Abstract
A reclosable pouch includes interlocking male and female closure elements having elongate hollow closure profiles. The male closure profile has a hollow shaft section, and the female closure profile has a channel with at least one hollow side. Alternatively, a set of hollow male closure profiles may also form one or more female closure profiles therebetween. A set of pleated grip strips may be disposed adjacent the closure elements to aid in opening a pouch. The closure elements and grip strips may be integral with pouch sidewalls, may be secured and/or separately extruded on to, for example, a polymer, directly to pouch sidewalls, or may be secured to backing strips to form a closure strip, which may subsequently be secured to pouch sidewalls.
