Description

cigarette

The present invention relates to a cigarette provided with a cigarette filter including a fragrance capsule.

Conventionally, a fragrance capsule is incorporated into a cigarette filter, the fragrance capsule is crushed during use, the scent of the content liquid is enjoyed during smoking, and the smell of the butts after digestion is masked (Patent Document) 1 and 2). The details of the fragrance capsule are described in Patent Document 3, for example.

Chipping paper and plug web are generally blindfolded so that the joint between the filter and the tobacco rod is not visible, and the color of tar adhering to the filter media due to smoking is hidden. Opaque paper is used. In addition, in the case of a charcoal filter, opaque chipping paper and plug winding paper have the role of making the color of activated carbon invisible in addition to the above-mentioned role.

On the other hand, the inside of the filter is visualized using a transparent chipping paper or a transparent plug web (Patent Documents 4 to 6).

Patent Document 4 discloses that a transparent material is used as a chipping paper or a plug winding paper in order to visualize the inside of a filter, and that a blind coating function is imparted by applying an opaque coating to a part of the chipping paper. Patent Document 4 exemplifies polypropylene, polyvinyl chloride, cellulose acetate film, polyethylene terephthalate, polyethylene oxide, polyethylene, cellophane, Natureflex (registered trademark) and polyacetic acid as transparent materials. Patent Document 4 discloses that the chipping paper and the plug web may be translucent by coloring in order to provide an aesthetic effect to the filter as long as the inside of the filter can be visualized.

Patent Document 5 discloses the use of a transparent film material so that the perfume particles in the filter can be visually observed as chip paper or filter wrapping paper, and examples of the transparent film material include polypropylene, polyvinyl chloride, and cellulose acetate film. .

Patent Document 6 discloses the use of a transparent material as a chipping paper or a plug winding paper in order to visualize the extraction effect of harmful substances.

Japanese Patent Laid-Open No. 7-250665 Special table 2007-520204 Special table 2008-546400 gazette International Publication No. 2009/106374 Pamphlet No. 5-45198 International Publication No. 2004/068975

When the cigarette which contains a fragrance capsule in a filter part is wound with opaque plug winding paper or opaque chip paper, when a smoker crushes a fragrance capsule, the problem that the position of a fragrance capsule is difficult to understand. It was noticed that there was a problem that the capsule content liquid was not developed in the filter after crushing the capsule.

When using transparent tip paper or transparent plug web to visualize the perfume capsules in the filter, the above-mentioned blindfold function (i.e., the filter and cigarette rod joints cannot be seen or the filter media of the filter is covered). The function of hiding the color of the attached tar) is impaired. In addition, when the fragrance capsule was visualized using transparent chip paper or transparent plug winding paper, even though capsule destruction could be recognized, the capsule content liquid was very small, so it fully developed in the hollow part. It is difficult to recognize this visually.

Therefore, the present invention provides
(A) Chip paper and plug web retain blind function,
(B) When a smoker crushes the fragrance capsule in the filter, the position of the capsule can be visually recognized through the chip paper and the plug web, and (c) the chip paper and the plug web after crushing the capsule. An object of the present invention is to provide a cigarette provided with a chip paper and a plug web so that the capsule content liquid can be visually recognized through the filter.

Until now, cigarettes containing fragrance capsules are intended to prevent capsule contents liquid released by capsule destruction from causing blotting on the plug web or chip paper, for example, when using a lipophilic solvent as the capsule contents liquid, Oil resistant paper is preferably used as the plug web. Contrary to this, the present inventors have completed the present invention by causing the capsule content liquid to adhere to the translucent plug web and generating a blot with higher transparency on the plug web.

That is, according to the present invention,
A tobacco rod including a tobacco filler and a tobacco wrapping paper wrapped around the tobacco filler;
A tobacco rod including a tobacco filler and a tobacco wrapping paper wrapped around the tobacco filler;
A plurality of filter plugs spaced apart from each other, a plug web wound around the filter plug so as to form a hollow portion between the filter plugs, a fragrance located in the hollow portion, and a fragrance in the film A filter comprising a perfume capsule holding a content liquid containing;
Including the tobacco rod and chip paper wound on the filter so as to connect the tobacco rod and the filter;
The plug web is impermeable to the liquid content;
The opacity of the laminated paper composed of the plug web and the chip paper is (i) 70% or less before the break of the fragrance capsule, and (ii) the content liquid released by the break of the fragrance capsule is applied to the plug roll paper. A cigarette is provided that is reduced by 5% or more when adhered.

According to the cigarette of the present invention,
(A) Chip paper and plug web retain the function of blindfold,
(B) The smoker can visually recognize the position of the capsule through the tip paper and the plug web when crushing the fragrance capsule in the filter, and (c) After crushing the capsule, plug it with the capsule content liquid. It is possible to visually recognize that the capsule content liquid has spread in the filter by causing a stain on the web.

Sectional drawing which shows a part of cigarette of this invention after crushing a fragrance | flavor capsule. Explanatory drawing which shows the filter of the Example of this invention. Explanatory drawing which shows the cigarette of the Example of this invention.

Hereinafter, the present invention will be described with reference to the drawings. However, the following description is intended to explain the present invention in detail and is not intended to limit the present invention.

1A and 1B are cross-sectional views showing a part of the cigarette of the present invention. FIG. 1A shows the cigarette before the fragrance capsule 23 is crushed, and FIG. 1B shows the cigarette after the fragrance capsule 23 is crushed.

1A and 1B includes a cigarette rod 10 and a filter 20 in which a fragrance capsule 23 is accommodated in a hollow portion formed by two

filter plugs

21a and 21b and a plug web 22, and the cigarette rod 10 and the filter. 20 are connected by a chip paper 30. The cigarette shown to FIG. 1A and 1B has a column shape as a whole like the normal cigarette with a filter.

The tobacco rod 10 is composed of the tobacco filler 11 and the tobacco paper 12 wound around the cigarette filler 11 like a normal cigarette, and can have a diameter of 5 to 10 mm and a length of 40 to 80 mm, for example.

The filter 20 includes two

filter plugs

21a and 21b that are spaced apart from each other via a hollow portion, and a plug web 22 wound around the filter plug so as to form a hollow portion between the

filter plugs

21a and 21b. And a fragrance capsule 23 which is contained in a hollow portion between the filter plugs and holds a liquid containing the fragrance in the film. The filter 20 has approximately the same diameter as the tobacco rod 10, and the length can be, for example, 15 to 40 mm, as in a normal filter.

In the cigarettes of FIGS. 1A and 1B, two

filter plugs

21a and 21b are arranged through one hollow portion, but there are (n−1) filter plugs of n (n is an integer of 2 or more). For example, n is 2 to 4, preferably n is 2 to 3, and more preferably n is 2.

The

filter plugs

21a and 21b can be made of a fibrous filter material such as cellulose acetate fiber as in the case of a normal cigarette with a filter. The filter plug may be composed only of a fibrous filter material, or may be composed of a fibrous filter material and material paper wound around it. The filter plug 21a on the cut side and the filter plug 21b on the suction side may have the same material and structure, or may have different materials and structures.

The plug web 22 is wound around the two filter plugs 21, and as a result, forms a hollow portion together with the two

filter plugs

21a and 21b. The plug web 22 is translucent and has an opacity level such that the fragrance capsule 23 located in the hollow portion can be visually recognized. That is, the plug web 22 has such an opacity that a smoker can visually recognize the position of the fragrance capsule when the fragrance capsule in the filter is crushed. For this reason, the plug web 22 also has a blinding function for hiding the internal structure of the filter. Moreover, if the capsule content liquid discharged | emitted by destruction of the fragrance | flavor capsule adheres, the opacity will fall and the visual recognition level of a fragrance | flavor capsule will increase. That is, the plug web 22 is more transparent at the position where the capsule content liquid adheres, and the outline of the broken fragrance capsule can be clearly seen. “Visibility level increases” means that the outline of the broken fragrance capsule becomes clearly visible, specifically, the evaluation score increases according to the evaluation criteria described in Table 1 described later. . Thereby, the smoker can visually recognize that the capsule content liquid has developed in the hollow portion.

As described above, in the present invention, the capsule content liquid is attached to the translucent plug web, and a blot having higher transparency is generated in the plug web, and the spread of the stain causes the capsule content liquid to expand in the hollow portion. Can be recognized visually. Thereby, the smoker can enjoy the scent after confirming that the capsule content liquid has sufficiently developed in the hollow portion.

In order to achieve the above-described effects, the plug web 22 in the present invention specifically has the following three requirements.

(1) The plug web is impermeable to the capsule content liquid.

(2) Laminated paper composed of plug winding paper and chip paper has an opacity of 70% or less.

(3) The laminated paper composed of the plug winding paper and the chip paper has an opacity of 5% or more lower than that before the capsule destruction when the capsule content liquid released by the destruction of the fragrance capsule adheres.

In the present invention, the chip paper is preferably transparent. When the chip paper is transparent, the opacity is generally 0.5 to 3%. As transparent chip paper, for example, NatureFlex 23μ (Innovia) and NatureFlex 42μ (Innovia) can be used as a base film for chip paper. For this reason, when the chip paper is transparent, the chip paper does not substantially affect the opacity of the laminated paper. Therefore, when the chip paper is transparent, the requirement of (2) is expressed as “the plug web has an opacity of 70% or less”, and the requirement of (3) is “the plug web is of the fragrance capsule. When the capsule content liquid released by destruction adheres, it has an opacity of 5% or more lower than before capsule destruction.

Throughout this specification, opacity refers to a value measured according to JIS P8138A (1976).

Specifically, whether or not the plug web meets the requirement (1) can be determined as follows. That is,
Stack the plug web and test paper to form a laminated paper, measure the opacity of the laminated paper from the side of the test paper,
Drop capsule content liquid from the side of the plug web, measure the opacity of the laminated paper from the side of the test paper,
Find the difference in opacity by subtracting the opacity after dropping the capsule content liquid from the opacity before dropping the capsule contents liquid,
When the difference is 10% or less, the plug web is evaluated as impermeable to the capsule content liquid, and when the difference exceeds 10%, the plug web is against the capsule content liquid. Evaluated as not impervious (see Example 2 below). Therefore, in the present invention, “having impermeability” includes not only complete impermeability but also impervious but very slight permeability (see Table 3 below). reference). The measurement of opacity here is also performed according to JIS P8138A (1976). The “test paper” used herein is an opaque paper having a function as a filter paper that can absorb the liquid when the liquid permeates the plug web, and has a thickness 33 with an opacity of 80 or more, for example. Paper having a thickness of 53 μm can be used, and 37 white base paper (Nippon Paper Papillia Co., Ltd.) can be mentioned as an example.

Specifically, whether or not the laminated paper composed of the plug winding paper and the chip paper satisfies the requirement (2) can be determined as follows. That is, a plug paper and chip paper are overlapped to form a laminated paper, and the opacity of the laminated paper is measured from the chip paper side (see Example 3 described later). The measurement of opacity here is also performed according to JIS P8138A (1976). In the present invention, the opacity thus measured (that is, the opacity before the capsule content liquid adheres) is 70% or less, preferably 5 to 70%, more preferably 10 to 40%, More preferably, it is 15 to 40%. When the opacity exceeds 70%, it is difficult to visually recognize the fragrance capsule through the plug web and the chip paper.

Specifically, whether or not the laminated paper composed of the plug winding paper and the chip paper satisfies the requirement (3) can be determined as follows. That is,
Stack the plug roll paper and chip paper to form a laminated paper, measure the opacity of the laminated paper from the chip paper side,
Drop the capsule content liquid from the side of the plug web, measure the opacity of the laminated paper from the side of the chip paper,
The difference in opacity is obtained by subtracting the opacity after dropping the capsule content liquid from the opacity before dropping the capsule content liquid (see Example 3 described later). The measurement of opacity here is also performed according to JIS P8138A (1976). In the present invention, the difference in opacity thus determined is 5% or more, preferably 5 to 30%, more preferably 10 to 30%. When the difference in opacity is less than 5%, the decrease in opacity of the laminated paper is not sufficient, and it is difficult to recognize that the capsule content liquid released by the capsule breakage has spread into the filter hollow portion. .

Regarding the requirements of (2) and (3), before manufacturing the cigarette, the opacity of the laminated paper formed by stacking the plug web and the chip paper may be measured, or after manufacturing the cigarette, The laminated paper in which the plug web and the chip paper are bonded may be cut out from the position of the hollow portion, and the opacity of the laminated paper may be measured. In the latter case, the laminated paper contains an adhesive, but a transparent adhesive (such as an emulsion-based adhesive) is generally used to bond the plug web and the chip paper, so the effect of the adhesive on opacity Can be ignored.

More specifically, as the plug web 22, paper having an opacity of 5 to 40%, a smoothness of 500 to 2500 seconds, and an ash content of 0 to 5% can be used. Preferably, the plug web 22 can be paper having an opacity of 20-40%, a smoothness of 500-2500 sec, and an ash content of 0-5%. More specifically, the plug web 22 can be glassine paper or parchment paper that satisfies the above conditions. Preferably, the plug web 22 can be glassine paper that satisfies the above conditions. When the opacity exceeds 30%, it is not preferable from the viewpoint of visual recognition of the fragrance capsule. Further, if the smoothness is less than 500 sec, it is not preferable from the viewpoint of impermeability to the capsule content liquid. Further, if the ash content exceeds 5%, it is not preferable from the viewpoint of increasing opacity. The plug web 22 can be, for example, 40-80 μm thick.

The plug web 22 is provided with an area of a specific shape having water repellency or oil repellency on the inner surface (surface on the hollow portion side), so that when the content liquid released by the destruction of the perfume capsule adheres, The specific shape may be processed so as to emerge. The region having water repellency can be formed by applying paraffin, silicon or the like, and the region having oil repellency can be formed by applying wax, paraffin, carboxymethylcellulose, latex or the like. These materials can be applied by coating on the plug web using printing techniques. The specific shape may be any shape such as a symbol; a figure such as a circle, a triangle, a square, or a star; a letter such as an alphabet.

In the cigarette of FIGS. 1A and 1B, the fragrance capsule 23 is accommodated in a hollow portion between the filter plugs. One perfume capsule may be accommodated per hollow part, or a plurality of (for example, 2 to 10) perfume capsules may be accommodated.

The fragrance capsule is composed of a film 23a and a content liquid 23b containing the fragrance. For the film 23a, for example, starch, dextrin, polysaccharides, agar, gellan gum, gelatin, various natural gelling agents, glycerin, and the like can be used, and a flavor and a coloring agent can be further included. The fragrance capsule is preferably colored so that a smoker can recognize it when crushing the fragrance capsule even when surrounded by plug winding paper having opacity, and the film 23a contains a colorant such as Blue No. 1 It is preferable. As a fragrance | flavor of the content liquid 23b, a menthol, a vegetable essential oil, etc. can be used, for example. As the solvent of the content liquid 23b, a solvent suitable for a fragrance can be used, and medium chain fatty acid triglyceride (MCT) (specifically, tricapryl / glyceryl caprate), propylene glycol, water, ethanol, etc. can be used. it can. The content liquid may further contain other additives such as other solvents, pigments, emulsifiers and thickeners.

The method for producing the fragrance capsule is not particularly limited. For example, if a dropping method is used, a fragrance capsule having a seamless film can be produced. In this method, by using a double nozzle and simultaneously discharging the content liquid from the inner nozzle and the liquid film material from the outer nozzle, the film liquid can wrap the content liquid without having a seam. The perfume capsule can have a diameter of 1.5 to 7.0 mm, for example.

When producing the cigarette of the present invention, the fragrance to be contained in the cigarette is first determined, and a solvent suitable for dissolving the fragrance is selected according to the type of the fragrance. A plug web that satisfies the requirements of 1) to (3) can be selected. For example, when menthol is contained in cigarette, medium-chain fatty acid triglyceride is selected as a solvent, and paper satisfying the above requirements (1) to (3), such as 40.0 extra-thick white glassine (Nippon Paper Papillia Co., Ltd.) Company; glassine paper), 25.8 thin white glassine (Nippon Paper Papillia Co., Ltd .; glassine paper), drape W34.9 (Oji Special Paper Co., Ltd .; parchment paper), JT highly transparent glassine 40 (Nippon Paper Papillia Co., Ltd .; glassine paper) ) And the like can be selected (see Tables 4 and 6).

In the cigarettes of FIGS. 1A and 1B, the chip paper 30 is preferably impermeable to the content liquid. The chip paper is preferably transparent. Transparent cellophane can be used as such chip paper.

The chip paper 30 is bonded with an adhesive so as to cover the entire plug web 22 and a part of the cigarette paper 12. The adhesive is preferably colorless and transparent so as not to affect the visual recognition level of the perfume capsule. For example, an emulsion adhesive can be used. For example, the tip paper 30 may have a length (width) in the axial direction of the tobacco rod of 20 to 50 mm and a thickness of 10 to 100 μm. Similar to a normal cigarette with a filter, chip paper may be provided with a large number of small openings (ventilation holes) for ventilation in a single row, a plurality of rows, or irregularly along the circumferential direction of the cigarette. The chip paper 30 may be coated on a region other than the hollow portion, for example, printed on a white background.

Example 1 Capsule Visibility In this example, it was evaluated whether or not the perfume capsules could be visually recognized before and after crushing the cigarette perfume capsules of the present invention.

2. 2. Manufacture of filter The filter shown in FIG. 2 was manufactured using the above plug web. The filter is composed of a filter plug 21 a on the cut side (left side), a filter plug 21 b on the suction side (right side), a plug web 22, and a fragrance capsule 23.

"The engraved filter plug 21a" is made of non-Wrap-Acetate (ATK2010-02) ろ filter material (not including material paper), and its length L1 is 11 mm and the circumference is 24.1 mm. The “suction side filter plug 21b” is composed of Acetate tow (2.8Y35000) filter material and P10000C material paper, and its length L2 is 10 mm and circumference is 24.1 mm. The length (S) of the hollow portion formed from these two filter plugs and the plug web is 6 mm. The fragrance capsule 23 is composed of a content liquid 23b containing a medium-chain fatty acid triglyceride (tricapril / glycerine caprate) and a fragrance (menthol and plant essential oil) and a film 23a based on a polysaccharide (starch). The diameter D is 4.5 mm. The perfume capsule was prepared by mixing starch (20% by weight) as a film substance and the content liquid (80% by weight), and dropping the mixture. The total length (Lf) of the manufactured filter is 27 mm.

Two filter plugs and a fragrance capsule were wound on a plug roll paper 22 as shown in FIG. 2 by using an FLR hoist (ND-5RC, Mitsui Machinery Co., Ltd.).

3. Cigarette production The cigarette shown in FIG. 3 was produced using the filter produced as described above. The cigarette is composed of “tobacco rod 10”, “filter 20”, and “chip paper 30”.

“Tobacco rods” were manufactured and sold by Mild Seven tobacco rods. The tobacco rod has a length (Lr) of 57 mm and a circumference of 24.8 mm. The “filter” is as shown in FIG. 2, and its total length (Lf) is 27 mm. “Chip paper” used NatureFlex 23μ (Innovia) as a base film, and TANNPAPIER GmbH printed 10 mm on both sides of the chip paper on a white background and processed into chip paper. The length (Lt) of the chip paper is 32 mm, and the length of the white portion (Lt1 and Lt2) is 10 mm.

EVA-based emulsion was used as the chip paste. Cigarettes A and B were prepared from the filters A and B using a cigarette hoist (HAUNI Protos M5). In addition, cigarettes C to G were created from the filters C to G by hand winding.

4). Evaluation result The visibility (visibility level) of the fragrance capsule was visually evaluated. Evaluation was carried out under a standard light source at 23 ° C., 50% humidity.

(1) Two cigarettes A to G were prepared.

(2) About one of the two, the capsule was crushed with radio pliers.

(3) A cigarette with a crushed capsule was placed on a desk and left for 5 minutes.

(4) The left cigarette was placed on a commercially available copy paper, and the visibility of the capsule was visually evaluated.

The scoring was based on the following table.

(5) Cigarettes before crushing were evaluated in the same manner. The difference between this evaluation score and the evaluation score obtained in (4) was calculated as “change in visibility”.

(6) Evaluation is performed by five evaluators, and the visual evaluation results are shown below. The following table shows the visual evaluation results together with the opacity measurement results. As the measurement result of opacity, the result obtained in Example 3 (Table 6) described later is transcribed.

In Cigarette C, the capsule cannot be visually recognized before crushing, and 50NFB (oil resistant paper) is not suitable as a plug web. In Cigarette F, the capsule can be clearly visually recognized before and after crushing, and NatureFlex® 42μ does not have a blindfold function and is not suitable as a plug web. On the other hand, in cigarettes A, B, D, E, and G, the capsule can be visually recognized before being crushed (evaluation points 2 to 3), and when the capsule is crushed, the liquid in the capsule adheres to the plug web. The capsule can be recognized more clearly and visually.

Opacity 15-25%, smoothness 1500sec or more, ash content 0-5%
2. Evaluation method Medium chain fatty acid triglyceride (MCT) (tricapryl / glycerine caprate), propylene glycol (PG), and water were used as the additive liquid.

Evaluation was carried out at 23 ° C, humidity 50%, and standard light source.

(1) Before dripping the liquid, the plug web is superimposed on chip paper (37 white base paper; Nippon Paper Papillia Co., Ltd.) (test paper). Measured according to JIS P 8138A).

(2) After dropping the liquid 70 μl of the liquid was dropped on the plug web of the above laminated paper. Two minutes after dropping the liquid, the liquid remaining on the surface of the plug web was wiped off. Thereafter, the opacity (%) was measured from the chip paper side by the Hunter method (JIS P 8138A).

The difference between the opacity (%) after dropping the liquid and the opacity (%) before dropping the liquid was calculated as “amount of change in opacity”. The imperviousness was evaluated as shown in the following table based on “amount of change in opacity”.

When the liquid was water, it was dried over time, so the opacity could not be measured, and the impermeability was instantaneously evaluated according to the evaluation criteria shown in Table 3.

3. Evaluation Results The “variation in opacity” and “evaluation of impermeability” are shown below for various plug webs.

Plain paper 24, N250, NPWS, P10000C, and P20000C are permeable to any liquid and are not suitable for use as a plug web. NatureFlex 23μ, 50NFB, drape W34.9, graphane, and highly transparent glassine 40 were impervious to any liquid. Glassine 25.8 showed some permeability to medium chain fatty acid triglycerides, but seems to have no problems for use as a plug web. Since Glassine 25.8 was permeable to water, water cannot be used as a solvent for perfume capsules. Glassine 40 was impervious to all liquids except water.

Example 3 Change in Opacity of Plug Wrapping Paper Evaluation Method In this example, the plug web used in Example 2 was overlapped with the transparent chip paper NatureFlex 23μ, and the change in opacity due to the adhesion of liquid was evaluated. The same liquid used in Example 2 was dropped, and evaluation was performed in the same manner as in Example 2.

The difference between the opacity (%) after dropping the liquid and the opacity (%) before dropping the liquid was calculated as “amount of change in opacity”. “Amount of change in opacity” was evaluated in relation to “appearance (transparency)” as shown in the table below.

As shown in Table 5, when the amount of change in opacity is 5% or more, it can be visually recognized that the transparency has increased.

2. Evaluation Results The “variation in opacity” and “evaluation” for various plug webs are shown below.

The plain paper 24, N250, NPWS, P10000C, and P20000C had a large change in opacity after dropping any liquid, but the results of Example 2 show permeability to any liquid. Not suitable as a plug web.

NatureFlex 23μ does not show an opacity change of 5% or more, so it is not suitable as a plug web.

Since 50NFB is opaque, when this paper is used, the position of the fragrance capsule cannot be recognized, so it is not suitable as a plug web.

Drape W34.9 had an opacity of 37.2% before dripping, and showed an opacity change of 5% or more after dripping of any liquid, and increased transparency. I was able to recognize it visually. Further, the drape W34.9 was impermeable to any liquid (see the results of Example 2). Therefore, the drape W34.9 can be used as a plug web.

¡Graphan does not show a change in opacity of 5% or more, so it is not suitable as a plug web.

Glassine 25.8 has an opacity before dropping of 20.9%, and shows a change in opacity of 5% or more after dropping of medium-chain fatty acid triglyceride (MCT) and propylene glycol (PG). It was possible to visually recognize that the increase was. Glassine 25.8 was impervious to medium chain fatty acid triglycerides (MCT) and propylene glycol (PG) (see results in Example 2). From this, glassine 25.8 can be used as a plug web when these liquids are used as a fragrance-containing liquid.

Glassine 40 has an opacity of 31.2% before dropping, and exhibits an opacity change of 5% or more after dropping of medium chain fatty acid triglyceride (MCT), propylene glycol (PG) and water, and is transparent. It was possible to visually recognize that the increase was. Glassine 40 was impervious to medium chain fatty acid triglycerides (MCT), propylene glycol (PG) and water (see results in Example 2). From this, glassine 40 can be used as a plug web when these liquids are used as a fragrance-containing liquid.

Highly transparent glassine 40 had an opacity of 16.2% before dropping, and showed a change in opacity of 5% or more after dropping of medium chain fatty acid triglyceride (MCT). I was able to recognize it. In addition, the highly transparent glassine 40 was impermeable to any liquid (see the results of Example 2). Therefore, the highly transparent glassine 40 can be used as a plug web.
