Abstract: A series of interconnected bags (3) and a method and apparatus for the manufacturing and charging thereof. A series of bags (3) are blow formed from plastics film tube (5) which integrally incorporates the recloseable elements (6) adjacent what will become a top (8) of each bag (3). The plastic film tube (5) is longitudinally slit opposite the recloseable elements (6) to provide connecting strips (12) extending along each side of what also becomes open bottoms (10) of the bags (3). Support rails (7) are provided, preferably integrally, on each strip (12). The recloseable elements (6) are engaged with one another prior to transverse seals (13) and severing cuts (14) being formed at bag forming intervals along the film material (5). The seals (13) and cuts (14) extend from the tops (8) of the bags (3) to the strips (12). The engaged recloseable elements (6) are thus enclosed and cutting the top (8) of a bag (3) is necessary to access the recloseable elements (6).

Abstract: The invention comprises a method of manufacturing a series of bottom opened interconnecting bags having engageable reclosing elements. The method comprises the steps of blow forming a tube of parent bags forming material so that the tube incorporates reclosable elements adjacent what will become a top of the bag. Also formed substantially opposite the reclosable elements and bordering what will become the bottom of the bag is a section which will form strips connecting the bags. The reclosable elements are connected together either before or after slitting the tube longitudinally along the connecting strip forming section to form a connecting strip to each side thereof and applying at bag forming intervals transversely disposed heat seals with associated severing extending across the parent material except for the connecting strips.
