ABSTRACT:
A flexible package having an integrated reclose strip, and method for manufacturing same, constructed by modification to existing vertical form and fill packaging machines. The reclose strip comprises a length of tacky two-sided adhesive tape. The apparatus for applying a reclose strip is incorporated into the mechanism which supplies the continuous sheet of packaging material to the vertical form, fill, and seal machine. The invention involves producing a pillow pouch or vertical stand-up pouch having an integrated reclose strip from a single sheet of packaging film. In one aspect, the reclose strip comprises a release liner on one side after package formation. In one aspect, the reclose strip comprises no release liner and is attached along the longitudinal axis of the sheet of packaging material such that the reclose strip is disposed in a channel or recess in the fill tube. The reclose strip permits the package to be reclosed after initial opening without folding the package.
