A variety of spine-shapes are disclosed including straight, T-shaped and curved spines. An installation machine is also disclosed for formation of and heat- or adhesive-application of the spines to the recloseable self-sealing bag material either prior to or during the filling and sealing process. The present invention=s design is simple and straightforward, highly effective, and can be economically manufactured.
