Abstract: A packaging apparatus includes a control unit, a loading station that positions a tubular film around a product to be packaged, a sealing station, a control unit that controls the sealing station to create one or more seals on the tubular film, an evacuation assembly that includes a first member and a second member arranged opposite the first member, and a means for moving the product relative to and from the evacuation assembly. The first member includes a deformable portion. The first and second members are relatively movable between: a first configuration, in which the first and second members are spaced apart from one another, a second configuration, in which the deformable portion contacts at least part of the second member and/or part of the tubular film, and a third configuration in which the deformable portion is compressed in a compression direction towards the second member.

Abstract: A form-fill-seal machine has an ultrasonic vibration emitter head 11 positioned outside the tube being formed by the overlapping of the margins 3 and 5 of a film web, and an anvil 13 positioned inside the tube defined by those margins, the anvil being mounted on an anvil carrier 25 which is supported by a frame element entirely independent of the forming box 1 used to fold the film, so as to isolate the anvil from vibrations sustained from the forming box. The anvil carrier can be mounted directly to a carrier body for the ultrasonic vibration emitter, and preferably has the shape of an inverted letter J where the anvil is positioned near the toe 25a of the J, the mounting to the sealing machine frame is at the top of the stem 25c of the J, with a slot 25b between the toe 25a and the stem 25c.
