PURPOSE:To obtain a very beautiful and simple package by cutting off a tray packed with goods conveyed at a fixed interval after folding down and sticking them in U-shape along the conveyer line, and finally, making film shrunk with heat. CONSTITUTION:A uncompleted tray 1 made of thick paper such as corrugated fibreboard is carried by a conveyor being packed with goods 2. Required quantity of thermoshrinking film 3 is evenly drawn out over the goods 2 through tension rollers 5 during the conveyance. The film is folded down in U-shape along the conveyor line with a guide 6, and lower end 8 of the folded down film 3 is stuck on the tray 1 by heating with sticking rollers 7 provided, with regard to the conveying direction, in both left and right sides of the tray 1. The stuck film 1 is cut off with cutters 12 while being carried and drawn, then the film shrinks with heat while passing through a heat tunnel, and completes a beautiful package by closely adhering to the goods 2 and the tray 1.
