A method of making packages having a reclosable zipper construction openable and closeable by a slider device by a horizontal form, fill and seal process. The method includes applying the slider device to the zipper construction prior to incorporating the zipper construction with the package film to form the package. The zipper construction is first applied and adhered to one half of the package film and then to the other half. A tamper-evident seal may be provided encasing the slider device to provide indication whether access has been gained to the slider device and the interior of the package.

1. A method of making and filling a reclosable package comprising a zipper closure and a slider device, the method comprising:(a) providing a closure construction having a first closure profile and a second closure profile, the closure construction having a length approximately equal to the package
1. A method of making and filling a reclosable package comprising a zipper closure and a slider device, the method comprising:(a) providing a closure construction having a first closure profile and a second closure profile, the closure construction having a length approximately equal to the package width;(b) providing a slider device constructed and arranged for mounting on the closure construction and for interlocking the first closure profile with the second closure profile when the slider device is moved in a first direction, and for disengaging the first closure profile from the second closure profile when the slider device is moved in a second opposite direction;(c) mounting the slider device onto the closure construction;(d) attaching the closure construction with the slider device mounted thereon transversely across a first half of a film web;(e) attaching the closure construction with the slider device mounted thereon transversely across a second half of the film web;(f) forming a first side edge, a bottom edge, and a top edge, the top edge proximate to the closure construction with the slider mounted thereon and opposite to the bottom edge, and leaving unsealed an open side edge adjacent the top edge and the bottom edge and opposite the first side edge;(g) filling the resealable package through the open side edge with an item; and(h) forming a second side edge to seal the open side edge after filling, the second side edge connecting the bottom edge and the top edge. 2. The method according to claim 1, further comprising, between the step of attaching the closure construction with the slider device mounted thereon to a first half of a film web and the step of attaching the closure construction with the slider device mounted thereon to a second half of the film web:(a) folding the film web along a centerline. 3. The method according to claim 1, wherein the step of mounting the slider device onto the closure construction comprises:(a) punching a notch in the closure construction; and(b) mounting the slider device into the notch of the closure construction. 4. The method according to claim 1, wherein the step forming a first side edge, a bottom edge, and a top edge comprises forming a top edge comprising a tamper-evident structure over the slider device. 5. The method according to claim 1, wherein the step of providing a closure construction having a first closure profile and a second closure profile, the closure construction having a length approximately equal to the package width comprises:(a) cutting an extended length of closure construction to a length approximately equal to the package width. 6. A method of manufacturing a reclosable package comprising a zipper closure construction and a slider device, the reclosable package having a width and the zipper closure extending the width of the package, the method comprising:(a) providing a closure construction having a first closure profile and a second closure profile, the closure construction having a length approximately equal to the package width;(b) providing a slider device constructed and arranged for mounting on the closure construction and for interlocking the first closure profile with the second closure profile when the slider device is moved in a first direction, and for disengaging the first closure profile from the second closure profile when the slider device is moved in a second opposite direction;(c) mounting the slider device onto the close construction;(d) attaching the closure construction with the slider device mounted thereon transversely across a first half of a film web;(e) attaching the closure construction with the slider device mounted thereon transversely across a second half of the film web;(f) forming a first side edge;(g) forming a bottom edge;(h) forming a top edge proximate to the closure construction with the slider device mounted thereon opposite the bottom edge; and(i) leaving unsealed a second side edge until the reclosable package i s filled by a later operation, the second side edge opposite the first side edge and connecting the bottom edge and the top edge. 7. The method according to claim 6, further comprising, between the step of attaching the closure construction with the slider device mounted thereon to a first half of a film web and the step of attaching the closure construction with the slider device mounted thereon to a second half of the film web:(a) folding the film web along a centerline. 8. The method according to claim 6, wherein the step of mounting the slider device onto the closure construction comprises:(a) punching a notch in die closure construction; and(b) mounting the slider device onto the closure construction. 9. The method according to claim 8, wherein the step of punching a notch in the closure construction is done before the step of mounting the slider device onto the closure construction. 10. The method according to claim 6, wherein the step of forming a top edge comprises:(a) providing a tamper-evident structure over the slider device to indicate whether access has been gained to the slider device. 11. The method according to claim 6, wherein the step of providing a tamper-evident structure over the slider device to indicate whether access has been gained to the slider device comprises providing a tamper-evident structure over the slider device by sealing the first half of the film web to the second half of the film web. 12. The method according to claim 11, wherein the step of providing a tamper-evident structure over the slider device by sealing the first half of the film web to the second half of the film web is accomplished simultaneously with the step of attaching the closure construction with the slider device mounted thereon to a second half of the film web. 13. The method according to claim 6, wherein the step of providing a closure construction having a first closure profile and a second closure profile, the closure construction having a length approximately equal to the package width comprises:(a) cutting an extended length of closure construction to a length approximately equal to the package width. 14. The method according to claim 13, wherein the step of cutting an extended length of closure construction to a length approximately equal to the package width is done after the step of mounting the slider device onto the closure construction. 15. The method according to claim 13, wherein prior to the step of cutting an extended length of closure construction to a length approximately equal to the package width, the method comprises:(a) sealing together the first closure profile and the second closure profile of the closure constriction.
