PROBLEM TO BE SOLVED: To provide a package of toilet rolls with fragrance from added aroma chemicals having high volatility.SOLUTION: In a toilet roll package in which a plurality of toilet rolls with fragrance are packed with a wrapping film, the problem can be solved by the toilet roll package packing the toilet rolls with a wrapping film that has an oxygen permeability of 40 cc/mday atm or less and whose printed area applied on the inside of the film substrate contacting the toilet rolls is covered with a vinyl chloride resin layer.

Description

  The present invention relates to a toilet roll package in which toilet rolls are film-wrapped.

  A plurality of toilet rolls are packaged together with a thin polyethylene film or polypropylene film having a thickness of about 20 to 50 μm and commercialized as a toilet roll package.

  Polyethylene film and polypropylene film are used to wrap toilet rolls in terms of flexibility to fit soft and cylindrical toilet rolls and ease of heat-sealing treatment when forming and sealing bags. Is suitable.

  By the way, in the toilet roll, what gave the fragrance | flavor to the paper itself and a paper tube, and was made fragrant is proposed.

  However, since polyethylene film and polypropylene film are not necessarily high in terms of gas barrier properties, especially when using highly volatile fragrances, they are stored before shipping after commercialization and during storage in the warehouse after shipping. There is a risk that fragrance may leak to the outside during store display.

  On the other hand, on the packaging film for packaging the toilet roll, a product name and a design / pattern for improving design are printed with ink. This printing is performed on the inner surface of the packaging body, that is, the side of the packaging film that comes into contact with the toilet roll, in order to prevent the ink from dropping off due to the sliding of the outer surface of the product that occurs during shipping, delivery, or after carrying the product. It is printed.

  However, a highly volatile perfume component may act as an organic solvent to soften the ink in the printed portion on the inner surface of the packaging film. In particular, in an environment where the temperature is high, for example, in a car in the summer in Japan, the action is promoted, and when the toilet roll and the film are slid, the ink may adhere to the toilet roll.

  Even if the gas barrier property of the packaging film is improved so that a highly volatile fragrance component can be used, the highly volatile fragrance component can easily fill the hermetic package in a high temperature environment. Therefore, the risk of promoting the elution of ink is increased.

  As a technique for preventing the elution of the ink from the packaging film, it is conceivable to use a film substrate whose printing surface has been previously subjected to corona discharge treatment. However, when the corona discharge treatment is performed, the heat-fusibility is remarkably lowered, so that the productivity of the toilet roll package is lowered. Although it is conceivable that only the printed part of the film substrate is subjected to corona discharge treatment, and the part to be heat-sealed is not subjected to corona discharge treatment, but it is very difficult to efficiently perform the corona discharge treatment only on the printed part.

  Although it may be possible to prevent the ink from dropping off in a high-temperature environment by changing the ink to a heat-resistant ink, the heat-resistant ink tends to increase the rigidity after drying, and the expansion and contraction when using the packaging film In contrast, the risk of ink dropping increases. This increases the risk especially in a low temperature environment.

  In this way, in the toilet roll package, from the viewpoint of gas barrier properties of the packaging film and printing of product names, design patterns, patterns, etc., the perfume that imparts fragrance to the toilet roll is limited to those with low volatility. , Increasing variations in “fragrance” and making product discrimination difficult.

  According to the present invention described above, a toilet roll package that does not leak to the outside even when a highly volatile fragrance is used, does not drop off printing, and has excellent heat-fusibility and excellent productivity. Is provided.

It is a perspective view of the toilet roll package of the embodiment of the present invention. It is sectional drawing of the film for toilet roll packaging which concerns on embodiment of this invention. It is sectional drawing of the handle part of the toilet roll packaging body of embodiment of this invention.

  An embodiment of the toilet roll package 1 of the present invention will be described in detail with reference to FIGS. The toilet roll package 1 according to the present embodiment is a group of twelve toilet rolls in which four adjacent toilet rolls 20, 20... Are arranged so that they are in contact with each other on the circumferential surface, and these are stacked in three stages in the end face direction. Is gusset-wrapped with a film 10. However, the number of packaging of the toilet roll 20 in the present invention is not limited to this number. After the toilet roll package 1 is manufactured in the factory, the toilet roll package 1 is distributed to consumers through warehouse storage in the factory, shipping conveyance, storage at the shipping destination warehouse, and store display.

  The toilet roll 20 according to the present embodiment may be either a cored toilet roll in which a belt-shaped toilet paper is wound around a paper tube or a coreless toilet roll called coreless. The size of the toilet roll is not particularly limited. It is common that the height (width) is 100 to 115 mm, the winding diameter (diameter) is 100 to 120 mm, the core diameter is 10 to 48 mm, and the winding length is 20 to 100 m. Can be adopted.

Examples of the toilet paper constituting the toilet roll 20 include one to three plies, a paper thickness of 100 to 180 μm, and a rice basis weight of 11.0 to 25.0 g / m ² per ply. In addition, the rice tsubo here is based on the JIS P 8124 (1998) rice tsubo measurement method, and the paper thickness is adjusted under the conditions of JIS P 8111 (1998) after sufficient humidity control. The average value measured five times using a dial thickness gauge (thickness measuring instrument) “PEACOCK G type” (manufactured by Ozaki Seisakusho).

The toilet roll package 1 according to the present embodiment is characterized in that the packaging film 10 has an oxygen permeability of 40 cc / m ² · day · atm or less, more preferably 20 cc / m ² · day · atm or less, and further In the packaging film 10, a printed portion 10 </ b> B provided on the inner surface side in contact with the toilet roll 20 is covered with a vinyl chloride resin layer 10 </ b> C.

When the oxygen permeability of the packaging film 10 is 40 cc / m ² · day · atm or less, even a highly volatile perfume component is prevented from leaking to the outside. The lower limit value of the oxygen permeability of the packaging film 10 is not particularly limited, but considering that it is a film suitable for toilet roll packaging such as cost, 0.5 cc / m ² · day · atm is a practical lower limit value. It is. The oxygen permeability in the present invention is a value measured under measurement conditions of 23 ° C. and 65% RH based on JIS K 7126 (B).

  In addition, the printing part 10B is provided on the inner surface side that is in contact with the toilet roll 20, thereby preventing ink from dropping off due to sliding of the outer surface of the product that occurs at the time of shipment, delivery or carrying after purchase. Is done. At the same time, the printing portion 10B is covered with the vinyl chloride resin layer 10C, so that the ink constituting the printing portion 10B is prevented from eluting due to the fragrance. Since the vinyl chloride resin has excellent friction resistance and gas barrier properties, it is possible to prevent the ink from being eluted due to the fragrance by covering the printed portion 10B with the vinyl chloride resin layer 10C. . The printed portion 10B is a portion where a product name, product description, and a design pattern / pattern are printed with ink. This printing itself can be provided on the film by a conventionally known ink and printing method.

As shown in FIG. 2, the packaging film 10 according to the present embodiment is a polyethylene film layer having both outermost layers 12 and 13 having a thickness of 8 to 60 μm and a melting point of 80 ° C. or higher and 150 ° C. or lower, between them. A printing portion 10B and a vinyl chloride resin layer 10C are provided for a film substrate 10A having an overall thickness of 17 μm or more and less than 100 μm, in which an ethylene-vinyl alcohol copolymer film layer 11 of 1 to 30 μm is interposed. It is desirable that The polyethylene film layers constituting the outermost layers 12 and 13 have a low melting point and excellent heat-fusibility, and the ethylene-vinyl alcohol copolymer film layer 11 has a very low oxygen permeability, so that the oxygen permeability is 40 cc / m ^2. -Day / atm or less, and heat fusion and flexibility are compatible. In particular, the packaging film 10 has an advantage that gusset packaging can be performed in the same manner as conventional products using a conventionally used gusset packaging apparatus. Further, the oxygen permeability can be preferably 20 cc / m ² · day · atm or less.

  The polyethylene film layers 12 and 13 constituting the film substrate 10 can be fused at a lower temperature when the melting point is lower. However, when the melting point is excessively low, the packaging film 10 is scratched or perforated due to friction or the like. Since a possibility increases, a lower limit is 80 degreeC. Examples of the polyethylene film layers 12 and 13 having a melting point of 80 ° C. or more and 150 ° C. or less include a linear low density polyethylene film layer (LLDPE), a low density polyethylene film layer (LDPE) and a medium density polyethylene film layer (MDPE). In addition, both the outer layers 12 and 13 do not necessarily need to be the same kind of polyethylene film layer.

  On the other hand, the ethylene-vinyl alcohol copolymer film layer 11 (also referred to as an EVOH resin layer) can be formed using a known resin, such as Eval manufactured by Kuraray Co., Ltd. and Nippon Synthetic Chemical. We can present Soarnol from Kogyo Co., Ltd. In particular, when the melting point of the ethylene-vinyl alcohol copolymer film layer is 180 ° C. or less, the heat-fusibility of the entire packaging film 10 is not inhibited. In the tylene-vinyl alcohol copolymer film layer 11, the melting point can be lowered by increasing the ethylene content. However, since the oxygen permeability decreases as the ethylene content increases, the substantial lower limit of the melting point is 150 ° C. from this viewpoint. The ethylene-vinyl chloride copolymer film layer 11 has an ethylene content of 38 mol% or more, preferably 40 mol% or more, particularly preferably 44 mol% or more in order to ensure the melting point and effective oxygen permeability. Is desirable. About an upper limit, since it becomes difficult to ensure oxygen permeability, it is about 50 mol%.

  In addition, in making film base material 10A into the multilayer structure which has a polyethylene film layer and an ethylene-vinyl alcohol copolymer layer, it is made to have another layer in the range which does not impair each layer and those mutual effects. be able to. For example, an appropriate layer used to effectively laminate a laminated film such as an adhesive layer or a cross-linking material layer for integrating the polyethylene film layers 12 and 13 and the ethylene-vinyl alcohol copolymer layer 11. A layer can be provided. Specific examples of the adhesive layer include a maleic anhydride-modified polyolefin layer. When an adhesive layer or the like is provided, the thickness is about 3 to 7 μm, and in this case as well, the thickness of the entire film 10A is desirably 17 to 100 μm so as not to impair flexibility. In addition, confirmation of the film which concerns on this embodiment, and the thickness of each layer can be confirmed by measuring a cross section with an optical microscope.

  Here, the gusset wrapping in the toilet roll wrapping body 1, as understood from FIGS. 1 and 3, the packaging film 10 formed in a cylindrical shape in advance, the inner side of the cylinder so that both side portions thereof are in the shape of a cross section M time. One of the openings is sealed by heat-sealing treatment or the like in a state of being pushed into the bag to form a three-sided closed bag-like precursor, and then the toilet roll 20 as the package is placed in the bag. Then, the other opening is sealed by heat-sealing, and the handle 35 is formed when one or the other opening is sealed. This gusset wrapping has high sealing performance because both end openings are sealed by heat fusion treatment or the like, and is suitable for the package 1 of the scented toilet roll 20, but as shown in cross section in FIG. Since it is necessary to perform heat fusion treatment of the front and back surfaces of the film in a short time at a time in a state where the part is pushed into the cylinder so as to become a cross-section M shape, that is, in a state where at least four layers of the packaging film are stacked, In particular, it is required to have heat transferability in the film thickness direction and excellent heat-fusibility on the front and back of the film. In the illustrated example, the grip portion 35 is formed by laminating a polyethylene film sheet 15 for reinforcement on the packaging film 10, and reference numeral 31 in FIG. Both outermost layers 12 and 13 according to this embodiment are polyethylene film layers having a thickness of 8 to 60 μm and a melting point of 80 ° C. or more and 150 ° C. or less, and an ethylene-vinyl alcohol copolymer film layer 11 of 1 to 30 μm therebetween. Is a film base 10A having an overall thickness of 17 μm or more and less than 100 μm, and the packaging film 10 provided with the printed portion 10B and the vinyl chloride resin layer 10C is a gazette package having such a structure. Can be done as usual. In addition, it is possible to secure moderate flexibility following the shape of the cylindrical toilet roll 20 and strength that can be easily opened by a human hand but not unintentionally broken. That is, it can have high gas barrier properties while having handling properties equivalent to those of a conventional polyethylene film single-layer packaging film. In addition, as for the gusset packaging in the toilet roll package 1, the heat sealing | fusion process is generally performed at 160-250 degreeC. The multi-layered film 10 according to the present embodiment has a structure that is particularly suitable for heat-sealing treatment in this temperature range. In particular, regarding heat fusion in gusset packaging, the heat seal range in JIS K 1707 is desirably 10 N / 15 mm at 110 ° C. or higher under the conditions of a pressure of 0.2 MPa and 1 second. The film 10 having a multilayer structure can be in this range.

  On the other hand, the film base material 10A having a multi-layer structure before providing the printing portion 10B according to the present embodiment can be manufactured by a co-extrusion method by an T-die method or an extrusion laminating method.

  On the other hand, what is necessary is just to provide the printing part 10B of the toilet roll package 1 which concerns on this embodiment with the conventionally well-known ink and printing method with respect to 10 A of film base materials. In the case of the multi-layer structure, since the outermost layers are the polyethylene film layers 12 and 13, if the printing portion is provided by a printing method similar to the printing method performed on the conventional polyethylene film single-layer packaging film, Good.

  Examples of the vinyl chloride resin layer 10C that covers the printed portion 10B include a vinyl chloride layer, a vinylidene chloride layer, and a vinyl chloride synthetic resin layer. This vinyl chloride resin layer 10C can be provided by printing. There is an advantage that it can be easily provided as compared with a resin layer which requires a laminating method or the like. The vinyl chloride resin layer 10C may be printed by dissolving the vinyl chloride resin in an appropriate solvent. The solvent can be appropriately selected according to the specific type of the vinyl chloride resin and the film to be printed. Specific examples of the solvent include aqueous solvents such as water and organic solvents such as cyclohexane, cyclohexanol, toluene, and mixtures thereof. If it is an organic solvent, it is good to print using the solution which melt | dissolved 0.5-50 mass% vinyl chloride resin with respect to the mass of an organic solvent. In particular, when the multi-layer film 10A according to the present embodiment is used, it is desirable to use cyclohexanol that is insoluble in polyethylene and dissolves vinyl chloride. When an aqueous vinyl chloride synthetic resin is used with water as a solvent, it tends to be harder to dry than those using an organic solvent, so it is preferable to provide a drying step after printing to dry the resin. Moreover, when it is difficult to apply uniformly on the film substrate due to the surface tension, a surfactant or the like that lowers the surface tension and does not inhibit the drying of water may be included. In view of handling and ease of printing, it is preferable to use an organic solvent. As for the printing of the vinyl chloride resin, it may be printed on the printing portion 10B and solidly printed by a printing coater, or may be provided by gravure printing. Solid printing by a printing coater that can easily form a vinyl chloride resin layer is preferable. For gravure printing, a suitable gravure plate should have an area ratio of 70% or more and the number of lines of 50 or less. Printing may be overprinted twice or more. You may make it perform formation of a printing part and formation of a vinyl chloride-type resin layer using a multicolor printing apparatus.

  On the other hand, the packaging film 10 according to the present embodiment can have a tensile strength in JIS Z 1707 of 20 to 60 MPa in the MD direction, preferably 25 to 35 MPa, and 20 to 60 MPa in the TD direction, preferably 25 to 35 MPa. The packaging film 10 according to this embodiment has an elongation in JIS Z 1707 of 150 to 400%, preferably 160 to 350% in the MD direction, and 150 to 800%, preferably 400 to 700% in the TD direction. It can be. Within these tensile strength and elongation ranges, moderate flexibility following the toilet roll 20, ease of portability when made into gusset packaging, operation of tearing the packaging film as intended during use, etc. are effectively exhibited. It will be a thing. The tensile strength and elongation are measured at a tensile speed of 500 mm / min. Furthermore, the packaging film 10 according to the present embodiment is not particularly limited as a result of the tear test (Elmendorf method) according to JIS K 7128, but it may be about 100 to 800 N / cm in both the MD direction and the CD direction. .

  On the other hand, the toilet roll 20 which concerns on this embodiment is a toilet roll with a fragrance | flavor to which the fragrance | flavor was provided. Examples of the position where the fragrance is attached include front and back surfaces of toilet paper, paper tubes, and end surfaces of toilet rolls. If the paper tube has a core with a fragrance attached to the paper tube, the fragrance will not adhere to the skin when the toilet paper is used. This is desirable because it will give off a fragrance for a long time in the toilet until it is used up. Furthermore, if it is applied to the paper tube, if there is a fragrance on the inner surface of the paper tube that is not in direct contact with the film, the effect on the printing ink is small.

  As the fragrance, a natural or synthetic fragrance can be used. Specific examples include natural perfumes such as lemon oil, grapefruit oil, rosemary oil, peppermint oil, mandarin oil, lime oil, yuzu oil, chamomile oil, lavender oil, rose oil, spearmint oil; linalool, citronellol, menthol, Synthetic fragrances such as alcohols such as geraniol. These may be used as individual fragrances, or may be used as combined fragrances by combining a plurality of fragrance components. The selection of the fragrance or the fragrance component may be determined according to the desired fragrance. In addition, a fragrance | flavor can be diluted using vegetable oils, such as mineral oil, such as dipropylene glycol and paraffin oil, castor oil, and soybean oil, in order to adjust the intensity | strength of a fragrance | flavor and volatility.

In particular, the packaging film 10 according to this embodiment has an oxygen permeability of 40 cc / m ² · day · atm or less, and the oxygen permeability is orders of magnitude lower than conventional packaging films made of polyethylene film or polypropylene film. In addition, the problem of ink elution in the printed portion 10B has been solved, and a highly volatile perfume component that has been difficult to use can be used. In perfume products, the fragrance that is called the top note is highly volatile and strongly felt in the early days, the fragrance that is called the bottom note that becomes low and gradually felt, and these that are called the middle note. The intermediate fragrance is appropriately mixed to compose a complex fragrance or a change in fragrance over time. In scented toilet rolls, the oxygen permeability of wrapping films has been high so far, especially in the scent of the top notes, and many people feel fresh or refreshing. It was difficult to make an incense tone. The toilet roll package 1 according to the present embodiment is a perfume component according to the top note, in terms of numerical values, even if a perfume component having a vapor pressure of 50 Pa or higher in an environment of a temperature of 20 ° C. and a humidity of 50% RH is used. Incense tone by the fragrance component becomes possible, and the variation of “fragrance” of the toilet roll product with fragrance can be increased.

  As described above in detail, the toilet roll package 10 according to the present embodiment is a toilet roll 20 to which a highly volatile fragrance is applied, and the fragrance does not leak to the outside, and the printed portion caused by the fragrance There is no risk of ink elution, so that the variation of “scent” in the toilet roll can be increased, and gusset packaging can be achieved as in the case of conventional products, and productivity is not lowered.

  Next, Examples and Comparative Examples of the present invention were tested for heat-fusibility, ink dropout, and fragrance persistence. Each example, test and evaluation are as follows, and the results of the test are as shown in Table 1 below.

(Example 1) An overall thickness of an ethylene-vinyl alcohol copolymer film layer (EVOH) having a thickness of 3 μm interposed between a polyethylene film layer (PE layer) having a thickness of 16 μm and a melting point of 120 ° C. After design printing was performed on a 35 μm film substrate, a toilet roll package was formed with a packaging film in which the printed portion was covered with a vinyl chloride resin layer. The vinyl chloride resin layer was formed by solid printing a solution in which 5% by mass of a vinyl chloride resin of the solvent was dissolved using cyclohexanol as a solvent. The oxygen permeability was 3.3 cc / m ² · day · atm.

(Example 2) An overall thickness in which an ethylene-vinyl alcohol copolymer film layer (EVOH) having a thickness of 0.7 μm was interposed between a polyethylene film layer (PE) having a thickness of 16 μm and a melting point of 120 ° C. Was subjected to design printing on a 32.7 μm film substrate, and then a toilet roll package was formed with a packaging film in which the printed portion was coated with a vinyl chloride resin layer. The vinyl chloride resin layer was formed by solid printing a solution in which 5% by mass of a vinyl chloride resin of the solvent was dissolved using cyclohexanol as a solvent. The oxygen permeability was 39 cc / m ² · day · atm.

(Comparative Example 1) A toilet roll package was formed using a packaging film designed and printed with a conventional ink on a film of a polyethylene film single layer (PE) having a thickness of 50 μm. The oxygen permeability was 3300 cc / m ² · day · atm.

(Comparative Example 2) A toilet roll package was formed using a packaging film that was designed and printed with heat-resistant ink on a 48 μm thick polyethylene film single layer (PE) film and no vinyl chloride resin layer was formed. The oxygen permeability was 3200 cc / m ² · day · atm.

(Comparative Example 3) A packaging film in which one side of a 47 μm-thick polyethylene film (PE) film is subjected to corona discharge treatment, and design printing is performed on the treated surface with conventional ink to form no vinyl chloride resin layer. Used to form a toilet roll package. The oxygen permeability was 3150 cc / m ² · day · atm.

(Comparative Example 4) Packaging in which one side of a 47 μm-thick polyethylene terephthalate film (PET) film is subjected to corona discharge treatment, and design printing is performed on the treated surface with conventional ink to form a vinyl chloride resin layer. A toilet roll package was formed using the film. The oxygen permeability was 3150 cc / m ² · day · atm.

(Test method and evaluation)
The heat-fusibility was performed by carrying out gusset packaging in the form shown in FIG. 1 and confirming whether each necessary part was heat-sealed and sealed. Evaluation is necessary if it can be confirmed that the necessary parts have been fused and gusseted without any problems. Necessary parts have been fused once. The case where there were unfused parts in each part was evaluated as x.

  The ink is removed when the toilet roll to be packaged is added with a fragrance to the paper tube. When the ink is left to stand for 480 minutes in a high temperature environment (70 ° C.) and 480 minutes in a low temperature environment (−5 ° C.), It was visually confirmed whether there was any elution or separation. The evaluation was evaluated as ○ when the ink was not removed, and × when it was recognized. In addition, the synthetic fragrance | flavor of the composition of 22 mass% of alcohols, 14 mass% of aldehydes, 39 mass% of esters, 7 mass% of lactones, 13 mass% of synthetic musks, and 5 mass% of other fragrance | flavors was used.

  The durability of the scent is determined by sealing the toilet roll with scent used in the ink drop-off test using the film according to each example, and leaving it in an environment of 50 ° C. and 50% RH for 2 days. It was confirmed whether the toilet roll scent was maintained. The evaluation was evaluated as ○ when the fragrance was generally maintained, △ when the fragrance was slightly felt, and × when the fragrance was significantly decreased.

  As can be understood from the results in Table 1, both Examples 1 and 2 of the present invention can be gusseted without problems. It was also recognized that the toilet roll scent was sufficiently durable and the scent did not leak out. Furthermore, in Example 1 and Example 2, it is recognized that the fragrance does not leak to the outside based on the result of the scent sustainability test, and the package is in an environment where the fragrance is volatilized and filled. Even under such circumstances, no ink dropout was observed in either a low temperature environment or a high temperature environment.

  On the other hand, Comparative Example 1 was able to perform gusset packaging without any problem, but ink was eluted in a high temperature environment. There was also a problem with the maintenance of fragrance.

  In Comparative Example 2, the gusset packaging could be performed without any problem, but a phenomenon that a part of the ink was detached from the film substrate in a low temperature environment was confirmed.

  In Comparative Example 3, there was a part that was not completely heat-sealed, and gusset packaging could not be performed without any problem.

  Similarly, in Comparative Example 4, there was a part where heat fusion was not completely completed, and gusset packaging could not be performed without any problem. Moreover, although the sustainability of the scent of the toilet roll was good as compared with Comparative Examples 1 to 3, it was insufficient.

  As is clear from the results of the above tests, the toilet roll package according to the present invention does not leak fragrance to the outside even when a highly volatile fragrance is used. It was confirmed that this was a toilet roll package having excellent properties and manufacturability.
