Abstract
A method and apparatus of forming a reclosable bag of flexible film wherein the bag has confronting side walls joined by seams at its edges and confronting rib and groove fastener strips at the top edge with the strips joined to the inner faces of the bag walls by bonding layers which have a predetermined width such that when a spot seal is formed at the ends of the strips, leakage is prevented between said strip ends so that the interconnecting profiles of the strips are sealed in permanent alignment. The flattened melted material of the spot seals is secured to the bag walls by the bonding layer and the predetermined width of the bonding layer is wider than the spot seals.
