FLEXIBLE FILM LAMINATES Abstract A flexible film laminate comprises a first layer of a polyacrylonitrile homopolymer film; a second layer joined at one surface to the first layer and composed of (i) a polyacrylonitrile homopolymer film or (ii) a heat-sealable polyolefin film contacted at said one surface by an adhesive in the form of a maleic acid anhydride adduct of an ethylene-propylene copolymer; and an adhesive third layer joining said first and second layers. The adhesive of the third layer is a combination of a styrene-butadiene block copolymer and a random terpolymer of from 30 to 40 parts by weight of 1,3-pentadiene; 30 to 40 parts by weight of a monocyclic terpene; and from 25 to 35 parts by weight of alpha-methylstyrene, said combination consisting of from 1 to 3 parts by weight of the block copolymer to from 3 to 1 parts by weight of the terpolymer. The first and second layers are bonded together by way of the adhesive(s) and the laminate is subjected to ultraviolet radiation through the first layer during bonding to increase the final bond strength.
