Description

[Detailed explanation of the idea]

The present invention relates to a cigarette packaging material, and more particularly to an inner wrapping material for a cigarette package that is cheaper than conventional products and has excellent moisture resistance. Conventional inner packaging materials for cigarette packaging include polymerized or bonded aluminum foil and paper, as well as colored and embossed materials used in Japan.For some products from other countries, Recently, paper on which a metal film is vacuum-deposited (hereinafter referred to as vapor-deposited paper), or vapor-deposited paper with a stamp on it have been used. Among these inner packaging materials, aluminum ingots and aluminum foil have become expensive due to the rise in energy costs in recent years, and there is a strong demand for inexpensive substitutes for laminating materials of aluminum foil and paper.
This economical requirement can be solved by using the above-mentioned metallized paper, but it can be avoided that metallized paper is inferior to the laminated material of aluminum foil and paper in terms of metal selectivity, smoothness, and beauty. If these points are to be improved, it is important to first eliminate the unevenness on the surface of the base paper used. Therefore, in order to eliminate unevenness on the surface of the base paper, it is necessary to apply paint as a filler to a predetermined thickness on the surface of the base paper that will be vapor-deposited. It is necessary to select and thicken the coating film of the above sealing paint. Furthermore, since the moisture content of the paper has a significant effect on the finish of the product, it is essential to strictly control the moisture content of the base paper. This will ultimately result in higher costs. On the other hand, in order to eliminate such problems, it is possible to vacuum-deposit metal on one side of a synthetic resin film and adhere paper material to the metal-deposited surface.
When such a material is used as a cigarette packaging material, a major problem arises in that the synthetic resin film prevents the package from breaking when it is opened, making it difficult to open. The present invention was created after careful consideration and recognition of the economical issues with the above-mentioned aluminum foil and paper bonding material, as well as the quality issues with metallized paper.
To provide an inner packaging material for a cigarette package that is inexpensive, has excellent moisture resistance, can be easily torn when opened, and is beautiful and has a rich luster. To explain the embodiment of the present invention with reference to the drawings, A
is the inner wrapping material of the cigarette package, which is formed into a rectangular shape as shown in FIG. A base material 3 having a vapor-deposited layer 2 is obtained by vapor-depositing aluminum, and a paper material 5 is polymerized and bonded to the base material 3 via an adhesive 4. As the synthetic resin film 1 described above, polypropylene film, polyester film, etc. are suitable, and sufficient moisture resistance can be obtained with a film thickness of about 12μ in the case of polypropylene and about 6μ in the case of polyester. . However, when the synthetic resin film 1 is used, there is a problem with the ease of opening the cigarette when taking it out from the tobacco package, but this problem can be solved by using a uniaxially stretched film 1, with the stretching direction being the longitudinal direction of the cigarette. In order to make it easy to tear the film in the longitudinal direction as well as to tear it in the transverse direction, as shown in FIGS. A shallow cutting line 6 is provided on the surface. Further, it is preferable that the paper material 5 described above is polymerized and adhered to the aluminum vapor deposited layer 2 side, so that a water-soluble vinyl acetate emulsion can be used as an adhesive as in the past, and the selectivity of the paper material 5 is not required. It's convenient. As described above, the inner wrapping material of the cigarette package of the present invention is made by vapor-depositing aluminum on one side of a transparent or translucent uniaxially stretched synthetic resin film 1 to form a vapor-deposited layer 2.
A paper material 5 is polymerized and bonded to the side via a water-soluble vinyl acetate adhesive 4, and a cutting line 6 perpendicular to the stretching direction is cut at a portion of the synthetic resin film 1 corresponding to the upper position in the cigarette packaging form. The uniaxially stretched synthetic resin film 1 makes it easy to tear the inner packaging when opening the package.

[Table] As mentioned above, the cigarette inner packaging material A of the present invention is far superior to conventional products not only in economical efficiency but also in moisture resistance, and can be colored and embossed in the same way as before, making it suitable for use with paper. Because of this, it is strong, and in addition, the uniaxially stretched synthetic resin film 1 and the cutting lines 6 perpendicular to the stretching direction provided at predetermined locations on the film 1 enable smooth and reliable opening. It has great practical effects as an inner packaging material for cigarette packages such as cigarettes, etc.
