Abstract
A packaging machine with an atmosphere modifying station in which an atmosphere within a packaging to be produced can be modified by evacuating air and/or introducing a gas. The packaging machine has a pressure control device that may control an evacuation pressure and/or a gassing pressure. The pressure control device may comprise a first controllable 2/2-way valve and a second controllable 2/2-way valve, both which are configured to influence the evacuation pressure and/or the gassing pressure by setting a volume flow. The first and second 2/2-way valves are connected in parallel with one another and are controllable independently of one another. In one embodiment, the first and second 2/2-way valves are preferably electrically controllable. A method of modifying an atmosphere within a package using a packaging machine and pressure control device is also provided.
