Abstract: A packaging kit is composed of a sheet member. A target object to be packaged is to be placed on the sheet member. The sheet member includes a placement surface, a standing side, and a tongue piece. The placement surface allows the target object to be placed thereon. The standing side is elongated from the placement surface. The standing side is raised relative to the placement surface. The tongue piece includes a protrusion edge. The placement surface and the standing side are provided with the tongue piece. The tongue piece is located on a side of at least one side edge of the standing side.

Abstract: A packaging kit manufacturing apparatus (600) manufactures a packaging kit (501). The packaging kit manufacturing apparatus (600) includes: a film feeding section (610) that feeds a film (31, 32); a conveyance section (620) that conveys a plate-shaped member (510) such that a leading end of the plate-shaped member (510) pushes the film (31, 32); a welding section (640) that welds the film (31, 32) to form a tubular film (530); a retracting section (650) that retracts the film (32) to fold the plate-shaped member (510) along a fold line (21) before the welding section (640) welds the film (31, 32); and a lift restricting section (660) that restricts lift of the leading end of the plate-shaped member (510) when the film (32) is retracted by the retracting section (650).
