Description

Film packaging Tissue collective packaging

The present invention relates to a film packaging tissue assembly package in which a plurality of film packaging tissue obtained by folding and stacking tissue paper bundles and packaging them with a flexible packaging film are gusseted.

A well-known box is a tissue paper package (hereinafter, also referred to as a box product), which is also called a box tissue in which a bundle of tissue paper is contained in a paper storage box called a carton box.
Since this box product 101B is excellent in shape stability of the paper storage box which is the outer shell, as shown in FIG. 12, generally five or three pieces are arranged so as to be stacked in the nadir direction, and the exterior It is a product form 110B of collective packaging (also called pack packaging) bundled by film 111, and is often sold in piles at stores and the like.

On the other hand, as a tissue paper package, a tissue paper package in which a bundle of tissue paper is wrapped with a flexible resin packaging film, which is also called a film packaging tissue, is known. As this film packaging tissue, a pocket tissue that is suitable for carrying is well known, but like box products, it is not portable that is used stationary or for refilling a bundle of box products. There is also a film packaging tissue.
The film packaging tissue used for stationary or the like like this box product has advantages in terms of transportation cost and portability due to reduction of packaging materials and compactness as compared with the box product. However, this type of film packaging tissue is inferior in shape retention to box products because a bundle of flexible tissue paper is wrapped in flexible packaging film, and like box products, a plurality of films are simply stacked to form a film. There is a problem that shape retention suitable for over-the-counter stacking cannot be obtained only by collective packaging in.

In view of these problems, in the technique shown in Patent Document 1 below, intake and exhaust holes are formed in the film packaging tissue to make the film packaging tissue compressible, and the gusset is restrained by the collective packaging film in the compressed state. By collective wrapping with packaging, the shape retention is improved as a whole like a box product, making it suitable for stacking in stores.

Japanese Unexamined Patent Publication No. 2018-058654

However, if such a compressed state is maintained for a long period of time, the fluffy feeling of the tissue paper may decrease. In particular, the risk is further increased in a tissue paper having a high water content such as a moisturizing tissue containing a chemical solution or in a high humidity environment.

On the other hand, for the collective packaging of film packaging tissue, gusset packaging suitable for flexible objects to be packaged such as toilet rolls is preferable. In addition, the collective wrapping body of the film wrapping tissue, which is different from the portable one and is mainly used for stationary use, is not usually large enough to fit in a bag and has a certain weight. Gusset packaging with a handle is preferred.
However, in this gusset packaging, spaces are likely to be formed on the top surface side and the bottom surface side in particular, so if the compressibility of the film packaging tissue is lowered and the restraint is simply lowered, the included film packaging tissue is easy to move. Become. In the film packaging tushoe, the sealing portion formed by heat fusion of the packaging film is hard, so when the included film packaging tissue is easy to move, the hard portion and the exterior film constituting the gusset packaging are formed. Is rubbed and the risk of breakage increases.

Therefore, the main problem of the present invention is that it is difficult to reduce the fluffy feeling of the included tissue paper in the collective packaging of the film packaging tissue that is mainly used as a box product, and the product is sold in piles in stores. It is an object of the present invention to provide a film packaging tissue assembly package which is excellent in shape retention that is easy to equalize and whose collective packaging film is not easily damaged. Further, the present invention also provides a film packaging tissue collective packaging body which is excellent in the ease of taking out of the encapsulated film packaging tissue and also excellent in the opening property and portability of the collective packaging body.

Hereinafter, the present invention will be described with reference to FIGS. 1 to 10 which are embodiments and FIG. 11 which is a comparative embodiment.

The film-wrapping tissue shoe assembly 10 according to the present invention (hereinafter, also referred to as an assembly package) is a film-wrapping tissue 1 in which a bundle 3 obtained by folding and stacking a plurality of sets of tissue paper 2 is packaged by a flexible packaging film 4. However, a plurality of them are arranged and gusset-wrapped so as to be included in a gusset wrapping bag 13 having a handle portion 45 on the top surface side.

The film packaging tissue 1 according to the present invention is a bundle 3 that is overlap-wrapped. The overlap wrapping is a wrapping form also called caramel wrapping or combined wrapping, and as shown in FIGS. 3 to 5, the bundle 3 to be packaged is formed by a wrapping film 4 with openings 4Z at both ends in the longitudinal direction. The part 4X that overlaps in the winding direction is bonded by a fusion treatment or an adhesive, and the part 4Y that extends beyond the bundle 3 is wrapped around the bundle 3 so as to be wound into a tubular shape. Fold it from the vicinity of one edge to the end face side of the bundle 3, and at least the tip edges of the substantially triangular or substantially trapezoidal pieces formed at that time are overlapped and bonded by a fusion treatment or an adhesive to form a cylinder. This is a packaging mode in which the opening 4Z is sealed to form the end surface 4A.

In this overlap packaging, since the end surface 4A has a substantially flat shape, the exterior of the packaging film 4 has a substantially straight hexahedron shape close to that of a box. Further, since the end surface 4A is formed by stacking a plurality of layers of the packaging film 4 and adhering them to each other, the rigidity is high, and the shape of a substantially straight hexahedron is easily maintained without being crushed.
Therefore, if the film packaging tissue 1 is overlap-wrapped, the product shape is a substantially straight hexahedron. Therefore, as shown in FIGS. 1 and 2, even when the film packaging tissue 1 is arranged and collectively packaged, the overall straight hexahedron shape is formed. Can be. For this reason, it is easy to stack the collective packages in multiple stages in an aligned manner, and it is easy to stack them in stores and sell them. Further, even if they are stacked in this way, the rigidity of the exterior due to the packaging film 4 is high, so that it is difficult for a compressive force to be applied to the inner bundle 3, and the fluffy feeling of the tissue paper 2 is unlikely to decrease.

It is desirable that the bundle 3 of tissue paper contained in the film packaging tissue 1 is a pop-up type. As shown in FIG. 7, the pop-up type bundle 3 is formed by folding a substantially rectangular tissue paper 2 having a length of 197 ± 10 mm and a width of 217 ± 10 mm in half, and the other bundles 3 located above and below the folded inner side 2A. A plurality of tissue papers 2 are folded and laminated so that the folded piece 2B of the tissue paper 2 is located. When one folded piece located at the highest position is pulled upward, it is adjacent immediately below the folded piece. The other folded piece 2B is dragged upward and lifted. Such a bundle 3 can be manufactured by a known multi-stand type or rotary type interfolder. The bundle 3 according to the present invention may be a non-pop-up type having a substantially rectangular parallelepiped shape in which a plurality of sets of tissue papers 2 are folded and laminated.

The pop-up type bundle 3 has a pair of longitudinal side surfaces 3B in which the folded edges 2C of each tissue paper 2 are lined up, and a pair of short side surfaces 3A in which the folded edges 2C are not lined up, and further has a short side surface 3A and a longitudinal surface. It has a substantially rectangular parallelepiped shape having a pair of planes (upper and lower surfaces) 3C connected to the side surface 3B. Further, since it is composed of soft tissue paper 2, it is flexible and easily compressed and deformed.

The number of sets of tissue paper 2 constituting the bundle 3 is not limited, but is generally 120 to 240 sets with 2 plies (2 sheets stacked) or 3 plies (3 sheets stacked) as one set. The size of the bundle 3 is not necessarily limited, but is a bundle of 150 sets of 2-ply tissue paper, which is approximately 40 to 50 mm in height × 160 to 200 mm in the longitudinal direction (width) × 90 in the lateral direction (depth). It is about 110 mm. As shown in this shape, the film packaging tissue 1 according to the present invention is a portable tissue paper having a height of about 10 mm and 10 to 12 sets of included tissue paper, so-called pocket tissue. Not for use.

In the film wrapping tissue 1 of the illustrated form, the end face 4A formed by sealing the cylinder opening 4Z is positioned to face the short side surface 3A of the bundle 3, and the top of the bundle 3 of the wrapping film 4 is located. A perforation for opening 5 is formed at a position facing the tissue paper 2. In particular, in the film-wrapped tissue paper 1 of the illustrated form, a plurality of folded pieces 2B of the other tissue paper 2 located above and below are located on the folded inner side 2A of the tissue paper 2 folded in half. A bundle 3 of a pop-up type substantially rectangular parallelepiped-shaped tissue paper 2 in which the tissue paper 2 is folded and laminated is overlap-wrapped, and has an outlet forming portion 5 for the tissue paper on the upper surface, and the folded edge 2C of the bundle 3 is provided. The end surface 4A, which is the sealing portion of the cylinder opening 4X, is located facing the short side surface 3A where the two are not lined up.

When the bundle 3 is a pop-up type as shown in this illustrated form, when the uppermost tissue paper 2 of the bundle 3 is pulled out by forming an opening, a part of the next tissue paper located immediately below the opening is opened. It will be more exposed. Further, the film packaging tissue 1 configured in this way has a structure in which the tissue paper is laminated in the direction in which the highly rigid end surface 4A stands up, so that a compressive force is applied from the bundle lamination direction (vertical direction). However, the bundle 3 is hard to be compressed, and the fluffy feeling is hard to be lowered.
The film packaging tissue 1 may be provided with intake / exhaust holes communicating with the inside and the outside in order to prevent bursting when an external pressure is applied. An intake / exhaust hole may be provided on the end surface 4A facing the short side surface 3A where the folded edges 2C of the bundle 3 of the packaging film 4 are not lined up, but it is desirable that there is no intake / exhaust hole at this position. If the intake / exhaust holes are provided on the end surface 4A, the vulnerability of the end surface 4A is increased, so that the advantage of the overlap packaging having the end surface 4A having high rigidity is reduced.

As shown in FIG. 3, the outlet forming portion 5 may be a linear opening perforation 5 extending in the longitudinal direction in the central portion in the lateral direction, but is along the longitudinal direction as shown in FIG. Perforations may be formed in an elongated ring shape to form an elongated opening. Although not shown, the opening perforation 5 may be covered with a peelable sealing material.
In particular, as a suitable shape of the outlet forming portion 5, as shown in FIG. 5, in the central portion in the lateral direction, the slit portion 51 extending in the longitudinal direction and the end portion of the slit portion 51 are communicated with each other. It is desirable to form a shape having an opening 50 having a widening portion 52 that gradually widens as the distance from the slit portion 51 in the longitudinal direction increases. Further, it is desirable that the opening 50 has a shape in which the widening portion 52 has a curved portion 53 that continuously bulges toward the end in the longitudinal direction. In this case, the length L3 of the existing portion of the outlet forming portion 5 is shorter than the longitudinal length L4 of the bundle 3, and is generally 60 to 80% of the longitudinal length L4 of the bundle 3.
The width (length in the lateral direction) of the slit portion 51 is 10 mm or less, preferably 7 mm or less in the lateral direction. As shown in FIG. 5B, the width formed by opening the linear perforations may be substantially small.
If the outlet is formed in the shape of the outlet forming portion 5, the vicinity of the edge 51A of the slit portion 51 becomes a free edge piece that can easily move in the vertical direction, so that a set of tissue paper is pulled out from the bundle. In some cases, the edge piece deforms in the direction in which it is pulled out, and it leans against the next set of exposed tissue paper. In addition, the next tissue paper, which is partially exposed from the take-out port, following the tissue paper pulled out from the bundle, is deformed into a highly erect shape because its longitudinal edge is wound along the edge of the curved portion. It becomes easy. At the opening perforations shown in FIG. =, it is difficult for the tissue paper to fall into the internal space, which is likely to occur in the overlapping packaging in which the exterior has a straight hexahedron shape.
The cut tie ratio of the perforations forming the outlet forming portion 5 can be appropriately determined depending on the ease of breaking of the film to be used, but as a preferable example, the length of the cut portion is 0.8 mm. It is 5.0 mm or more and the length of the tie portion is 0.3 mm or more and 5.0 mm or less. Further, in the outlet forming portion 5 shown in FIG. 5, not all are formed by perforations, but slit portions and widening portions are formed by perforations, and a part of the curved portion (in the illustrated example, the longitudinal direction) is formed. It is preferable to form by slit cutting provided with an uncut portion at the end). It becomes easier to open the outlet from the curved part.

Specific examples of the flexible resin packaging film 4 constituting the exterior of the film packaging tissue 1 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 these 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 desirable from the viewpoint of environmental protection.
From the viewpoint of cost, polypropylene film and polyethylene film are preferable. Further, the packaging film 4 may be a satin-finished film having excellent design and touch. Further, when wrapping odorous materials such as scented tissue paper, ethylene vinyl alcohol copolymer resin film and polyethylene terephthalate resin film having excellent fragrance retention are desirable. Even if it is a multi-layered resin film in which a polyethylene resin film or a polypropylene resin film is laminated on one or both sides of an ethylene vinyl alcohol copolymer resin film or a polyethylene terephthalate resin film to improve heat-sealing properties. Good.

The thickness of the packaging film 4 may be appropriately selected in consideration of flexibility, cost, gas permeability, and heat-sealing property at the time of packaging, but is preferably measured in accordance with JIS P 8118 (1998). It is desirable that the thickness is 25 to 75 μm and the softness measured based on the handle ometer method according to the JIS L 1096 (2010) E method is 5.0 to 50.0 cN. If the thickness is 25 to 75 μm, the rigidity of the end surface 4A is sufficiently increased. Further, with such a thickness and softness, the packaging film 4 is not easily torn, and it is easy to make the tissue paper easy to take out, particularly to have excellent pop-up property. The thickness of the measurement sample is determined by adjusting the humidity of the measurement sample sufficiently under the conditions of JIS P8111 (1998), and then dial thickness gauge (thickness measuring instrument) "PEACOCK G-1A type" (manufactured by Ozaki Seisakusho Co., Ltd.) and its equivalent. Measure using a machine.

In the film packaging tissue assembly package 10 according to the present invention, a plurality of overlapping film packaging tissue 1s face each other in the gusset packaging bag 13 with the end surface 4A facing the top surface side and the top surface side where the handle portion is located. It is gusset-wrapped so that the longitudinal direction is along the top-bottom direction toward the bottom side.

The gusset packaging contains the object to be packaged in a bag-like space between the

adhesive portions

41 and 42 due to heat fusion on the nadir side, and particularly has

gusset portions

43 and 43 between the front surface and the back surface. It is a packaging form. In the gusset packaging, for example, as shown in FIGS. 8 and 9, the

side portions

40E and 40E of the tubular gusset packaging film 14 also called the gusset tube 40 are folded inside the bag to flatten the top surface side of the gusset tube. A gusset packaging bag precursor in which the opening on the top surface side is sealed as the top surface side sealing portion 41 and the handle portion 45 is formed, and then only the top surface side is sealed. The bottom side opening 40X of the body is widened, and the object to be packaged (

film packaging tips

1, 1 ... In the illustrated form) is inserted from there, and then the bottom side is also heat-sealed by an appropriate sealing means such as heat fusion. It is manufactured so as to be sealed to form a lower sealing portion 42. In the gusset packaging, the gusset packaging bag 13 as an exterior has

gusset portions

43, 43 formed by opening the

side portions

40E, 40E folded in a flat state, and each surface connected to the gusset portion 43. .. The second surfaces connected to the

gusset portions

43 and 43 are the front surface 46 and the back surface 46, but the front surface 46 and the back surface 46 are relative to each other, and which surface is the front surface is limited. It is not something that is done.

The handle portion 45 is provided on the top surface side of the top surface side sealing portion 41 which is the boundary on the top surface side with the bag portion containing the film packaging tissue 1 in order to improve the portability of the collective package. It is a surplus part. In the illustrated form, a finger hook hole 47 is formed. When the finger hook hole 47 is formed in the handle portion 45 in this way, the portability of the collective package is further enhanced.

Further, in the collective package 10 according to the present invention, it is desirable that a notch 70 for opening is formed by a perforation or the like for facilitating opening. Further, the cut portion is provided in a range Z1 from the lower end of the portion of the top surface portion 44 extending from the front surface 46 or the back surface 46 to the handle portion 45 and provided with the finger hook hole 47 to the front surface 46 and the back surface 46. Is desirable. In the top surface portion 44, the force applied to the top surface portion 44 when the finger is put on the finger hook hole 47 and lifted differs depending on the position of the finger hook hole 47. Specifically, with respect to the area extending from the lower end of the portion where the finger hook hole 47 is not provided to the front surface 26 and the back surface 26, the handle portion 45 is provided with the finger hook hole 47 from the lower end to the front surface 46. And the area Z1 extending to the back surface 46 has a smaller pulling force. Further, the top surface portion 44 is a portion that is easily noticed by the user.
Therefore, if the cut portion 70 is provided at such a position, the cut portion 70 will not be unintentionally opened when being carried, and the cut portion 70 will be easily visible. The shape of the cut portion is not particularly limited, but it is desirable that the cut portion has a shape that bulges convexly toward the handle portion side, for example, a substantially arc shape, as shown in the illustrated example. With this shape, a picking piece 70A is formed by pushing in the notch 70 and dehiscence the perforation or the like, and when pulled toward the bottom surface, as shown in FIG. 8, the gusset packaging bag is applied to the front or back surface. An opening is easily formed. The cut tie ratio at the perforation may be appropriately designed.

As the gusset packaging film 14, polypropylene film and polyethylene film are preferable from the viewpoint 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. Suitable. In addition, polyethylene terephthalate film, nylon film, vinylidene chloride film, single-layer film of ethylene vinyl alcohol copolymer, laminated film containing those films, and surface treatment such as aluminum vapor deposition on those films. 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 desirable to use a biomass film for the gusset packaging film from the viewpoint of environmental protection.
The thickness of the gusset wrapping film 14 constituting the gusset wrapping bag 13 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 particularly the film packaging tissue 1 to be included. Film packaging that is included in addition to the circumstances peculiar to gusset packaging, such as wear resistance to the square part 4t on the end face, flexibility that does not put an excessive load on the finger when carrying it through the finger hook hole provided in the handle part, etc. It is appropriately selected in consideration of the relationship with the tissue 1.

From this point of view, the thickness and softness of the gusset packaging film 14 are such that the thickness measured according to JIS P 8118 (1998) is 10 to 65 μm, and the handle ohm according to JIS L 1096 (2010) E method. The softness measured according to the method is 5.0 to 50.0 cN.

In particular, it is desirable that the softness of the gusset packaging film 14 constituting the gusset packaging bag 13 is lower than the softness of the packaging film 4 constituting the film packaging tissue 1. The gusset packaging bag 13 having the handle portion on the top surface side is a film packaging tissue that is included in the gusset packaging bag 13 because the gusset packaging bag 13 is pulled toward the top when the handle portion 45 is held. Pressure may be applied to 1, 1 ..., but by lowering the softness of the gusset packaging film 14, the straight hexahedron shape of the included film packaging tissue 1 becomes difficult to deform, and the internal bundle 3 can be pressed. It is difficult to reduce the fluffy feeling, and it is also difficult to deteriorate the take-out property such as pop-up property.

As the arrangement form of the film packaging tissue 1 in the gusset packaging bag 14, a plurality of

film packaging tissue

1, 1 ... Are arranged so that the end surface 4A and the long side surface 4B are substantially flush with each other as shown in the figure. It is desirable that they are arranged so as to be a substantially straight hexahedron as a whole. When arranged in a substantially straight hexahedron in this way, the stability and shape retention of the entire aggregate are enhanced, and it becomes difficult for the aggregate to collapse or collapse due to an external force. Further, when arranged in this way, the aggregate of the film packaging tissue 1 has a straight hexahedron shape in which a highly rigid end surface aggregate surface is formed on the top surface, so that the film is formed by an external force particularly from the top surface direction. The risk that the packaging tissue 1 is crushed or the film packaging tissue 1 is damaged is reduced. However, the arrangement of the film packaging tissue 1 in the film packaging tissue collective package 10 according to the present invention is not limited to this form.

Here, as described above, the gusset packaging bag 13 having the handle portion 45 on the top surface side is included in the gusset packaging bag 13 because the gusset packaging bag 13 is pulled toward the top bottom when the handle portion 45 is held. The package and the gusset packaging film 14 may rub against each other. In the gusset packaging bag 13, when the ridge line 14E between the gusset portion 43 and the front surface 46 and the ridge line 14E between the gusset portion 43 and the back surface 46, which are the creases 14E at the time of the gusset tube which is the precursor of the packaging bag, are fragile. There is. As shown in FIG. 9, in particular, the gusset tube 40 is formed by forming one sheet into a tubular shape and adhering the end edges to form a tube shape, and one of the fold lines 14E is an adhesive edge portion 49. In the gusset packaging bag 13 derived from the gusset tube configured in this way, the crease 14E related to the adhesive edge portion 49 is particularly liable to tear. Further, particularly in the gusset packaging having the handle portion 45 on the nadir side, since some voids are formed on the nadir side, the packaged object is restrained in the nadir direction as compared with the direction orthogonal to the nadir direction. Tends to be weak. On the other hand, in the overlap packaging, the rigidity of the end surface 4A formed by the cylinder opening sealing portion, particularly the square portion 4t, is high and tends to be sharp.

Therefore, in a film packaging tissue that is used as a stationary type that has a heavier weight than a portable film packaging tissue, for example, as shown in FIG. 11 as a comparative form, the cylinder opening of the overlap packaging is sealed. Assuming that the film packaging tissue 101A having the end face 104A is stacked and arranged so that the end surface 104 faces in the direction orthogonal to the top bottom direction as in the conventional box product, a large number of end surfaces 104A The square portion 104t of the above is in a position where it rubs against the gusset packaging bag, and when carrying with the handle portion 145, the space 110Z film packaging tissue 101A on the top surface side is not sufficiently restrained and moves inside the gusset packaging bag 113, and the film packaging tissue 101A The square portion 104t of a large number of end faces 104A rubs against the gusset packaging bag 113, and in particular, the fragile portion of the ridge line 114Z between the gusset portion 43 and the front surface and the ridge line 114E and the vicinity 114Z between the gusset portion and the back surface It may be torn (the torn part in FIG. 9 is indicated by reference numeral 200). In particular, as in the comparative form, the object to be packaged has a straight hexahedron shape, and the four edges along the nadir direction of the gusset packaging bag 113, that is, the ridge line 114E between the gusset portion and the front surface and the ridge line 114E between the gusset portion and the back surface. And, if the square portion 104t of the end surface 104A is likely to match, the risk of damage becomes remarkable. Such breakage does not occur with lightweight portable film packaging tissue, but is prominently likely with heavy film packaging tissue used as a stationary type.

In the collective package according to the present invention, the

film packaging tips

1, 1 ... Are directed toward the top surface side where each end surface 4A has the handle portion 45 and the bottom surface side facing the top surface side, and the longitudinal direction is the nadir direction. Since it is packaged according to the above, such a risk is small at each stage. In order to further reduce such a risk, it is desirable that the number and the assembly form of the film packaging tissue 1 in the gusset packaging bag 13 are two or less in the nadir direction. If the number of steps exceeds two in the nadir direction, the shape maintainability of the collective package deteriorates. Specifically, in the collective package 10 according to the present invention, since the longitudinal direction of the film packaging tissue 1 is the direction along the top-bottom direction, the uprightness in the top-bottom direction becomes high when the number of steps exceeds two and three or more. It becomes worse, and the gap between the stages is likely to occur, and the gusset packaging film 14 and the film packaging tissue 1 are likely to be rubbed. In addition, since the number of easy contact points between the square portion 4t of the end surface 4A of the film packaging tissue 1 and the gusset packaging film 14 increases, the risk of damage to the gusset packaging film 14 increases. However, if at least the same number is packaged, the arrangement form according to the present invention is superior to stacking so that the end faces 4A face in the direction orthogonal to the nadir direction as in the reference form.

The number of arrangements of the film packaging tissue 1 in the direction orthogonal to the nadir direction is not particularly limited, but it is desirable that the number of arrangements is six or less. As an example of a suitable form, as shown in FIG. 1, a total of five or six arrangement forms of one step in the direction of the top, five rows in the direction orthogonal to the top, or six rows (not shown), or As shown in FIG. 2, a total of ten or twelve rows of two rows in the direction of the top, five rows in the direction orthogonal to the top, or six rows (not shown), and a top (not shown). A total of ten or twelve rows are preferable, with one row in the direction, five or six rows in the direction orthogonal to the top and bottom, and two rows in the front-back direction. These arrangement forms are excellent in maintainability and standing stability of the straight hexahedron shape, are also excellent in portability and stackability in stores, and can be a sufficient number of products for general purchase frequency. ..

Further, in the film packaging tissue assembly package 10 according to the present invention, it is desirable that the bundle filling rate of the film packaging tissue 1 is 100% or more. Here, the bundle filling rate is the ratio of the height of the bundle 3 taken out from the packaging film 4 to the height of the film packaging tissue 1. The specific measurement method is as follows: First, the film packaging tissue 1 is humidity-controlled for 24 hours in an environment of standard conditions of 23 ° C. ± 1 ° C. and humidity of 50 ± 2% rhh based on JIS P 8111, and then placed on a horizontal table. The height of the film packaging tissue 1 is measured by placing it on top with the upper surface facing upward. The measured value is an average value of the distance L1 between the sharp portions of the square portion 4t of the end surface 4A measured at four points. Next, the bundle 3 is taken out from the film packaging tissue 1, and the humidity is adjusted for 24 hours in an environment of standard condition 23 ° C. ± 1 ° C. and humidity 50 ± 2% rhh based on JIS P 8111, and then placed on a horizontal table. The height of the bundle 3 is measured by placing it on top with the upper surface facing upward. The measured value is an average value of the distances between the square portions of the short side surface 3A facing the end surface 4A measured at four points. Next, from each measured value, the ratio of the height of the bundle 3 taken out from the packaging film 4 to the height of the film packaging tissue 1 is calculated.

In such a film packaging tissue 1 having a bundle filling rate of more than 100%, the bundle 3 pushes the packaging film 4 from the inside. In the overlap packaging, the rigidity of the end surface 4A is high and it is difficult to stretch or deform, while the portion of the packaging film 4 facing the upper and lower surfaces and the longitudinal side surface of the bundle 3 is flexible. The position and the longitudinal edge 1E are deformed so as to slightly bulge. Then, the film packaging tissue 1 with the longitudinal edge 1E bulging in this way is directed toward the top surface side where the handle portion 45 is located and the bottom surface side facing the top surface side, so that the longitudinal direction is along the top surface direction. When the gusset packaging bag is pulled toward the top with the handle portion 45, the square portion 4t of the end surface 4A hits the gusset packaging film 14 constituting the gusset packaging bag 13 due to the bulging of the longitudinal edge 1E. It becomes difficult and the possibility that the gusset packaging bag 13 is broken is reduced.

Further, in the film packaging tissue assembly package 10 according to the present invention, it is desirable that the compression ratio in the direction orthogonal to the nadir direction of the film packaging tissue assembly arranged in the gusset packaging bag is 80% or more. .. Here, the compression ratio in the direction orthogonal to the top-bottom direction refers to the case where the gusset portion 43 of the gusset packaging bag 14 is packaged so as to face the upper and lower surfaces 3C of the film packaging tissue 1 (film packaging tissue). It is (distance between the gusset portions of the gusset packaging bag (width of the front or back surface)) L2 with respect to (the length in the direction orthogonal to the top-bottom direction when the aggregate is not packaged). The length of the film-wrapped tissue shoe assembly in the direction orthogonal to the nadir direction when not wrapped is (height in the upper and lower surfaces of one of the film-wrapped tissue shoes) × (number of arrangements in the direction orthogonal to the nadir direction). calculate. The height of one film packaging tissue in the upper and lower surfaces direction is different from the height in the bundle filling rate, and is measured as follows.
First, each film packaging tissue 1 is taken out from the film packaging tissue assembly package 10, and humidity control is performed for 24 hours under an environment of standard conditions of 23 ° C. ± 1 ° C. and humidity of 50 ± 2% rhh based on JIS P 8111. To do. Next, the film packaging tissue 1 is placed on a horizontal table, and a hard acrylic having a size protruding from each edge (short side edge and long side edge) of the upper surface of the bundle on the upper surface of the bundle 3 within a range of 5 cm or less. Place the board. If the size of the upper surface of the bundle is 160 to 200 mm in the longitudinal direction (width) x 90 to 110 mm in depth, the size of the acrylic plate may be 250 mm x 130 mm. The mass shall be 32 g or less. Next, the height of the acrylic plate from the square horizontal table is measured and the average value is calculated. This measurement is performed on all film packaging tissues taken out. The further average value of the calculated average value is taken as the height in the upper and lower surface directions of one of the film packaging tissuees 1. The value obtained by multiplying this calculated value by the number of sequences is defined as "the length in the direction orthogonal to the nadir direction when the film packaging assembly is not packaged". Next, the distance between the gusset portions 43 of the gusset packaging bag 13 is measured. The measurement shall be an average value obtained by measuring the width of the front surface 46 (between the front creases) and the width of the back surface 46 (between the back creases) at three locations. Next, the ratio of the distance (front or back width) between the gusset portions of the gusset packaging bag 13 to the length in the direction orthogonal to the nadir direction when the film packaging assembly is not packaged is calculated.

If the compression ratio in the direction orthogonal to the nadir direction of the film packaging tissue assembly arranged in the gusset packaging bag 13 exceeds 90%, the compression ratio is too high, and the distortion of the end surface 4A and the tissue paper 2 The fluffy feeling tends to decrease. The upper limit of the compression ratio is not particularly limited in the packaging form of the present invention. The film packaging tissue should not move excessively within the gusset packaging bag. It does not necessarily have to be 100% or less. However, if it is 100% or less, the movement of the aggregate of the film packaging tissue is restricted by the exterior film constituting the gusset packaging bag, the exterior film is less likely to break, and the aggregate package collapses. It is more desirable that the value is 100% or less because the shape retention of the straight hexahedron is increased.

On the other hand, the individual tissue papers 2 constituting the bundle 3 packaged in the film packaging tissue 1 have a ply structure in which two to three thin paper sheets having crepes are laminated and assembled. This tissue paper 2 is a dry type, not a so-called wet type impregnated with a chemical solution. Therefore, the bundle 3 formed by the tissue paper 2 contains a large amount of air. The dry type tissue paper 2 also includes a chemical solution-imparting type in which a chemical solution such as a moisturizing component that increases water content by absorbing moisture such as a polyol represented by glycerin is added, but such a tissue paper is included. .. Rather, such a chemical solution-imparted type tissue paper has a weak resilience when compressed due to its high water content, so that the action and effect of the present invention with less decrease in fluffiness can be more effectively exhibited. The water content of the chemical solution-added type is approximately 10 to 14% by mass. Moisture content is the percentage of water contained in tissue paper under standard conditions.

The raw material pulp for thin paper that constitutes Tish Paper 2 is a mixture of NBKP and LBKP. Waste paper pulp may be blended, but it is preferable that it is composed of only NBKP and LBKP in terms of texture and the like. The blending ratio is preferably NBKP: LBKP = 20: 80 to 80:20, and particularly preferably NBKP: LBKP = 30: 70 to 60:40.

The basis weight per thin paper sheet constituting each ply of the tissue paper 2 is 10 to 25 g / m ² . Preferably, it is 12-18 g / m ² . The basis weight here refers to the measurement method of JIS P 8124 (1998). The thickness of the tissue paper 2 is 90 to 200 μm, more 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, the value measured in the state of multiple plies.

In the case of the above-mentioned tissue paper having a basis weight and a paper thickness, the fluffy feeling is not reduced and the effect is fully exhibited especially when the collective package having a low compression ratio according to the present invention is used. The nadir direction and the vertical direction in the present invention and the present specification are appropriately changed depending on the orientation of the film packaging tissue collective package and the film packaging tissue, and do not mean an absolute direction. ..
