Methods for mounting a slider device on a recloseable package include mounting the slider device by expanding the leg construction of the slider device with an expanding track to allow mounting of the slider on a recloseable zipper construction. A particular method includes providing a slider device to a slider positioner, such as a carousel, moving the slider along an expanding track, and mounting the expanded slider device onto the recloseable mechanism at the end of the track.

Method and apparatus for application of slider mechanism to recloseable flexible packaging

A recloseable package having recloseable profile strips with a heat barrier is disclosed. The profile strips have flange elements and recloseable , mated profile strips. The package is made by providing mated top and bottom profile strips, providing top and bottom package films on opposite sides of the mated strips and applying heat and pressure to the films adjacent the flanges sufficient to simultaneously form heat seals respectively between the top film and the top profile strip flange and between the bottom film and bottom profile strip flange. The heat barrier may comprise a thickened flange element, buffer strip or a coextrusion of high temperature resin on the inside layer of the flange element. The heat barrier prevents the flanges from fusing together during the formation of flange-film seals.

Recloseable package having recloseable profile strips with a heat barrier

A method of forming a recloseable package using special profile strips, the strips themselves and a resulting package are disclosed. The profile strips have a flange element and a recloseable means element, and two mated profile strips are provided with a heat barrier means. The method comprises the steps of providing mated top and bottom profile strips, providing top and bottom package films on opposite sides of the mated strips and applying heat and pressure to the films adjacent the flanges sufficient to simultaneously form heat seals respectively between the top film and the top profile strip flange and between the bottom film and bottom profile strip flange. The heat barrier means may comprise a thickened flange element, buffer strip or a coextrusion of high temperature resin on the inside layer of the flange element. The heat barrier means prevents the flanges from fusing together during the formation of flange-film seals.
