A packaging machine comprises a base frame having an input side and an output side as well as a transport path from the input side to the output side. A plurality of tray carriers for holding trays are arranged in succession from the input side to the output side along the transport path. A drive means advances the tray carriers in an advancement plane. Further, feed means are provided for feeding a cover film for covering the filled trays. Successive tray carriers are pivo- tally interconnected by means of pivoting coupling links. Each tray carrier has engagement elements provided at its forward and rearward side. The drive means is formed as a drive chain with a chain strand trained over chain wheels and the engagement elements engage the chain strand when in a po- sition adjacent thereto. The feed means for the cover film likewise includes laterally guided chain strands which are guided in a plane parallel to the first chain strand along a predetermined length parallel to the first chain strand and at a predetermined distance therefrom. The engagement ele- ments engage the first chain strand along a predetermined length and also the second chain strand along a predetermined length whereby both drive chains are driven by the same drive means.
