  • aluminum-vapor-deposited paper is generally used.
  • the aluminum-vapor-deposited paper has a paper layer and an aluminum film vapor-deposited on one surface of the paper layer.

  • the aroma-retaining capacity namely the capacity to retain the aroma of the smoking articles
  • the cigarette package further comprises a film enveloping the outer box, and the film includes a tear tape.

  • the above-described packaging for the smoking-article bundle has, however, a triple structure consisting of the aluminum-vapor-deposited paper, the outer box and the film, which is a factor causing an increase in the cost of the cigarette package.
  • the film is disposed of as nonburnable matter.
  • the existence of the film is a factor causing an increase of environmental burdens associated with disposal.

TABLE 2 Wrap- Wrapping Wrapping Wrapping ping paper C paper D paper E paper F Melting point ° C. 58.2 60.5 68.2 70.0 Concentration 2 2.1 6.0 13.2 (weight %) Application 6.4 6.2 6.4 6.5 quantity (g/m 2 ) Adhesive 20° C. 13.8 14.1 15.2 29.8 power at 30° C. 16.8 17.7 20.4 36.2 each 40° C. 18.5 21.4 22.2 44.9 measurement 50° C. 9.8 14.6 21.5 28.3 temperature 55° C. Unmeasurable 10.4 18.3 20.8 (mN/cm)
  • the moisture-proof layer 8 is formed from paraffin wax Q in the application quantity of 6 g/m 2 or more, and therefore has sufficient adhesive strength. Further, table 2 shows that when the concentration of isoparaffin in paraffin wax Q is 10 weight % or higher, the moisture-proof layer 8 has much increased adhesive strength.
  • FIG. 3 shows the relation between the paraffin wax Q application quantity and the peel strength of the first and second paper layers 4 , 6 when the pressure P applied to the laminated web LW is varied as a parameter.
  • FIG. 4 shows the relation between the paraffin wax Q application quantity and the peel strength of the first and second paper layers 4 , 6 when the temperature difference ⁇ (y) between the melting point of paraffin wax and the heating temperature for the laminated web LW is varied a parameter.
  • x in P(x) is a value in mPa
  • y in ⁇ T(y) is a value in ° C.
  • the peel strength increases.
  • the peel strength is, however, lower when the pressure P is 0.40 mPa than when the pressure P is 0.35 mPa.
  • the reason for this is thought to be that too high pressure P applied to the laminated web LW produces wrinkles in the first and second paper layers 4 , 6 , such wrinkles decreasing the peel strength.
  • FIGS. 5 and 6 show a cigarette package using the above-described embodiment of wrapping paper 2 .
  • the cigarette package comprises an outer box 44 , and the outer box 44 includes a box body 46 and a hinge lid 50 connected to the body box 46 with a separation line 48 between.
  • the hinge lid 30 can be rotated about a hinge 52 .
  • the outer box 44 is opened as shown in FIG. 6 .
  • the separation along the separation line 48 leaves break marks Z at the separation edge 46 a of the box body 46 as well as at the separation edge of the hinge lid 50 , that is, an opening-defining edge 50 a .
  • the outer box 44 is formed by folding a blank.
  • an inner pack 54 is contained with an inner frame 56 .
  • the inner pack 54 includes a cigarette bundle having 20 filter cigarettes FC and an inner wrapper 58 covering the cigarette bundle.
  • the inner wrapper 58 is made of the above-described wrapping paper.
  • the inner frame 56 has a U-shaped cross section, and partly covers the front surface and side surfaces of the inner pack 54 .
  • the hinge lid 50 when the hinge lid 50 is opened, the part of the inner frame 56 not covered by the box body 46 becomes exposed, where the edge of the inner frame 56 defines the opening of the box body 46 . Meanwhile, when the hinge lid 50 is closed, the hinge lid 50 covers the part of the inner frame 56 not covered by the box body 46 , where the opening-defining edge 50 a meets the separation edge 46 a of the box body 46 .
  • the inner frame 56 includes a front wall part 56 a not covered by the front wall of the box body 46 , and the front wall part 56 a has a U-shaped separation line 60 . Also the inner wrapper 58 of the inner pack 54 has a U-shape separation line 62 (see FIG. 9 ) corresponding to the separation line 60 .
  • the inner frame 56 and the inner wrapper 58 are separated along the separation lines 60 , 62 , respectively, so that a part of the inner frame 56 and a part of the inner wrapper 58 are separated off the other parts of the inner frame 56 and of the inner wrapper 58 , as separation pieces 64 , 66 , respectively.
  • a U-shaped aperture 68 is formed in the inner frame 56 , so that the cigarette bundle of the inner pack 54 becomes partly exposed, within the aperture 68 .
  • the separation pieces 64 , 66 which have been separated off the inner frame 56 and inner wrapper 58 are kept stuck to the inner surface of the hinge lid 50 .
  • the part of the inner frame 56 surrounded by the separation line 60 is bonded to the inner surface of the front wall of the hinge lid 50 by a glue applied region 70
  • the part of the inner wrapper 58 surrounded by the separation line 62 is bonded to the inner surface of the inner frame 56 by a glue applied region 72 .
  • the above-mentioned part of the inner wrapper 58 is bonded also to the ceiling surface of the hinge lid 50 with a glue applied region 74 .
  • the moisture-proof layer 8 present within the inner wrapper 58 satisfactorily protects the cigarette bundle, i.e., the individual cigarettes FC from moisture present outside the outer box 44 and satisfactorily prevents the aroma of the filter cigarettes FC from escaping to outside the outer box 44 , until the outer box 44 is opened.
  • the inner wrapper 58 stably maintains the quality of the cigarette bundle for a long period of time.
  • break marks Z are left at the separation edge 46 a of the box body 46 and the opening-defining edge 50 a of the hinge lid 50 .
  • the production of the break marks Z is useful to prevent tampering with the cigarette bundle.
  • the cigarette package only requires the outer box 44 that covers the inner pack 56 , not requires a film that covers the outer box 44 . Accordingly, not only excess packaging of the cigarette bundle can be avoided, but also the need to dispose of the film is obviated.
  • the cigarette package according to the present invention contributes much to a decrease of environmental burdens.
  • the moisture-proof layer 8 of the inner wrapper 58 does not come into direct contact with the filter cigarettes FC, and in addition, the moisture-proof layer 8 is odorless. Thus, the moisture-proof layer 8 does not have an adverse effect on the aroma of the filter cigarettes FC.
  • first and second paper layers 4 , 6 of the inner wrapper 58 are made of glassine paper.
  • the static and kinetic friction coefficients for the first and second paper layers 4 , 6 are smaller, as compared with a paper layer made of aluminum-vapor-deposited paper generally used as the inner wrapper, and a paper layer made of waxed paper used as wrapping paper for a carton.
  • the glassine paper is very thin, the resilience of the inner wrapper 58 resisting folding is small although the inner wrapper 58 has the above-described triple-layer structure. Accordingly, the inner wrapper 58 can be easily folded around the cigarette bundle, and after folding, the inner wrapper 58 does not unfold back. Thus, the inner wrapper 58 can be stably folded around the cigarette bundle, and therefore, the wrapping paper 2 is particularly suitable for the inner wrapper of the inner pack 56 .
  • first and second paper layers 4 , 6 of the inner wrapper 58 are both translucent, but exceptionally, they are allowed to be not translucent. However, if one of the first and second paper layers 4 , 6 is translucent, one surface of the translucent paper layer can be used as a printing surface to print desired character information, designs, etc., on.
  • the surface of the second paper layer 6 in contact with the moisture-proof layer 8 can be used as a printing surface.
  • information, etc. can be printed on the printing surface, in desired positions such as on the front face and side faces of the inner pack 56 , as indicated by hatching in FIG. 9 .
  • a printing unit 76 can be disposed on the second feed path 32 for the second paper web W 2 , as shown in FIG. 2 .
  • information, etc. may be printed on the second paper web W 2 in advance.
  • the wrapping paper according to the present invention is suited not only for the inner wrapper 58 of the inner pack 56 but also for wrapping various articles that dislike moisture.
