A flexible printable multilayer structure for use as an advertising display, a banner, or as a cover for vehicles, building facades, structures, luggage or the like, is composed of substantially halogen-free materials and comprises: a substrate layer of paper, board, polymeric film or woven or non-woven fabric; a substantially impermeable intermediate layer of an ethylene copolymer at least on one face of the substrate layer; and an outer layer of a thermoplastic hydrophilic polymer on the intermediate layer(s). The outer layer of the thermoplastic hydrophilic polymer has a permeability corresponding to an MVTR (moisture vapor transmission rate) of 1,000-20,000 g/m<SUP>2</SUP>/day measured according to ASTM 96BW and a thickness t from 5 to 50 mum. The intermediate layer has a thickness T from 50 to 500 mum.
