The method of the outer wall surface and the like. In the third example, in the first and second examples, the end portion of the outer paper-like tubular body is cut into a straight line, and a step portion formed to protrude in a stepped shape or a step portion protruding outward is provided on the outer wall surface. At least one auxiliary aileron is adhered. In order to form a stepped portion that protrudes outward from the end, at least one auxiliary aileron is adhered to the outer wall surface, and the sealing can be performed in the same manner as in the first and second examples. In the fourth example, the end portion of the outer layer of the paper-like tubular body is cut into a straight line, and the tubular body made of the inner polyethylene resin is sealed by heat sealing. The ends of the inner and outer cylindrical bodies are combined into a line and then combined, and the surface is wrapped like a wrapper. The adhesive can be adhered to the seal. Further, the unsealing tape is first set to the lateral direction on the surface paper, and when the paper bag is opened, the opening tape is opened to tear the surface of the paper to the lateral direction, and can also be used as a structure which can be easily opened by unsealing the end of the stepped end. In the method of the fifth example, the end portion of the outer paper-made cylindrical body is cut into a straight line, and the ends of the cylindrical body are spliced into a line and then combined, and the bent end portion is like a bent portion. Put on the paper and use an adhesive to stick the seal. When this is -13- (10) 1294395, the strength is maintained because of the bend of the 2 bends. At this time, the unsealing tape can be set to the lateral direction on the surface paper in the same manner as in the fourth example. In the method of the sixth example, 'the stepped portion of the paper-like cylindrical body on the outer layer is formed as a stepped portion by a stepped surface, or is formed as an auxiliary aileron on a straight end portion, on the surface thereof. The adhesive layer covered with the release paper is provided, and the folding paper step portion or the auxiliary aileron can be peeled off and attached to the outer wall surface of the kraft paper for sealing when sealing (refer to Japanese Patent Laid-Open No. 2000- 1 90989). In a method, a stepped portion is formed by a stepped surface at an end portion of the outer layer of the paper cylindrical body, or is formed as an auxiliary aileron attached to the straight end portion, at the step of bending or auxiliary auxiliary In the case of the wing, an adhesive layer covered with a release paper is disposed on the outer wall surface of the laminated paper cylinder, and the release paper folding step portion or the auxiliary aileron can be peeled off and attached to the outer wall surface of the kraft paper during sealing. Sealed (refer to Special Opening 200 1 -27 829 0). The adhesive to be used is not particularly limited, and a conventional adhesive can be suitably used, but the portion where the mouth end of the bag having the pleats must adhere in a short time, the use of the hot-melt adhesive More satisfactory. When the contents are packed in the wrinkled bag of the present invention and then sealed, the bottom of the bag can be sealed by the above-described methods to provide a bag as a contents for mounting. As a method of sealing the bottom, the method of the third example described above is optimal. When the bag having the pleats provided by the above-described method is used, the heat-fusible adhesive which is previously applied to the end of the mouth is re-activated by a heat source such as hot air, and then sealed. The job is a very good form. -14- (11) 1294395 The contents of the bag at the bottom end of the closure are mounted. The above methods can be used as a suitable method in order to seal the mouth end. Among them, as a suitable method, the methods of the first to third examples can be cited. In particular, the method of sealing the bottom end portion by the above-described fifth method is the most suitable method for sealing the end portion of the mouth portion after the contents have been sealed by the second or third method. When the bottom end is sealed, the unsealing tape is first set to the lateral direction on the surface paper, and when the paper bag is opened, it is satisfactory to increase the unsealing tape to tear the surface paper laterally as a structure that is easily opened. In the tubular body having the composite pleats of the present invention, a heat-sealing layer can be used from the upper side of the outer layer cylindrical body to heat-seal the tubular body having the pleats made of a polyethylene resin. The heat sealing condition at this time is preferably a slight low pressure and a high temperature, and the temperature at about 290 °C is most recommended. Under such conditions, when the wrinkled cylindrical body of the present invention is heat-sealed, it is sometimes considered that the portion adjacent to the heat-sealed position is adhered, but the adhesive which is considered to be the immediate portion is ideal. form. A preferred example of the tubular body having the composite pleats of the present invention will be described with reference to Fig. 2 . The tubular body 18 having the composite pleats in Fig. 2 is a pleated cylindrical body composed of an outer layer of kraft paper, and a wrinkled cylindrical body composed of an inner layer of a polyethylene resin, in order to create The step portion is provided with auxiliary ailerons at the upper end of the kraft paper of the outer layer, and the lower end portion is cut into a straight line. In order to better understand the structure of the tubular body having the composite pleats of Fig. 2, a cross-sectional side view thereof is shown in Fig. 3. As shown in FIG. 3, the one-side outer wall surface 8a corresponding to the end portion of the tubular body portion having the composite pleat- 15-(12) 1294395 pleat is adhered to the same width as the outer wall surface with the adhesive 17 One end portion 9a, 1 Oa of the two auxiliary ailerons 9, 10. The auxiliary aileron 9 has a length in which the other end portion 9b protrudes outward from the mouth end portion of the corrugated cylindrical body 8, and the auxiliary aileron 1' is disposed to overlap the outer side of the auxiliary aileron 9 The other end portion 1 Ob is a length that protrudes outward by the end portion 9b of the inner auxiliary aileron 9. The hot-melt adhesive 11 is applied only to the step portions of the other end portions 9b and 1 Ob of the auxiliary ailerons 9, 10. An example of sealing the end portion of the tubular body having the composite pleats of the present invention will be described with reference to Fig. 4 . Fig. 4 is a cross-sectional view showing the end portion of the lower end portion of the tubular body having the composite pleats of Fig. 2, which is heat-sealed at a position of 15 and bent twice at a broken line 16 to seal the end portion.

Since the wrinkled cylindrical body composed of the polyethylene-based resin of the present invention has a high heat-sealing strength, the heat-sealing position can be arbitrarily selected, and the sealing method can be freely selected. For example, the lower end portion of the tubular body having the composite pleats of Fig. 2 may be sealed in the form of Figs. 5 to 7 . On Figure 5, the bend of Figure 4 is only once. In Fig. 6, the heat-sealed position of the tubular body having the pleats formed of the inner polyethylene resin is also changed. Further, in Fig. 7, the inner layer and the outer layer were not bent and sealed. Fig. 8 is a cross-sectional view showing the state in which the end portion is sealed at the upper end portion of the tubular body having the composite pleats of Fig. 2; As shown in Fig. 5, the end portion of the inner cylindrical body 7 is heat-sealed at a portion between the two broken lines of -16-(13) 1294395 of 1 2, and the broken line 16 bends the mouth of the bag to After the heat is reactivated, the other end portions 9b and the steps of the auxiliary ailerons 9, 10 are completely adhered to the outer wall surface 8b of the wrinkled bag, and the outer surface 8b is sealed. In this way, the wrinkle bag which seals the mouth and the bottom is excellent in strength, can maintain the crack in the conveyance, and the good shape of the goods does not collapse, and also has no inner layer when opening. The resin bag is easy to remove. After removing the inner layer bag, the dust is removed and, if necessary, disinfected, and the environment where the environmental standard is tight, such as bringing it into a clean space, exhibits excellent properties of the polyethylene resin bag of the present invention.
