ABSTRACT:
A resilient backing member for use in cooperation with an impulse heating element comprises a resilient body having a longitudinal shoulder surface and a longitudinal intermittent raised edge protruding from the shoulder surface. The resilient backing member is for use in cooperation with an impulse heating element for sealing layers of thermoplastic film together and for either forming a sealed portion on the film, a rupturable portion on the film or severing the film. Accordingly, the resilient backing member can be used on a pouch filling machine to produce a string of sealed pouches connected by a rupturable portion or a sealed portion, and filled with flowable material without the use of a separate cutting blade.
