A platen machine for filling and sealing packages is provided having an upper platen and a lower platen journalled and independently moveable on a common alignment shaft to provide a close tolerance sealing mechanism with an independently operated heat seal element. The novel platen machine relocates clamping forces from the support frame to the alignment shaft so that the common alignment shafts bears the clamping forces and the carrier merely relies upon the frame to support the weight of the machine and not clamping forces. The upper platen moves toward the lower platen and the lower platen moves toward the upper platen to clamp a package between the two platens before an independently operated heat seal element is activated to advance to the clamped package and provide a heating and sealing cycle independent of the clamping cycle. Optional filling, gassing and evacuation can be provided during the clamping of the package without involving the separate heating and sealing operation.
