　しかし、特許文献１の技術では、ポケットティシューの長手方向の両側面の剛性が小さいために、複数のフィルム包装ティシュー集合包装体を段積みした場合には、最下段に位置するフィルム包装ティシュー集合包装体が圧縮によって潰れるという問題があった。 However, in the technique of Patent Document 1, since the rigidity of both side surfaces in the longitudinal direction of the pocket tissue is small, when a plurality of film packaging tissue assembly packages are stacked, the film packaging tissue assembly package located at the bottom is located at the bottom. There was a problem that the body was crushed by compression.
　そこで、本発明の課題は、圧縮荷重に対して耐力が大きいフィルム包装ティシュー集合包装体を提供することにある。 Therefore, an object of the present invention is to provide a film packaging tissue package package having a large yield strength against a compressive load.

The first means is in a film packaging tissue assembly package in which a plurality of film packaging tissue is stored in a gusset packaging bag.
The film packaging tissue is formed by covering a bundle of tissue paper obtained by folding a plurality of tissue papers in a pop-up manner with a packaging film, and the longitudinal direction of the film packaging tissue is arranged along the vertical direction of the gusset packaging bag. , The first surface of the film packaging tissue and the second surface of the film packaging tissue adjacent to the film packaging tissue are opposed to each other and arranged in the left-right direction of the gusset packaging bag, and one in the longitudinal direction of the film packaging tissue. The side side surface is opposed to the top surface of the gusset packaging bag, the other side surface in the longitudinal direction of the film packaging tissue is arranged to face the bottom surface of the gusset packaging bag, and the one side surface and the other side surface are arranged. , The wrapping film is formed by folding it into a caramel wrapping.
　第２手段は、第１手段の構成において、前記ティシュペーパー束の折返し縁を、フィルム包装ティシューの長手方向に沿って延在させたことを特徴とする。 The second means is characterized in that, in the configuration of the first means, the folded edge of the tissue paper bundle is extended along the longitudinal direction of the film packaging tissue.
　第３手段は、第１又は２手段の構成において、前記フィルム包装ティシューの圧縮率を８０～１００％に形成したことを特徴とする。 The third means is characterized in that, in the configuration of the first or second means, the compressibility of the film packaging tissue is formed to 80 to 100%.
　第４手段は、第１～３のいずれか１項の手段の構成において、前記フィルム包装ティシューの充填率を９５～１０５％に形成したことを特徴とする。 The fourth means is characterized in that, in the configuration of the means according to any one of the first to third items, the filling rate of the film packaging tissue is formed to 95 to 105%.
　第５手段は、第１～４のいずれか１項の手段の構成において、前記フィルム包装ティシュー集合包装体の圧縮率を８５～１２５％に形成したことを特徴とする。 The fifth means is characterized in that, in the configuration of the means according to any one of the first to the fourth, the compressibility of the film packaging tissue assembly package is formed to 85 to 125%.
　第１手段によれば、フィルム包装ティシューを、複数のティシュペーパーをポップアップ式に折畳んだティシュペーパー束を包装フィルムで覆って形成し、フィルム包装ティシューの長手方向を、ガセット包装袋の上下方向に沿って配置し、フィルム包装ティシューの第１面と、フィルム包装ティシューに隣接するフィルム包装ティシューの第２面を対向させて、ガセット包装袋の左右方向に配置し、フィルム包装ティシューの長手方向の一側側面を、ガセット包装袋の天面に対向させ、フィルム包装ティシューの長手方向の他側側面を、ガセット包装袋の底面に対向させて配置し、一側側面と他側側面を、包装フィルムをキャラメル包装に折畳んで形成したので、フィルム包装ティシューの一側側面と他側側面の剛性が高まり、一側側面と他側側面に加わる圧縮荷重に対する変位量を抑制することができる。これにより、店頭で複数のフィルム包装ティシュー集合包装体を４段積みして展示することができる。 According to the first means, the film packaging tissue is formed by covering a bundle of tissue paper obtained by folding a plurality of tissue papers in a pop-up manner with a packaging film, and the longitudinal direction of the film packaging tissue is set in the vertical direction of the gusset packaging bag. Arranged along the gusset packaging bag, the first surface of the film packaging tissue and the second surface of the film packaging tissue adjacent to the film packaging tissue face each other, and are arranged in the left-right direction of the gusset packaging bag. The side side surface is arranged so as to face the top surface of the gusset packaging bag, the other side surface in the longitudinal direction of the film packaging tissue is arranged so as to face the bottom surface of the gusset packaging bag, and one side surface and the other side surface are arranged with the packaging film. Since it is formed by folding it into a caramel package, the rigidity of one side surface and the other side surface of the film packaging tissue is increased, and the amount of displacement with respect to the compressive load applied to the one side surface and the other side surface can be suppressed. As a result, a plurality of film packaging tissue assembly packages can be stacked and displayed in four stages at the store.
　第２手段によれば、第１手段による効果に加えて、ティシュペーパー束の折返し縁を、フィルム包装ティシューの長手方向に沿って延在させたので、フィルム包装ティシューの一側側面と他側側面に加わる圧縮荷重に対してティシュペーパー束の耐力を高めることができる。 According to the second means, in addition to the effect of the first means, the folded edge of the tissue paper bundle is extended along the longitudinal direction of the film packaging tissue, so that one side surface and the other side surface of the film packaging tissue are extended. It is possible to increase the yield strength of the tissue paper bundle against the compressive load applied to the tissue paper bundle.
　第３手段によれば、第１又は２手段による効果に加えて、フィルム包装ティシューの圧縮率を８０～１００％に形成したので、ティシュペーパー束の空隙を低減して、ティシュペーパー束の剛性を高め、ティシュペーパー束の変位量をより抑制することができる。 According to the third means, in addition to the effect of the first or second means, the compressibility of the film packaging tissue was formed to 80 to 100%, so that the voids in the tissue paper bundle were reduced and the rigidity of the tissue paper bundle was increased. It can be increased and the displacement amount of the tissue paper bundle can be further suppressed.
　第４手段によれば、第１～３のいずれか１項の手段による効果に加えて、フィルム包装ティシューの充填率を９５～１０５％に形成したので、フィルム包装ティシューの一側側面と他側側面に加わる圧縮荷重を、一側側面と他側側面に対向するティシュペーパー束の両側面の全面に均等に分布させることができ、フィルム包装ティシューの変位量をさらに抑制することができる。 According to the fourth means, in addition to the effect of any one of the first to third means, the filling rate of the film packaging tissue was formed to 95 to 105%, so that one side surface and the other side of the film packaging tissue were formed. The compressive load applied to the side surface can be evenly distributed over the entire surfaces of both side surfaces of the tissue paper bundle facing the one side surface and the other side surface, and the displacement amount of the film packaging tissue can be further suppressed.
　第５手段によれば、第１～４のいずれか１項の手段による効果に加えて、フィルム包装ティシュー集合包装体の圧縮率を８５～１２５％に形成したので、フィルム包装ティシューと隣接するフィルム包装ティシューの間隔を維持して、フィルム包装ティシューの傾きを防止することができる。 According to the fifth means, in addition to the effect of any one of the first to fourth means, the compressibility of the film packaging tissue assembly package was formed to 85 to 125%, so that the film adjacent to the film packaging tissue was formed. The spacing between the packaging teaches can be maintained to prevent the film packaging tips from tilting.

　図３に示すように、フィルム包装ティシュー１０は、複数のティシュペーパー２１をポップアップ式に折り畳んで積層した形成されたティシュペーパー束２０と、ティシュペーパー束２０を収納する包装フィルム３０から形成されている。なお、本実施形態のティシュペーパー２１は、前後方向の長さが１９７ｍｍで、左右方向の長さが１７８ｍｍで、ティシュペーパー束２０は、２プライに形成されたティシュペーパー２１が１５０組積層されて形成されている。 As shown in FIG. 3, the film packaging tissue 10 is formed of a tissue paper bundle 20 formed by folding and stacking a plurality of tissue papers 21 in a pop-up manner, and a packaging film 30 for storing the tissue paper bundle 20. .. The tissue paper 21 of the present embodiment has a length of 197 mm in the front-rear direction and a length of 178 mm in the left-right direction. It is formed.
　＜ティシュペーパー束＞
　ティシュペーパー束２０に積層された二つ折りにされたティシュペーパー２２の折返し縁２２Ａは左側に位置し、二つ折りにされた上側部２２Ｂは折返し縁２２Ａから右上方に延在し、下側部２２Ｃは折返し縁２１Ａから右下方に延在して形成される。 <Tish paper bundle>
The folded edge 22A of the folded tissue paper 22 laminated on the tissue paper bundle 20 is located on the left side, and the folded upper portion 22B extends upward to the right from the folded edge 22A, and the lower portion 22C. Is formed extending downward to the right from the folded edge 21A.
　ティシュペーパー２２の上側に隣接して積層されたティシュペーパー２３の折返し縁２３Ａは右側に位置し、上側部２３Ｂは折返し縁２３Ａから左上方に延在し、下側部２３Ｃは折返し縁２３Ａから左下方に延在して形成され、ティシュペーパー２２の下側に隣接して積層されたティシュペーパー２４の折返し縁２４Ａは右側に位置し、上側部２４Ｂは折返し縁２４Ａから左上方に延在し、下側部２４Ｃは折返し縁２４Ａから左下方に延在して形成される。 The folded edge 23A of the tissue paper 23 laminated adjacent to the upper side of the tissue paper 22 is located on the right side, the upper portion 23B extends from the folded edge 23A to the upper left, and the lower portion 23C extends from the folded edge 23A to the lower left. The folded edge 24A of the tissue paper 24 formed so as to extend toward the lower side of the tissue paper 22 and laminated adjacent to the lower side of the tissue paper 22 is located on the right side, and the upper portion 24B extends from the folded edge 24A to the upper left. The lower side portion 24C is formed so as to extend downward to the left from the folded edge 24A.
　ティシュペーパー２２の上側部２２Ｂは、ティシュペーパー２３の上側部２３Ａと下側部２３Ｂの間に挿入され、ティシュペーパー２２の下側部２２Ｃは、ティシュペーパー２４の上側部２４Ａと下側部２４Ｂの間に挿入されている。これにより、ティシュペーパー束２０の最も上側に位置するティシュペーパー２１を上側に引上げると、この下側に隣接するティシュペーパー２１が上側に引上げることができる。 The upper portion 22B of the tissue paper 22 is inserted between the upper portion 23A and the lower portion 23B of the tissue paper 23, and the lower portion 22C of the tissue paper 22 is the upper portion 24A and the lower portion 24B of the tissue paper 24. It is inserted in between. As a result, when the tissue paper 21 located on the uppermost side of the tissue paper bundle 20 is pulled up, the tissue paper 21 adjacent to the lower side can be pulled up.
　また、ティシュペーパー２２の折返し縁２２Ａは、フィルム包装ティシュー１０の第４面１４に沿って左右方向に沿って延在し、ティシュペーパー２３の折返し縁２３Ａとティシュペーパー２４の折返し縁２４Ａは、フィルム包装ティシュー１０の第３面１３に沿って延在する。よって、フィルム包装ティシュー１０の第５面１５又は第６面１６に対して垂直方向の圧縮荷重が加わった場合の変位量（圧縮量）を小さくすることができる。なお、本明細書では、理解を容易にするために、ティシュペーパー２１を、ティシュペーパー２２，２３，２４と付して説明した。 Further, the folded edge 22A of the tissue paper 22 extends along the fourth surface 14 of the film packaging tissue 10 in the left-right direction, and the folded edge 23A of the tissue paper 23 and the folded edge 24A of the tissue paper 24 are films. It extends along the third surface 13 of the packaging tissue 10. Therefore, the amount of displacement (compression amount) when a compressive load in the direction perpendicular to the fifth surface 15 or the sixth surface 16 of the film packaging tissue 10 is applied can be reduced. In this specification, Tish Paper 21 is referred to as Tish Paper 22, 23, 24 for easy understanding.
　ティシュペーパー２１を構成する薄葉紙の原料パルプとしては、ＮＢＫＰとＬＢＫＰとを配合したものである。古紙パルプが配合されていてもよいが、風合いなどの点で、ＮＢＫＰとＬＢＫＰのみから構成されているのがよい。配合割合としては、ＮＢＫＰ：ＬＢＫＰ＝２０：８０～８０：２０がよく、特に、ＮＢＫＰ：ＬＢＫＰ＝３０：７０～６０：４０が好ましい。 The raw material pulp for thin paper that constitutes Tish Paper 21 is a mixture of NBKP and LBKP. Although used paper pulp may be blended, it is preferable that it is composed of only NBKP and LBKP in terms of texture and the like. As the blending ratio, NBKP: LBKP = 20: 80 to 80:20 is preferable, and NBKP: LBKP = 30: 70 to 60:40 is particularly preferable.
　ティシュペーパー２１の各プライを構成する薄葉紙１枚あたりの坪量は１０～２５ｇ／ｍ2である。好ましくは、１０～１８ｇ／ｍ2である。ここでの坪量は、ＪＩＳ Ｐ ８１２４（１９９８）の測定方法によるものをいう。また、ティシュペーパー２１の紙厚は、２プライの状態で９０～２００μｍであり、好ましくは９０～１４０μｍである。３プライの状態で１２０～３００μｍである。ここでの紙厚は、試験片をＪＩＳ Ｐ ８１１１（１９９８）の条件下で十分に調湿した後、同条件下でダイヤルシックネスゲージ（厚み測定器）「ＰＥＡＣＯＣＫ Ｇ型」（株式会社尾崎製作所製）及びその相当機を用いて複数プライの状態で測定した値をいう。 The basis weight per thin paper sheet constituting each ply of the tissue paper 21 is 10 to 25 g / m 2 . Preferably, it is 10-18 g / m 2. The basis weight here refers to the measurement method of JIS P 8124 (1998). The thickness of the tissue paper 21 is 90 to 200 μm, preferably 90 to 140 μm in the 2-ply state. It is 120 to 300 μm in the state of 3 plies. The paper thickness here is determined by adjusting the humidity of the test piece sufficiently under the conditions of JIS P 8111 (1998), and then under the same conditions, dial thickness gauge (thickness measuring instrument) "PEACOCK G type" (manufactured by Ozaki Seisakusho Co., Ltd.). ) And its equivalent machine, it means the value measured in the state of multiple plies.
　＜包装フィルム＞
　図４，５に示すように、包装フィルム３０は、平面形状のフィルムを左右方向の両側に開口部３１が形成されるように前後方向の縦断面において略矩形状に巻込み、巻込み方向における一側端部と他側端部が重なる重畳部３２における中間部３３を融着処理して形成される。これにより、平面形状のフィルムを筒体３４に形成して、筒体３４の一側に形成された開口部３１からティシュペーパー束２０を筒体３４の内側に挿入することができる。なお、本実施形態においては、第３面１３に重畳部３２が位置するように巻込まれている。 <Packaging film>
As shown in FIGS. 4 and 5, the packaging film 30 winds a flat film in a substantially rectangular shape in a vertical cross section in the front-rear direction so that openings 31 are formed on both sides in the left-right direction, and in the winding direction. It is formed by fusing the intermediate portion 33 in the overlapping portion 32 where the one side end portion and the other side end portion overlap. As a result, a flat film can be formed on the tubular body 34, and the tissue paper bundle 20 can be inserted into the tubular body 34 through the opening 31 formed on one side of the tubular body 34. In this embodiment, the superimposing portion 32 is wound so as to be located on the third surface 13.
　次に、筒体３４のティシュペーパー束２０の左部よりも左側に延在する延在部３５は、キャラメル包装に折畳まれている。すなわち、延在部３５の上側部３５Ａを下側に折曲げ、次に、前側部３５Ｂと後側部３５Ｃをそれぞれ後側と前側に折曲げ、次に、下側部３５Ｄを上側に折曲げて融着処理して開口部３１を塞いでフィルム包装ティシュー１０の第５面１５が形成されている。これにより、ピロー包装に比較してフィルムが４層に積層されて形成された第５面１５は、剛性が強くなり、第５面１５に圧縮荷重が加わった場合の変位量を抑制することができる。なお、ピロー包装とは、延在部３５の上側部３５Ａと下側部３５Ｄの端部を重ね合わせて融着処理して開口部３１を塞ぐ形態である。 Next, the extending portion 35 extending to the left side of the left portion of the tissue paper bundle 20 of the cylinder 34 is folded into a caramel package. That is, the upper portion 35A of the extending portion 35 is bent downward, then the front side portion 35B and the rear side portion 35C are bent to the rear side and the front side, respectively, and then the lower side portion 35D is bent upward. The fifth surface 15 of the film packaging tissue 10 is formed by the fusion treatment to close the opening 31. As a result, the fifth surface 15 formed by laminating four layers of the film as compared with the pillow packaging has higher rigidity, and the amount of displacement when a compressive load is applied to the fifth surface 15 can be suppressed. it can. The pillow packaging is a form in which the upper portion 35A of the extending portion 35 and the end portion of the lower portion 35D are overlapped and fused to close the opening 31.
　同様に、筒体３４のティシュペーパー束２０の右部よりも右側に延在する延在部３７は、キャラメル包装に折畳まれている。すなわち、延在部３７の上側部３７Ａを下側に折曲げ、次に、前側部３７Ｂと後側部３７Ｃをそれぞれ後側と前側に折曲げ、次に、下側部３７Ｄを上側に折曲げて開口部３１を塞いでフィルム包装ティシュー１０の第６面１６が形成されている。これにより、ピロー包装に比較してフィルムが４層に積層されて形成された第６面１６は、剛性が強くなり、第６面１６に圧縮荷重が加わった場合の変位量を抑制することができる。 Similarly, the extending portion 37 extending to the right side of the right portion of the tissue paper bundle 20 of the cylinder 34 is folded into a caramel package. That is, the upper portion 37A of the extending portion 37 is bent downward, then the front side portion 37B and the rear side portion 37C are bent to the rear side and the front side, respectively, and then the lower side portion 37D is bent upward. The sixth surface 16 of the film packaging tissue 10 is formed by closing the opening 31. As a result, the sixth surface 16 formed by laminating the film in four layers has higher rigidity than the pillow packaging, and the amount of displacement when a compressive load is applied to the sixth surface 16 can be suppressed. it can.
　フィルム包装ティシュー１０の外装を構成する柔軟性のある樹脂製の包装フィルム３０の具体例としては、ポリエチレンフィルム、ポリプロピレンフィルム、ポリエステルフィルム、ポリエチレンテレフタレートフィルム、ナイロンフィルム、塩化ビニリデンフィルム、エチレンビニルアルコール共重合体の単層フィルム、または、それらのフィルムを含む適宜積層されたラミネートフィルムや、それらのフィルムにアルミ蒸着などの表面処理を施したガスバリアフィルムが例示できる。また、サトウキビ、芋（デンプン）、トウモロコシといった植物原料に由来するバイオマスフィルムを用いることもできる。このようなバイオマスフィルムの使用は、環境保護の観点から好ましい。
　コストの観点からはポリプロピレンフィルム、ポリエチレンフィルムが好適である。また、包装フィルム３０は、意匠性や手触り性に優れる梨地フィルムであってもよい。さらに、香り付きのティシュペーパーなど臭気のあるものを包装するのであれば、保香性に優れるエチレンビニルアルコール共重合体樹脂フィルム、ポリエチレンテレフタレート樹脂フィルムが好まし。エチレンビニルアルコール共重合体樹脂フィルム、ポリエチレンテレフタレート樹脂フィルムの一方面または両面に、ポリエチレン樹脂製フィルムやポリプロピレン樹脂製フィルムを積層して熱融着性が高められた複層の樹脂フィルムであってもよい。 Specific examples of the flexible resin packaging film 30 constituting the exterior of the film packaging tissue 10 include polyethylene film, polypropylene film, polyester film, polyethylene terephthalate film, nylon film, vinylidene chloride film, and ethylene vinyl alcohol co-weight. Examples thereof include a combined single-layer film, an appropriately laminated laminated film containing those films, and a gas barrier film obtained by subjecting these films to a surface treatment such as aluminum vapor deposition. In addition, biomass films derived from plant raw materials such as sugar cane, potato (starch), and corn can also be used. The use of such a biomass film is preferable from the viewpoint of environmental protection.
From the viewpoint of cost, polypropylene film and polyethylene film are preferable. Further, the packaging film 30 may be a satin-finished film having excellent design and touch. Furthermore, when packaging odorous materials such as scented tissue paper, ethylene vinyl alcohol copolymer resin film and polyethylene terephthalate resin film, which have excellent aroma retention properties, are preferable.

　図６に示すように、ガセット包装袋５０は、チューブ状のフィルム６０の左側部６１と右側部６２をそれぞれ内側に折込んで折畳み部を有する偏平形状のチューブ状のフィルム６０から形成される。これにより、チューブ状のフィルム６０の上部に形成された開口部６３と下部に形成された開口部６４を熱融着して塞ぐと、チューブ状のフィルム６０の上部と下部にガセットを形成することができる。 As shown in FIG. 6, the gusset packaging bag 50 is formed of a flat tube-shaped film 60 having a folded portion by folding the left side portion 61 and the right side portion 62 of the tube-shaped film 60 inward, respectively. As a result, when the opening 63 formed in the upper part of the tubular film 60 and the opening 64 formed in the lower part are heat-sealed and closed, gussets are formed in the upper part and the lower part of the tubular film 60. Can be done.
　図７（ａ）に示すように、チューブ状のフィルム６０の上部の開口部６３を所定の長さに亘って熱融着して塞ぎ天面５１と天面５１の上側に連続する把手部５７を形成する。なお、把手部５７には、左右方向に沿って長軸を有する指かけ孔５８が形成されている。 As shown in FIG. 7A, the upper opening 63 of the tubular film 60 is heat-sealed over a predetermined length to close the top surface 51 and the handle portion 57 continuous above the top surface 51.

　チューブ状のフィルム６０としては、ポリプロピレンフィルム及びポリエチレンフィルムであるのがコスト面及び開封性の点で好ましい。フィルムの融点は１５０℃以下であるのがよい。なお、包装フィルムの融点が低いほうが低温で熱融着処理でき、封止や把手部の形成において好ましいが、過度に融点が低い場合には、フィルム包装ティシュー１の特に妻面４Ａの四角部分４ｔとの摩擦などによって傷が付いたり、穴が空くおそれが高まるので、実質的な下限値は８０℃である。ポリエチレンフィルムとしては、直鎖低密度ポリエチレンフィルム（ＬＬＤＰＥ）、低密度ポリエチレンフィルム（ＬＤＰＥ）、中密度ポリエチレンフィルム（ＭＤＰＥ）が挙げられる。なかでも、本発明においては、熱融着性及びコストの点で、密度０．９１０～０．９４０ｇ／ｃｍ3で融点が１１０～１２０℃の直鎖低密度ポリエチレンフィルム層（ＬＬＤＰＥ）が、特に適する。また、ポリエチレンテレフタレートフィルム、ナイロンフィルム、塩化ビニリデンフィルム、エチレンビニルアルコール共重合体の単層フィルム、または、それらのフィルムを含む適宜積層されたラミネートフィルムや、それらのフィルムにアルミ蒸着などの表面処理を施したガスバリアフィルムを用いてもよい。包装フィルム４と同様に、サトウキビ、芋（デンプン）、トウモロコシといった植物原料に由来するバイオマスフィルムを用いることもできる。ガセット包装フィルムにバイオマスフィルムを使用するのも、環境保護の観点から好ましい。
　チューブ状のフィルム６０の厚さは、柔軟性、コスト、包装時における熱融着性に加えて、開封時に容易に開封できる引裂き性、内包されるフィルム包装ティシュー１の特に妻面四角部４ｔに対する耐摩耗性、さらに把手部に設けられた指かけ孔に指を通して持ち運ぶ際に指に過度の負荷がかからない柔軟性等、ガセット包装特有の事情に加えて内包されるフィルム包装ティシュー１との関係を考慮して適宜に選択する。 As the tube-shaped film 60, polypropylene film and polyethylene film are preferable in terms of cost and openability. The melting point of the film is preferably 150 ° C. or lower. It should be noted that a packaging film having a low melting point can be heat-sealed at a low temperature, which is preferable in sealing and forming a handle, but when the melting point is excessively low, the square portion 4t of the film packaging tissue 1 in particular, the end surface 4A. The actual lower limit is 80 ° C. because there is a high possibility that the film will be scratched or a hole will be formed due to friction with the film. Examples of the polyethylene film include a linear low density polyethylene film (LLDPE), a low density polyethylene film (LDPE), and a medium density polyethylene film (MDPE). Among them, in the present invention, a linear low density polyethylene film layer (LLDPE) having a density of 0.910 to 0.940 g / cm 3 and a melting point of 110 to 120 ° C. is particularly preferable in terms of heat fusion property and cost.

An applied gas barrier film may be used. Similar to the packaging film 4, a biomass film derived from a plant material such as sugar cane, potato (starch), and corn can also be used. It is also preferable to use a biomass film for the gusset packaging film from the viewpoint of environmental protection.
The thickness of the tubular film 60 is, in addition to flexibility, cost, and heat-sealing property at the time of packaging, tearability that can be easily opened at the time of opening, and the included film packaging tissue 1 with respect to the square portion 4t of the end surface. In addition to the circumstances peculiar to gusset packaging, such as wear resistance and flexibility that does not put an excessive load on the finger when carrying it through the finger hook hole provided in the handle, the relationship with the included film packaging tissue 1 Select as appropriate in consideration.
　このような点から好ましいチューブ状のフィルム６０の厚み及びソフトネスは、ＪＩＳ　Ｐ　８１１８（１９９８）に準拠して測定される厚みが１０～６５μｍ、ＪＩＳ　Ｌ　１０９６（２０１０）　Ｅ法に準じたハンドルオメータ法に基づいて測定されるソフトネスが５．０～５０．０ｃＮである。 From this point of view, the thickness and softness of the tube-shaped film 60 are preferably 10 to 65 μm measured in accordance with JIS P 8118 (1998), and a handle according to JIS L 1096 (2010) E method.

　＜フィルム包装ティシュー集合包装体＞
　図１に示すように、本実施形態のフィルム包装ティシュー集合包装体１は、ガセット包装袋５０の内部に、５個のフィルム包装ティシュー１０が並列して挿入されている。 <Film packaging tissue assembly packaging>
As shown in FIG. 1, in the film packaging tissue assembly package 1 of the present embodiment, five film packaging tissue 10s are inserted in parallel inside the gusset packaging bag 50.
　フィルム包装ティシュー１０は、フィルム包装ティシュー集合包装体１の天面５１と底面５２に、それぞれフィルム包装ティシュー１０の第６面１６と第５面１５を対向させ、フィルム包装ティシュー集合包装体１の正面５３と裏面５４に、それぞれフィルム包装ティシュー１０の第３面１３と第４面１４を対向させ、フィルム包装ティシュー集合包装体１の左側面５５と右側面５６に、それぞれフィルム包装ティシュー１０の第１面１１と第２面１２を対向させる姿勢で挿入されている。これにより、フィルム包装ティシュー集合包装体１の上側に、フィルム包装ティシュー集合包装体１を段積みした場合に、フィルム包装ティシュー１０の第６面１６に作用する圧縮荷重を、高い剛性を有する第６面１６を介してティシュペーパー束２０の対向面の全面に均等な分布することができ、フィルム包装ティシュー集合包装体１の上側に、複数のフィルム包装ティシュー集合包装体１を段積みすることができる。 The film packaging tissue 10 has the sixth surface 16 and the fifth surface 15 of the film packaging tissue 10 facing each other on the top surface 51 and the bottom surface 52 of the film packaging tissue assembly package 1, respectively, and the front surface of the film packaging tissue assembly package 1. The third surface 13 and the fourth surface 14 of the film packaging tissue 10 face each other on the back surface 54 and the back surface 54, respectively, and the first surface of the film packaging tissue 10 is placed on the left side surface 55 and the right side surface 56 of the film packaging tissue assembly package 1, respectively. The surface 11 and the second surface 12 are inserted so as to face each other. As a result, when the film packaging tissue assembly packaging 1 is stacked on the upper side of the film packaging tissue assembly packaging 1, the compressive load acting on the sixth surface 16 of the film packaging tissue 10 is applied to the sixth surface 16 having high rigidity. A plurality of film packaging tissue assembly packages 1 can be stacked on the upper side of the film packaging tissue assembly package 1 so that the tissue paper bundle 20 can be evenly distributed over the entire surface of the facing surfaces of the tissue paper bundle 20 via the surface 16. ..
　フィルム包装ティシュー１０とガセット包装袋５０から形成された本実施形態のフィルム包装ティシュー集合包装体１の天面５１の左右方向の長さは略１９０ｍｍ、天面５１の前後方向の長さは略９８．５ｍｍであり、正面５３の上下方向の長さは略１７８ｍｍに形成され、その重量は６００ｇに形成されている。 The length of the top surface 51 of the film packaging tissue assembly package 1 of the present embodiment formed of the film packaging tissue 10 and the gusset packaging bag 50 in the left-right direction is approximately 190 mm, and the length of the top surface 51 in the front-rear direction is approximately 98 mm. It is 5.5 mm, the length of the front surface 53 in the vertical direction is formed to be approximately 178 mm, and its weight is formed to be 600 g.
　フィルム包装ティシュー集合包装体１の左側面５５と右側面５６の法線方向の圧縮率は、８５～１２５％に形成され、８５～１００％に形成するのが好ましい。これにより、フィルム包装ティシュー１０と隣接するフィルム包装ティシュー１０を所定の間隔に維持して、フィルム包装ティシュー１０の左右方向の傾きを防止して、圧縮荷重に対する耐力の低下を防止することができる。 The compressibility of the left side surface 55 and the right side surface 56 of the film packaging tissue assembly package 1 in the normal direction is formed to be 85 to 125%, and preferably 85 to 100%. As a result, the film packaging tissue 10 adjacent to the film packaging tissue 10 can be maintained at a predetermined interval to prevent the film packaging tissue 10 from tilting in the left-right direction, thereby preventing a decrease in the yield strength against a compressive load.
　圧縮率が１２５％超の場合は、フィルム包装ティシュー集合包装体１の内部に５個のフィルム包装ティシュー１０を挿入することができない恐れがある。一方、８５％未満の場合には、フィルム包装ティシュー１０と、隣接するフィルム包装ティシュー１０の間の間隔が広くなり、一部のフィルム包装ティシュー１０が傾斜してフィルム包装ティシュー１０の並列姿勢が乱れ圧縮荷重に対する耐力が低下する。 If the compression ratio exceeds 125%, it may not be possible to insert the five film packaging tissuees 10 inside the film packaging tissue assembly package 1. On the other hand, when it is less than 85%, the distance between the film packaging tissue 10 and the adjacent film packaging tissue 10 becomes wide, and a part of the film packaging tissue 10 is tilted and the parallel posture of the film packaging tissue 10 is disturbed. The yield strength against compressive load decreases.
　フィルム包装ティシュー集合包装体１の左側面５５と右側面５６の法線方向の圧縮率は、フィルム包装ティシュー集合包装体１に挿入された５個のフィルム包装ティシュー１０の最も左側に位置するフィルム包装ティシュー１０の第１面１１と最も右側に位置するフィルム包装ティシュー１０の第２面１２の間の長さを、フィルム包装ティシュー集合包装体１の左側面５５と右側面５６の長さ、すなわち、正面５３の左右方向の長さで割って得られた値に、１００を掛けて算出した値である。 The compression ratio in the normal direction of the left side surface 55 and the right side surface 56 of the film packaging tissue package 1 is the film packaging located on the leftmost side of the five film packaging tissue 10 inserted into the film packaging tissue assembly package 1. The length between the first surface 11 of the tissue 10 and the second surface 12 of the film packaging tissue 10 located on the far right side is the length of the left side surface 55 and the right side surface 56 of the film packaging tissue assembly packaging 1, that is, It is a value calculated by multiplying the value obtained by dividing the length of the front surface 53 in the left-right direction by 100.
　最も左側に位置するフィルム包装ティシュー１０の第１面１１と最も右側に位置するフィルム包装ティシュー１０の第２面１２の間の長さは、それぞれのフィルム包装ティシュー１０の第１面１１と第２面１２の間の長さ、すなわち第３面１３の左右方向の長さを測定して合計して求めた。 The length between the first surface 11 of the film packaging tissue 10 located on the leftmost side and the second surface 12 of the film packaging tissue 10 located on the rightmost side is the first surface 11 and the second surface 12 of the film packaging tissue 10 located on the far right side, respectively. The length between the surfaces 12, that is, the length of the third surface 13 in the left-right direction was measured and summed up.
　フィルム包装ティシュー１０の第３面１３の左右方向の長さは、フィルム包装ティシュー１０の第１面１１を上側にした姿勢で定盤に置き、ダイヤルゲージ等の高さゲージで測定して求めた。また、フィルム包装ティシュー集合包装体１の正面５３の左右方向の長さは、ノギス等の長さゲージで測定して求めた。 The length of the third surface 13 of the film packaging tissue 10 in the left-right direction was determined by placing it on a surface plate with the first surface 11 of the film packaging tissue 10 facing up and measuring it with a height gauge such as a dial gauge. .. Further, the length of the front surface 53 of the film packaging tissue assembly package 1 in the left-right direction was determined by measuring with a length gauge such as a caliper.
