The CPU of this packaging device acquires parameters that can specify the amount of rotation for a film roller in the direction of unrolling a film. The CPU adheres a first section of the film to a pedestal (S17). The CPU conveys the pedestal from an upstream side to a downstream side with respect to an intersection position at which the conveyance pathway along which the conveyed pedestal passes intersects the movement pathway along which a guidance section can move (S25). The CPU moves the guidance section along the movement pathway when the upstream end of the pedestal has moved downstream of the intersection position (S29). The CPU conveys the pedestal to the upstream side after the guidance section has been moved. The CPU adheres a second section of the film to the pedestal when the upstream end of the pedestal has moved upstream of the intersection position. The CPU rotates the film roller in accordance with the parameters during at last a portion of the period before conveying the pedestal to the upstream side (S11).
