せてから圧着する方法が提案されている。2. Description of the Related Art A conventional packaging material that uses a laminated material having a paperboard as a base material is formed into a final shape through a tubular body,
Laminates coated with polyolefin resin on both sides of paperboard have been widely used, but in this type of container, the polyolefin resin is thermally decomposed during molding and remains in the container, and there is no odor generated from the polyolefin resin itself. The contents to be packed and packed, for example, juice drinks, sake, mineral water, etc., and the polyolefin resin selectively adsorbs, absorbs or permeates aromatic components, volatile components, etc. of the contents, so that the contents are originally The taste, smell, flavor, and flavor that it should retain was impaired. Therefore, polyester resin, ethylene / vinyl alcohol copolymer, etc., which has less odor migration and is highly selective, non-adsorptive, non-absorptive and impermeable to aroma and volatile components, are used at least in the innermost layer of the container Liquid cartons have been developed. On the other hand, for contents that easily penetrate from the end surface of the laminated material such as alcohol solution, when performing blank tube sticking with envelope sticking, the outer surface of the blank end part that enters the inside of the container by envelope sticking Scraped to a specified width and thickness, folded outward so that the scraped part is half width, and heat-bonded the outer surface of the folded blank end and the inner surface of the other blank end with a specified width. A so-called skive hemming method is used to shield the end surface of the material. From the economical point of view, it is general that specifications such that the above polyester resin is used on at least the innermost surface and a polyolefin resin is used on the outermost surface are preferable. However, in this specification, the polyester resin surface on the inner surface of the laminated material is opposed to the strip-shaped "composite surface" composed of the polyolefin resin portion and the polyester resin portion which are adjacent to each other generated by the folding of the skive hemming method. It must be fully heat-bonded. Conventionally, there was no problem with thermal bonding between polyolefin resin parts, but polyester resin with a much higher melting point than such polyolefin resin, and thermal bonding between polyolefin resin and polyester resin at the same time were completely There are many difficult points to do, and various proposals have been made so far. In Japanese Unexamined Patent Publication No. 1-218823, a method of subjecting both surfaces facing each other to frame treatment, melting and then pressure bonding, and in Japanese Unexamined Patent Publication No. 1-241434, a polyolefin resin portion of the composite surface of a laminate having an aluminum layer is disclosed. And a method of subjecting the polyester resin surface facing it to a frame treatment, pressure-bonding and heat-sealing, and then high-frequency sealing the polyester resin portion of the composite surface and the polyester resin surface facing it, and Kaihei 5-2698
In Japanese Patent Laid-Open No. 93, the polyolefin-based resin portion of the composite surface and the polyester-based resin surface portion facing it are subjected to frame treatment to be melted, and then the polyester-based resin portion of the composite surface and the polyester-based resin surface facing it are melted. A method of melting with hot air and pressure bonding has been proposed.
Furthermore, Japanese Patent Application Laid-Open No. H5-254042 proposes a method in which only the polyolefin-based resin portion of the composite surface is pretreated by frame treatment, and then all the surfaces are melted by hot air and then pressure-bonded.

According to the method proposed in Japanese Patent No. 4042, a satisfactory initial adhesive strength can be obtained between the polyolefin-based resin portion of the composite surface and the polyester-based resin surface facing the composite resin surface, but cooling water is formed in the molded container. When water enters such as, and a lapse of a while, interfacial peeling occurs between the polyolefin-based resin and the polyester-based resin, foreign matter is apt to accumulate, causing mold and the like, and there is a problem that the appearance is deteriorated. The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a heat fusion method for obtaining a stable tube sticking portion in which the adhesiveness of the tube sticking portion does not change with time.
