Title
(EN) FLEXIBLE FILM FLUID-DISPENSING LINER MEMBER
(FR) ÉLÉMENT DE REVÊTEMENT DE DISTRIBUTION DE FLUIDE EN FILM SOUPLE
Abstract
(EN)
A multilayer flexible film fluid-dispensing liner member useful for making a dispensing device, the multilayer flexible film fluid-dispensing liner member including: (a) at least a first film substrate layer; and (b) at least a second film substrate layer; wherein at least a portion of the first film substrate layer is bonded to the second film substrate layer forming the multilayer flexible film member; and (c) at least one duct having at least one inlet and a plurality of outlets, the at least one duct being disposed between the first and second substrate layers for forming a path for a fluid to pass from the at least one inlet of the duct to the plurality of outlets of the duct; wherein the first and second substrate layers of the multilayer flexible film fluid-dispensing liner member are constructed of a material that is flexible; and wherein the multilayer flexible film fluid-dispensing liner member has a flexibility property of from 3.6e-10 Nm to 2 Nm; and a process of manufacturing the multilayer flexible film member.
