<p>A device for sealing plastics films, particularly in batch packages (10) comprises a sealing jaw (32) and a sealing surface (33) thereon. In order to avoid the adhesion of residues of the film on the sealing jaw (32) or its sealing surface (34) during sealing of sealable plastics film in packaging technology, the sealing jaw (32) or sealing surface (33) is protected by a cover comprising a polytetrafluoroethylene (sold under the trademark TEFLON) strip (34). This TEFLON strip is so disposed and designed that it may be moved on from time to time relative to the sealing jaw (32) or sealing surface (33), so that unused areas of the TEFLON strip (34) pass into the sealing position to the required extent.</p> |
