A device for sealing packages, including a product feed and a packaging feed for a tubular packaging material; and a method for sealing packages. Such devices are used, for example, as tubular bag machines. The packages can be produced by type for improved recyclability while simultaneously maintaining a high load-bearing capacity of the package closures with the aid of a closure element made of the same material as the rest of the package by welding the closure element and the package in the closure region.

A method for forming sealed partially-filled packages filled with a pourable product comprises at least forming a tube from a web of packaging material, filling the pourable product into the tube for forming a product column within the tube, directing a sterile gas into the product column for forming and/or maintaining a gas cushion within the product column, and forming and transversally sealing the tube, for obtaining the packages containing the pourable product and a gas space formed from a defined volume of the sterile gas originating from the gas cushion.

There is described a packaging apparatus (1) for forming a plurality of sealed packages (2) from a tube (3) of a web of packaging material (4) which is continuously filled with a pourable product. The packaging apparatus comprises a delimiting element (37) arranged, in use, within the tube (3) and being designed to divide the tube (3), in use, into a first space (38) and a second space (39). The packaging apparatus (1) also comprises a sterile gas supply device (43) for pressurizing the isolation chamber and the second space (39) by means of a respectively a first flow of sterile gas and a second flow of sterile gas.

A vertical flow-wrapper, which produces packages, with a frame/housing, at which a form-fill-tube, a longitudinal-sealing means and a cross-sealing means and a cutting means. A method to produce a package from a plane film.

A packaging machine includes a conveying device for advancing a packaging material web at least to a tube forming station at which the web is formed into a tube and for advancing the tube to a tube forming and sealing device to form and longitudinally seal the tube, a tensioning device to control tension of the web and/or of the tube and a control unit to control operation of the packaging machine. The tensioning device has at least one tensioning assembly having at least first and second drive rollers, a first drive motor connected to the first drive roller to rotate the first drive roller and a second drive motor connected to the second drive roller to rotate the second drive roller. The control unit controls the first and second drive motors such that a free loop of the web expands and/or advances between the first and second drive rollers.

A separator assembly for separating adjacent flexible bags in a filling assembly includes a body defining an opening therethough, a surface defined on the body within the opening, a clamp movable in the opening and configured to selectively contact the surface, a separator blade movable within the opening, a rail, and a rail guide configured to slidably engage with the rod. The separator assembly is movable along the rail. Methods of moving the separator assembly are also disclosed.
