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] Among these, film packaging such as pocket type and soft packs is sometimes used for packaging lotion tissue paper. Lotion tissue paper wrapped in film is easy to carry, so it is often carried in a pocket or bag.

[0004] The most commonly used packaging formats for tissue paper soft packs are caramel wrap, pillow wrap, and gusset wrap. Caramel packaging maintains the shape of the package well, and even when placed in a pocket or bag where there is a lot of external pressure, it has less impact on the inner sheet.

[0005] However, when packaging caramel, the heat seal during packaging is not stable unless the product has a certain height, so the product height becomes bulky when placed in a pocket or bag. On the other hand, pillow packaging and gusset packaging do not require the product to be packaged at a certain height, so the product height can be set to make it easy to put in a pocket or bag.

[0006] For example, Patent Document 1 discloses an example of such a tissue paper packaging using pillow packaging. The pillow packaging bag contains multiple stacked sheets and has a pair of seal 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. 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, and the ratio of the paper component is 50% or more. When the sheet has one ply, the length of the outlet is 80% to 100% of the distance between the pair of seal portions in the longitudinal direction of the top surface. When the sheet has two or more plies, the length of the outlet is 70% to 90% of the distance between the pair of seal portions in the longitudinal direction of the top surface.

[0007] [Patent Document 1] Japanese Patent Publication No. 2022-115638 Summary of the Invention [Problem to be solved by the invention]

[0008] However, pillow packaging has poor shape retention, and external pressure directly affects the inner sheet. When pressure is applied from the outside, lotion tissue paper is prone to wrinkles and creases, resulting in a decrease in the cosmetic quality of the product.

[0009] Furthermore, since the strength of the pillow packaging is low, the sheet often tears when it is compressed or rubbed inside the pocket. On the other hand, if the strength of the sheet is increased to improve the resistance to wrinkles and tears, the sheet will then become hard, and the feel of the lotion tissue paper will deteriorate.

[0010] The present invention has been made in view of the above circumstances, and has an object to provide a lotion paper tissue package in which a laminate in which lotion paper tissue is laminated is packaged in a packaging base material including at least a film base material, the package being easy to carry, the texture and aesthetic appeal of the lotion paper tissue being good, and the package being tear-resistant.

[Brief explanation of the drawings]

[0022] [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 diagram illustrating a pillow package packaging form in the lotion tissue paper package of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0023] 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.

[0024] <Lotion tissue paper packaging> FIG. 1 is a perspective view showing an example of a lotion tissue paper package (hereinafter simply referred to as a "package") and a lotion tissue laminate (hereinafter simply referred to as a "laminate" or "clip") of the present invention. The package 1 of the present invention has a lotion tissue laminate 11 made by laminating lotion tissue papers (hereinafter simply referred to as a "sheet") covered with a packaging substrate 10 including at least a film substrate, and the lotion tissue 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 pillow packaging (details of pillow packaging will be described later).

[0025] Furthermore, the package 1 preferably has a take-out opening for taking out the lotion paper tissues (not shown). This take-out opening is preferably formed, for example, by having the packaging substrate 10 have a single perforation to form the take-out opening for 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 formed take-out opening, the required number of lotion paper tissues can be obtained. Note that 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 take out the lotion paper tissues.

[0026] (Packaging base material) The packaging substrate 10 includes at least a film substrate. Preferably, the packaging substrate 10 does not contain paper, and preferably has printing on it. The ash content values ​​described below include the value of the printing ink. The packaging substrate 10 is preferably a roll film (flat film) type.

[0027] The method for matte-finishing the film in the matte-finished polyethylene film contained in the film substrate is not particularly limited, and can be a conventionally known method, a method of pressing the surface of a tubular film against an embossing roll or matte roll to impart irregularities, or a method of imparting irregularities by sandblasting. These methods can 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-finished 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.

[0028] Furthermore, the packaging substrate 10 of the present invention may have other layers in addition to the film substrate layer. Examples of 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 that comes into contact with 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 printed layer can be on either the inside (the surface in contact with the lotion tissue paper) or the outside (the surface exposed to the outside air) of the film substrate, but if it is on the inside, the printing may transfer to the lotion tissue paper, so the outside is preferred.

[0029] The basis weight of the packaging substrate 10 is 30 g / m 2 More than 80g / m 2 The basis weight is preferably 30 g / m or less. 2 If the basis weight is less than 80 g / m, the strength of the packaging substrate 10 will be weak, and external pressure will be easily transmitted to the sheet, causing the sheet to wrinkle, resulting in a decrease in aesthetic appeal. At the same time, the sheet will be easily torn. 2 If the weight exceeds this, the package 1 becomes bulky and difficult to carry. The lower limit of the basis weight of the packaging substrate 10 is 40 g / m 2 More preferably, it is 50 g / m or more. 2 The upper limit is more preferably 70 g / m or more.2 More preferably, it is 60 g / m or less. 2 It is more preferable that the basis weight of the packaging substrate 10 is measured in accordance with JIS P 8124.

[0030] The thickness of the packaging substrate 10 is preferably 40 μm or more and 60 μm or less. If the thickness is less than 40 μm, the strength of the packaging substrate 10 is weakened, and external pressure is easily transmitted to the sheet, making the sheet prone to wrinkling, resulting in a decrease in aesthetic appeal. At the same time, the sheet is prone to tearing. If the thickness exceeds 60 μm, the package 1 becomes bulky and difficult to carry. The lower limit of the thickness of the packaging substrate 10 is more preferably 42 μm or more, and even more preferably 45 μm or more. The upper limit is more preferably 58 μm or less, and even more preferably 55 μm or less. The thickness of the packaging substrate 10 can be measured in accordance with JIS K7130.

[0031] The lower limit of the perimeter of the packaging substrate 10 is preferably 188 mm or more, more preferably 198 mm or more, and even more preferably 208 mm or more. The upper limit is preferably 270 mm or less, more preferably 260 mm or less, and even more preferably 250 mm or less. If the perimeter is less than 188 mm and the perimeter of the laminate 11 described below does not change, the packaging will be too tight, and the sheet will be compressed and prone to wrinkles, resulting in a decrease in aesthetic appeal. If the perimeter is more than 270 mm and the perimeter of the laminate 11 described below does not change, the laminate 11 will move within the packaging substrate 10, causing the sheet to wrinkle, resulting in a decrease in aesthetic appeal. The perimeter of the packaging substrate 10 can be measured with a ruler by taking the remainder of the packaging substrate 10 cut when measuring the perimeter of the lotion tissue laminate 11, which will be described later, and in this case, the perimeter of the packaging substrate 10 is the direction along the CD direction of the film. As will be described later, the packaging substrate 10 also has a center seal portion 14 in the pitch direction, and although the center seal portion 14 is overlapped by the packaging substrate 10, this overlap is not included in the measurement of the perimeter.

[0032] 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 package 1 becomes bulky and difficult to carry. If the ash content exceeds 5%, the strength of the packaging substrate 10 weakens, and external pressure is easily transmitted to the sheet, making the sheet prone to wrinkling, resulting in a decrease in aesthetic appeal. At the same time, the sheet is prone to tearing. The lower limit of the ash content of the packaging substrate 10 is preferably 0.01% or more, and even more preferably 0.5% or more. The upper limit is preferably 4% or less, and even more preferably 3% or less. 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 after conditioning 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.

[0033] (Lotion tissue paper and 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.

[0034] The lotion tissue paper included in the lotion tissue laminate 11 is made by impregnating a medical solution (lotion) into thin paper. The lotion tissue paper is made up of three plies. If the lotion tissue paper has two or fewer plies, the strength of the lotion tissue paper will be reduced, it will be prone to wrinkling, and its cosmetic properties will be reduced. At the same time, the lotion tissue paper will be prone to tearing. Also, if the lotion tissue paper has four or more plies, the lotion tissue paper will be bulky, making the package 1 difficult to carry.

[0035] Furthermore, the lotion tissue paper has an embossed pattern. If the lotion tissue paper does not have an embossed pattern, the texture of the lotion tissue paper will be poor. The embossed pattern may be either single embossed or double embossed, but single embossed is preferred.

[0036] The lower limit of the liquid chemical (lotion) content in the lotion tissue paper is preferably 12.0% or more, more preferably 13.0% or more, and even more preferably 14.0% or more. The upper limit is preferably 25.0% or less, more preferably 21.5% or less, and even more preferably 19.0% or less. If the liquid chemical content is less than 12.0%, the texture of the lotion tissue paper will deteriorate. If the liquid chemical content exceeds 25.0%, the strength of the lotion tissue paper will decrease, making it more prone to wrinkling and reducing its cosmetic value. At the same time, the lotion tissue paper will also be more prone to tearing.

[0037] The chemical solution (lotion) preferably contains glycerin and silicone, and the silicone is more preferably amino-modified silicone. When the chemical solution (lotion) contains the above compounds, the lotion tissue laminate 11 becomes smooth and has a good texture. The chemical solution content in the lotion tissue paper is measured as follows.

[0038] Five grams of lotion tissue paper was collected and dried in a dryer (105°C) for 120 minutes, then allowed to cool in a desiccator for 30 minutes, and its mass was measured. This measured mass was designated M1. Next, Soxhlet extraction was performed for four hours using the lotion tissue paper whose mass had been measured and 150 ml of extraction solvent (acetone:ethanol = 1:1). The resulting extract was 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 its mass was measured. This measured mass was designated M2. The two measured masses, M1 and M2, were then used to determine the drug solution content (lotion content [%]) as M2 / M1 × 100 (%).

[0039] The basis weight of the lotion tissue paper per 3 plies is 25 g / m 2 More than 50g / m 2 The basis weight per 3 plies is 25 g / m 2 If the weight is less than 50g / m², the strength of the lotion tissue paper will be low, it will be prone to wrinkling, and the cosmetic properties will be reduced. At the same time, the lotion tissue paper will be prone to tearing. 2 If the temperature exceeds this, the lotion tissue paper will become hard and its texture will deteriorate. The minimum basis weight for the three plies of lotion tissue paper is 28 g / m 2 It is preferable that the weight is 32 g / m or more. 2 The upper limit is more preferably 46 g / m or more. 2 Preferably, it is 42 g / m or less. 2 The basis weight per three plies of the lotion tissue paper is measured in accordance with JIS P 8124.

[0040] Furthermore, the paper thickness per 10 plies of the lotion tissue paper is 0.30 mm or more and 0.75 mm or less. If the paper thickness per 10 plies is less than 0.30 mm, the strength of the lotion tissue paper will be reduced, it will be prone to wrinkling, and its cosmetic appearance will be reduced. At the same time, the lotion tissue paper will be prone to tearing. If the paper thickness per 10 plies exceeds 0.75 mm, the lotion tissue paper will be bulky, making the package 1 difficult to carry. The lower limit of the thickness of the lotion tissue paper per 10 plies is preferably 0.35 mm or more, more preferably 0.40 mm or more, and the upper limit is preferably 0.70 mm or less, more preferably 0.60 mm or less.

[0041] The thickness of the lotion tissue paper per 10 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 thickness per 10 plies is calculated 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 thickness per 10 plies.

[0042] Furthermore, the specific volume of lotion tissue paper has a lower limit of 3.4 cm 3 / g or more is preferable, and 3.6cm 3 / g or more is more preferable, and 3.8cm 3 The upper limit is more preferably 4.9 cm / g or more. 3 / g or less, and 3 / g or less is more preferable, and 4.5cm 3 / g or less is more preferable. 3If the specific volume is less than 4.9 cm3 / g, the strength of the lotion tissue paper will be reduced, it will be prone to wrinkling, and the cosmetic properties will be reduced. At the same time, the lotion tissue paper will be prone to tearing. 3 If the weight ratio exceeds 1 / g, the lotion tissue paper will become bulky, making the package 1 difficult to carry. The specific volume of lotion tissue paper is calculated by dividing the thickness of the lotion tissue paper by the basis weight, and then calculating the volume cm per unit g. 3 It is expressed as:

[0043] The tensile strength (DMDT) in the MD direction of the lotion tissue paper per three plies in a dry state according to JIS P 8113 is 240 cN / 25 mm or more and 490 cN / 25 mm or less. The tensile strength (DCDT) in the CD direction of the lotion tissue paper per three plies in a dry state according to JIS P 8113 is 80 cN / 25 mm or more and 170 cN / 25 mm or less. If the DMDT is less than 240 cN / 25 mm or the DCDT is less than 80 cN / 25 mm, the strength of the lotion tissue paper is reduced, it is prone to wrinkling, and its cosmetic properties are reduced. At the same time, the lotion tissue paper is prone to tearing. If the DMDT exceeds 490 cN / 25 mm or the DCDT exceeds 170 cN / 25 mm, the lotion tissue paper becomes hard and its texture is poor.

[0044] The lower limit of the DMDT per three plies of lotion tissue paper is preferably 270 cN / 25 mm or more, more preferably 310 cN / 25 mm or more. The upper limit is preferably 450 cN / 25 mm or less, more preferably 410 cN / 25 mm or less. The lower limit of the DCDT per three plies of lotion tissue paper is preferably 90 cN / 25 mm or more, more preferably 100 cN / 25 mm or more. The upper limit is preferably 150 cN / 25 mm or less, more preferably 140 cN / 25 mm or less.

[0045] Furthermore, the GMT, which is the square root of the product of DMDT and DCDT per three plies of lotion tissue paper, is preferably 140 cN / 25 mm or more and 280 cN / 25 mm or less. If the GMT is less than 140 cN / 25 mm, the strength of the lotion tissue paper will be low, it will be prone to wrinkling, and its cosmetic properties will be reduced. At the same time, the lotion tissue paper will be prone to tearing. If the GMT exceeds 280 cN / 25 mm, the lotion tissue paper will become hard and its texture will be poor.

[0046] The GMT, which is the square root of the product of DMDT and DCDT per three plies of lotion tissue paper, has a lower limit of preferably 150 cN / 25 mm or more, more preferably 180 cN / 25 mm or more, and an upper limit of preferably 260 cN / 25 mm or less, more preferably 235 cN / 25 mm or less. The DMDT and DCDT per three plies of lotion tissue paper are measured as three plies in accordance with JIS P 8113. The GMT is calculated from the square root of the product of the DMDT and DCDT measured as described above.

[0047] Furthermore, the hand feel value (HF) of the outermost sheet surface of the lotion tissue paper, as measured by a tissue softness measuring device (TSA), is preferably 80 or more and 87 or less. If the hand feel value (HF) is less than 80, the feel of the lotion tissue paper will be poor. If the hand feel value (HF) exceeds 87, when a large amount of chemical solution is applied, the strength of the lotion tissue paper will be reduced, making it prone to wrinkling and reducing its cosmetic value. At the same time, the lotion tissue paper will be prone to tearing. The hand feel value (HF) of the outermost sheet surface of the lotion tissue paper, as measured by a tissue softness measuring device TSA, preferably has a lower limit of 82 or more, more preferably 83 or more, and an upper limit of 86 or less, more preferably 85 or less.

[0048] The smoothness (TS750) of the outermost sheet surface of the lotion tissue paper measured by the tissue softness measuring device TSA is 5.0 dBV. 2 rms above 13.0dBV 2 It is preferable that the rms level is less than 5.0 dBV. 2 If it is less than rms, wrinkles in the lotion tissue paper will be more noticeable, and the cosmetic effect will be poor. Smoothness (TS750) is 13.0 dBV 2 If it exceeds rms, the texture of the lotion tissue paper will deteriorate. The smoothness (TS750) of the outermost sheet surface of lotion tissue paper measured by the tissue softness measuring device TSA has a lower limit of 6.0 dBV. 2 rms or more is preferable, and 7.0 dBV 2 It is more preferable that the upper limit is 12.0 dBV. 2 rms or less is preferable, and 10.5 dBV 2 It is more preferable that it is rms or less.

[0049] The "outermost sheet surface" for measuring the hand feel value (HF) and smoothness (TS750) mentioned above refers to the front or back surface of the 3-ply lotion tissue paper. The measurement method for TS750 and HF using the Tissue Softness Measuring Device TSA and the measuring device used therein are disclosed in detail, for example, in JP 2013-236904 A. For various measurement methods using the Tissue Softness Measuring Device TSA, please refer to the above patent documents. The hand feel value (HF) and smoothness (TS750) values ​​are each measured twice on the front and back surfaces of three-ply lotion tissue paper, and the final value is the average of the measured values. Furthermore, the lotion tissue paper is used as a three-ply tissue for the measurement.

[0050] Furthermore, the value of DMDT divided by HF in the lotion tissue paper is preferably 2.8 or more and 5.9 or less. If the value is less than 2.8, the strength of the lotion tissue paper will be low, it will be prone to wrinkling, and its cosmetic properties will be reduced. At the same time, the lotion tissue paper will be prone to tearing. If the value exceeds 5.9, the texture of the lotion tissue paper will be poor. In the lotion tissue paper, the lower limit of the value obtained by dividing DMDT by HF is more preferably 3.2 or more, and even more preferably 3.7 or more, and the upper limit is more preferably 5.4 or less, and even more preferably 4.9 or less.

[0051] Furthermore, the value of DCDT divided by HF in the lotion tissue paper is preferably 0.9 or more and 2.0 or less. If the value is less than 0.9, the strength of the lotion tissue paper will be low, it will be prone to wrinkling, and its cosmetic properties will be reduced. At the same time, the lotion tissue paper will be prone to tearing. If the value exceeds 2.0, the texture of the lotion tissue paper will be poor. In lotion tissue paper, the lower limit of the value obtained by dividing DCDT by HF is more preferably 1.1 or more, and even more preferably 1.2 or more, and the upper limit is more preferably 1.8 or less, and even more preferably 1.6 or less.

[0052] In addition, the value of GMT divided by HF in the lotion tissue paper is preferably 1.6 or more and 3.4 or less. If the value is less than 1.6, the strength of the lotion tissue paper will be low, it will be prone to wrinkling, and its cosmetic properties will be reduced. At the same time, the lotion tissue paper will be prone to tearing. If the value exceeds 3.4, the texture of the lotion tissue paper will be poor. In lotion tissue paper, the lower limit of the value obtained by dividing GMT by HF is more preferably 1.8 or more, and even more preferably 2.1 or more, and the upper limit is more preferably 3.1 or less, and even more preferably 2.8 or less.

[0053] (Lotion tissue laminate) 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.

[0054] When the lotion paper tissues are three-ply, the number of lotion paper tissues contained in the lotion tissue laminate 11 is 20 or more and 80 or less. If the number of sets is less than 20, the strength of the laminate 11 as a whole will be low, the lotion paper tissues will be prone to wrinkling, and the cosmetic appearance will be reduced. At the same time, the lotion paper tissues will be prone to tearing. If the number of sets exceeds 80, the laminate 11 will be bulky, making the package 1 difficult to carry. The lower limit of the number of sets of lotion paper tissues included in the lotion tissue laminate 11 is preferably 30 or more, and more preferably 40 or more. The upper limit is preferably 70 or less, and more preferably 60 or less.

[0055] Furthermore, the height (clip height) of the lotion tissue laminate 11 is 6 mm or more and 25 mm or less. If the height is less than 6 mm, the overall strength of the laminate 11 will be low, the lotion tissue paper will be prone to wrinkling, and the cosmetic appearance will be reduced. At the same time, the lotion tissue paper will be prone to tearing. If the height exceeds 25 mm, the laminate 11 will be bulky, making the package 1 difficult to carry. The lower limit of the height of the lotion tissue laminate 11 is preferably 9 mm or more, and more preferably 13 mm or more. The upper limit is preferably 21 mm or less, and more preferably 18 mm or less. The height of the lotion tissue laminate 11 can be measured as follows.

[0056] The packaging substrate 10 of the lotion tissue paper package 1 is cut, and the lotion tissue laminate 11 is gently removed. Then, a 30 cm ruler (a silver ruler, JIS Class 1, stainless steel, 64 g, manufactured by Shinwa Measuring Co., Ltd.) 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. These four values ​​are averaged to determine the final height of the laminate 11.

[0057] Furthermore, the lower limit of the length of the short side of the lotion tissue laminate 11 is preferably 80 mm or more, more preferably 85 mm or more, and even more preferably 90 mm or more. The upper limit is preferably 110 mm or less, more preferably 105 mm or less, and even more preferably 100 mm or less. If the length of the short side is less than 80 mm and the circumferential length of the packaging substrate 10 does not change, the laminate 11 moves within the packaging substrate 10, making the sheet prone to wrinkling, resulting in a decrease in aesthetic appeal. If the length of the short side is more than 110 mm and the circumferential length of the packaging substrate 10 does not change, the packaging becomes too tight, making the sheet prone to wrinkling due to pressure, resulting in a decrease in aesthetic appeal. The length of the short side of the lotion tissue laminate 11 is measured by placing a 30 cm metal ruler along the short side of the laminate 11 and measuring the length from one end of the laminate 11 to the other. This measurement is carried out four times at different points, and these four values ​​are averaged to obtain the final length of the laminate 11 in the short side direction.

[0058] In this case, the short side direction of the lotion tissue laminate 11 means the direction parallel to the width 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 tissue paper means the direction parallel to the pitch direction of the packaging substrate 10 (i.e., the direction parallel to the X axis shown in Figs. 1 and 2). Furthermore, the length of the long side in FIG. 2 may be smaller than the length of the short side, but even in this case, the definitions of the long side and short side directions described above will not change.

[0059] The lower limit of the circumference of the lotion tissue laminate 11 is preferably 170 mm or more, more preferably 180 mm or more, and even more preferably 200 mm or more. The upper limit is preferably 260 mm or less, more preferably 250 mm or less, and even more preferably 245 mm or less. If the circumference is less than 170 mm and the circumference of the packaging substrate 10 does not change, the laminate 11 moves within the packaging substrate 10, making the sheet prone to wrinkling, resulting in a decrease in aesthetic appeal. If the circumference exceeds 260 mm and the circumference of the packaging substrate 10 does not change, the packaging becomes too tight, making the sheet prone to wrinkling due to pressure, resulting in a decrease in aesthetic appeal. In this case, the circumferential length of the lotion tissue laminate 11 refers to the circumferential length in the short side direction of the lotion tissue laminate 11, and can be measured as follows.

[0060] The packaging substrate 10 of the lotion tissue paper package 1 is cut, and the lotion tissue laminate 11 is gently removed. A 30 cm ruler (Shinwa Measuring Co., Ltd., straight silver, 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 circumference of the lotion tissue laminate 11 is determined by adding together the two values ​​obtained by multiplying the length of the top surface by 2 and the height of both ends.

[0061] It is preferable that the ratio calculated by (perimeter of packaging substrate 10 / perimeter of lotion tissue laminate 11) x 100 (%) is 97% or more and 113% or less. If the ratio is less than 97%, the packaging will be too tight, and the sheets will be compressed and prone to wrinkling, resulting in a decrease in aesthetic appeal. If the ratio exceeds 113%, the laminate 11 will move within the packaging substrate 10, making the sheets prone to wrinkling, resulting in a decrease in aesthetic appeal. The ratio calculated by (perimeter of packaging substrate 10 / perimeter of lotion tissue laminate 11) x 100 (%) has a lower limit of preferably 99% or more, and even more preferably 103% or more. The upper limit is preferably 110% or less, and even more preferably 106% or more.

[0062] (packaging format) The packaging form of the packaging body 1 according to the present invention using the packaging base material 10 is pillow packaging. If the packaging form is caramel packaging, the packaging body 1 becomes bulky and difficult to carry.

[0063] Pillow packaging is a packaging format in which, as shown in Figure 3, the packaging substrate is overlapped at both widthwise ends with the inner surfaces facing each other so as to encase the packaged item placed on or below the sheet-like packaging substrate in a cylindrical shape, and this overlapping portion is sealed with a center seal 14 to form a cylindrical shape, and the bottom or opening (insertion opening 13) is sealed in a horizontal line with seal 12 to match the length (height) of the bag, and this sealed portion is then cut into individual bags. This pillow packaging can be performed using known equipment.

[0064] There are two types of pillow packaging: vertical pillow packaging, in which the packaging substrate is fed vertically and the packaged item is filled from above while being wrapped, and horizontal pillow packaging, in which the packaging substrate is fed horizontally and the packaged item is wrapped. When packaging lotion tissue laminate 11, horizontal pillow packaging is preferred in terms of packaging speed and the shape of lotion tissue laminate 11. In this case, the seal type of the seal portion 12 and the center seal portion 14 is preferably heat seal.

[0065] 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]

[0066] 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.

[0067] Example 1 (Packaging base material) A single-layer film (matt-textured polyethylene film) was prepared as the film substrate and used as is as the packaging substrate. The film was printed. The thickness of the packaging substrate was measured and the results are shown in Table 1.

[0068] (Lotion tissue paper packaging (pillow packaging)) Packaging was performed using a film with a pitch of 270 mm and a width of 240 mm as the packaging base material (in the case of Example 1). A lotion tissue laminate, in which 40 pairs of lotion tissue papers were laminated as a paper product, was placed into the film as the packaging base material, and sealed with pillow packaging to obtain a lotion tissue paper package. For the lotion tissue paper package, the perimeter of the packaging substrate and the perimeter of the lotion tissue laminate were measured after packaging, and the ratio (perimeter of packaging substrate / perimeter of lotion tissue laminate) x 100 (%) was calculated from the measured perimeters of the packaging substrate and the lotion tissue laminate.

[0069] (Seat aesthetics) The cosmetic properties of the lotion tissue paper sheets (lotion tissue paper) in the prepared lotion tissue paper packages were evaluated by 30 monitors. The evaluation criteria are as follows, with 1 point being a failure and 2 points or more being a pass. 4: More than 28 monitors rated the seat as being aesthetically pleasing 3: 25 to 27 monitors rated the sheet as having excellent aesthetic appeal 2: 22 to 24 monitors rated the sheet as having excellent cosmetic properties 1: Fewer than 21 monitors rated the sheet as being aesthetically pleasing

[0070] (Sheet tear resistance) The manufactured lotion tissue paper packages were evaluated by 30 monitors for tear resistance of the packaged sheet (lotion tissue paper). The evaluation criteria are as follows, with 1 point being a failure and 2 points or more being a pass. 4: More than 28 testers rated the sheet as being strong and tear-resistant 3: The number of testers who rated the sheet as having good strength and tear resistance was between 25 and 27. 2: 22 to 24 people rated the sheet as strong and tear-resistant 1: 21 or fewer testers rated the sheet as being strong and tear-resistant

[0071] (Seat texture) The feel of the lotion tissue paper sheets (lotion tissue paper) in the produced lotion tissue paper packages was evaluated by 30 monitors. The evaluation criteria are as follows, with 1 point being a failure and 2 points or more being a pass. 4: More than 28 monitors rated the sheet as having an excellent texture. 3: 25 to 27 people rated the sheet as having an excellent texture 2: 22 to 24 people rated the sheet as having an excellent texture 1: Fewer than 21 people rated the sheet as having an excellent texture

[0072] (Ease of portability) The ease of carrying the produced lotion tissue paper packages was evaluated by 30 monitors. The evaluation criteria are as follows, with 1 point being a failure and 2 points or more being a pass. 4: More than 28 testers rated the packaging as being just the right height and easy to carry. 3: Between 25 and 27 testers rated the package height as approximately appropriate and easy to carry. 2: 22 to 24 testers rated the package height as appropriate and easy to carry. 1: Fewer than 21 testers rated the packaging as being roughly the right height and easy to carry.

[0073] (Example 2) to (Example 18), (Comparative Example 1) to (Comparative Example 4) In Examples 2 to 18 and Comparative Examples 1 to 4, packaging substrates having the physical properties shown in Tables 1 to 3 were prepared in the same manner as in Example 1, and lotion tissue paper packages (caramel packaging) were prepared using these in the same manner as in Example 1, and the above-mentioned evaluations were carried out.

[0074] [Table 1]

[0075] [Table 2]

[0076] [Table 3]

[0077] As is clear from the results shown in Tables 1 to 3, the sheets (lotion tissue paper) in the packages of Examples 1 to 18 all had excellent cosmetic properties and texture, were tear-resistant, and were easy to carry. In contrast, the packages of Comparative Examples 1 to 4 were all inferior in any of the cosmetic properties and texture of the lotion tissue paper, ease of tearing, and ease of carrying the package. From the above, it was confirmed that the present invention can provide a lotion tissue paper package that is easy to carry, has good texture and aesthetic appeal of lotion tissue paper, and is difficult to tear, according to this example.
