A thermoplastic, multilayer film suitable for use in water packaging comprises at least a gas-barrier layer, and an innermost surface, heat- sealable, layer, wherein said heat-sealable layer essentially consists of a homogeneous single-site catalysed copolymer of ethylene and an a-olefin having from four to eighteen carbon atoms. Storing water in flexible containers, e.g. bags or pouches, made from such a film would reduce the room required for storage while maintaining the taste of the packaged water unaltered for long periods of time.
