A packaging machine is described. A plurality of working stations is arranged between the input side and output side of the machine. A conveyor moves packages carrying a product along a path from the input side to the output side through the working stations. A device feeds a cover film onto the packages. The cover film has two layers bonded together with a limited bonding strength. A first layer has a portion protruding beyond said second layer. Another device separates the first layer from the second layer in a defined region extending across the cover film transversely to the conveyor path. The separator seals the defined region of the cover film and supplies a pressurized fluid to said defined region. The defined region includes at least part of the protruding portion of the first layer. A method of using the packaging machine to package product also is described along with the package that is made.
