The packaged tissue assembly package is formed by packaging a plurality of packaged tissues arranged in a gusset package having a handle portion on the top surface side, wherein the packaged tissues are stacked packages, and have end surfaces formed by a tube opening seal portion at both ends in the longitudinal direction, and the stacked packaged tissues are packaged so that the end surfaces face the top surface side where the handle portion is present and the bottom surface side opposite to the top surface side, and the longitudinal direction is along the top-bottom direction.

Description

Film-packaged tissue collection package

Technical Field

The present invention relates to a film-wrapped tissue assembly package in which a plurality of film-wrapped tissues are collectively corner-wrapped, and the film-wrapped tissues are obtained by wrapping a bundle of tissues formed by folding and stacking tissues with a soft wrapping film.

Background

A tissue package (hereinafter, also referred to as a box product) is known, which is also referred to as a box tissue and includes a bundle of tissues in a paper storage box called a carton.

Since the paper storage box as the outer case of the box product 101B has excellent shape stability, it is generally arranged so that five or three are stacked in the top-bottom direction as shown in fig. 12, and then it becomes a product form 110B of a collective package (also referred to as a package box package) which is gathered by an outer film 111, and it is often stacked in a large amount in a shop floor of a sales shop or the like and sold.

On the other hand, as a tissue package, a tissue package also called a film-wrapped tissue is known in which a bundle of tissues is wrapped with a soft wrapping film made of a resin. As this film-wrapped tissue, a film-wrapped tissue suitable for carrying, called a pocket tissue, is known, but as with a packaged product, there are also film-wrapped tissues not suitable for carrying, which are used in a fixed state or as a replacement for a bundle of packaged products.

Film-wrapped tissues used fixedly or the like in the case of a box product have advantages such as transportation cost and portability due to reduction and compactness of a wrapping material, as compared with the case of a box product. However, since such a film-wrapped tissue is wrapped with a soft wrapping film in a bundle of soft tissues, it has a poor shape-retaining property as compared with a box product, and there is a problem that a plurality of tissues are merely stacked and collectively wrapped with a film in the same manner as a box product, and a shape-retaining property suitable for stacking in a store is not obtained.

In view of such a problem, the technique disclosed in patent document 1 mentioned below is adapted to store in storefront as a box-like product as a whole by forming a suction/discharge hole in a film-wrapped napkin to compress the film-wrapped napkin, and then restraining the paper with an assembly wrap film in a compressed state and performing assembly wrapping with a gusset wrap.

Problems to be solved by the invention

However, if such a compressed state is maintained for a long time, the bulky feel of the sheet may be reduced. In particular, the possibility of a bulky feeling being reduced is further increased in a tissue having a high water content such as a moist tissue containing a chemical solution or in a high-humidity environment.

On the other hand, in the collective package of the film-wrapped tissues, it is preferable to be suitable for a gusset package of a flexible packaged article such as a roll toilet paper. In addition, a collective package of film-wrapped tissues, which is mainly used for carrying and the like, is not as large as a normal bag, and is preferably a gusset package with a handle portion because it has a certain weight.

However, in this gusset package, since a space is easily formed particularly on the top surface side and the bottom surface side in terms of structure, if the compressibility of the film-wrapped paper towel is reduced to simply reduce the constraint, the film-wrapped paper towel enclosed therein is easily moved. Since the sealed portion of the film-wrapped napkin formed by heat-sealing or the like of the wrapping film is hard, if the wrapped film-wrapped napkin is easily moved, the hard portion is more likely to be broken by rubbing against the outer film constituting the gusset package.

Therefore, a main object of the present invention is to provide a film-wrapped tissue assembly package in which tissues are wrapped with a film, which is used in a fixed manner such as a box product, and which has excellent shape retention properties such as ease of store-side stacking and sales without reducing the bulky feeling of the wrapped tissues, and in which the assembly package film is not easily damaged. Further, a packaged tissue assembly package is provided which is excellent in the taking-out property of the wrapped tissue and also excellent in the unsealing property and the transportability of the assembly package.

Detailed Description

The present invention will be described below with reference to fig. 1 to 10 as an embodiment and fig. 11 as a comparative embodiment.

The film-wrapped napkin collective package 10 (hereinafter, also referred to as a collective package) of the present invention is formed by arranging a plurality of film-wrapped napkins 1, and wrapping the plurality of film-wrapped napkins 1 in a gusset package bag 13 having a grip portion 45 on the top surface side, and then performing gusset packaging, wherein the film-wrapped napkins 1 are formed by wrapping a bundle 3 formed by folding and superposing a plurality of tissues 2 on each other with a flexible packaging film 4.

The film-wrapped paper towel 1 of the present invention is formed by stacking and wrapping a bundle of paper 3. The laminated packaging is a packaging method also called caramel packaging or inclusion packaging, and as shown in fig. 3 to 5, a packaging method is a packaging method in which a sheet bundle 3 as a packaged object is wrapped in a roll shape by a packaging film 4 so as to form openings 4Z at both ends in the longitudinal direction, a portion 4X overlapped in the wrapping direction is bonded by a welding treatment or an adhesive, a portion 4Y extending over the sheet bundle 3 is folded from the vicinity of both opposite edges of the sheet bundle end face to the end face side of the sheet bundle 3, at least each end edge portion of the substantially triangular or substantially trapezoidal sheet formed at this time is overlapped with each other and bonded by a welding treatment or an adhesive, and the opening 4Z of the roll is sealed to form an end face 4A.

In this laminated package, the end face 4A has a substantially planar shape, and therefore has a substantially rectangular parallelepiped shape close to a box shape on the basis of the outer package of the packaging film 4. The end face 4A is formed by stacking and then bonding the plurality of packaging films 4, and therefore has high rigidity, is difficult to crush, and easily maintains a substantially regular hexahedral shape.

Therefore, when the film-wrapped paper towel 1 is a stacked package, the product shape is substantially a regular hexahedron, and therefore, as shown in fig. 1 and 2, even when collectively packaged in an aligned manner, the entire product can be formed into a regular hexahedron shape. Therefore, the collective packages can be easily stacked in a plurality of layers in order, and can be easily stacked in a storefront for sale. Even if stacked in this manner, since the outer package of the packaging film 4 has high rigidity, it is difficult to apply a compressive force to the sheet bundle 3 inside, and the bulky feeling of the napkin 2 is not easily reduced.

The bundle 3 of paper towels enclosed in the film-wrapped paper towel 1 is preferably pop-up. In particular, as shown in fig. 7, the pop-up sheet bundle 3 is formed by folding a substantially rectangular napkin 2 having a longitudinal direction of 197 ± 10mm × a lateral direction of 217 ± 10mm in two, positioning the folded piece 2B of the other napkin 2 positioned at the upper and lower positions on the inner side 2A after the folding, and folding and stacking a plurality of napkins 2, and when the uppermost folded piece is pulled up, the other folded piece 2B adjacent to the uppermost folded piece is pulled up and lifted. Such a bundle 3 can be manufactured by a multi-stand, rotary type known interfolder. The paper bundle 3 according to the present invention may be a non-pop-up paper bundle having a substantially rectangular parallelepiped shape formed by folding and stacking a plurality of sets of paper towels 2.

The pop-up sheet bundle 3 includes: a pair of long side surfaces 3B formed by arranging the folded edges 2C of the tissues 2; and a pair of short side surfaces 3A where the folded edges 2C are not arranged, and a pair of flat surfaces (upper and lower surfaces) 3C connected to the short side surfaces 3A and the long side surfaces 3B, and having a substantially rectangular parallelepiped shape. Further, since the tissue 2 is made of soft tissue, it is soft and easily compressed and deformed.

The number of sets of the sheets 2 constituting the bundle 3 is not limited, and generally, two sheets (2 sheets stacked) or 3 sheets (3 sheets stacked) are set as 1 set, and 120 to 240 sets. The size of the sheet bundle 3 is not necessarily limited, but the two-ply sheets are 150 sets and the bundle is approximately 40mm to 50mm in height, 160mm to 200mm in the longitudinal direction (width), and 90mm to 110mm in the short direction (depth). As shown in this shape, the film-wrapped napkin 1 of the present invention is not a portable napkin having about ten to twelve napkin groups and a height of about 10mm, which is included in a so-called pocket napkin or the like.

In the film-wrapped paper towel 1 of the illustrated embodiment, the end face 4A formed by sealing the tube opening 4Z is positioned to face the short side face 3A of the bundle 3, and an opening perforation line 5 is formed at a position to face the uppermost paper towel 2 of the bundle 3 of the wrapping film 4. In particular, the film-wrapped paper towel 1 of the illustrated embodiment is formed by folding a paper towel 2 in two, stacking and wrapping a bundle 3 of paper towels 2 in a pop-up substantially rectangular parallelepiped shape in which a plurality of paper towels 2 are stacked and folded such that a folded-back piece 2B of another paper towel 2 positioned at the upper and lower positions is positioned on the inside 2A after the folding-back, and has a paper towel take-out opening forming portion 5 on the upper surface, and an end surface 4A as a sealing portion of a tube opening 4X is positioned at a position facing a short side surface 3A where folded-back edges 2C of the bundle 3 are not arranged.

When the sheet bundle 3 is pop-up as in the illustrated embodiment and the uppermost sheet 2 of the sheet bundle 3 is pulled out by forming the open seal, a part of the next sheet located immediately below the uppermost sheet is exposed from the open seal. In the film-wrapped paper towel 1 configured as described above, since the paper towel is stacked in the direction in which the end face 4A having high rigidity stands, the paper bundle 3 is less likely to be compressed even if a compressive force is applied in the stacking direction (vertical direction), and the bulky feeling is less likely to be reduced.

In addition, the film-wrapped paper towel 1 may be formed with air intake and exhaust holes communicating with the inside and outside in order to prevent breakage or the like when external pressure is applied. The suction/discharge hole may be provided in the end face 4A of the packaging film 4 facing the short-side face 3A where the folded edges 2C of the sheet bundle 3 are not arranged, but preferably, no suction/discharge hole is provided in this position. If the air suction/discharge hole is provided in the end face 4A, the weakness of the end face 4A is improved, and therefore the advantage of the laminated package having the end face 4A with high rigidity is reduced.

As shown in fig. 3, the outlet forming portion 5 may be a straight perforation line 5 for unsealing extending in the longitudinal direction at the center in the lateral direction, but as shown in fig. 4, a perforation line may be formed in an elongated loop shape extending in the longitudinal direction to form an elongated opening. Although not shown, the opening perforation line 5 may be covered with a peelable seal.

In particular, as shown in fig. 5, the preferred shape of the outlet forming portion 5 is preferably a shape having an opening 50 formed in the center in the short side direction, and the opening 50 has a slit portion 51 extending in the long side direction and a widened portion 52 communicating with an end of the slit portion 51 and gradually widening as it goes away from the slit portion 51 in the long side direction. The opening 50 preferably has a shape having a curved portion 53 continuous with the widened portion 52 and bulging convexly toward the longitudinal end. In this case, the length L3 of the portion where the ejection opening forming portion 5 is present may be shorter than the length L4 of the sheet bundle 3 in the longitudinal direction, and may be approximately 60% to 80% of the length L4 of the sheet bundle 3 in the longitudinal direction.

The width (length in the short side direction) of the slit portion 51 is 10mm or less, preferably 7mm or less in the short side direction. As shown in fig. 5(B), the width that can open the straight perforation line may not be substantially provided.

When the ejection opening is formed in the shape of the ejection opening forming portion 5, the edge portion 51A of the slit portion 51 becomes a free edge piece which is easily movable in the vertical direction, and therefore, when a set of sheets is ejected from the sheet bundle, the edge piece is deformed in the ejection direction and is supported by the backrest of the next exposed set of sheets. Further, the next sheet, a part of which is exposed from the take-out opening after the sheet drawn out from the sheet bundle, is easily deformed into a shape with high standing property because the edge in the longitudinal direction is curled along the edge of the curved portion. In the opening perforation line shown in the figure, it is difficult for tissues, which are likely to occur in a laminated package having a regular hexahedral shape, to fall into the internal space.

The ratio of the cut and connection of the perforation lines forming the outlet forming portion 5 can be determined appropriately according to the ease of breaking of the film to be used, and a preferable example is a cut portion having a length of 0.8mm to 5.0mm, and a connection portion having a length of 0.3mm to 5.0 mm. The ejection opening forming portion 5 shown in fig. 5 is not formed by all perforation lines, but may be formed by a slit portion and a widened portion formed by perforation lines, and a part of the bent portion (in the illustrated example, the longitudinal end) may be formed by a slit cut portion provided with an anchor portion. The outlet is easily opened by the curved portion.

Specific examples of the flexible resin-made packaging film 4 constituting the outer package of the film-packaged paper towel 1 include a polyethylene film, a polypropylene film, a polyester film, a polyethylene terephthalate film, a nylon film, a polyvinylidene chloride film, a single-layer film of an ethylene-vinyl alcohol copolymer, a laminated film comprising an appropriate laminate of these films, and a gas barrier film obtained by subjecting these films to surface treatment such as aluminum deposition. In addition, biomass membranes derived from plant materials such as sugarcane, potato (starch), and corn can also be used. The use of such a biomass membrane is preferable from the viewpoint of environmental protection.

From the viewpoint of cost, a polypropylene film and a polyethylene film are preferable. The packaging film 4 may be a pear coating film having excellent design and texture. Further, when packaging a scented tissue or the like having a scent, an ethylene-vinyl alcohol copolymer resin film or a polyethylene terephthalate resin film having excellent scent retention is preferable. The heat-sealing resin film may be a multilayer resin film in which a polyethylene resin film or a polypropylene resin film is laminated on one surface or both surfaces of an ethylene-vinyl alcohol copolymer resin film or a polyethylene terephthalate resin film to improve heat-sealing properties.

The thickness of the packaging film 4 may be appropriately selected in consideration of flexibility, cost, air permeability, and heat-sealing property at the time of packaging, but it is preferable that the thickness be 25 μm to 75 μm as measured according to JIS P8118 (1998) and the softness be 5.0cN to 50.0cN as measured by a manual method according to JIS L1096 (2010) E. When the thickness is 25 μm to 75 μm, the rigidity of the end face 4A is sufficiently improved. Further, if the thickness and softness are concerned, the packaging film 4 is not easily broken, and the taking-out property of the napkin, particularly the pop-up property, is easily improved. The thickness was measured using a dial (thickness measuring instrument) "PEACOCK G-1A type" (manufactured by Kawasaki corporation) and a corresponding device thereof after the humidity of the measurement sample was sufficiently adjusted under JIS P8111 (1998).

In the film-wrapped napkin collective package 10 according to the present invention, a plurality of film-wrapped napkins 1 stacked and wrapped are gusset-wrapped in a gusset wrapping bag 13 such that the longitudinal direction thereof is along the top-bottom direction, with the end face 4A facing the top surface side of the grip portion and the bottom surface side facing the top surface side.

The gusset package is a package in which an object to be packed is packed in a bag-like space between

adhesive parts

41 and 42 located on the top and bottom sides and formed by thermal fusion bonding or the like, and particularly, has a gusset portion (japanese マチ portion) 43, 43 between the front and back sides. As shown in fig. 8 and 9, the gusset package is manufactured, for example, as follows: the

side portions

40E, 40E of the cylindrical gusset packaging film 14 called a gusset tube 40 are folded into the bag interior, the portions of the flat gusset tube on the top surface side are heat-welded, the opening on the top surface side is sealed as a top surface side sealing portion 41, and a handle portion 45 is formed, then the bottom surface side opening 40X of the gusset packaging bag precursor sealed only on the top surface side is expanded, and the object to be packaged (in the illustrated embodiment, the film-packaged

tissues

1, 1 …) is inserted therefrom, and then the bottom surface side is also sealed by an appropriate sealing means such as heat welding, to form a lower sealing portion 42. In the gusset package, a gusset package bag 13 serving as an exterior package includes: spreading

parts

43, 43 formed by opening the

side parts

40E, 40E folded in a flat state; and each surface connected to the expanding portion 43. The two surfaces connected to the

respective struts

43, 43 are the front surface 46 and the back surface 46, but the front surface 46 and the back surface 46 are opposed to each other, and it is not limited which surface is the front surface.

In order to improve the transportability of the assembled package, the handle portion 45 is provided in a remaining portion on the top surface side of the top surface side sealing portion 41 which is a boundary on the top surface side of the pocket portion in the film-wrapped napkin 1. In the illustrated embodiment, a finger hole 47 is formed. In this way, when the finger hole 47 is formed in the grip portion 45, the transportability of the assembled package is further improved.

In the collective packaging body 10 of the present invention, it is preferable that a notch 70 for opening is formed by a perforation line or the like for facilitating opening. The cut is preferably provided in a range Z1 from the front surface 46 or the rear surface 46 to the top surface 44 of the grip portion 45, that is, from the lower end of the portion where the finger hole 47 is provided to the front surface 46 and the rear surface 46. In the top surface portion 44, when a finger is hooked to the finger hook hole 47 and lifted, a force applied to the top surface portion 44 differs depending on the position of the finger hook hole 47. Specifically, the region Z1 extending from the lower end of the portion of the handle portion 45 where the finger hole 47 is provided to the front surface 46 and the rear surface 46 is less tensioned than the region extending from the lower end of the portion where the finger hole 47 is not provided to the front surface 26 and the rear surface 26. In addition, the top face portion 44 is a portion that is easily visible to the eyes of the user.

Therefore, if the cut portion 70 is provided at such a position, the cut portion 70 is not opened accidentally during transportation, and the cut portion 70 is easily visually recognized. The shape of the cut portion is not particularly limited, but as shown in the drawing, it is preferably a shape bulging convexly toward the grip portion side, for example, a substantially circular arc shape. With this shape, the cut 70 is pressed in to break the perforation line or the like to form the tab 70A, and thus, when the tab 70A is pulled in the direction of the bottom surface, as shown in fig. 8, the opening seal up to the front surface or the back surface of the gusset package bag can be easily formed. The cutting connection ratio of the perforation lines can be designed appropriately.

The gusset packaging film 14 is preferably a polypropylene film or a polyethylene film in view of cost and opening property. The melting point of the film is preferably 150 ℃ or lower. Further, the heat-sealing treatment can be performed at a low temperature when the melting point of the wrapping film is low, and is preferable for forming the seal or the grip, but when the melting point is too low, damage or a possibility of occurrence of a hole is increased due to friction or the like with the four corner portions 4t of the end face 4A of the film-wrapped napkin 1, and therefore, the lower limit value is substantially 80 ℃. 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, from the viewpoint of heat-weldability and cost, it is particularly suitable that the density is 0.910g/cm³～0.940g/cm³And a linear low density polyethylene film layer (LLDPE) having a melting point of 110 ℃ to 120 ℃. Further, a polyethylene terephthalate film, a nylon film, a polyvinylidene chloride film, a single-layer film of an ethylene-vinyl alcohol copolymer, a laminated film including an appropriate laminate of these films, and a gas barrier film obtained by subjecting these films to a surface treatment such as aluminum deposition may be used. Bag withSimilarly, a biomass membrane derived from a plant material such as sugarcane, potato (starch), or corn may be used as the envelope 4. From the viewpoint of environmental protection, it is preferable to use a biomass film in the gusset packaging film.

The thickness of the gusset packaging film 14 constituting the gusset packaging bag 13 is appropriately selected in consideration of the relation with the film-packaged paper towel 1 to be wrapped, which is unique to the gusset packaging, in addition to the case where flexibility, cost, heat-sealing property at the time of packaging, tearability at the time of unsealing which can be easily unsealed, abrasion resistance of the film-packaged paper towel 1 to be wrapped, particularly, to the end face four corners 4t, and flexibility which does not apply excessive load to the finger when the finger passes through the finger hook hole provided in the handle portion are taken into consideration.

From such a viewpoint, the thickness and softness of the gusset packaging film 14 are preferably 10 μm to 65 μm as measured by JIS P8118 (1998) and 5.0cN to 50.0cN as measured by a manual measurement method according to JIS L1096 (2010) E.

In particular, the softness of the gusset packaging film 14 constituting the gusset packaging bag 13 is preferably lower than the softness of the packaging film 4 constituting the film-packaged napkin 1. When the gusset packaging bag 13 having the grip portion on the top surface side has the grip portion 45, the gusset packaging bag 13 is pulled in the top-bottom direction, and therefore, pressure may be applied to the film-packaged

tissues

1 and 1 … as the objects to be packaged contained at this time, but by reducing the softness of the gusset packaging film 14, the regular hexahedral shape of the film-packaged tissues 1 contained therein is hardly deformed, the pile 3 inside is hardly pressed, the feeling of bulkiness is reduced, and the taking-out property such as the pop-up property is hardly deteriorated.

As a mode of arranging the film-wrapped napkin 1 in the gusset packaging bag 14, as shown in the figure, it is preferable that the plurality of film-wrapped

napkins

1 and 1 … are arranged in a substantially regular hexahedron as a whole so that the end face 4A and the long-side face 4B are substantially flush with each other. In this way, when arranged in a substantially regular hexahedron, the stability and shape retention of the entire assembly are improved, and deformation or crushing due to external force is less likely to occur. Further, since the assembly of the film-wrapped tissues 1 has a regular hexahedral shape with a highly rigid end-face assembly face formed on the top and bottom faces, the film-wrapped tissues 1 are less likely to be deformed or the film-wrapped tissues 1 are less likely to be damaged by an external force applied particularly from the top and bottom directions. However, the arrangement of the film-wrapped tissues 1 in the film-wrapped tissue assembly package 10 of the present invention is not limited to this embodiment.

Here, as described above, the gusset packaging bag 13 having the grip portion 45 on the top surface side may rub the article to be packed in the inner bag against the gusset packaging film 14 because the gusset packaging bag 13 is pulled in the top-bottom direction when the grip portion 45 is gripped. In the gusset packaging bag 13, the fold 14E at the time of gusset of the packaging bag precursor, that is, the fold 14E between the gusset portion 43 and the front face 46 and the fold 14E between the gusset portion 43 and the back face 46 may be weak. As shown in fig. 9, in particular, the gusset tube 40 is formed in a tubular shape by bonding the end edges of one sheet of material, and one fold 14E is formed as the bonding edge 49, and in the gusset package bag 13 formed of the gusset tube thus configured, the fold 14E of the bonding edge 49 is particularly likely to be torn. In addition, in particular, in the gusset package having the handle portion 45 on the top surface side, since a few gaps are formed on the top surface side, there is a tendency that the packing material is less restrained in the top-bottom direction than in the direction orthogonal to the top-bottom direction. On the other hand, in the laminated package, the end face 4A formed by the tube opening seal portion has high rigidity, particularly the four corner portions 4t, and is likely to be sharp.

Therefore, in a film-wrapped tissue used as a fixed type having a quality higher than that of a film-wrapped tissue for carrying, for example, as a comparative method, if a film-wrapped tissue 101A having an end face 104A sealing a tube opening of a stacked package is formed in a form 110A in which end faces 104 are stacked and arranged in a direction orthogonal to a top-bottom direction as in a conventional box-shaped product, as shown in fig. 11, four corners 104t of a plurality of end faces 104A are located at positions where they rub against a gusset package bag, and when the tissue 101A in a space 110Z on the top surface side is transported by a handle 145, the film-wrapped tissue 101A moves in the gusset package bag 113 without being sufficiently restrained, and the four corners 104t of the plurality of end faces 104A of the film-wrapped tissue 101A rub against the gusset package bag 113, particularly, and there are cases where a portion 114Z near a ridge 114E between a and the front surface of a stretch portion 43 and a portion are broken and a portion in a weak portion near 114Z near the ridge 114E and the back surface (a portion for a portion in fig. 9 is a portion for use as a portion for carrying As indicated by reference numeral 200). In particular, as in the comparative example, since the packaged object has a regular hexahedral shape, the square edges along the top-bottom direction of the gusset packaging bag 113, that is, the ridge line 114E between the expanded portion and the front surface, and the ridge line 114E between the expanded portion and the rear surface, and the four corners 104t of the end surface portion 104A easily match, and the possibility of breakage becomes remarkable. Such a damage is not generated in a lightweight film-wrapped tissue for carrying, but is easily generated remarkably in a film-wrapped tissue for stationary use having mass.

In the collective package of the present invention, the end faces 4A of the film-wrapped

tissues

1 and 1 … are wrapped so that the longitudinal direction thereof is along the top-bottom direction, toward the top face side having the grip portion 45 and the bottom face side opposite to the top face side, and therefore the possibility of this is small in each layer. In order to further reduce such a possibility, it is preferable that the number and the form of assembly of the film-wrapped tissues 1 in the gusset packaging bag 13 are two or less in the top-bottom direction. If the number of layers exceeds two in the top-bottom direction, the shape retention of the collective packaging body is reduced. Specifically, in the assembled package 10 of the present invention, since the longitudinal direction of the film-wrapped napkin 1 is the direction along the top-bottom direction, if the number of layers exceeds two and becomes three or more, the standing property in the top-bottom direction deteriorates, and the interlayer shift is likely to occur, and the friction between the gusset wrapping film 14 and the film-wrapped napkin 1 is likely to occur. Further, since the easy-to-contact portion between the four corners 4t of the end face 4A of the film-wrapped napkin 1 and the gusset wrapping film 14 is increased, the possibility of breakage of the gusset wrapping film 14 is increased. However, if at least the same number of packages are packed, the arrangement of the present invention is more excellent than the reference method in which the end faces 4A are stacked so as to face the direction orthogonal to the top-bottom direction.

The number of lines in the film-wrapped paper towel 1 in the direction perpendicular to the top-bottom direction is not particularly limited, but is preferably six or less. As examples of preferred modes, there may be: as shown in fig. 1, the array may be an array in which one layer is formed in the top-bottom direction and five or six rows, not shown, are formed in total in the direction orthogonal to the top-bottom direction, or as shown in fig. 2, ten or twelve rows of five or six rows, not shown, are formed in two layers in the top-bottom direction and five or six rows, not shown, are formed in the direction orthogonal to the top-bottom direction, and further not shown, but may be an array in which one layer is formed in the top-bottom direction, five or six rows are formed in the direction orthogonal to the top-bottom direction, and further ten or twelve rows are formed in the front-back direction. These arrangements are excellent in maintenance of a regular hexahedral shape, standing stability, transportability, and stacking property in storefronts, and can provide a sufficient number of commodities with respect to general purchase frequency.

Further, in the film-wrapped napkin collection package 10 of the present invention, the sheet pack filling rate of the film-wrapped napkin 1 is preferably 100% or more. Here, the pack filling ratio is a ratio of the height of the pack 3 taken out from the wrapping film 4 to the height of the film-wrapped paper towel 1. In a specific measurement method, first, the film-wrapped paper towel 1 was subjected to humidity conditioning for 24 hours in an environment of a standard state of 23 ℃ ± 1 ℃ and a humidity of 50 ± 2% r.h in accordance with JIS P8111, and then placed on a horizontal table with the upper surface facing upward, and the height of the film-wrapped paper towel 1 was measured. The measurement value is an average value of distances L1 between sharp portions of the four corners 4t of the end face 4A measured at four positions. Subsequently, the sheet bundle 3 was taken out of the film-wrapped paper napkin 1, subjected to humidity conditioning for 24 hours in an environment of 23 ℃. + -. 1 ℃ and a humidity of 50. + -. 2% r.h in a standard state based on JIS P8111, and then placed on a horizontal table with the upper surface facing upward, and the height of the sheet bundle 3 was measured. The measured value is an average value of distances between four corners of the short side face 3A opposed to the end face 4A measured at four positions. Next, from the respective measured values, the ratio of the height of the bundle 3 taken out of the wrapping film 4 to the height of the film-wrapped paper towel 1 is calculated.

In the film-wrapped paper towel 1 having a pack filling rate of more than 100%, the pack 3 presses the wrapping film 4 from the inside. In the laminated package, the end face 4A has high rigidity and is hard to stretch or deform, while the package film 4 has flexibility in the portions facing the upper and lower surfaces and the long-side faces of the sheet bundle 3, and therefore, these positions and the long edge 1E are deformed so as to slightly bulge out. Further, when the film-wrapped napkin 1 having the long edge 1E bulged as described above is collectively wrapped so that the longitudinal direction thereof is along the top-bottom direction toward the top surface side having the grip portion 45 and the bottom surface side opposed to the top surface side, when the gusset package bag is pulled in the top-bottom direction by the grip portion 45, the four corners 4t of the end surface 4A are less likely to touch the gusset package film 14 constituting the gusset package bag 13 by bulging of the long edge 1E, and the gusset package bag 13 is less likely to break.

Further, in the film-wrapped-napkin assembly package 10 of the present invention, it is preferable that the compression ratio of the film-wrapped-napkin assembly arranged in the gusset package in the direction orthogonal to the top-bottom direction is 80% or more. Here, the compression ratio in the direction orthogonal to the top-bottom direction means L2 (the distance between the stretched portions of the gusset packaging bag (the width of the front surface or the back surface)) that faces (the length in the direction orthogonal to the top-bottom direction when the assembly of the film-packaged tissues is unpacked) when the gusset packaging bag 14 is packaged so that the stretched portions 43 face the upper and lower surfaces 3C of the film-packaged tissues 1. The length of the film-wrapped tissue assembly in the direction orthogonal to the top-bottom direction when it is not wrapped is calculated as (height of the top-bottom surface direction of one film-wrapped tissue) × (number of lines in the direction orthogonal to the top-bottom direction). The height of one film-wrapped napkin in the upper and lower surface directions was different from the height of the pack filling ratio, and was measured as follows.

First, each of the film-wrapped tissues 1 was taken out from the film-wrapped tissue assembly package 10 and subjected to humidity conditioning for 24 hours in an environment of 23 ℃. + -. 1 ℃ and a humidity of 50. + -. 2% r.h in a standard state according to JIS P8111. Next, the film-wrapped paper towel 1 was placed on a horizontal table, and a hard acrylic plate having a dimension extending 5cm or less from each edge (short side edge and long side edge) of the upper surface of the paper bundle 3 was placed on the upper surface of the paper bundle. If the size of the upper surface of the sheet bundle is 160mm to 200mm in the longitudinal direction (width) and 90mm to 110mm in depth, the size of the acrylic sheet may be 250mm to 130 mm. The mass is 32g or less. Next, the height of the four corners of the acrylic plate from the horizontal stage was measured and the average value was calculated. The measurement was performed in a fully film wrapped tissue removed. A further average value of the calculated average values was taken as the height of one film-wrapped paper towel 1 in the upper and lower surface directions. The value obtained by multiplying the calculated value by the number of arrangements is defined as "the length in the direction orthogonal to the top-bottom direction when the film package aggregate is unpacked". Next, the distance between the opened portions 43 of the gusset bag 13 is measured. The measurement is an average value obtained by measuring the width of the front surface 46 (between the front surface folds) and the width of the back surface 46 (between the back surface folds) at 3 positions. Next, the ratio of the distance between the stretched portions of the gusset packaging bag 13 (the width of the front or back) to the length in the direction orthogonal to the top-bottom direction when the film packaging aggregate is unpacked is calculated.

When the compressibility of the film-wrapped tissue assembly arranged in the gusset wrapping bag 13 in the direction perpendicular to the top-bottom direction exceeds 90%, the compressibility is too high, the end face 4A is easily deformed, and the bulky feeling of the tissue 2 is easily reduced. The upper limit of the compression rate is not particularly limited in the packaging method of the present invention. So long as the film wrapped tissue does not excessively move within the gusset package. It is not necessarily required to be 100% or less. However, if the content is 100% or less, the movement of the assembly of the film-wrapped napkin is restricted by the outer film constituting the gusset packaging bag, and the outer film is less likely to break, and further, the deformation of the assembly package is small, and the shape retention of the regular hexahedron is also improved, so that 100% or less is more preferable.

On the other hand, each of the paper towels 2 constituting the bundle 3 packed with the film-packed paper towel 1 has a layer structure in which 2 to 3 sheets of thin paper having wrinkles are stacked to form a group. The paper towel 2 is a dry paper towel, not a so-called wet paper towel impregnated with a chemical solution. Therefore, the bundle 3 formed of the paper towels 2 contains a large amount of air. In addition, there are also chemical-solution-applied type tissues to which a chemical solution such as a moisturizing component that increases moisture by absorbing moisture, such as a polyhydric alcohol typified by glycerin, is applied in the dry type tissues 2, and such tissues are included. On the other hand, such a chemical-solution-applied type tissue has a low recovery property when compressed due to a high water content, and therefore, the effect of reducing the bulky feeling of the present invention can be more effectively exhibited. The water content of the chemical solution application type is approximately 10 to 14 mass%. The moisture content is a ratio of moisture contained in the napkin in a standard state.

NBKP and LBKP are blended as raw material pulp of tissue paper constituting the tissue paper sheet 2. The pulp may be mixed with waste paper pulp, but it is preferably composed of only NBKP and LBKP in terms of hand feeling and the like. The blending ratio is preferably 20: 80 to 80: 20 NBKP to LBKP, and particularly preferably 30: 70 to 60: 40 NBKP to LBKP.

The weight per unit area of each of the layers constituting the napkin 2 was 10g/m²～25g/m². Preferably 12g/m²～18g/m². The weight per unit area herein means the weight per unit area according to the measurement method of JIS P8124 (1998). The thickness of the paper towel 2 is preferably 90 to 200 μm, more preferably 90 to 140 μm in a two-ply state. And 120 to 300 μm in the state of 3 layers. The paper thickness herein is a value measured in a state of a plurality of layers under the same conditions using a dial (thickness measuring instrument) "PEACOCK G type" (manufactured by Kawasaki, Ltd.) and its corresponding devices after the test piece was sufficiently humidified under the conditions of JIS P8111 (1998).

In the case of the tissue paper having the above-mentioned weight per unit area and a paper thickness, the effect can be sufficiently exhibited without lowering the bulky feeling particularly in the case of producing the assembled package having a low compression ratio of the present invention. In the present invention and the present specification, the top-bottom direction and the vertical direction are appropriately changed depending on the orientation of the film-wrapped napkin collection package and the film-wrapped napkin, and do not mean absolute directions.
