Disclosed are articles useful as the body of a container for containing gas under pressure, and containers which comprise the articles to which are affixed valves to control the flow of gas out of the container, wherein the articles comprise a hollow container body, having an external surface and having an opening through which gas can enter or leave the interior of the hollow container body; optionally but preferably a layer of fiber-reinforced polymer around the exterior of the container body, and an external layer of elastomer around and sealed to the external surface of the layer of fiber-reinforced polymer if present or else to the cylinder body.

The aim of the invention is to provide polyester/primer/metallic coating composite films having good adherence of the metallic coating in dry and humid conditions. Said films also form a good gas barrier: oxygen permeability less than or equal to 0.8 cc/m2/d; water vapour permeability less than or equal to 0.3 g/m2/d. To this end, the invention concerns a composite film comprising a polyester substrate, at least one coating adhering on at least one of the faces of the substrate and at least one layer of primer for cross-linked adhesion between the substrate and the coating. Said primer comprises at least one acrylic and/or methacrylic polymer P1, at least one acrylic and/or methacrylic polymer P2 different from P1, at least one cross-linking agent, and, preferably, at least one polyester that is soluble or dispersible in water: P1 having a gel content TG1>70% by dry weight with respect to P1; P2 having a gel content TG2TG1 and 20% by dry weight, with respect to P2; P1 having a surface-grafted free weak acid content >0.8 in meq/g of polymer; [P2]60% by weight on dry by weight in respect to P1+P2. The method for producing said film, the adhering primer, and the articles obtained using said film, also form part of the present invention.

The present invention relates to a method of forming a foam material, the method comprising the steps of: a) providing an aqueous dispersion comprising polymer particles and a functional filler dispersed in the aqueous phase, and b) lyophilising the aqueous dispersion, to thereby form the foam material.
