ABSTRACT:
A gusseted package and method of making same are provided in which the package is formed by folding a first web along first and second, parallel spaced fold lines inwardly of each opposite side edge to produce first and second overlapping portions and then positioning a second web adjacent the first web. The first and second webs are first heat-sealed together at one end and along the sides of the package. Additionally, the inner surface of the first web is heat-sealed to the adjacent facing inner surface of one of each of the first overlapping portions in a reinforcement region spaced inwardly of the other end of the package and extending between the first and second fold lines with a peripheral boundry generally adjacent and parallel to the second fold line. The resulting heat-seal extends over the major portion of the distance between the first and second fold lines. However, the second overlapping portions of the first web are not heat-sealed to the underlying second web beneath the reinforcement region. The first and second webs are also heat-sealed to each other adjacent the other end but inwardly of the reinforcement region to provide reinforced, graspable, unsecured margin portions at the package first end.
