         6 . A packaging machine which unrolls a lower material web from a supply roll and transports the lower material web intermittently or continuously along the packaging machine and which is being loaded with a material to be packaged, wherein, for completion of a packaging, an upper material web is subsequently sealed to the lower material web in a sealing station, wherein a punch is provided which severs the lower material web along at least one partial area of a contour of the packaging to be produced, wherein the punch is provided in a forming tool. 
     
     
         7 . The packaging machine according to  claim 6 , wherein the punch has a knife and a counter knife. 
     
     
         8 . The packaging machine according to  claim 6 , wherein a knife of the punch is provided on a lower tool of the forming tool, and a counter knife is provided on an upper tool of the forming tool, or vice versa. 
     
     
         9 . The packaging machine according to  claim 8 , wherein the forming tool has a clamping plane in which the forming tool rests against the lower material web and the knife protrudes from the clamping plane. 
     
     
         10 . The packaging machine according to  claim 8 , wherein the counter knife and/or the knife is/are elastically and/or longitudinally displaceably mounted on the forming tool. 
     
     
         11 . The packaging machine according to  claim 10 , wherein a degree of elasticity and/or longitudinal displacement of the mounting of the counter knife and/or the knife is variable. 
     
     
         12 . The packaging machine according to  claim 7 . wherein the knife is provided to be stationary. 
     
     
         13 . The packaging machine according to  claim 7 . wherein the knife and/or the counter knife is provided to be adjustable.
