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 TG2≤TG1 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 provides a laminate material having a polyester film and a web of polyester fibers cohesively bonded directly thereto, such that portions of the fibers are bonded to the polyester film and portions of the fibers are free from the polyester film. The invention may also include a glass reinforced polymer layer formed on the laminated facer where the polymer of the glass reinforced polymer layer is commingled with the nonwoven of the laminated facer. The laminate may further include a second polymer layer having a thickness joined to the fiber layer and/or a layer of hot melt adhesive applied to the polyester fibers. Also presented is a composite material having a polyester film, a layer of polyester fibers bonded to the second polymer layer; a second polymer layer joined to the polyester film; and a glass reinforced polymer layer formed on the laminated facer, where the polymer of the class reinforced polymer layer is commingled with the nonwoven of the laminated facer.
