A heating-nozzle arrangement for heating a partly formed packaging container, comprises one or more nozzle assemblies, arranged to direct a heated air flow to portions of a packaging container to be sealed; a gas-supply portion, arranged to supply a mass flow of heated gas to the nozzle assembly, further the nozzle assembly comprises at least a first and a second hole pattern and that the heating-nozzle arrangement further comprises a selector for directing the mass flow of heated air towards the first hole pattern or the second hole pattern respectively.

The invention is directed to a system and method for hermetically sealing a closure to a container comprising a die assembly and a mandrel assembly. The mandrel assembly comprises an outer mandrel, an inner mandrel, and an ejector disposed within an inner circumference of the inner mandrel. At least the outer mandrel is configured to translate a first distance in a first time period, the inner mandrel and the ejector are configured to translate a second distance in a second time period, the inner mandrel is configured to retract a third distance in a third time period, and the ejector is configured to retract the third distance in a fourth time period.

A method for producing packages is presented. The method comprises providing a web of packaging material comprising at least an outer protective layer, a cellulose-based mid-layer and an inner protective layer, providing a protective strip, heating a first longitudinal edge section of an inside surface of the web by applying a first flow of heated air via a first nozzle, heating a first longitudinal edge section of an inside surface of the protective strip by applying a second flow of heated air via a second nozzle, attaching the outside surface of the first longitudinal edge section of the protective strip onto the inside surface of the first longitudinal edge section of the web, forming a tube of the web of packaging material, attaching an outside surface of the first longitudinal edge section onto an inside surface of the second longitudinal edge section, attaching an inside surface of a second longitudinal section of the protective strip onto an outside surface of a mid-section of the web, filling the food product into the tube, sealing the tube transversally in transversal sealing sections in a lower end of the tube, and cutting the tube in the transversal sealing sections such that the packages are formed.
