PURPOSE: To obtain a tubular material used in covering a container, a bottle, a can or a rod shaped article, by applying a solvent or a swelling agent to the adhesive layer formed to the whole or a part of at least the single surface of the bonding surfaces of the film in a tube and bonding the film before the solvent or the swelling agent is dried to form a tubular body.
CONSTITUTION: An an adhesive, any adhesives showing good adhesiveness to a polyester film can be used. For example, adhesives comprising a polyester copolymer, an acrylic copolymer, polyisocyanate (urethane), epoxy, synthetic rubber, cyanoacrylate, unsaturated polyester, polyvinyl alcohol or silicone capable of being adhered to the polyester film may be used but there is no limit. It order to prevent the heat-softening of a bonding part and the shift or release of the bonding part by the shrinking stress of a tube, it is recomended that a curing reactant is added to the adhesive.
