Abstract
A packaging machine and method for producing a packaging with a packaging machine, in which a lower material web is unrolled from a supply roll and transported along the packaging machine and at the same time a material to be packaged is placed on the lower material web and, to complete the packaging, an upper film is sealed to the lower material web in a sealing station, the packaging is cut from the upper and lower material webs, the cutting of the lower material web takes place partially upstream and partially downstream of the sealing station and/or partially upstream and partially in the sealing station.

A method for producing a packaging with a packaging machine, the method comprising:
- unrolling a lower material web from a supply roll;
- transporting the lower material web along a transport direction of the packaging machine;
- forming a packaging trough into the lower material web with a forming tool in a forming station to include a base and a horizontal flame that extends horizontally from the base;
- placing a material to be packaged in the packeting trough;
- sealing an upper film to the horizontal flame of the packaging trough in a sealing station;
- wherein before and/or during the forming step in which the packaging trough is formed in the lower material web, the method comprises completely severing one or more sections of the lower material web resulting in one or more corner areas of the horizontal flame being completely several from the horizontal flange.
A method for producing a packaging with a packaging machine, in which a lower material web is unrolled from a supply roll and transported along the packaging machine the method comprises forming a packaging trough in the lower material web with a forming tool, placing a material to be packaged in the packaging trough, and sealing an upper film to the lower material web in a sealing station to complete the packaging, wherein the packaging trough comprises a flange to which the upper film is sealed in the sealing station, wherein the flange comprises a corner area where a section of the lower material web is completely cut from the flange before and/or during the forming of the packaging trough resulting in the flange having a straight edge in the corner area remaining where the section of the lower material web was completely cut, and wherein the method comprises forming one or more opening aids on the flange of the packing trough to facilitate releasing the upper film from the packaging trough, wherein the one or more opening aids comprise a depression formed in a top surface of the flange that is a low spot relative to a remainder of the top surface of the flange.
