摘要:
An improved reclosable bag structure such as formed out of plastic film or laminations thereof with front and back wall panels attached at their bottom and side edges and reclosable rib and groove profile fastener strips along the inner surface of the panels at the bag top with at least one of the strips secured by a layer of bonding element that has a limited area to secure the fastener strip only at its upper edge at a location above the profile or alternatively the strip uses a bond preventing element that permits only the upper edge of said strip to be secured to said panel at a location above the profile with this manner of securing accommodating outward movement of the film panel to apply a force on the strips in a shear rather than a peel mode.
