The present invention provides a wrapping device for welding a stretch film to a tray, and particularly a wrapping device that can provide a good appearance after the wrapping, and can suppress disadvantages in a transporting operation. A wrapping device 1 covers a top opening of a tray T with a stretch film Fm, welds the stretch film to the tray T, and thermally cuts it. The wrapping device 1 includes a stretch mechanism 9, a control portion and a film winding portion 53. The stretch mechanism 9 stretches the stretch film Fm. The control portion controls the stretch mechanism 9 to stretch the stretch film Fm at least before welding the stretch film Fm to the tray T. The film winding portion 53 winds up the stretch film Fm after the thermal cutting.
