Reclosable bag formed on form, fill and seal machine

Abstract

A reclosable bag made on a form, fill and seal machine by a method which includes the steps of: applying an adhesive strip of material to a web of bag material to extend transversely relative to longitudinal edges of the web, the adhesive strip including a front surface releasably applied to the web via a pressure-sensitive adhesive and an exposed rear surface; folding the web about an axis extending parallel to the longitudinal edges thereof; and then sealing the web to form the bag, including permanently sealing a portion of the web to the exposed rear surface of the adhesive strip to form a reclosable end seal. Another method includes the steps of: forming an opening location in a web of bag material having a length extending generally between longitudinal edges of the web; applying an adhesive strip to the web over the opening location, the adhesive strip including a front surface releasably applied to the web via a pressure-sensitive adhesive and an exposed rear surface, the front surface extending to opposite lateral sides of the transversely extending opening location; folding the web about an axis extending parallel to the longitudinal edges; and sealing the web to form the reclosable bag, including permanently sealing a portion of the web to the exposed rear surface of the adhesive strip and a portion of the web to the front surface of the adhesive strip, but only to one lateral side of the opening location.
