<p>Disposable bags e.g. bags for use in refuse bins, have a detachably connected closure strip forming a unit with the bag. Specif the closure strip is defined between one edge of the bag and a weakened zone, extends around the periphery of the bag, and consists of the same material as the bag esp. polyethylene or polypropylene. The weakened, tearable zone consists of a series of perforations. The closure strip remains attached to the bag until required for closing the latter.</p> |
