A method for increasing the adhesion of a first layer comprising fluoropolymer to a second layer comprising a melt-processable, substantially non-fluorinated polymer, comprising the steps of (A) mixing an aliphatic di- or polyamine of less than 1,000 molecular weight with a melt-processable composition comprising said substantially non-fluorinated polymer; (B) forming a multi-layer composite comprising a layer comprising the mixture resulting from step A and a layer comprising said fluoropolymer; wherein said two layers are in substantial contact, said fluoropolymer comprises interpolymerized units derived from vinylidene fluoride, said substantially non-fluorinated polymer is a polyamide, polyimide, polyurethane or a carboxyl, anhydride, or imide functional polyolefin, and said di- or polyamine is present in an amount sufficient to increase the adhesion between the two layers compared to composites prepared without said di- or polyamine.
