Description

[Technical field]

[0001] The present invention relates to a lotion tissue paper package. [Background technology]

[0002] Thin paper such as tissues are usually sold in a packaged form in which multiple sheets are stacked together.

[0003] Such tissue paper sales packages include box-shaped cartons made of rigid paper, as well as soft packs made of soft paper or plastic film, which are convenient to carry.

[0004] Caramel wrapping and pillow wrapping are commonly used packaging formats for tissue paper soft packs. Caramel wrapping has a good shape (appearance) of the package and is tightly wrapped, so when opening the perforation at the opening of the package, the package can be held firmly with the hand, making it easy to open the perforation.

[0005] On the other hand, caramel packaging has a good shape, but it is difficult to package. Specifically, if the height of the tissue paper stack is not consistent to a certain extent, the heat seal during packaging is not stable. Therefore, the height of the stack differs between the top and bottom of the original roll, which often leads to defective products being produced during packaging depending on the original roll.

[0006] In addition, while the pillow packaging is easier to package than the caramel packaging, the shape of the package is inferior.

[0007] For example, Patent Document 1 discloses a sheet package for tissue paper using caramel packaging, which includes a sheet laminate in which multiple moisture retaining sheets are laminated, and a packaging bag for packaging the sheet laminate, and the sheet laminate is stored in the packaging bag in a state where it is compressed in the stacking direction at a compression rate of 50% to 80%. It also describes that the sheet laminate is caramel packaged.

[0008] On the other hand, as an example of a packaging body for tissue paper using pillow packaging, Patent Document 2 discloses a sheet packaging body having a pillow packaging bag that contains multiple stacked sheets and has a pair of sealed portions at both ends in the longitudinal direction, and an outlet formed on the top surface of the pillow packaging bag and extending in the longitudinal direction of the pillow packaging bag, wherein the pillow packaging bag has a paper layer containing a paper component and a resin layer containing a thermoplastic resin provided on at least one side of the paper layer, the ratio of the paper component being 50% or more, and when the sheet has one ply, the length of the outlet is 80% or more and 100% or less of the distance between the pair of sealed portions in the longitudinal direction of the top surface, and when the sheet has two or more plies, the length of the outlet is 70% or more and 90% or less of the distance between the pair of sealed portions in the longitudinal direction of the top surface.

[0009] [Patent Document 1] Patent Publication No. 2021-113085 [Patent Document 2] JP 2022-115638 A Summary of the Invention [Problem to be solved by the invention]

[0010] Incidentally, when a tube-type film is used as the packaging base material of a package, the shape of the package is good. Therefore, when opening the perforation at the opening, it is easy to open. However, when the tissue laminate is a soft lotion tissue, when the laminate is inserted into the tube-type film, the upper and lower parts of the laminate may come into contact with the film and turn over, resulting in a defective product. Therefore, if a film with a circumferential length larger than the circumferential length of the laminate within a certain range is used, the upper and lower parts of the laminate will not easily turn over, but the tightness of the package will be reduced.

[0011] Furthermore, in the case of tissue laminates that are soft lotion tissues, when the amount of lotion tissues contained in the package is reduced, a space is created inside the package to the extent that the lotion tissue paper protruding from the dispensing opening may fall back into the package, making the package unsuitable for use.

[0012] As described above, in the conventional package in which lotion paper tissues are wrapped in a tube-type film, the package has good tightness, the lotion paper tissues are unlikely to drop back during use, and the package needs to be replaced less frequently. Furthermore, when wrapping the lotion tissue laminate (inserting it into the tube-type film), it is difficult to make the top and bottom of the laminate not easily turn up.

[0013] The present invention has been made in view of the above circumstances, and has an object to provide a lotion tissue paper package in which lotion tissue paper having a pleasant feel is gusset-packaged with a tube-type film, which has good tightness, the lotion tissue paper is unlikely to drop back, requires less frequent replacement, and the lotion tissue paper is unlikely to turn over during packaging.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] Hereinafter, the form for carrying out the present invention (hereinafter, the embodiment) will be described in detail with reference to the drawings. However, these are presented for the purpose of illustration only and are not intended to limit the present invention.

[0030] In the specification, "MD direction" and "CD direction" respectively refer to the direction of the production line (conveying direction) and the direction perpendicular to the direction of the production line during the production of the lotion tissue paper package. In addition, in the specification, "drop back" refers to the phenomenon in which, in the case of a soft lotion tissue laminate, when the lotion tissue to be packaged is reduced, a space is created in the package by the amount of the reduction, and the lotion tissue paper protruding from the outlet falls back into the package.

[0031] <Lotion tissue paper packaging> FIG. 1 is a perspective view showing an example of the lotion tissue paper package (hereinafter, also simply referred to as the "package") and lotion tissue laminate of the present invention. The package 1 of the present invention is a package base material 10 of a tube-type film having at least a layer of a matte polyethylene film as the outermost layer, which covers a lotion tissue laminate 11 (hereinafter, also simply referred to as the "laminate") in which lotion tissue paper is laminated, and the lotion tissue laminate 11 is sealed by a seal part 12. The seal part 12 is preferably provided at the end where the package base material 10 overlaps. In this case, as shown in FIG. 1, the seal part 12 is preferably formed in a substantially straight line at a position about 10 mm from both ends of the package 1, and each seal part 12 is preferably formed so that they are substantially parallel to each other, but may be formed at other positions as long as the sealability of the package 1 (adhesiveness of the seal part 12) can be ensured. The seal part 12 may be a dotted line instead of a straight line.

[0032] As shown in Fig. 2, the package 1 preferably has an opening 15 for taking out the lotion paper tissues 21. The opening 15 may be provided at any location so long as it is easy to take out the lotion paper tissues 21 from the package 1, but is preferably provided at the center of the package base material 10 above the lotion tissue laminate 11, extending at a substantially right angle to the sealed portion 12. The package base material 10 may also have a single line perforation 14 for forming the opening 15 for the lotion paper tissues 21, which may be formed by cutting the perforation 14 and opening the package when in use. The required number of lotion paper tissues 21 can be obtained by sequentially pulling out (taking out) the lotion paper tissues 21 from the opening 15 thus formed.

[0033] (Packaging base material) The packaging substrate 10 is a tubular film having at least a layer of textured polyethylene film as the outermost layer. The packaging substrate 10 preferably does not contain paper, and preferably has printing on it. The values ​​of basis weight and ash content described below include the values ​​of printing ink. The tubular film is a film in which a sheet-like film is formed into a cylindrical shape like a tube.

[0034] (tube film) The film constituting the tubular film has at least a layer of textured polyethylene film as the outermost layer. If the material of the outermost layer is other than textured polyethylene film, the touch of the film is inferior. The tubular film may be formed of a single layer or multiple layers, but multiple layers are preferred.

[0035] For layers other than the outermost layer, the film material can be any plastic (thermoplastic resin) film used for packaging ordinary paper products, and may be surface-treated, but milky white polyethylene film is preferable from the viewpoint of aesthetic appearance and slip resistance. Examples of the plastic film material include conventionally known thermoplastic resins such as polyolefin (polyethylene, polypropylene, etc.), polyester (PET, etc.), polyamide (nylon, etc.), polycarbonate, polystyrene, polyvinyl chloride, etc., and polyethylene is preferable.

[0036] Specifically, when the tube-type film is formed of multiple layers, it is preferable that the material of the film in the outermost layer of the film substrate is a textured polyethylene film, and the material of the film in the innermost layer is a milky polyethylene film. By using a textured polyethylene film for the outermost layer, the packaging substrate 10 has an appropriate strength and can be easily packaged tightly. In addition, if the innermost layer is a material other than a milky polyethylene film, the upper and lower parts of the laminate 11 are easily turned over during packaging.

[0037] The method of matte-finishing the film in the matte-finish polyethylene film, which is the outermost layer of the tubular film, is not particularly limited, and may be a conventionally known method, a method of pressing the surface of the tubular film against an embossing roll or a matte roll to give unevenness, or a method of giving unevenness by sandblasting. These methods may be performed during the molding of the tubular film, but it is preferable to perform them on a single layer of polyethylene to obtain a matte-finish polyethylene film, which is then laminated with a milky polyethylene film or the like as the innermost layer. In addition, it is also possible to employ, for example, a method of using a polymer blend or a method of biaxially stretching a laminate of a polyolefin resin blend without performing surface treatment as described above. In addition, it is preferable to laminate (extrusion laminate) the matte-finish film, which is the outermost layer, and the milky film, which is the innermost layer, to form a multilayer film.

[0038] The packaging substrate 10 of the present invention may have other layers in addition to the tube-type film layer. Examples of the other layers include a water vapor barrier layer, an oxygen barrier layer, a print layer, a printability improving layer, an overprint layer, and a light-shielding layer. These other layers can be provided, for example, on the surface in contact with the lotion tissue laminate 11 or on the surface exposed to the outside air, and may be one layer or two or more layers. Note that the layers described above are not related to the number of layers of the film.

[0039] It is preferable that the printed layer is provided between the outermost layer of the matte polyethylene film and the innermost layer of the milky white polyethylene film. By doing so, the lotion tissue laminate 11 is less likely to turn over during packaging while maintaining the good tactile feel of the film.

[0040] (Thickness of packaging material) The lower limit of the thickness of the packaging substrate 10 of the present invention is preferably 35 μm or more, more preferably 50 μm or more, and even more preferably 60 μm or more. The upper limit of the thickness of the packaging substrate 10 is preferably 100 μm or less, more preferably 90 μm or less, and even more preferably 80 μm or less. If the thickness is less than 35 μm, the stiffness of the packaging substrate 10 is weakened, and the packaging substrate 10 is difficult to spread when spread during packaging, and is easily rubbed against the laminate 11, which makes the lotion tissue paper 21 easily turn over. If the thickness exceeds 100 μm, the packaging substrate 10 is difficult to bend at an appropriate position, making it difficult to package tightly. The thickness of the packaging substrate 10 can be measured in accordance with JIS K7130.

[0041] (Circumference of packaging material) The lower limit of the circumference of the packaging substrate 10 is preferably 330 mm or more, more preferably 340 mm or more, and even more preferably 350 mm or more. The upper limit of the circumference of the packaging substrate 10 is preferably 430 mm or less, more preferably 415 mm or less, and even more preferably 405 mm or less. If the circumference is less than 330 mm, the upper and lower parts of the laminate 11 are likely to turn over during packaging. If the circumference exceeds 430 mm, the package 1 is less tight. The circumference of the packaging substrate 10 can be measured by cutting the packaging substrate 10 with a ruler. The circumference of the packaging substrate 10 is measured in the CD direction of the film.

[0042] (Ash content of packaging materials) The ash content of the packaging substrate 10 is 1.5% or more and 12.0% or less. If the ash content is less than 1.5%, the upper and lower parts of the laminate 11 are likely to turn over during packaging. If the ash content exceeds 12.0%, the stiffness of the packaging substrate 10 weakens as the ash content increases, and the packaging substrate 10 is less likely to spread when unfolded during packaging, and is more likely to rub against the laminate 11, which makes the lotion tissue paper 21 more likely to turn over. The lower limit of the ash content of the packaging substrate 10 is preferably 2.0% or more, more preferably 2.5% or more. The upper limit is preferably 10.0% or less, more preferably 8.0% or less.

[0043] Ash content refers to the percentage of minerals such as calcium, iron, sodium, magnesium, phosphorus, and potassium, and can be measured in accordance with JIS P 8251. The ash content is calculated using the following formula, but the bone dry mass of the test piece is not measured; instead, the mass of the test piece of packaging substrate 10 when conditioned at 23°C and 50% humidity is regarded as the bone dry mass. Ash content (%) = mass of residue (g) ÷ bone dry mass of test piece (g) × 100

[0044] It should be noted that since it is not possible to remove only the printing ink from the film, the ash content of the packaging substrate 10 is measured using the film including the printing, and this value is regarded as the ash content of the packaging substrate 10 (as in Comparative Example 1 shown in Table 3 below, even a film that does not use a milky film contains 0.8% ash, and this is the ash content derived from the ink).

[0045] (Titanium oxide content in ash) The content of titanium oxide contained in the ash of the packaging substrate 10 is preferably 50% or more. If the content of titanium oxide is less than 50%, the laminate 11 does not slide properly on the packaging substrate 10, and as a result, the upper and lower parts are easily turned over during packaging. The content of titanium oxide contained in the ash of the packaging substrate 10 is more preferably 55% or more, and even more preferably 60% or more. The content of titanium oxide can be measured by elemental analysis.

[0046] (Lotion Tissue Paper 21) 3 is a perspective view showing an example of a lotion tissue laminate 11 packaged in the packaging body 1 of the present invention. The lotion tissue paper 21 and the lotion tissue laminate 11 will be described in detail below.

[0047] The lotion paper tissue 21 included in the lotion tissue laminate 11 is made by impregnating a medical solution (lotion) into thin paper. The lotion paper tissue 21 may be one ply or two ply, but is preferably two ply.

[0048] (Lotion content) The lotion content in the lotion paper tissue 21 is preferably 10% or more and 22% or less. If the lotion content is less than 10%, the feel of the lotion tissue is inferior. If the lotion content exceeds 22%, the strength of the lotion paper tissue 21 decreases and the upper and lower parts of the laminate 11 tend to turn up. The lower limit of the lotion content in the lotion paper tissue 21 is more preferably 12% or more, and even more preferably 14% or more. The upper limit is more preferably 19% or less, and even more preferably 17% or less.

[0049] The lotion liquid preferably contains glycerin and silicone, and more preferably the silicone is amino-modified silicone. When the lotion liquid contains the above-mentioned compound, the lotion tissue laminate 11 becomes smooth and the laminate 11 is less likely to turn over during packaging.

[0050] The lotion content per ply of lotion tissue paper 21 is 1.8 g / m 2 More than 3.2g / m 2 The preferred lotion content per ply is 1.8 g / m 2 If the lotion content per ply is less than 3.2 g / m, the feel of the tissue as a lotion tissue is inferior. 2 If the lotion content exceeds 2.1 g / m, the strength of the lotion paper tissue 21 will decrease and the upper and lower parts of the laminate 11 will be easily turned up. 2 More preferably, 2.4 g / m or more 2 More preferably, the upper limit is 3.0 g / m 2 Less than 2.7 g / m is more preferable. 2 The following is even more preferred:

[0051] The lotion content in the lotion tissue paper 21 and the lotion content per ply are measured as follows. 5 g of the lotion tissue paper 21 is collected, dried in a dryer (105°C) for 120 minutes, then cooled in a desiccator for 30 minutes, and the mass is measured. The measured mass at this time is designated as M1. Next, Soxhlet extraction is performed for 4 hours using the lotion tissue paper 21 whose mass has been measured and 150 ml of an extraction solvent (acetone:ethanol = 1:1). The obtained extract is heated and concentrated in a hot water bath, dried in a dryer (105°C) for 90 minutes, and then cooled in a desiccator for 30 minutes, and the mass is measured. The measured mass at this time is designated as M2. Then, using the two measured masses M1 and M2 obtained, M2 / M1 x 100 (%) is determined as the chemical solution content (lotion content [%]). Also, basis weight per ply x lotion content = chemical solution content (lotion content per ply) (g / m 2 )

[0052] (Basic weight) The lower limit of the basis weight per ply of lotion tissue paper 21 is 12 g / m 2 More than 14g / m is preferable. 2 More preferably, 16 g / m 2 The upper limit of the basis weight per ply of the lotion tissue paper 21 is 20 g / m 2 Less than 19 g / m is preferred 2 Less than 18g / m is more preferable. 2 More preferably, the basis weight is 12 g / m 2 If the basis weight is less than 20 g / m, the feel of the lotion tissue will be inferior, and the strength of the lotion tissue paper 21 will be low, making the upper and lower parts of the laminate 11 prone to curling up. 2 If the weight exceeds this value, the feel of the lotion tissue will be poor. The basis weight per ply of the lotion tissue paper 21 is measured in accordance with JIS P 8124.

[0053] (paper thickness) The lower limit of the thickness of the lotion paper tissue 21 is preferably 0.50 mm / 10 sheets or more, more preferably 0.55 mm / 10 sheets or more, and even more preferably 0.60 mm / 10 sheets or more. The upper limit of the thickness of the lotion paper tissue 21 is preferably 0.90 mm / 10 sheets or less, more preferably 0.82 mm / 10 sheets or less, and even more preferably 0.75 mm / 10 sheets or less. If the thickness is less than 0.50 mm / 10 sheets, the feel of the lotion paper tissue is inferior, and the strength of the lotion paper tissue 21 is also reduced, making the upper and lower parts of the laminate 11 more likely to turn up. If the thickness exceeds 0.90 mm / 10 sheets, the feel of the lotion paper tissue is inferior.

[0054] The thickness of the lotion paper tissues 21 (10 sheets) is measured using a thickness gauge (a dial thickness gauge "PEACOCK" manufactured by Ozaki Manufacturing Co., Ltd.). The measurement conditions are a measurement load of 3.7 kPa, a gauge diameter of 30 mm, a sample is placed between the gauge and the measuring table, and the gauge is read when the gauge is lowered at a speed of 1 mm or less per second. If the lotion paper tissues 21 are two-ply, five sets of two-ply lotion paper tissues 21 are stacked and measured for 10 sheets, and the thickness of the 10 sheets is calculated. The measurement is also repeated 10 times (measure 10 different places instead of measuring the same place 10 times), and the average of the measurement results is used as the final paper thickness.

[0055] (specific volume) The lower limit of the specific volume of lotion tissue paper 21 is 3.0 cm 3 / g or more is preferable, and 3.3 cm 3 / g or more is more preferable, and 3.6 cm 3 The upper limit of the specific volume of the lotion paper tissue 21 is 5.7 cm 3 / g or less is preferable, and 5.2 cm 3 / g or less is more preferable, and 4.7 cm 3 / g or less is more preferable. 3 / g or less than 5.7 cm 3If the thickness exceeds 1 / g, the feel of the lotion tissue is inferior. The specific volume of the lotion tissue paper 21 is calculated by dividing the thickness of the lotion tissue paper 21 by the basis weight, and is expressed as the volume cm per unit g. 3 It is expressed as:

[0056] (tensile strength in pulling direction) The tensile strength of the lotion paper tissue 21 in the direction of pulling from the take-out opening 15 is preferably 2.3 N / 25 mm or more and 4.0 N / 25 mm or less. If the tensile strength is less than 2.3 N / 25 mm, the upper and lower parts of the laminate 11 are likely to turn over during packaging. If the tensile strength exceeds 4.0 N / 25 mm, the feel of the lotion paper tissue is inferior. The lower limit of the tensile strength of the lotion paper tissue 21 in the direction of pulling from the take-out opening 15 is more preferably 2.7 N / 25 mm or more, and even more preferably 3.0 N / 25 mm or more. The upper limit is more preferably 3.6 N / 25 mm or less, and even more preferably 3.5 N / 25 mm or less. The tensile strength is measured in accordance with JIS P 8113, and the pulling speed is 300 mm / min.

[0057] (Tensile strength perpendicular to the pulling direction) The tensile strength of the lotion paper tissue 21 in a direction perpendicular to the direction of pulling out from the take-out opening 15 (direction perpendicular to the take-out opening) is preferably 0.8 N / 25 mm or more and 1.5 N / 25 mm or less. If the tensile strength is less than 0.8 N / 25 mm, the upper and lower parts of the laminate 11 are likely to be turned up during packaging. If the tensile strength exceeds 1.5 N / 25 mm, the feel of the lotion paper tissue is inferior. The lower limit of the tensile strength of the lotion paper tissue 21 in a direction perpendicular to the direction of pulling out from the take-out opening 15 is more preferably 0.9 N / 25 mm or more, and even more preferably 1.0 N / 25 mm or more. The upper limit is more preferably 1.4 N / 25 mm or less, and even more preferably 1.3 N / 25 mm or less. The tensile strength of the lotion paper tissue 21 in the direction of pulling out from the take-out opening 15 and in the direction perpendicular to the pull-out direction are measured in accordance with JIS P 8113, and the pulling speed is 300 mm / min.

[0058] (Kinematic friction coefficient) The dynamic friction coefficient between the packaging substrate 10 and the lotion tissue paper 21 is preferably 0.10 or more and 0.20 or less. If the dynamic friction coefficient is less than 0.10, the laminate 11 is slippery on the packaging substrate 10 and unstable, making it difficult to pack tightly. If the dynamic friction coefficient exceeds 0.20, the laminate 11 is not sufficiently slippery on the packaging substrate 10, and the upper and lower portions are easily turned up during packaging. The lower limit of the dynamic friction coefficient between the packaging substrate 10 and the lotion tissue paper 21 is more preferably 0.12 or more, and even more preferably 0.14 or more. The upper limit is more preferably 0.17 or less, and even more preferably 0.16 or less.

[0059] (Static friction coefficient) The static friction coefficient between the packaging substrate 10 and the lotion tissue paper 21 is preferably 0.14 or more and 0.24 or less. If the static friction coefficient is less than 0.14, the laminate 11 is slippery on the packaging substrate 10 and unstable, making it difficult to pack tightly. If the static friction coefficient exceeds 0.24, the laminate 11 is not slippery enough on the packaging substrate 10, and the upper and lower parts are easily turned up during packaging. The lower limit of the static friction coefficient between the packaging substrate 10 and the lotion tissue paper 21 is more preferably 0.16 or more, and even more preferably 0.18 or more. The upper limit is more preferably 0.21 or less, and even more preferably 0.20 or less.

[0060] The above-mentioned dynamic friction coefficient and static friction coefficient can be measured in accordance with ISO 15359 using an "Automatic Friction Tester NSF-100" manufactured by Nomura Shoji Co., Ltd. The friction coefficient is measured three times, but in the present invention, the static friction coefficient is measured from the first measurement, and the dynamic friction coefficient is measured from the third measurement.

[0061] Specifically, the measurement is performed as follows using a measuring device 200 shown in Fig. 5. First, the lotion tissue laminate 11 is gently removed from the lotion tissue paper package 1. Next, a sample (a packaging substrate sample 110 as a test piece) of 16 cm in the long side direction x 6 cm in the short side direction (the long side direction is the MD direction of the packaging substrate 10, and the short side direction is the CD direction of the packaging substrate 10) is cut and collected from the packaging substrate 10 of the package 1, and attached to the upper surface of a table 201 of the measuring device 200 so that the inner surface of the packaging substrate 10 (the surface in contact with the lotion tissue laminate 11) becomes the measurement surface. Note that the packaging substrate sample 110 may include a perforation 14 or the like on the bottom surface, and in that case, the measurement is performed with the perforation 14 or the like included.

[0062] Next, one set of lotion paper tissues 21 from the 20th set from the bottom is taken from the lotion tissue laminate 11. If the 20th set from the bottom has many wrinkles, the lotion paper tissues 21 just before or after the 20th set from the bottom (the 19th or 21st set from the bottom) may be used. This set (two sheets) is returned to the original folded state (four sheets). Then, a sample (tissue sample 111 as a test piece) of 16 cm x 6 cm (16 cm is the direction in which the lotion paper tissue laminate 11 is inserted into the packaging substrate 10, and 6 cm is the direction perpendicular to this) is cut so as not to include the creases, and attached to the underside of the sled 202. At this time, the lotion paper tissues 21 are cut in the same direction as when the lotion paper tissue laminate 11 is inserted into the packaging substrate 10 in the actual machine, and both ends in the 16 cm direction are cut so as not to affect the measurement.

[0063] When the measurement is started and the table 201 is moved while the packaging substrate sample 110 and the tissue sample 111 are in contact with each other, the sample begins to slip when the frictional force of the sample contact surface reaches its limit relative to the amount of movement of the table 201. The static and kinetic friction coefficients are derived based on the value of the load cell 203 at this time. The static and kinetic friction coefficients are measured three times using the same sample, with the first value being used for the static friction coefficient and the third value being used for the kinetic friction coefficient. The measurement is then repeated five times (one measurement is made with one packaging body 1, and five measurements are made with five packaging bodies 1) and the average value is used.

[0064] (Lotion tissue laminate 11) Although there is no particular limitation on the way in which the lotion paper tissues 21 included in the lotion tissue laminate 11 are folded in a V shape, it is preferable that they are laminated in a V shape. By folding in a V shape, the package 1 can be made such that the upper and lower parts of the laminate 11 are less likely to turn over during packaging. Also, it is preferable that the lotion paper tissues 21 are folded in a V shape using an interfolder. When the lotion paper tissues 21 are folded in a V shape using an interfolder, the pulling direction of the lotion paper tissues 21 when they are pulled out of the package 1 is the MD direction of the lotion paper tissues 21.

[0065] (Lotion tissue stack height) The lower limit of the height of the lotion tissue laminate 11 is preferably 50 mm or more, more preferably 55 mm or more, and even more preferably 60 mm or more. The upper limit is preferably 100 mm or less, more preferably 90 mm or less, and even more preferably 82 mm or less. If the height of the lotion tissue laminate 11 is less than 50 mm, the lotion tissue paper 21 will be used up quickly, and the frequency of replacing the lotion tissue paper package 1 will be reduced. If the height exceeds 100 mm, the lotion tissue paper 21 will be more likely to drop back when the number of sets inside the package 1 is reduced due to the use of the lotion tissue paper 21, since the distance from the take-out opening 15 will increase.

[0066] The height of the lotion tissue laminate 11 is measured as follows. After cutting the packaging substrate 10 of the lotion tissue paper package 1 and gently removing the lotion tissue laminate 11, a 30 cm ruler (Silver straight scale JIS Class 1, stainless steel, 64 g, manufactured by Shinwa Sokutei Co., Ltd.) is placed at the center of the short side direction of the laminate 11 along the long side direction of the laminate 11, and the height of both ends of the laminate 11 is measured. Similarly, a 30 cm ruler is placed at the center of the long side direction of the laminate 11 along the short side direction of the laminate 11, and the height of both ends of the laminate 11 is measured. These four values ​​are averaged to determine the final height of the laminate.

[0067] (Number of sets of lotion tissue paper) When the lotion paper tissues 21 are two-ply, the number of sets of the lotion paper tissues 21 contained in the lotion tissue laminate 11 is 170 sets or more and 320 sets or less. If the number of sets is less than 170 sets, the number of sets of the lotion paper tissues 21 is too small and they are used up quickly, so the frequency of replacing the lotion paper tissue package 1 is low. If the number of sets exceeds 320 sets, when the lotion paper tissues 21 are used and the number of sets inside the package 1 decreases, the distance from the take-out opening 15 increases, so the lotion paper tissues 21 are likely to drop back. The lower limit of the number of sets of the lotion paper tissues 21 contained in the lotion tissue laminate 11 is preferably 190 sets or more, and more preferably 220 sets or more. The upper limit is preferably 280 sets or less, and more preferably 260 sets or less.

[0068] (Circumference of lotion tissue paper) The lower limit of the circumference of the lotion tissue laminate 11 is preferably 245 mm or more, more preferably 315 mm or more, and even more preferably 330 mm or more. The upper limit of the circumference of the lotion tissue laminate 11 is preferably 410 mm or less, more preferably 395 mm or less, and even more preferably 380 mm or less. If the circumference is less than 245 mm, the lotion tissue paper 21 will be used up quickly, and the lotion tissue paper package 1 will not be replaced as frequently. If the circumference exceeds 410 mm, when the lotion tissue paper 21 is used and the number of sets inside the package 1 is reduced, the lotion tissue paper 21 will be more likely to drop back because the distance from the take-out opening 15 will increase.

[0069] The circumference of the lotion tissue laminate 11 is measured as follows. The packaging base material 10 of the lotion tissue paper package 1 is cut, and the lotion tissue laminate 11 is gently taken out. A 30 cm ruler (Silver straight scale JIS Class 1, stainless steel, 64 g, manufactured by Shinwa Sokutei Co., Ltd.) is placed at the center of the long side of the laminate 11 along the short side of the laminate 11, and the length of the top surface and the heights of both ends of the laminate 11 are measured. The final circumference of the lotion tissue laminate 11 is determined by adding up the two values ​​of the length of the top surface x 2 + the heights of both ends.

[0070] (Perimeter of packaging base material / Perimeter of laminate) The ratio calculated by (perimeter of packaging substrate 10 / perimeter of lotion tissue laminate 11)×100(%) is preferably 101% or more and 113% or less. If the ratio is less than 101%, the upper and lower parts of laminate 11 are likely to turn over during packaging. If the ratio exceeds 113%, the package 1 is less tight. The lower limit of the above ratio is more preferably 103% or more, and even more preferably 105% or more. The upper limit is more preferably 110% or less, and even more preferably 108% or less.

[0071] (packaging format) The packaging form of the packaging body 1 according to the present invention is gusset packaging.

[0072] As shown in Fig. 4, gusset packaging is a packaging format in which the packaged item (laminate 11) is inserted into the inside of a packaging base material 10, which is formed into a cylindrical shape with both ends of the bottom or mouth folded inward to match the length (height) of the bag and sealed at one end with a seal part 12, through an insertion opening 13, and then sealed horizontally by heat sealing or the like, and cut into individual bags at the sealed part. This gusset packaging can be performed using a known device. Alternatively, the laminate 11 may be inserted in a state in which the packaging base material 10 at the insertion opening 13 is turned outward so as not to be rolled inward.

[0073] Although the present invention has been described above using the embodiments, it goes without saying that the technical scope of the present invention is not limited to the scope described in the above embodiments. It is clear to those skilled in the art that various modifications or improvements can be made to the above embodiments. In addition, it is clear from the description of the claims that forms with such modifications or improvements can also be included in the technical scope of the present invention. EXAMPLES

[0074] The present invention will be described in detail below with reference to examples. However, the present invention is not limited to the examples shown below.

[0075] <Example> (Packaging base material) For example, the packaging material of Example 3 was produced as follows. A film with a multi-layer (three-layer) structure (the outermost layer is a textured polyethylene film, and the innermost layer is a milky polyethylene film, which are bonded by extrusion lamination) was prepared as a film substrate and used as it is as a packaging substrate. The film was printed. The basis weight, thickness, and density of the packaging substrate were measured and the results are shown in Table 1.

[0076] (Lotion tissue paper packaging (gusset packaging)) Packaging was performed using a film with a circumference of 380 mm (CD direction, front width 116 mm, fold width 37 mm each) and a pitch of 310 mm (MD direction) as the packaging substrate. A lotion tissue laminate consisting of 240 sets of lotion tissue paper was placed in this film packaging substrate, and sealed using gusset packaging to obtain a lotion tissue paper package. The paper product was wrapped and packaged in a tube-shaped film (packaging substrate). After the lotion tissue laminate was inserted, the excess in the pitch direction was cut off to produce the package.

[0077] For the lotion tissue paper package, the circumference of the packaging base material (A) and the circumference of the lotion tissue laminate (B) were measured before packaging, and the ratio of A to B (A / B (%)) was calculated by calculating A / B×100 from the measured A and B.

[0078] (Difficulty in dropping back) Thirty test subjects evaluated the ease of dropping back the lotion tissue paper packages we created by selecting either "difficult to drop back" or "easy to drop back." The evaluation criteria were as follows: 5: More than 29 testers rated it as difficult to drop back 4: 27 to 28 people rated the dropback as difficult 3: 25 to 26 people rated the dropback as difficult 2: 22 to 24 monitors rated it as difficult to drop back 1: Fewer than 21 people rated it as difficult to drop back

[0079] (Low frequency of replacement) Thirty test subjects evaluated the frequency of replacement of the lotion tissue paper packages they had created by choosing between "low frequency of replacement" and "high frequency of replacement." The evaluation criteria were as follows: 5: More than 29 monitors rated the replacement frequency as low 4: 27 to 28 monitors rated the frequency of replacement as low 3: The number of monitors who rated the replacement frequency as low is between 25 and 26. 2: 22 to 24 monitors rated the replacement frequency as low 1: Fewer than 21 monitors rated the replacement frequency as low

[0080] (The feel of lotion tissue) Thirty monitors evaluated the feel of the lotion tissue paper of the lotion tissue paper packaging produced, choosing between "The lotion tissue paper is soft and has an excellent feel" and "The feel is poor." The evaluation criteria are as follows: 5: More than 29 monitors rated the lotion tissue paper as soft and pleasant to the touch. 4: 27 to 28 monitors rated the lotion tissue paper as soft and had a good texture 3: Between 25 and 26 monitors rated the lotion tissue paper as soft and with an excellent texture 2: 22 to 24 monitors rated the lotion tissue paper as soft and had a good texture 1: Fewer than 21 monitors rated the lotion tissue paper as soft and pleasant to the touch

[0081] (Tightness of packaging) Thirty testers evaluated the tightness of the lotion tissue paper packages we created by choosing between "excellent tightness of the package" and "poor tightness of the package." The evaluation criteria are as follows: 5: More than 29 monitors rated the tightness of the packaging as excellent 4: 27 to 28 people rated the tightness of the packaging as excellent 3: 25 to 26 monitors rated the tightness of the packaging as excellent 2: 22 to 24 monitors rated the tightness of the packaging as excellent 1: Fewer than 21 monitors rated the tightness of the packaging as excellent

[0082] (Resistance of tissue laminate to curl during packaging) The lotion tissue paper packages thus produced were evaluated for resistance to curling of the lotion tissue laminate. The evaluation criteria were as follows: 5: The lotion tissue paper hardly turned over during packaging, and packaging went very smoothly. 4: The lotion tissue paper turned over slightly during packaging, but the packaging went smoothly. 3: The lotion tissue paper came off a little when wrapping, but I was able to wrap it. 2: The lotion tissue paper was turned over during packaging, but it was not a problem. 1: Many of the lotion tissue papers were peeled off during packaging, making the product inferior.

[0083] (Example 1) to (Example 19), (Comparative Example 1) to (Comparative Example 9) In Examples 1 to 19 and Comparative Examples 1 to 9, packaging substrates having the physical properties shown in Tables 1 to 3 were prepared in the same manner as in Example 3, and lotion tissue paper packages (gusset packaging) were prepared using these in the same manner as in Example 3, and the above-mentioned evaluations were performed.

[0084] [Table 1]

[0085] [Table 2]

[0086] [Table 3]

[0087] As is clear from the results shown in Tables 1 to 3, the packages of Examples 1 to 19 were all less prone to drop back, less frequently replaced, had excellent lotion tissue feel and tightness of the package, and the laminate was also less prone to curling up. In contrast, Comparative Examples 1 to 9 were all inferior in any of the laminate's resistance to curling up, resistance to drop back, less frequently replaced, lotion tissue feel, and tightness of the package.

[0088] From the above, according to this embodiment, it was confirmed that the present invention can provide a lotion tissue paper package in which lotion tissue paper with a pleasant feel is gusset-packaged with a tube-type film, which is less prone to drop back, requires less frequent replacement, has good tightness, and the lotion tissue paper is less likely to turn up during packaging.
