Abstract
Methods and apparatus for making reclosable packages having slider-actuated string zippers. More specifically, the apparatus is a form-fill-seal machine having means for placing product on a web of packaging film; means for forming a receptacle having an interior volume and a mouth, with the product in the interior volume and a string zipper installed in the mouth, the web of packaging film forming at least one wall of the receptacle; a slider insertion device for inserting sliders on the string zipper; and means for sealing the receptacle so that ambient air cannot enter the interior volume. The form-fill-seal machine may further include either means for aligning an edge of the web with a flangeless zipper strip of the zipper strip before the web is joined to the flangeless zipper strip or means for trimming an edge of the web after a portion of the web proximal to the edge has been joined to a flangeless zipper strip of the string zipper.
