A packaging device includes a conveyance mechanism, a first guide portion, and a processor. The conveyance mechanism is configured to convey, along a conveyance path, a base on which an object is placed. The first guide portion is configured to guide a film and to move along a movement path. The processor is configured to cause the conveyance mechanism to convey the base toward a downstream side in a conveyance direction. The processor is further configured to cause the first guide portion to move along the movement path from above to below the conveyance path after the base is conveyed toward the downstream side to a first position. The processor is further configured to cause the conveyance mechanism to convey the base toward the upstream side to a second position after the first guide portion is moved to below the conveyance path.
