Title (EN) COATED FILM STRUCTURES WITH AN ALUMINUM OXIDE INTERMEDIATE LAYER
(FR) STRUCTURES DE FILM REVÊTUES COMPRENANT UNE COUCHE INTERMÉDIAIRE D'OXYDE D'ALUMINIUM
Abstract:
(EN) Embodiments of the present disclosure provide a coated film structure including a substrate layer, an overcoat layer, and at least one intermediate layer disposed between the substrate layer and the overcoat layer. The substrate layer includes a polymer film substrate, the overcoat layer includes polyvinyl alcohol, and the at least one intermediate layer includes aluminum oxide. The substrate layer has a thickness from 1 µm to 120 µm and the overcoat layer has a dry coat weight of from about 0.05 g/m2 to about 1.5 g/m2. The coated film structure has an oxygen transmission rate of less than about 0.70 cm3/m2/day at 90% relative humidity and 23°C as measured in accordance with ASTM D3985. Further, the coated film structure has a water vapor transmission rate of less than 1.00 g/m2/day at 90% relative humidity and 37.8°C as measured in accordance with ASTM E-398.
(FR) Des modes de réalisation de la présente invention concernent une structure de film revêtue comprenant une couche de substrat, une couche de revêtement, et au moins une couche intermédiaire disposée entre la couche de substrat et la couche de revêtement. La couche de substrat comprend un substrat de film polymère, la couche de revêtement comprend de l'alcool polyvinylique, et la ou les couches intermédiaires comprennent de l'oxyde d'aluminium. La couche de substrat a une épaisseur de 1 µm à 120 µm et la couche de revêtement a un poids de revêtement sec d'environ 0,05 g/m2 à environ 1,5 g/m2. La structure de film revêtue présente un taux de transmission d'oxygène inférieur à environ 0,70 cm3/m2/jour à 90 % d'humidité relative et à 23 °C tel que mesuré conformément à la norme ASTM D3985. De plus, la structure de film revêtue présente un taux de transmission de vapeur d'eau inférieur à 1,00 g/m2/jour à 90 % d'humidité relative et à 37,8 °C tel que mesuré conformément à la norme ASTM E-398.
