Heat-sealable plastic strip (100) can be separated into individual strips (1), each of which forms a bag (T) with a sealing flap (V). A strip of permanently adhesive material (5) is applied to the upper side of the plastic strip. A strip of non-stick material on the underside covers this when the strip is rolled up. An Independent claim is included for a bag in which the sealing flap is connected to it by a line of perforations. |
