Abstract
(EN)
This laminate is provided with a polyethylene-based first film, a gas barrier film, and a polyolefin-based second film in this order. The gas barrier film is a dried coating of a coating composition containing a main agent and a curing agent containing a water-dispersible polyisocyanate, the main agent containing a polyurethane dispersion containing a polyurethane resin which is a reaction product of an isocyanate group-terminated prepolymer and a chain extender, the prepolymer being a reaction product of a polyisocyanate component and a polyol component containing a C2-6 diol and an active hydrogen group-containing compound containing a hydrophilic group. The dried coating has a mass per unit area of 0.5 to 2.5 g/m2.

L'invention concerne un stratifié pourvu d'un premier film à base de polyéthylène, d'un film barrière aux gaz et d'un second film à base de polyoléfine, dans cet ordre. Le film barrière aux gaz est un revêtement séché d'une composition de revêtement contenant un agent principal et un agent de durcissement contenant un polyisocyanate hydrodispersable, l'agent principal contenant une dispersion de polyuréthane contenant une résine de polyuréthane qui est un produit de réaction d'un prépolymère à terminaison de groupe isocyanate et d'un allongeur de chaîne, le prépolymère étant un produit de réaction d'un composant polyisocyanate et d'un composant polyol contenant un diol en C2-6 et un composé contenant un groupe hydrogène actif contenant un groupe hydrophile. Le revêtement séché présente une masse surfacique comprise entre 0,5 et 2,5 g/m2.
