The invention relates to a method for producing a packaging bag from a flexible film material () comprising the following steps: feeding of the flexible film material (); adding an additional material () to the flexible film material () and producing at least one stiffened partial region () from the additional material (), wherein the additional material () is hardened and forms the stiffened partial region (). The invention further relates to a device for producing a packaging bag, comprising: a film feeding device () for feeding flexible film material () and an additional material adding device () for adding an additional material (). The invention further relates to a packaging bag () comprising: a first transverse seal seam (), a second transverse seal seam (), a flexible partial region () and at least one stiffened partial region (), wherein the flexible partial region () is produced from the film material () and the stiffened partial region () is produced from an additional material () which was added and hardened to stiffen the packaging bag.

Method and device for producing a packaging bag from flexible film material and stiffened partial region and packaging bag

An apparatus for producing packages having a heating device for heating a bottom sheeting strip, a forming device, a filling device, a sealing device for sealing on a top strip, and a cutting device for separating the packages. For forming downward-drawn rims on the packages that make them easy to drink from, additional recesses are embodied in the forming device, and the bottom sheeting strip is pressed by means of protrusions into recesses disposed on the upper part of the forming device. The cutting device also has a stamping knife, which cuts the package out of the foil composite in the region of the downward-drawn rim.

Apparatus for producing packages

A method of producing overpressure valves for packaging containers supplied in a roll, transported in this form to a packaging machine, separated at the machine and attached to packaging containers by means of an adhesive coated surface. For this purpose the overpressure valves have a layer of emulsion bonding on their underside. To prevent individual layers of the roll from sticking together, the overpressure valves have an adhesive-repelling layer on their top side. The overpressure valves are connected to one another in one piece and in a row, and are separated consecutively in a packaging machine.

Method of producing overpressure valve for packaging containers

Overpressure valves for packaging containers are supplied in a roll, transported in this form to a packaging machine, separated here and attached to packaging containers by means of an adhesive coated surface. For this purpose the overpressure valves have a layer of emulsion bonding on their underside. To prevent individual layers of the roll from sticking together, the overpressure valves have an adhesive-repelling layer on their top side. The overpressure valves are connected to one another in one piece and in a row, and are separated consecutively in a packaging machine.

Overpressure valve for packaging containers

A bag evacuating and closing apparatus having two opposing jaws which face ends that move toward one another. The jaws encompass a top closure of a bag package to be sealed. The jaws have hollow spaces open toward one another which are surrounded by frames with sealing jaws disposed in the hollow spaces; the hollow spaces form a chamber that receives the top closure of the bag package. A sealing rib protrudes from one face end of the two frames and is interrupted in a middle region of the frame part at which the closure fold protrudes between the jaws. In this region, suction openings are disposed in the frame parts of both jaws; these suction openings pull two walls of the top closure tightly against the frame parts. After the top closure of the bag package has been tightly encompassed, air is extracted from the bag package by a vacuum, and subsequently, the top closure of the package is tightly sealed by the sealing jaws which form a sealing seam to close the upper end of the bag.

Apparatus for evacuating and closing bag package

An improved opener for a packaging container arranged to form an opening in one wall to remove the contents includes a tear-open portion surrounded by a weakening line and a pull tab connected to the tear-open portion. To enable use of the pull tab as a reclosure element, it has a stopper-like lower extension which has a complemental outline to that of the tear-open portion and on which a shear edge is disposed. The pull tab is firmly connected to the tear-open portion with a narrow strip of a fusing glue.
