Abstract
Methods and apparatus for low-cost manufacture of reclosable packages having slider-operated zippers. One method of manufacture comprising the following steps: (a) joining film material to a back side of a first flangeless zipper strip having a first closure profile on its front side; (b) joining film material to a back side of a second flangeless zipper strip having a second closure profile on its front side, the first and second closure profiles of the first and second zipper strips being interlockable to form a string zipper assembly; and (c) loading a slider comprising a plow onto an open section of the string zipper assembly with the plow being inserted between the first and second flangeless zipper strips. Respective portions of the first and second portions of film are respectively disposed between the slider and the string zipper assembly when the slider is loaded. This method further comprises the step of trimming a marginal portion of the film material that extends beyond the portion of film material joined to the back side of either of the first flangeless zipper strip.
