal et d'un tensioactif sur au moins l'une des faces d'un substrat adapté pour recevoir ladite solution. L'alcool polyvinylique est ensuite réticulé sans catalyseur pour former la barrière à l'oxygène.
