The heat sealing jaw may be suitable for forming an easy-open feature on a. packaging pouch used to contain flowable material. In certain embodiments the heat sealing jaw comprises a jaw body, a heat sealing element secured to the jaw body, a support surface for clamping the layers of film together against the opposing backing jaw, and, a heat sink coupled to the heat sealing element for inducing a temperature gradient along a sealing face of the heat sealing element. The sealing face may have a protrusion for forming a notch within the layers of film. Related apparatuses and methods are also described.
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.

An improved piercing fitment assembly for mounting to a flexible container is provided, whereby the contents of the container are dispensed by piercing a pierceable portion of a cap using a fluid transfer device. The piercing fitment assembly is easy to use as a relatively minimal amount of force is required for piercing and establishing fluid transfer. It also has a locking system which locks the fluid transfer device into a dispensing state and also forms a reliable seal between the cap and the fluid transfer device which minimizes the risk of unwanted spillage. The fitment assembly comprises: a spout connected in fluid communication to the container; a cap having a pierceable portion sealing an end of the spout and a fluid transfer device having a leading tooth to initiate piercing of the pierceable portion of the cap.
