Description

[Technical Field]

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

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

[0003] In addition to rigid paper box cartons, tissue paper is also sold in soft packs made of soft paper or plastic film, which are convenient to carry. Among these, luxury lotion tissues are sometimes sold in caramel-wrapped soft packs.

[0004] Caramel packaging has a good shape (appearance) of the package, and because both ends of the package are heat-sealed, the shape of the soft pack package can be maintained even when the amount of lotion tissue remaining becomes small, making it easy to use until the lotion tissue is gone.

[0005] For example, Patent Document 1 discloses a tissue paper package using caramel packaging, which includes a sheet laminate in which multiple moisture-retaining sheets are stacked, and a packaging bag for packaging the sheet laminate, and the sheet laminate is contained 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.

[0006] However, while caramel packaging has a good packaging form, it is difficult to package because the height of the stack increases with increasing roll height when the original roll of sheet (tissue) is in the top roll, and decreases with increasing roll height when the original roll of sheet (tissue) is in the bottom roll.

[0007] If the height of the laminate is too high, it will be too tight and the packaging bag (film) and the laminate will interfere (contact) during packaging, causing strong friction, making the sheet (tissue) more likely to turn up, bend, and wrinkle, resulting in a lack of aesthetic appeal and a high likelihood of defective products.On the other hand, if the height of the laminate is too low, a gap will form between the packaging bag (film) and the laminate, making the laminate more likely to move inside the packaging bag (film), causing it to bend and wrinkle, resulting in a lack of operability and aesthetic appeal.

[0008] Furthermore, if the thickness of the packaging substrate film is too thick, it becomes difficult to bend the film at the desired position, making packaging difficult, whereas if the thickness of the film is too thin, the films will stick together, resulting in poor operability.

[0009] In particular, when embossed lotion tissue is used as the tissue, the friction may fluctuate, resulting in a significant deterioration in workability, and the tissue may be prone to wrinkling, resulting in a deterioration in cosmetic appearance. [Prior art documents] [Patent documents]

[Brief explanation of the drawings]

[0024] [Figure 1] 1 is a perspective view showing an example of a lotion tissue paper package and a lotion tissue laminate of the present invention. FIG. [Figure 2] FIG. 1 is a perspective view showing an example of a lotion tissue laminate packaged in the lotion tissue paper package of the present invention. [Figure 3] FIG. 1 is a schematic diagram of a measuring device for measuring the coefficient of friction between the packaging substrate and lotion paper tissue in the lotion paper tissue package of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0025] Hereinafter, the form for carrying out the present invention (hereinafter referred to as 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.

[0026] <Lotion tissue paper packaging> FIG. 1 is a perspective view showing an example of a lotion tissue paper package (hereinafter simply referred to as "package") 1 and a lotion tissue laminate (hereinafter simply referred to as "laminate") 11 of the present invention. The package 1 of the present invention has a laminate 11 made by laminating lotion tissue papers (hereinafter simply referred to as "sheet") covered with a packaging substrate 10 including at least a film substrate, and the laminate 11 is sealed with a seal part 12. The seal part 12 is preferably provided at the end where the packaging substrates 10 overlap, but may be formed in another location as long as the sealability of the package 1 (adhesion of the seal part 12) can be ensured. The packaging format using the packaging substrate 10 is caramel packaging (details of caramel packaging will be described later).

[0027] Furthermore, the package 1 preferably has an opening for removing the lotion paper tissues (not shown). This opening is preferably formed, for example, by having the packaging substrate 10 have a single perforation to form an opening for removing the lotion paper tissues, and by cutting the perforation to open the package at the time of use. By sequentially pulling out (removing) the lotion paper tissues from the opening thus formed, the required number of lotion paper tissues can be obtained. The perforation is not limited to a single line, and may be of any shape, such as a roughly circular or oval, as long as it makes it easy to remove the lotion paper tissues.

[0028] <Packaging base material> (Packaging substrate material) The packaging substrate 10 of the present invention includes at least a film substrate. Preferably, the packaging substrate 10 does not contain paper, and preferably has printing on it. The ash content value described below includes the value of the printing ink. Preferably, the packaging substrate 10 is a roll film (flat roll) type.

[0029] The film substrate may include a matte polyethylene film. The method for matte-finishing the film is not particularly limited, and conventionally known methods, methods for imparting irregularities by pressing the surface of a tubular film against an embossing roll or a matte roll, and methods for imparting irregularities by sandblasting can be used. These methods may be performed during the molding of the tubular film, but are preferably performed on a single layer of polyethylene to obtain a matte polyethylene film. Alternatively, methods such as using a polymer blend or biaxially stretching a laminate of a polyolefin resin blend can be used without performing such surface treatments.

[0030] Furthermore, the packaging substrate 10 may have other layers in addition to the film substrate layer. Examples of such other layers include a water vapor barrier layer, an oxygen barrier layer, a printing layer, a printability improving layer, an overprint layer, and a light-shielding layer. These other layers can be provided, for example, on the surface that contacts the lotion tissue laminate 11 or on the surface that is exposed to the outside air. Note that the layers described above are not related to the number of layers in the film. The printing layer can be on either the inside (the surface that contacts the lotion tissue paper) or the outside (the surface that is exposed to the outside air) of the film substrate; however, if it is on the inside, the printing may transfer to the lotion tissue paper, so the outside is preferred.

[0031] (Thickness of packaging substrate) The thickness of the packaging substrate 10 is 16 μm or more and 115 μm or less. If the thickness is less than 16 μm, the film of the packaging substrate 10 will stick together, resulting in poor operability. If the thickness exceeds 115 μm, the film of the packaging substrate 10 will be too thick, making it difficult to bend at the desired position, resulting in poor operability.

[0032] The lower limit of the thickness of the packaging substrate 10 is preferably 32 μm or more, more preferably 43 μm or more. The upper limit is preferably 90 μm or less, more preferably 70 μm or less. The thickness of the packaging substrate 10 can be measured in accordance with JIS K7130.

[0033] (Basis weight of packaging substrate) The basis weight of the packaging substrate 10 is 15 g / m 2 More than 100g / m 2 The basis weight is 15 g / m or less. 2 If the basis weight is less than 100 g / m, the packaging substrates 10 may stick together during operation, which may reduce the operability. 2 If the thickness exceeds this, the packaging substrate 10 becomes too thick, making it difficult to bend at the desired position, which may result in a decrease in workability.

[0034] The minimum basis weight is 30 g / m 2 More than 40g / m 2 More preferably, the upper limit is 80 g / m 2 Less than 60 g / m 2 The following is more preferable: The basis weight of the packaging substrate 10 can be measured in accordance with JIS P 8124.

[0035] (Perimeter of packaging substrate (A)) The lower limit of the perimeter (A) of the packaging substrate 10 is preferably 190 mm or more, more preferably 200 mm or more, and even more preferably 210 mm or more. The upper limit is preferably 275 mm or less, more preferably 260 mm or less, and even more preferably 240 mm or less. If the perimeter is less than 190 mm, the size of the package 1 will be small and too tight, making the laminate 11 prone to bending and wrinkling during packaging, resulting in poor cosmetic appearance. If the perimeter exceeds 275 mm, the size of the package 1 will be large, making the laminate 1 unstable inside the package 1 and prone to bending and wrinkling, resulting in poor cosmetic appearance.

[0036] The perimeter (A) of the packaging substrate 10 can be measured with a ruler by taking the remaining portion of the packaging substrate 10 cut when measuring the perimeter (B) of the laminate 11, which will be described later. In this case, the perimeter (A) of the packaging substrate 10 is the direction along the MD direction of the film. The packaging substrate 10 also has a heat-sealed portion in the perimeter direction (not shown), and although the packaging substrate 10 overlaps the heat-sealed portion, this overlap is not included in the measurement of the perimeter.

[0037] (Ash content of packaging substrate) The ash content of the packaging substrate 10 is preferably 0.05% or more and 5% or less. If the ash content is less than 0.05%, the strength of the packaging substrate 10 increases, making it less likely to bend during packaging. If the ash content exceeds 5%, the strength of the packaging substrate 10 decreases, resulting in poor shape stability in the package 1. The lower limit of the ash content of the packaging substrate 10 is more preferably 0.1% or more, and even more preferably 0.5% or more. The upper limit is more preferably 4% or less, and even more preferably 3% or less.

[0038] Ash content refers to the proportion 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 considered to be the bone-dry mass. Ash content (%) = mass of residue (g) ÷ bone dry mass of test piece (g) × 100 The ash content includes the ash content derived from the ink used to print the package.

[0039] <Lotion tissue laminate> 2 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 and the lotion tissue laminate 11 will be described in detail below.

[0040] <Lotion tissue paper> (Number of plies) The lotion tissue paper included in the laminate 11 is made by impregnating tissue paper with a lotion solution. The lotion tissue paper is three-ply. If the lotion tissue paper were two-ply or less, the height of the laminate 11 would be insufficient and additional sheets would be required. By using three-ply lotion tissue paper, the gaps between the sheets increase and the basis weight of the product ply (three-ply) increases, improving the stability of the shape of the laminate 11 (the paper thickness of the lotion tissue paper described below is measured under a constant load, so no difference is seen between two-ply and three-ply, but when it is made into the laminate 11, the gaps between the sheets increase in three-ply, making it more bulky, resulting in a difference in the height of the laminate 11).

[0041] (Embossed) The lotion tissue paper has an embossed pattern. If the lotion tissue paper does not have an embossed pattern, the thickness of the lotion tissue paper will be thin, resulting in an insufficient height for the laminate 11, and more paper will need to be used. The embossed pattern may be either single embossed or double embossed, but single embossed is preferred.

[0042] (size) The lower limit of the sheet size in the short side direction of the lotion tissue paper is preferably 110 mm or more, more preferably 120 mm or more, and even more preferably 135 mm or more, and the upper limit is preferably 220 mm or less, more preferably 200 mm or less, and even more preferably 180 mm or less.

[0043] The lower limit of the sheet size in the long side direction is preferably 130 mm or more, more preferably 150 mm or more, and even more preferably 170 mm or more, and the upper limit is preferably 235 mm or less, more preferably 215 mm or less, and even more preferably 195 mm or less.

[0044] If the sheet size in the short side direction is less than 110 mm or the sheet size in the long side direction is less than 130 mm, the size of the laminate 11 will be small and a gap will be formed between the packaging substrate 10 and the laminate 11, causing the laminate 11 to become unstable in the package 1 and shift, making the lotion tissue paper prone to bending and wrinkling, resulting in poor cosmetic appearance.If the sheet size in the short side direction exceeds 220 mm or the sheet size in the long side direction exceeds 235 mm, the size of the laminate 11 will be large and too tight, making the laminate 11 prone to bending and wrinkling during packaging, resulting in poor cosmetic appearance.

[0045] In this case, the short side direction of the lotion paper tissue means the direction parallel to the pitch direction (circumferential direction) of the packaging substrate 10 (i.e., the direction parallel to the Y axis shown in Figs. 1 and 2), and the long side direction of the lotion paper tissue means the direction parallel to the width direction of the packaging substrate 10 (i.e., the direction parallel to the X axis shown in Figs. 1 and 2). Furthermore, the lotion paper tissue is laminated in a state where it is folded in the short side direction, and the sheet size in the short side direction mentioned above is the size when unfolded. Note that the sheet size in the long side direction in Fig. 2 may be smaller than the sheet size in the short side direction, but even in that case, the definitions of the long side direction and the short side direction mentioned above will not change.

[0046] The short side direction of the lotion tissue paper is the MD direction when processed using IF, and the CD direction when processed using MF (multi-stand IF), but processing using IF is preferred. The short side direction of the lotion tissue paper is preferably folded approximately in half using a V-fold when processed (laminate).

[0047] (Lotion ingredient) The lotion solution (hereinafter simply referred to as "lotion") impregnated into the lotion tissue paper preferably contains glycerin and silicone, and the silicone is more preferably amino-modified silicone. When the lotion solution contains the above-mentioned compounds, the lotion tissue laminate 11 becomes smooth and has good shape stability.

[0048] (Lotion content (%)) The lotion content in the lotion tissue paper is preferably 10% or more and 22% or less. If the lotion content is less than 10%, when packaging the laminate 11 in the packaging substrate 10, it becomes difficult to slide, resulting in poor operability, and the laminate 11 is prone to bending and wrinkling, resulting in poor cosmetic appearance. If the lotion content exceeds 22%, the laminate 11 becomes slippery and unstable in the packaging 1, prone to bending and wrinkling, resulting in poor cosmetic appearance.

[0049] The lower limit of the lotion content in the lotion tissue paper is more preferably 12% or more, and even more preferably 13% or more, and the upper limit is more preferably 20% or less, and even more preferably 18% or less.

[0050] (Lotion content per 3 plies (g / m 2 )) The lotion content per 3 plies of lotion tissue paper is 4.3g / m 2 More than 9.6g / m 2 The preferred amount of lotion per 3 plies is 4.3 g / m 2 If the lotion content (%) is less than the lower limit, the laminate 11 will not slide well when packaged in the packaging substrate 10, resulting in poor operability, and the laminate 11 will be easily bent and wrinkled, resulting in poor cosmetic appearance. 2 If the amount of the lotion exceeds the upper limit and the lotion content (%) also exceeds the upper limit, the laminate 11 will slip and become unstable inside the package 1, and will be prone to bending and wrinkling, resulting in poor cosmetic appearance.

[0051] The lower limit of lotion content per 3 plies for lotion tissue paper is 5.2 g / m 2 More preferably, 6.2 g / m 2 More preferably, the upper limit is 8.3 g / m 2 Less than 7.6 g / m is more preferable. 2 The following is even more preferred:

[0052] The lotion content (%) of lotion tissue paper and the lotion content per 3 plies (g / m 2 ) is measured as follows: 5 g of lotion tissue paper is taken and dried in a dryer (105°C) for 120 minutes, then allowed to cool in a desiccator for 30 minutes, and the mass is measured. The measured mass at this time is designated M1. Next, Soxhlet extraction is performed for 4 hours using the lotion tissue paper whose mass has been measured and 150 ml of 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 allowed to cool in a desiccator for 30 minutes, and the mass is measured. The measured mass at this time is designated M2. Then, using the two measured masses M1 and M2, M2 / M1 x 100 (%) is determined as the chemical solution content (lotion content [%]). In addition, the basis weight (g / m2) per 3 plies is determined as follows: 2 ) x Lotion content (%) = Chemical content (Lotion content per 3 plies) (g / m 2 )

[0053] (Basic weight) The basis weight of the lotion tissue paper per 3 plies is 33 g / m 2 More than 61g / m 2 A basis weight of 33 g / m or less is preferred. 2 If the basis weight is less than 61 g / m, the height of the laminate 11 will be low, resulting in a gap between the packaging substrate 10 and the laminate 11 in the package 1, causing the laminate 11 to move and become unstable in the package 1, and it will be easily bent and wrinkled, resulting in poor cosmetic appearance. 2 If the thickness exceeds this value, the height of the laminate 11 will be too high, making it too tight, and the laminate 11 will be easily bent and wrinkled during packaging, resulting in poor cosmetic appearance.

[0054] The minimum basis weight for three plies of lotion tissue paper is 35 g / m 2 More preferably, 42 g / m 2 More preferably, the upper limit is 51 g / m 2 Less than 48g / m is more preferable. 2 The following is more preferable: The basis weight per three plies of lotion tissue paper is measured in accordance with JIS P 8124.

[0055] (paper thickness) The paper thickness per three plies of lotion tissue paper is preferably 0.18 mm or more and 0.34 mm or less. If the paper thickness is less than 0.18 mm, the height of the laminate 11 will be low, creating a gap between the packaging substrate 10 and the laminate 11 within the package 1, causing the laminate 11 to move and become unstable within the package 1, making it prone to bending and wrinkling, and reducing aesthetic appeal. If the paper thickness exceeds 0.34 mm, the height of the laminate 11 will be too high, making it too tight, making the laminate 11 prone to bending and wrinkling during packaging, reducing aesthetic appeal.

[0056] The lower limit of the thickness of the lotion tissue paper per three plies is more preferably 0.20 mm or more, and even more preferably 0.22 mm or more, and the upper limit is more preferably 0.29 mm or less, and even more preferably 0.27 mm or less.

[0057] The thickness of the lotion tissue paper per three plies is measured using a thickness gauge (a dial thickness gauge called "PEACOCK" manufactured by Ozaki Seisakusho Co., Ltd.). The measurement conditions are a measurement load of 3.7 kPa, a probe diameter of 30 mm, and a sample placed between the probe and the measuring table. The gauge is read when the probe is lowered at a speed of 1 mm per second or less. Three sets of three-ply lotion tissue paper (a total of nine plies) are then stacked and measured, and the result is divided by three to calculate the thickness per three plies proportionally. The measurement is also repeated 10 times (measurements are taken at 10 different locations, rather than the same location 10 times), and the average of the measurement results is used as the final paper thickness.

[0058] (specific volume) The lower limit of the specific volume of lotion tissue paper is 4.0 cm 3 / g or more is preferable, and 4.5cm 3 / g or more is more preferable, and 5.0cm 3 The upper limit is 7.0 cm / g or more. 3 / g or less is preferable, and 6.5cm 3 / g or less is more preferable, and 5.0cm 3 / g or less is more preferable. 3 If the specific volume is less than 7.0 cm3 / g, the laminate 11 will not have an embossed appearance and will require additional paper. Also, since the height of the laminate 11 is low, a gap will form between the packaging substrate 10 and the laminate 11 in the package 1, causing the laminate 11 to move and become unstable in the package 1, and it will be easily bent and wrinkled, resulting in poor aesthetic appeal. 3 If the thickness exceeds 1 / g, the height of the laminate 11 will be too high, and the laminate 11 will be too tight, and will be easily bent and wrinkled during packaging, resulting in poor cosmetic appearance. The specific volume of the lotion tissue paper is calculated by dividing the paper thickness of the lotion tissue paper by the basis weight, and is expressed as the volume cm per unit g. 3 It is expressed as:

[0059] <Lotion tissue laminate 11> (How to fold lotion tissue paper) There are no particular limitations on the way the lotion tissue paper included in the lotion tissue laminate 11 is folded, but it is preferable that it is folded in a V shape and laminated. By folding in a V shape, the packaging body 1 can be made to have excellent stability in the shape of the laminate 11.

[0060] (Number of pairs) When the lotion paper tissues are 3-ply, the number of sets of lotion paper tissues included in the laminate 11 is preferably 60 or more and 150 or less. If the number of sets is less than 60, the height of the laminate 11 will be low, which will create gaps between the packaging substrate 10 and the laminate 11 in the package 1, causing the laminate 11 to move and become unstable in the package 1, making it prone to bending and wrinkling and resulting in poor cosmetic appearance. If the number of sets exceeds 150, the height of the laminate 11 will be high, which will make it too tight, making the laminate 11 prone to bending and wrinkling during packaging and resulting in poor cosmetic appearance.

[0061] The lower limit of the number of sets of lotion paper tissues included in the laminate 11 is more preferably 75 sets or more, and even more preferably 90 sets or more. The upper limit is more preferably 130 sets or less, and even more preferably 110 sets or less.

[0062] (Height of laminate 11) The height of the lotion tissue laminate 11 is preferably 23 mm or more and 62 mm or less. If the height is less than 23 mm, the height of the laminate 11 will be low, creating a gap between the packaging substrate 10 and the laminate 11 within the package 1, causing the laminate 11 to move and become unstable within the package 1, making it prone to bending and wrinkling, and thus degrading cosmetic appearance. If the height exceeds 62 mm, the height of the laminate 11 will be high, making the packaging substrate 10 too tight, causing the laminate 11 to bend and wrinkling during packaging, degrading cosmetic appearance.

[0063] The lower limit of the height is more preferably 28 mm or more, and even more preferably 32 mm or more, and the upper limit is more preferably 53 mm or less, and even more preferably 50 mm or less.

[0064] The height of the laminate 11 can be measured as follows. After cutting the packaging substrate 10 of the package 1 and gently removing the laminate 11, a 30 cm ruler (Shinwa Measuring Co., Ltd., silver ruler, JIS Class 1, stainless steel, 64 g) is placed at the center of the short side of the laminate 11 along the long side 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 of the laminate 11 along the short side of the laminate 11, and the height of both ends of the laminate 11 is measured. The height measurements at these four points are averaged to determine the final height of the laminate 11.

[0065] (Perimeter (B) of laminate 11) The lower limit of the perimeter (B) in the short side direction of the lotion tissue laminate 11 is preferably 185 mm or more, more preferably 200 mm or more, and even more preferably 205 mm or more. The upper limit is preferably 265 mm or less, more preferably 245 mm or less, and even more preferably 240 mm or less. If the perimeter is less than 185 mm, the size of the laminate 11 will be small, a gap will form between the packaging substrate 10 and the laminate 11 in the package 1, the laminate 11 will move and become unstable in the package 1, and it will be prone to bending and wrinkling, resulting in poor cosmetic appearance. If the perimeter exceeds 265 mm, the size of the laminate 11 will be large and too tight, which will cause the laminate 11 to bend and wrinkling during packaging, resulting in poor cosmetic appearance.

[0066] The perimeter of the laminate 11 can be measured as follows: The packaging substrate 10 of the package 1 is cut, and the laminate 11 is gently removed. A 30 cm ruler (Shinwa Measuring Co., Ltd., silver ruler, JIS Class 1, stainless steel, 64 g) 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 height of both ends of the laminate 11 are measured. The final perimeter of the laminate 11 is determined by adding the values ​​obtained by multiplying the length of the top surface by 2 and the heights of both ends. Note that the heights of both ends of the laminate 11 may be determined by the measurements taken at two points in the center of the long side when measuring the height of the laminate 11 described above.

[0067] (Perimeter (A) / Perimeter (B)) It is preferable that the ratio calculated by (perimeter (A) of packaging base material 10 / perimeter (B) of laminate 11) × 100 (%) is 99% or more and 110% or less. If the ratio is less than 99%, the packaging body 1 will end up being too tight, causing the laminate 11 to bend and wrinkle easily, resulting in poor cosmetic appearance. If the ratio exceeds 110%, the packaging body 1 will end up not being tight enough, causing gaps to form between the packaging base material 10 and the laminate 11 inside the packaging body 1, causing the laminate 11 to move and become unstable inside the packaging body 1, making it prone to bend and wrinkle easily, resulting in poor cosmetic appearance.

[0068] The lower limit of the ratio (perimeter (A) / perimeter (B)) is more preferably 101% or more, and even more preferably 103% or more. The upper limit is more preferably 108% or less, and even more preferably 105% or less.

[0069] (mass of laminate) The lower limit of the mass of the lotion tissue laminate 11 is preferably 35 g or more, more preferably 75 g or more, and even more preferably 100 g or more. The upper limit is preferably 270 g or less, more preferably 230 g or less, and even more preferably 150 g or less. If the mass is less than 35 g, the height of the laminate 11 will be low, and a gap will be formed between the packaging substrate 10 and the laminate 11. This will cause the laminate 11 to become unstable in the package 1, causing it to shift, bend, and wrinkle, resulting in poor cosmetic appearance. If the mass exceeds 270 g, the height of the laminate 11 will be high, causing the packaging substrate 10 to become too tight, causing the laminate 11 to bend and wrinkle, resulting in poor cosmetic appearance.

[0070] The mass of the lotion tissue laminate 11 is determined by taking the lotion tissue laminate 11 from the package 1, adjusting the temperature at 23°C and 50% humidity, and then measuring it with an electronic balance.

[0071] (static friction coefficient) The static friction coefficient between the packaging substrate 10 and the lotion tissue paper is 0.15 or more and 0.27 or less. If the static friction coefficient is less than 0.15, the laminate 11 tends to slip on the packaging substrate 10 inside the package 1, causing the laminate 11 to move and become unstable, leading to bending and wrinkles, which deteriorates the cosmetic appearance. If the static friction coefficient exceeds 0.27, the friction is so high that the laminate 11 tends to bend and wrinkle, which deteriorates the cosmetic appearance.

[0072] The lower limit of the static friction coefficient is preferably 0.17 or more, more preferably 0.19 or more, and the upper limit is more preferably 0.25 or less, even more preferably 0.22 or less.

[0073] (dynamic friction coefficient) The dynamic friction coefficient between the packaging substrate 10 and the lotion tissue paper is preferably 0.11 or more and 0.23 or less. If the dynamic friction coefficient is less than 0.11, the laminate 11 tends to slip on the packaging substrate 10 inside the package 1, causing the laminate 11 to move and become unstable, and prone to bending and wrinkling, resulting in poor cosmetic appearance. If the dynamic friction coefficient exceeds 0.23, the friction between the laminate 11 and the packaging substrate 10 is so high that the laminate 11 tends to bend and wrinkling, resulting in poor cosmetic appearance.

[0074] The lower limit of the dynamic friction coefficient is preferably 0.13 or more, more preferably 0.14 or more, and the upper limit is more preferably 0.20 or less, even more preferably 0.19 or less.

[0075] The static friction coefficient and dynamic 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, and 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.

[0076] Specifically, the measurement is performed as follows using a measuring device 200 shown in Fig. 3. First, the lotion tissue laminate 11 is gently removed from the lotion tissue paper package 1. Next, a sample (a packaging substrate sample 110 serving as a test piece) measuring 16 cm in the long side direction and 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 out and collected from the packaging substrate 10 of the package 1, and attached to the upper surface of the 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 perforations on the bottom surface, in which case the measurement is performed with the perforations included.

[0077] Next, one set of lotion paper tissues, the twentieth set from the bottom, is taken from the lotion tissue laminate 11. If the twentieth set from the bottom has many wrinkles, lotion paper tissues just before or after the twentieth set from the bottom (the 19th or 21st set from the bottom) may be used. This set (three sheets) is returned to its original folded state (six sheets). A 16 cm x 6 cm sample (tissue sample 111, the test piece) is then cut out (16 cm in the short side direction (Y-axis direction) of the lotion tissue laminate 11, and 6 cm in the long side direction (X-axis direction) perpendicular to this) (it is not a problem if there is only one fold) and attached to the underside of the sled 202. At this time, the lotion tissue laminate 11 is oriented in the same direction as when it is inserted into the packaging substrate 10 in the actual machine, and both ends in the 16 cm direction are cut out so as not to affect the measurement.

[0078] When measurement begins and table 201 is moved while packaging substrate sample 110 and tissue sample 111 are in contact, the sample begins to slip when the frictional force on the sample contact surface reaches its limit relative to the amount of movement of table 201. The static and kinetic friction coefficients are calculated based on the value of 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. Measurements are then repeated five times for one package (five sets of lotion tissue paper around the 20th set from the bottom of package 1 are taken and each set is measured once, for a total of five times), and the average value is used.

[0079] (packaging format) The packaging form of the packaging body 1 according to the present invention is caramel packaging.

[0080] Caramel wrapping is a packaging format in which the item to be packaged is wrapped in a packaging substrate that extends in one direction along the item, or the item is placed into one axial end of a pre-formed cylindrical packaging substrate. Two opposing flap-shaped edges of the packaging substrate that extend beyond both ends of the item to be packaged are folded toward each other, and then two other opposing flap-shaped edges are similarly folded toward each other, and these folded portions are sealed by heat sealing or the like. Caramel wrapping is preferred for packaging laminated tissue paper, such as the package 1 of the present invention. This caramel wrapping can be performed using known equipment.

[0081] Although the present invention has been described above using 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 will be apparent to those skilled in the art that various modifications and improvements can be made to the above embodiments. Furthermore, it is clear from the claims that such modifications and improvements can also be included within the technical scope of the present invention. [Example]

[0082] The present invention will be described in detail below with reference to examples, but the present invention is not limited to the examples shown below.

[0083] Example 1 (Packaging base material) A single-layer film (matt-textured polyethylene film) was used as the packaging substrate, using a roll of film with a circumference (pitch) of 226 mm and a width of 225 mm, which met the specifications listed in Table 1. The film was printed.

[0084] (Lotion tissue laminate) Three-ply embossed lotion tissue paper sheets meeting the specifications shown in Table 1 were prepared, and 100 sets were stacked in a V-fold to prepare a lotion tissue laminate.

[0085] (Lotion tissue paper packaging) The lotion tissue paper package was obtained by packaging it with a packaging base material and sealing it with caramel packaging. For the lotion tissue paper package, after packaging, the perimeter (A) of the packaging base material and the perimeter (B) of the lotion tissue laminate were measured, and (A) / (B)×100 was calculated to determine the ratio of A to B (A / B (%)). The static and dynamic friction coefficients between the packaging base material and the lotion tissue paper were also measured. The following evaluations were then carried out.

[0086] (operability) For the evaluation of "operability," the operability including ease of packaging when the lotion tissue laminate was packaged in the packaging base material was evaluated. The evaluation criteria were as follows: 5: The packaging went smoothly. 4: It was a little difficult to wrap, but it went smoothly. 3: It was a little difficult to wrap, but I was able to do it. 2: It was difficult to wrap, but it wasn't a problem. 1: It was difficult to wrap and I was unable to wrap it.

[0087] (cosmetic) To evaluate "beauty," a sensory test was conducted by monitors to evaluate the appearance, such as the absence of wrinkles in the laminated body inside the lotion tissue paper package. Specifically, 30 monitors selected "excellent beauty" or "poor beauty" for the beauty of the tissue paper. The evaluation criteria were as follows: 5: More than 29 testers rated it as "excellent cosmetic effect." 4: 27 to 28 monitors rated the product as "excellent cosmetic quality" 3: 25 to 26 monitors rated the product as "excellent cosmetic quality" 2: 22 to 24 monitors rated the product as "excellent cosmetic quality" 1: Fewer than 21 testers rated the product as "excellent cosmetic quality"

[0088] (Example 2) to (Example 15), (Comparative Example 1) to (Comparative Example 5) In Examples 2 to 15 and Comparative Examples 1 to 9, packaging substrates, lotion paper tissues, and lotion paper tissue laminates that fulfilled the specifications shown in Tables 1 and 2 were prepared in the same manner as in Example 1, and lotion paper tissue packages were fabricated using these in the same manner as in Example 1, and the above-mentioned evaluations were carried out.

[0089] [Table 1]

[0090] [Table 2]

[0091] As is clear from the results shown in Tables 1 and 2, the packages of Examples 1 to 15 were all excellent in operability and aesthetic appeal. In contrast, the packages of Comparative Examples 1 to 5 were all poor in either operability or aesthetic appeal.

[0092] From the above, according to this example, it was confirmed that the present invention can provide a lotion tissue paper package that has good operability because the tissue laminate is smoothly packaged in the packaging base during production, even when the lotion tissue paper is soft, and that has aesthetic appeal because the tissue laminate does not bend or wrinkle inside the package during or after production.
