摘要：As a method of packing, an article to be packed is roughly packed by a packingfilm with thermal contractibility; a band or strip like film, which may be adherent to thepacking film by heat fusion, is temporarily attached to the packing film around its outersurface; and the packing film is brought into close contact with the article to be packedby utilization of the thermal contractibility of the packing film. In this case, the softeningand expansion of the packing film, immediately before the packing film starts its thermalcontraction during a single heating process, causes the adhesion between the packingfilm and the band or strip like film.
