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). The support rails (7) enable the bags (3) to be suspended bottom (10) uppermost and conveyed through a charging and sealing apparatus. Following charging the strips (12) are removed to separate the bags (3) therefrom and from one another.
