A packaging apparatus for forming sealed packages filled with a pourable product comprises a delimiting element movably arranged, in use, within a tube and designed to divide the tube in a first space and a second space. The delimiting element is movable along first and second directions opposite one another and substantially parallel to the tube, and between at least a first position and a second position. The delimiting element comprises a main engagement portion configured to abut against a main abutment portion of a gas supply pipe or a filling pipe with the delimiting element being in the first position. The main abutment portion and/or the main engagement portion are designed such that at least one opening and/or at least one channel is present between the main abutment portion and the main engagement portion with the delimiting element being in the first position.

A cyclic packaging process, such as VFFS or HFFS, packages a product with a viscosity of ≥100,000 centipoise without leaving substantial air pockets in the package, by utilizing a means (38) for restricting upstream flow of viscous product in the strand of tubing (24). The result is that packages of uniform weight of the viscous product can be made without substantial air pockets therein, and without having to use metal clips. An apparatus (10) for carrying out the process is disclosed.

The disclosure refers to a packaging device for manufacturing a packaging for a foodstuff. In particular, the packaging may include a trough-shaped lower packaging part and a top film which can be sealed together along their edges by means of a sealing tool of the packaging device. In order to improve a packaging device completely without evacuation or by evacuation in a simple and inexpensive manner with only a slight negative pressure in such a way that sufficient vapor purging is possible and at the same time cooling of the foodstuff before sealing or excessive degassing of the foodstuff does not take place, vapor can be introduced under pressure between the lower packaging part and the top film at at least one vapor entry point before sealing and can be released into the surrounding atmosphere at an outlet point from the packaging.

A molding apparatus for molding an opening device onto a packaging material web comprises at least one mold unit couplable to the packaging material web; and an injection device configured to inject molten polymer into the mold unit. The injection device comprises a cavity configured to receive the molten polymer, an inlet configured to allow for introduction of the molten polymer into the cavity, a first outlet configured to allow for an outflow of a first portion of the molten polymer from the cavity, a first valve element configured to selectively open and close the first outlet, a second outlet configured to allow for an outflow of a second portion of the molten polymer from the cavity, a second valve element configured to selectively open and close the second outlet and a pressurizing unit in fluidic connection with the cavity and configured to pressurize the molten polymer within the cavity.

An assembly for forming bags, having a belt drive for feeding a film at a film speed to a former shoulder to form a tubular film, a set of jaws movable at a jaw speed to engage and seal a tubular film to form a closed bag, and a sensor assembly to provide a volume signal indicative of a volume of the closed bag, wherein the controller is configured to adjust at least one of the film speed and the jaw speed in response to the volume signal.

A package forming unit comprises plural jaw units, each having at least one respective operative assembly for engaging the tube and for at least partially forming the advancing tube, one respective sealing element for at least partially transversally sealing the tube along a transversal sealing band and a pair of interaction tabs for interacting with the tube. Each jaw unit is controllable as a function of the tube filling level in an operative configuration in which the respective operative assembly, the respective sealing element and the respective pair of interaction tabs are controlled in respective active states while advancing along respective operative portions and a partial operative configuration in which the respective sealing element is controlled in the respective active state and the respective operative assembly and/or the respective pair of interaction tabs is/are controlled in a respective inactive state while, in use, advancing along the respective operative portion.
