Description

Packaging material for nicotine pouch, nicotine pouch including same, and method for manufacturing same

[0001] The present invention relates to a packaging material for a nicotine pouch, a nicotine pouch including the same, and a method for manufacturing the same.

[0002] Nicotine pouches are a type of smoking device used in the mouth to provide nicotine gratification. For example, nicotine pouches can be used by placing the pouch between the upper or lower gums and the lips and holding it there for a limited period of time.

[0003] A nicotine pouch consists of a nicotine pouch filler packaged within a packaging material. The packaging material holds the nicotine pouch filler in place, allowing saliva to pass through the filler, and the flavor and nicotine released from the nicotine pouch filler diffuse into the user's mouth.

[0004] At this time, the packaging material for the nicotine pouch must not burst during the manufacturing and distribution process, and must provide a positive tactile sensation to the smoker during oral use, while preventing the nicotine pouch filler from leaking out.

[0005] Meanwhile, spunlacing, a nonwoven fabric manufacturing method, is primarily used to manufacture packaging materials for nicotine pouches. Spunlacing involves forming a sheet-like web of a certain thickness using a clumped fiber material, spraying moisture to entangle the fibers, forming the material, and then drying it. However, nicotine pouch packaging materials manufactured using spunlacing suffer from uneven airtightness.

[0006] The purpose of the present invention is to provide a packaging material for a nicotine pouch that has a uniform airtightness, has a strength that prevents the nicotine pouch from bursting, and can provide a soft feel.

[0038] In addition, when describing with reference to the attached drawings, identical components will be assigned the same reference numerals regardless of the drawing numbers, and redundant descriptions thereof will be omitted. When describing embodiments, if a detailed description of a related known technology is judged to unnecessarily obscure the gist of the embodiment, the detailed description will be omitted.

[0039] Additionally, in describing components of an embodiment, terms such as first, second, A, B, (a), (b), etc. may be used. These terms are only intended to distinguish the components from other components, and the nature, order, or sequence of the components are not limited by the terms.

[0040] Components included in one embodiment and components with common functions will be described using the same names in other embodiments. Unless otherwise stated, the descriptions given in one embodiment can be applied to other embodiments, and detailed descriptions will be omitted to the extent of overlap.

[0041] Throughout the specification, when a part is said to "include" a component, this does not mean that it excludes other components, but rather that it may include other components.

[0042]

[0043] According to one embodiment of the present invention, a nicotine pouch packaging material can be provided, which comprises cellulose fibers; and thermoplastic material fibers; wherein the content of the cellulose fibers is 40 to 80 wt% based on the total weight of the nicotine pouch packaging material, and the content of the thermoplastic material fibers is 20 to 60 wt% based on the total weight of the nicotine pouch packaging material.

[0044] Packaging materials for nicotine pouches may be safe for the human body, capable of retaining saliva well, have a certain strength to prevent tearing, and have sealing properties.

[0045] The packaging material for the nicotine pouch may be a nonwoven or woven type, preferably a nonwoven type. Unlike the woven type, the fibers of the nonwoven type are intertwined, so there is no longitudinal or transverse direction, and the cut edges may not fray.

[0046] Preferably, in the packaging material for a nicotine pouch according to one embodiment of the present invention, the content of the cellulose fiber may be 55 to 65 wt% relative to the total weight of the packaging material for the nicotine pouch, and the content of the thermoplastic material fiber may be 35 to 45 wt% relative to the total weight of the packaging material for the nicotine pouch.

[0047] In a packaging material for a nicotine pouch according to one embodiment of the present invention, the weight ratio of the cellulose fiber and the thermoplastic material fiber may be 4:6 to 8:2, preferably 6:4 to 8:2, and more preferably 6:4.

[0048] Cellulose fibers can increase the airtightness and physical strength of the packaging material for a nicotine pouch, and thermoplastic material fibers can be added to seal the nicotine pouch. However, when the content of the cellulose fibers is lower than the numerical range described above and the content of the thermoplastic material fibers is higher than the numerical range described above, the tensile strength of the packaging material for a nicotine pouch is low and the nicotine pouch may be easily torn. On the other hand, when the content of the cellulose fibers is higher than the numerical range described above and the content of the thermoplastic material fibers is lower than the numerical range described above, the seal strength of the packaging material for a nicotine pouch is lowered, the pouch may be easily burst, and the filler filled inside may be easily escaped.

[0049]

[0050] Cellulose fibers can not only increase the tensile strength of packaging materials for nicotine pouches, but also improve the usability (softness).

[0051] For example, the cellulose fiber may include not only cellulose but also cellulose-based fibers. The cellulose-based fibers may include at least one of natural cellulose-based fibers or artificial cellulose-based fibers.

[0052] The natural cellulosic fiber may include at least one selected from the group consisting of seed hair fiber, bast fiber, leaf fiber, and wood fiber (pulp). For example, the seed hair fiber may include cotton, bombax, kapok, etc. For example, the bast fiber may include hemp, flax, jute, ramie, paper mulberry, paper mulberry, etc. For example, the leaf fiber may include Manila hemp, New Zealand hemp, etc. For example, the wood fiber (pulp) may include at least one of softwood pulp and hardwood pulp depending on the type and characteristics of the tree, and for example, may include coniferous fiber, broadleaf fiber, etc.

[0053] The man-made cellulosic fiber may include at least one of regenerated cellulosic fibers or semi-synthetic fibers. Examples of regenerated cellulosic fibers include viscose, rayon, and polyurethane. Examples of semi-synthetic fibers include acetate rayon.

[0054] Rayon can include not only rayon but also rayon-based fibers that complement rayon's shortcomings. Examples of rayon-based fibers include Tencel, Lyocell, and Modal.

[0055] Preferably, in the packaging material for a nicotine pouch according to one embodiment of the present invention, the cellulose fiber may include at least one selected from the group consisting of cellulose, viscose, rayon, and pulp.

[0056] In the packaging material for a nicotine pouch according to one embodiment of the present invention, if the cellulose fibers are pulp, the pulp may be beaten. "Beating" may mean pulverizing the fibers by mechanically cutting them in water. Through beating, the pulp changes the length and structure of the fibers, making them more susceptible to hydrogen bonding, thereby imparting physical strength to the pouch material.

[0057]

[0058] By including thermoplastic material fibers, the packaging material for nicotine pouches can be heat sealed.

[0059] In a packaging material for a nicotine pouch according to one embodiment of the present invention, the thermoplastic material fiber may include at least one selected from the group consisting of nylon, polylactic acid, polyethylene, polypropylene, polyethylene / polypropylene, polyethersulfone, polyethylene terephthalate, and low-melting point polyethylene terephthalate (LMPET).

[0060] In addition, in the packaging material for a nicotine pouch according to one embodiment of the present invention, the thermoplastic material fiber is a dual-component fiber comprising two selected from the group consisting of polypropylene, polyethylene, polyethylene terephthalate, and polylactic acid, and the thermoplastic material fiber may form a core-shell structure. Such a core-shell structured fiber has the advantage of excellent physical properties and excellent sealing properties at low temperatures.

[0061] The thermoplastic material fiber may include staple fibers. Staple fibers are fibers having a discontinuous length, which may be cut from continuous filaments.

[0062]

[0063] In a packaging material for a nicotine pouch according to one embodiment of the present invention, the basis weight of the packaging material for the nicotine pouch is 10 g / m 2 50 g / m 2 , preferably 30 g / m 2 It could be.

[0064] If the basis weight of the packaging material for a nicotine pouch falls below the numerical range described above, the strength of the nicotine pouch material may be weakened. Conversely, if the basis weight of the packaging material for a nicotine pouch exceeds the numerical range described above, moisture movement may become difficult when the nicotine pouch is used, which may inhibit the release of the active ingredients of the filler (nicotine, flavor, etc.).

[0065]

[0066] In a packaging material for a nicotine pouch according to one embodiment of the present invention, the thickness of the packaging material for the nicotine pouch may be 50 μm to 150 μm, preferably 100 μm.

[0067] If the thickness of the packaging material for a nicotine pouch falls below the above-mentioned numerical range, the nicotine pouch may easily burst. Conversely, if the thickness of the packaging material for a nicotine pouch exceeds the above-mentioned numerical range, moisture movement may become difficult during use of the nicotine pouch, which may inhibit the release of the active ingredients of the filler (nicotine, flavoring, etc.).

[0068]

[0069] In a packaging material for a nicotine pouch according to one embodiment of the present invention, the airtightness of the packaging material for the nicotine pouch may be 5 mg to 100 mg, preferably 10 mg to 60 mg. In particular, if the airtightness of the packaging material for the nicotine pouch exceeds the numerical range described above, the filler may leak.

[0070]

[0071] In a packaging material for a nicotine pouch according to one embodiment of the present invention, the tensile strength of the packaging material for the nicotine pouch is 0.1 N / mm. 2 5 N / mm 2 , preferably 1 N / mm 2 1.4 N / mm 2If the tensile strength of the packaging material for the nicotine pouch is below the numerical range described above, the nicotine pouch may burst during manufacturing or oral use of the nicotine pouch.

[0072]

[0073] In a packaging material for a nicotine pouch according to one embodiment of the present invention, the seal strength of the packaging material for the nicotine pouch is 0.02 N / mm. 2 0.3 N / mm 2 , preferably 0.04 N / mm 2 0.25 N / mm 2 It is desirable that the seal strength of the packaging material for the nicotine pouch be high. On the other hand, if the seal strength of the packaging material for the nicotine pouch is below the numerical range described above, the packaging material for the nicotine pouch may easily burst, and the nicotine pouch may easily burst, causing the filler contained therein to easily escape.

[0074]

[0075] According to one embodiment of the present invention, a nicotine pouch including a nicotine pouch filler and a packaging material for a nicotine pouch can be provided. The packaging material for the nicotine pouch includes: cellulose fiber; and thermoplastic material fiber; wherein the content of the cellulose fiber may be 40 to 80 wt% based on the total weight of the packaging material for the nicotine pouch, and the content of the thermoplastic material fiber may be 20 to 60 wt% based on the total weight of the packaging material for the nicotine pouch.

[0076]

[0077] In a nicotine pouch according to one embodiment of the present invention, the nicotine pouch filler may include: nicotine; a release-controlling excipient including at least one selected from the group consisting of cellulose and sugar alcohol; a binder; a pH regulator; and a flavoring agent.

[0078] In the above nicotine pouch filler, nicotine may include a nicotine salt, and the type of nicotine salt may include, for example, at least one selected from the group consisting of nicotine salt benzoate, nicotine salt tartrate, nicotine salt malate, and nicotine salt salicylate.

[0079] The nicotine content can be determined based on the intended strength of the nicotine pouch. If the nicotine content falls below the range described above, it may be difficult for smokers to experience a satisfying smoking experience. Conversely, if the nicotine content exceeds the range described above, the nicotine stimulation may be excessive.

[0080] In the above nicotine pouch filler, the release-controlling excipient can play a role in controlling the nicotine release rate.

[0081] In the above nicotine pouch filler, the binder may include, for example, at least one selected from the group consisting of povidone K-25, hydroxypropylcellulose (HPC), low substituted hydroxypropylcellulose (L-HPC), hydroxypropylmethylcellulose (HPMC), and carboxymethylcellulose (CMC).

[0082] The binder can be added by wet binder addition or dry binder addition.

[0083] The pH adjusting agent can adjust the pH of the nicotine pouch filler to a pH at which nicotine can be absorbed, so that when the nicotine pouch is inserted into the oral cavity, the nicotine can be converted into a free-based nicotine form that can be rapidly absorbed. The pH of the nicotine pouch filler can be from 8.3 to 8.5. The pH adjusting agent can be, for example, at least one selected from the group consisting of sodium bicarbonate and sodium carbonate.

[0084] Flavorings can be anything that provides taste to satisfy the smoker's preference and are not limited to any particular flavoring.

[0085] Packaging materials for nicotine pouches can contain a certain amount of the above-mentioned filler. Packaging materials for nicotine pouches can be packaged so that the filler inside does not leak during transportation or use after being packaged, and can be manufactured so that smokers do not experience a foreign body sensation in their mouths when using the pouch.

[0086]

[0087] According to one embodiment of the present invention, a method for manufacturing a nicotine pouch may be provided, comprising: a step (S1) of manufacturing a dispersion of cellulose fibers and thermoplastic material fibers; a step (S2) of moving the dispersion to a paper machine to form a packaging material for a nicotine pouch; and a dehydration and drying step (S3); wherein the packaging material for the nicotine pouch includes cellulose fibers; and thermoplastic material fibers; wherein the content of the cellulose fibers is 40 to 80 wt% based on the total weight of the packaging material for the nicotine pouch, and the content of the thermoplastic material fibers is 20 to 60 wt% based on the total weight of the packaging material for the nicotine pouch.

[0088] In a method for manufacturing a nicotine pouch according to one embodiment of the present invention, the method for manufacturing the packaging material for the nicotine pouch may be a wet manufacturing method. Using the wet manufacturing method, a packaging material for the nicotine pouch with a uniform airtightness can be manufactured.

[0089]

[0090] Below, each step is explained in detail.

[0091] Step S1 is a step for preparing a dispersion of cellulose fibers and thermoplastic fibers. In this step, the cellulose fibers and thermoplastic fibers can be evenly dispersed in a solvent. The solvent may be water.

[0092] In a method for manufacturing a packaging material for a nicotine pouch according to one embodiment of the present invention, step S1 may optionally include beating the cellulose fibers. That is, in this case, step S1 may include: a step of beating the cellulose fibers; and a step of mixing the beating cellulose fibers with thermoplastic material fibers to prepare a dispersion. For example, the cellulose fibers may be pulp. Pulp can impart physical strength to the pouch material through this step.

[0093]

[0094] Step S2 involves transferring the previously manufactured dispersion to a paper machine to form packaging material for nicotine pouches. In step S2, the paper machine can be a machine that uniformly supplies the dispersion to rapidly and mass-produce continuous webs.

[0095]

[0096] Step S3 is a dehydration and drying step. The dispersion supplied in step S3 can be dehydrated and dried, thereby ultimately forming a packaging material for a thin nicotine pouch.

[0097]

[0098] In a method for manufacturing a nicotine pouch according to one embodiment of the present invention, after step S3, a step of sealing a nicotine pouch packaging material filled with a nicotine pouch filler may be further included. In this step, a thermal or ultrasonic welding method may be used, and at this time, the nicotine pouch packaging material may be sealed by controlling conditions such as temperature according to the type of thermoplastic material fiber and / or the manufacturing conditions of the packaging material.

[0099]

[0100] Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited to the following examples.

[0101]

[0102] 1. Manufacturing of packaging materials for nicotine pouches

[0103] Manufacturing Example 1

[0104] A packaging material for a nicotine pouch was manufactured containing cellulose fibers and thermoplastic fibers in a weight ratio of 6:4. Soft pulp made from coniferous wood was used as the cellulose fiber, and core-shell type polypropylene / polyethylene fibers were used as the thermoplastic fiber. The manufacturing method is as follows.

[0105] First, the soft pulp was refined and then mixed with core-shell type polypropylene / polyethylene fibers and water to produce a dispersion. The dispersion was transferred to a paper machine, dehydrated, and dried to ultimately obtain a packaging material for a nicotine pouch.

[0106]

[0107] Manufacturing Example 2

[0108] It was manufactured in the same manner as Manufacturing Example 1, except that the cellulose fiber and thermoplastic material fiber were included in a weight ratio of 4:6.

[0109]

[0110] Manufacturing Example 3

[0111] It was manufactured in the same manner as Manufacturing Example 1, except that the cellulose fiber and thermoplastic material fiber were included in a weight ratio of 8:2.

[0112]

[0113] Comparative Example 1

[0114] It was manufactured using the same method as Manufacturing Example 1, except that the spunlacing manufacturing method was used.

[0115]

[0116] 2. Experimental Example 1: Evaluation of the Airtightness of Packaging Materials for Nicotine Pouches

[0117] The airtightness of Manufacturing Examples 1 to 3 and Comparative Example 1 was evaluated. The airtightness was measured by the following method. First, the manufactured packaging material for nicotine pouches was placed between circular sieves having a diameter of 21 cm. At this time, the upper circular sieve was 10 mesh (sieve opening size: 2 mm), and the lower circular sieve was 12 mesh (sieve opening size: 1.7 mm). Then, 40 g of granular filler (average particle size: 250 μm) was placed on the upper circular sieve, and after shaking, the weight of the filler remaining on the lower sieve was measured for evaluation. The results are shown in Table 1 below.

[0118] Density of the discriminator Manufacturing example 1 Good (22 mg) Manufacturing example 2 Good (57 mg) Manufacturing example 3 Good (11 mg) Comparative example 1 Poor (850 mg)

[0119]

[0120] Manufacturing Examples 1 to 3, unlike Comparative Example 1, confirmed that 11 mg to 57 mg of filler remained in the lower mesh, resulting in good airtightness.

[0121] In light of the results of Manufacturing Examples 1 to 3, it was confirmed that the higher the cellulose content and the lower the thermoplastic fiber content, the more airtight the seal.

[0122]

[0123] 3. Experimental Example 2: Evaluation of the Softness of Packaging Materials for Nicotine Pouches

[0124] A sensory evaluation was conducted to evaluate the soft characteristics of Manufacturing Examples 1 to 3 and Comparative Example 1. The sensory evaluation was conducted by manufacturing the Manufacturing Examples and Comparative Examples in 28 mm × 15 mm pouches, and five evaluation panelists used them orally to evaluate them on a 5-point scale. The results are shown in Table 2.

[0125] Soft characteristics Manufacturing example 14.4 Manufacturing example 23.1 Manufacturing example 34.7 Comparative example 14.5

[0126]

[0127] Through the above Table 2, it can be seen that Manufacturing Examples 1 and 3 exhibit particularly soft characteristics compared to Manufacturing Example 2.

[0128]

[0129] 4. Experimental Example 3: Evaluation of Tensile Strength and Seal Strength of Packaging Materials for Nicotine Pouches

[0130] The tensile strength and seal strength of Manufacturing Examples 1 to 3 and Comparative Example 1 were evaluated. The tensile strength was evaluated by cutting the Manufacturing Examples and Comparative Examples into a size of 15 mm in width and 20 mm in length or more and applying the EDANA NWEP 110.1.R10 measurement method. The seal strength was evaluated by cutting the Manufacturing Examples and Comparative Examples into two pieces of 15 mm in width and 20 mm in length or more, sealing the transverse ends using a manual heat sealer (2 mm in width, 150°C, 2 seconds), and applying the above tensile strength measurement method. The results are shown in Table 3.

[0131] Tensile strength (N / mm) 2 )Seal strength (N / mm) 2 ) Manufacturing Example 11.30.25 Manufacturing Example 20.4 Not Measurable Manufacturing Example 34.00.04 Comparative Example 11.50.23

[0132]

[0133] In Manufacturing Example 2, the seal strength was higher than the tensile strength, so the seal strength could not be measured.

[0134] In light of the results of Manufacturing Examples 1 to 3, as the amount of cellulose fibers increased and the amount of thermoplastic fibers decreased, the tensile strength increased, but the seal strength tended to decrease. Manufacturing Example 1 showed excellent results in both tensile strength and seal strength.

[0135]

[0136] From the above experimental examples, it is predicted that by using the packaging material for a nicotine pouch described in the claims, a nicotine pouch that is airtight, soft, and has excellent tensile strength can be manufactured.

[0137]

[0138] Although the embodiments described above have been described with limited drawings, those skilled in the art will appreciate that various technical modifications and variations can be applied based on the above. For example, appropriate results can still be achieved even if the described techniques are performed in a different order than described, and / or components of the described systems, structures, devices, circuits, etc. are combined or combined in a different manner than described, or are replaced or substituted with other components or equivalents.

[0139]
