A pouch-like bag (10) has two walls of flexible plastics sealed around their periphery. The walls are preferably laminated with the inner layer of linear low density polyethylene and the outer layer of oriented polypropylene. The bag is provided with an elongate insert (14) capable of self-sealing a transverse puncture and located adjacent to the bag periphery, and peripheral sealed portins of the bag walls outboard of the insert form a tearable tag (11) which, when torn off, exposes a side of the insert which is preferably formed with a notch or groove (15) to guide a needle for penetration transversely through the insert into the bag, e.g. for injecting a drug into the bag. The bag may also have a pair of inward extensions (19) of the peripheral seal (18) defining a passage (20) for guiding an administration needle of a hospital drip feed system into the bag, the passage having a frangible seal (21) at its inner end and being closed by a tearable tag (12) at its outer end. In manufacture of the bag, the insert may be first sealed between plies of the plastics material which are to form the wlls, whereupon the peripheral seal (18) is effected including the formation of the tearable tags. A gap (22) may be left at the top, which is sealed after the bag has been filled through the gap. |
