Document Type and Number:
Japanese Patent JPS5249397
Kind Code:
B2
Abstract:
As a method of packing, an article to be packed is roughly packed by a packing film with thermal contractibility; a band or strip like film, which may be adherent to the packing film by heat fusion, is temporarily attached to the packing film around its outer surface; and the packing film is brought into close contact with the article to be packed by utilization of the thermal contractibility of the packing film. In this case, the softening and expansion of the packing film, immediately before the packing film starts its thermal contraction during a single heating process, causes the adhesion between the packing film and the band or strip like film.
