Conventional horizontal form-fill-seal equipment for packaging articles such as cheese can be improved by the use of shrink barrier films. In conjunction with the use of such films, the improvement includes means for supporting the film prior to longitudinally sealing to form a tube, and means for heating sealing elements of transverse impulse type sealing dies for a limited duration, to effect sealing of the tube formed from the film. |
