Abstract: Composite membrane materials and process for their production. The process entails the use of at least first and second porous membranes formed of a polymeric material and at least a third porous membrane formed of the same polymeric material, but having larger pores than the first and second porous membranes. The first, second and third porous membranes are laminated together by applying heat and pressure to the first, second and third porous membranes without applying a separate adhesive material therebetween. The laminated first, second and third porous membranes form a composite membrane in which the third porous membrane is between the first and second porous membranes.
