For example, depending on the properties of the compound, it can be analyzed using a GPC (Gel Permeation Chromatography) or GFC (Gel Filtration Chromatography) instrument. For instance, in the GPC analysis method, a sample sample with a concentration of 1 wt% of the compound is prepared by placing tetrahydrofuran (THF) and the compound in a 1 ml glass vial. The sample sample and a standard sample (polystyrene) are filtered through a filter (pore size 0.45 μm), and then injected into a GPC injector. The elution time of the sample sample is compared with the calibration curve of the standard sample to obtain the molecular weight and molecular weight distribution of the compound. In this case, an Infinity II 1260 (Agilient) can be used as the measuring instrument, with a flow rate of 1.00 mL / min and a column temperature of 40.0 °C.

Specifically, the organic acid may include citric acid and citric acid hydrate, and more specifically, the organic acid may include citric acid monohydrate. According to one embodiment of the present invention, when citric acid or citric acid monohydrate is used as the organic acid, the pH of nicotine can be lowered and the absorption rate by the human body can be further increased. 【0040】 The organic acid hydrates mentioned above may be any one of the factors that affect the moisture content of the aerosol product sheet. By using the organic acid hydrates mentioned above, it is possible to not only minimize the heat sensation felt by the user, but also to realize an aerosol product sheet with excellent mechanical properties, such as not tearing when wound up. 【0041】 Aerosol-forming substances In this specification, "aerosol" can be defined as a mixture of air or other gases in which fine solid particles or droplets are mixed and suspended. 【0042】 According to one embodiment of the present invention, the sheet for aerosol products includes an aerosol-forming substance that generates an aerosol when the aerosol product is inserted into an aerosol generating device and heated. Furthermore, the aerosol-forming substance not only generates an aerosol but is also one of the factors that adjust the moisture content of the sheet for aerosol products, and can simultaneously affect the heat sensation felt by the user when smoking and the ease of winding the sheet for aerosol products. 【0043】 According to one embodiment of the present invention, the content of the aerosol-forming substance may be 5 to 50 parts by weight, 8 to 47 parts by weight, 10 to 45 parts by weight, 12 to 40 parts by weight, 14 to 38 parts by weight, or 15 to 35 parts by weight, based on 100 parts by weight of the aerosol product sheet. Specifically, the content of the aerosol-forming substance may be 20 to 30 parts by weight, 23 to 25 parts by weight, or 27 to 30 parts by weight, based on 100 parts by weight of the aerosol product sheet.

Specifically, the content of the aerosol-forming substance may be 20% to 30% by weight, 23% to 25% by weight, or 27% to 30% by weight, based on the total weight of the aerosol product sheet. By adjusting the content of the aerosol-forming substance within the above numerical range, when the aerosol product sheet is heated, sufficient aerosols can be generated to promote the transfer of active substances. 【0044】 For example, the aerosol-forming substance may include one or more selected from the group consisting of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. Specifically, it may include glycerin. 【0045】 support According to one embodiment of the present invention, the sheet for aerosol products includes a support.

The water-insoluble porous material can reversibly adsorb active substances, aerosol-forming substances, and the like. That is, during storage of the aerosol product sheet, the volatilization of active substances, aerosol-forming substances, additives, and other components from the aerosol product sheet can be minimized. Furthermore, when the aerosol product sheet is heated, the active substances, aerosol-forming substances, additives, and other components adsorbed on the water-insoluble porous material can be detached from the water-insoluble porous material and aerosolized. 【0048】 According to one embodiment of the present invention, the water-insoluble porous material can be any material used in the industry without limitation, as long as it can reversibly adsorb components such as active substances and aerosol-forming substances.

For example, the cellulose derivative material may be esterified cellulose or etherified cellulose. Specifically, the water-insoluble porous material may include microcrystalline cellulose (MCC), but the type of water-insoluble porous material is not limited to this. 【0049】 According to one embodiment of the present invention, the content of the support may be 20 parts by weight or more and 80 parts by weight or less based on 100 parts by weight of the aerosol product sheet.

When the content of the support is within the range described above, the volatilization of active substances, aerosol-forming substances, etc., is minimized while ensuring the mechanical properties of the aerosol product sheet, and the strength and durability of the aerosol product sheet can be effectively improved. Furthermore, by adjusting the content of the support to the range described above, aerosols can be effectively generated when the aerosol product sheet is heated. 【0050】 binder According to one embodiment of the present invention, the sheet for aerosol products includes a binder substance.

Furthermore, the binder content may be 3% by weight or more and 15% by weight or less, 4% by weight or more and 12% by weight or less, 5% by weight or more and 10% by weight or less, 3% by weight or more and 8% by weight or less, or 4% by weight or more and 15% by weight or less based on the total weight of the aerosol product sheet. When the binder content is within the above ranges, the active substance, aerosol-forming substance, flavoring agent, etc. can be stably retained in the aerosol product sheet while ensuring the mechanical properties of the aerosol product sheet. 【0057】 Bulking agent According to one embodiment of the present invention, the sheet for aerosol products includes a bulking agent. The bulking agent can increase the volume of the sheet for aerosol products by increasing the total mass of components other than water in the composition for forming the sheet for aerosol products. Furthermore, the bulking agent does not substantially increase the viscosity of the composition for forming the sheet for aerosol products. 【0058】 According to one embodiment of the present invention, the bulking agent may include at least one of starches and starch hydrolysates. Starch hydrolysates can mean substances obtained by a process that includes a step of hydrolyzing starch. Starch hydrolysates may be, for example, substances obtained by directly hydrolyzing starch (i.e., dextrin) or substances obtained by hydrolyzing starch after heat treatment (i.e., indigestible dextrin). For example, the bulking agent may include dextrin. Specifically, the bulking agent may include at least one of cyclodextrin and maltodextrin. However, the type of dextrin is not limited thereto. 【0059】 According to one embodiment of the present invention, the bulking agent may include a starch hydrolysate with a DE value of 1 to 20. For example, the DE value of the starch hydrolysate may be 2 to 18, 3 to 15, 5 to 10, 10 to 20, 12 to 18, 1 to 5, or 1 to 10. Specifically, the starch hydrolysate may include at least one of dextrin having a DE value of 1 to 5 and indigestible dextrin having a DE value of 10 to 20. More specifically, the bulking agent may include dextrin as the starch hydrolysate. By using a bulking agent containing a starch hydrolysate having the aforementioned DE value, it is possible to prevent the sheet from shrinking during the manufacturing process and storage of the aerosol product sheet. This improves the processability during manufacturing of the aerosol product sheet and improves storage stability. 【0060】 DE is an abbreviation for dextrose equivalent, and the DE value is a value that indicates the degree of hydrolysis of starch, that is, the saccharification rate of starch. In this invention, the DE value is a value measured by the Willstatter-Schudel method. The DE value is measured as a specific numerical value by the Willstatter-Schudel method. The properties of hydrolyzed starch (starch hydrolysate), such as the molecular weight of the starch hydrolysate and the arrangement of sugar molecules constituting the starch hydrolysate, are not constant for each starch hydrolysate molecule, but exist with a certain distribution or variation. Due to the distribution or variation of the properties of the starch hydrolysate, or differences in the cut intervals, each starch hydrolysate molecule exhibits different physical properties (e.g., DE value). Thus, although starch hydrolysates are a collection of molecules exhibiting different physical properties, the measurement results obtained using the Willstatter-Schudel method (i.e., the DE value) are treated as a representative value indicating the degree of starch hydrolysis. 【0061】 According to one embodiment of the present invention, the content of the bulking agent may be 1 part by weight or more and 20 parts by weight or less based on 100 parts by weight of the aerosol product sheet. Specifically, the content of the bulking agent may be 2 parts by weight or more and 15 parts by weight or less, 5 parts by weight or more and 10 parts by weight or less, 8 parts by weight or more and 20 parts by weight or less, 8 parts by weight or more and 15 parts by weight or less, 1 part by weight or more and 10 parts by weight or less, or 5 parts by weight or more and 20 parts by weight or less based on 100 parts by weight of the aerosol product sheet. Furthermore, based on the total weight of the aerosol product sheet, the content of the bulking agent may be 1% by weight or more and 20% by weight or less, 2% by weight or more and 15% by weight or less, 5% by weight or more and 10% by weight or less, 8% by weight or more and 20% by weight or less, 8% by weight or more and 15% by weight or less, 1% by weight or more and 10% by weight or less, or 5% by weight or more and 20% by weight or less.

Furthermore, by adjusting the content of the bulking agent to the aforementioned range, the flavor retention period of the aerosol product sheet can be extended, and the water solubility, thermal stability, and oxidation resistance of the flavor components can be improved. 【0062】 According to one embodiment of the present invention, if the binder contains a binder substance with a weight-average molecular weight of 250,000 g / mol or more and 2,000,000 g / mol or less, the content of the bulking agent may be 1 part by weight or more and 20 parts by weight or less, based on 100 parts by weight of the aerosol product sheet. Also, if the binder contains a binder substance with a weight-average molecular weight of 250,000 g / mol or more and 2,000,000 g / mol or less, the content of the bulking agent may be 1% by weight or more and 20% by weight or less, based on the total weight of the aerosol product sheet. 【0063】 According to one embodiment of the present invention, if the binder contains a binder substance with a weight-average molecular weight of 1,000,000 g / mol or more and 2,000,000 g / mol or less, the content of the bulking agent may be 8 parts by weight or more and 20 parts by weight or less, based on 100 parts by weight of the aerosol product sheet. Specifically, if the binder contains guar gum as a binder substance with a weight-average molecular weight of 1,000,000 g / mol or more and 2,000,000 g / mol or less, the content of the bulking agent may be 9 parts by weight or more and 17 parts by weight or less, 10 parts by weight or more and 15 parts by weight or less, 8 parts by weight or more and 10 parts by weight or less, 9 parts by weight or more and 12 parts by weight or less, or 8 parts by weight or more and 15 parts by weight or less, based on 100 parts by weight of the aerosol product sheet. Furthermore, if the binder contains guar gum with a weight-average molecular weight of 1,000,000 g / mol or more and 2,000,000 g / mol or less as a binder substance, the content of the bulking agent may be 8% to 20% by weight, 9% to 17% by weight, 10% to 15% by weight, 8% to 10% by weight, 9% to 12% by weight, or 8% to 15% by weight, based on the total weight of the sheet for the aerosol product. In this case, a bulking agent containing dextrin having a DE value of 1 to 5 can be used. 【0064】 When using a binder substance having the weight-average molecular weight described above, the sheet for aerosol products tends to shrink significantly during the manufacturing process and storage. Therefore, by adjusting the content of the bulking agent to the range described above, the problem of sheet shrinkage during the manufacturing process and storage of the sheet for aerosol products can be effectively suppressed. 【0065】 According to one embodiment of the present invention, if the binder contains a binder substance with a weight-average molecular weight of 250,000 g / mol or more and 700,000 g / mol or less, the content of the bulking agent may be 1 part by weight or more and less than 8 parts by weight, based on 100 parts by weight of the aerosol product sheet. Specifically, if the binder contains a cellulosic polymer with a weight-average molecular weight of 250,000 g / mol or more and 700,000 g / mol or less as a binder substance, the content of the bulking agent may be 1 part by weight or more and less than 8 parts by weight, 2 parts by weight or more and 6 parts by weight or less, 3 parts by weight or more and 5 parts by weight or less, or 1 part by weight or more and 5 parts by weight or less, based on 100 parts by weight of the aerosol product sheet. Furthermore, if the binder contains guar gum with a weight-average molecular weight of 250,000 g / mol or more and 700,000 g / mol or less as a binder substance, the content of the bulking agent may be 1% by weight or more and less than 8% by weight, 2% by weight or more and 6% by weight or less, 3% by weight or more and 5% by weight or less, or 1% by weight or more and 5% by weight or less, based on the total weight of the sheet for the aerosol product. In this case, a bulking agent containing dextrin having a DE value of 1 or more and 5 or less can be used, thereby achieving excellent moisture absorption properties. 【0066】 According to one embodiment of the present invention, if the binder contains a binder substance with a weight-average molecular weight of 10,000 g / mol or more and 50,000 g / mol or less, the content of the bulking agent may be 0 parts by weight or more but less than 1.0 part by weight, 0 parts by weight or more but 0.9 parts by weight or less, 0 parts by weight or more but 0.8 parts by weight or less, 0 parts by weight or more but 0.7 parts by weight or less, 0 parts by weight or more but 0.6 parts by weight or less, 0 parts by weight or more but 0.5 parts by weight or less, 0 parts by weight or more but 0.4 parts by weight or less, 0 parts by weight or more but 0.3 parts by weight or less, 0 parts by weight or more but 0.2 parts by weight or less, or 0 parts by weight or more but 0.1 parts by weight or less.

Specifically, if the binder contains a binder substance with a weight-average molecular weight of 10,000 g / mol or more and 50,000 g / mol or less, the aerosol product sheet does not need to contain a bulking agent. More specifically, if the binder contains a cellulosic polymer with a weight-average molecular weight of 10,000 g / mol or more and 50,000 g / mol or less as a binder substance, the sheet for the aerosol product does not need to contain a bulking agent. 【0067】 When using a binder substance having the weight-average molecular weight described above, the sheet for aerosol products tends to shrink less during the manufacturing process and storage. Therefore, by adjusting the content of the bulking agent to the range described above, it is possible to suppress the shrinkage of the sheet during the manufacturing process and storage while still ensuring that the sheet for aerosol products has an appropriate volume. This improves the tobacco properties of the sheet for aerosol products. 【0068】 In other words, according to one embodiment of the present invention, by adjusting the content of the bulking agent in consideration of the weight-average molecular weight of the binder substance contained in the aerosol product sheet, it is possible to improve the smoking properties while effectively suppressing the shrinkage of the aerosol product sheet. 【0069】 Moisture adjuster According to one embodiment of the present invention, the sheet for aerosol products may include a moisture adjusting agent.

Specifically, if the moisture content of the sheet for aerosol products is high, it can be easily wound up, but the amount of water vapor that vaporizes increases, which can lead to a problem where the heat sensation intensity felt by the user increases. On the other hand, if the moisture content of the sheet for aerosol products is low, the amount of water vapor that vaporizes decreases, which reduces the heat sensation intensity, but it can lead to a problem where the mechanical properties of the sheet deteriorate, such as tearing when wound up. In other words, there is a trade-off relationship between heat sensation performance and mechanical properties, where if one performance is improved, the other performance decreases. 【0099】 According to one embodiment of the present invention, the moisture content of the aerosol product sheet may be 3 to 15 parts by weight, 5 to 8 parts by weight, 5 to 12 parts by weight, 4 to 12 parts by weight, 4.2 to 8 parts by weight, 5 to 8 parts by weight, or 6 to 7 parts by weight, based on 100 parts by weight of the aerosol product sheet.

According to one embodiment of the present invention, by adjusting the moisture content of the aerosol product sheet to within the aforementioned numerical range, it is possible to achieve both of the aforementioned trade-off performances. In other words, according to one embodiment of the present invention, it is possible to realize an aerosol product sheet that minimizes the heat sensation felt by the user when smoking and also has excellent mechanical properties. 【0100】 Tobacco substances According to one embodiment of the present invention, the aerosol product sheet may contain trace amounts of tobacco substances or may not contain any tobacco substances at all.

Here, "crimping" can include one or more structures selected from the group consisting of convex structures, concave structures, and perforated structures, and more specifically, it can include structures that combine convex and concave structures, and more specifically, it can mean structures that have multiple wrinkles. 【0136】 According to one embodiment of the present invention, the plurality of wrinkles in the aerosol product sheet 10 included in the second portion SEG2 can extend parallel to the longitudinal axis of the aerosol product. By the plurality of wrinkles extending parallel to the longitudinal axis of the aerosol product, a desired flow of aerosol generated by heating the aerosol product sheet can be provided, thereby achieving an appropriate level of suction resistance. 【0137】 According to one embodiment of the present invention, the second portion SEG2 does not need to contain tobacco substances. By not containing tobacco substances in the second portion SEG2, the active substance can be effectively transferred to the user even without tobacco substances, further improving taste and satisfaction. Specifically, tobacco substances such as tobacco leaves have the problem of having a characteristic flavor that acts as an unpleasant odor to the user, and as the tobacco leaves are heated, other components other than the active substance (nicotine or nicotine salt) are transferred to the user's mouth. By removing tobacco substances from the second portion, the problem of unpleasant odor and the problem of transfer of other components can all be solved. 【0138】 According to one embodiment of the present invention, the first part SEG1 may include a first filter element. For example, the first filter element may be made of cellulose acetate. In some examples, the first filter element may be an aggregate (tow) of continuous filaments made of cellulose acetate. For example, the first filter element may include a hollow formed along the longitudinal direction of the aerosol product 100, where the hollow can penetrate the first filter element. The cross-sectional shape of the hollow is not particularly limited and may be Y-shaped, X-shaped, or circular. 【0139】 According to one embodiment of the present invention, the first filter element may include a first sub-aerosol-forming material that is the same as or different from the aerosol-forming material contained in the aerosol product sheet described above. For example, the first sub-aerosol-forming material may be impregnated into the first filter element. The atomization generated by heating the first sub-aerosol-forming material can effectively transfer active substances such as nicotine or nicotine salts generated in the aerosol product sheet contained in the second partial SEG2 downstream. 【0140】 According to one embodiment of the present invention, the third portion SEG3 may include a second filter element.

In some examples, the third filter element is not particularly limited and may be a filter commonly used in the art. Specifically, the third filter element may be an assembly (tow) of continuous filaments made of cellulose acetate. 【0142】 Figure 3 is a schematic diagram showing an aerosol generating apparatus according to another embodiment of the present invention. Explanations that overlap with those in Figures 1 and 2 are briefly explained or omitted. Referring to Figure 3, an aerosol generator 300 according to one embodiment of the present invention may further include a cartridge 340 containing a second subaerosol-forming material having one of the following states: liquid, solid, gaseous, or gel. For example, the second subaerosol-forming material may include a liquid composition. Specifically, the liquid composition may be a liquid containing a non-tobacco substance and may contain the aerosol-forming material described above. 【0143】 For example, the second sub-aerosol-forming material contained in the cartridge 340 can generate an aerosol by heating. The generated aerosol is transported through the airflow channel to the first part SEG1 of the aerosol product 100, which can promote the downstream transfer of nicotine or nicotine salt released from the aerosol product sheet 10 contained in the second part SEG2. 【0144】 According to one embodiment of the present invention, the first portion SEG1 may include a fourth filter element to filter out some components of the aerosol supplied from the cartridge 340. The first portion SEG1 may also recognize the aerosol product 100 by including aluminum foil as the filter wrapping paper. For example, the fourth filter element may include a tube filter commonly used in the art. 【0145】 According to one embodiment of the present invention, the second portion SEG2 may include the aerosol product sheet 10 described above. By including the aerosol product sheet in the second portion SEG2, it is possible not only to reduce the transfer of aerosols containing components other than the active substance, but also to realize an aerosol product that is free from the characteristic odor of tobacco and has no off-odor. 【0146】 According to one embodiment of the present invention, the content of the aerosol product sheet per unit length of the second section SEG2 may be 150 mg / 12 mm to 280 mg / 12 mm, 160 mg / 12 mm to 270 mg / 12 mm, 170 mg / 12 mm to 260 mg / 12 mm, 180 mg / 12 mm to 250 mg / 12 mm, 190 mg / 12 mm to 240 mg / 12 mm, 200 mg / 12 mm to 230 mg / 12 mm, or 230 mg / 12 mm to 280 mg / 12 mm. According to one embodiment of the present invention, by adjusting the content of the aerosol product sheet within the above range, the active substance can be sufficiently transferred to the mouth end, further improving the taste performance and satisfaction. 【0147】 According to one embodiment of the present invention, the second part SEG2 does not need to contain tobacco substances. By not containing tobacco substances in the second part SEG2, the active substance can be effectively transferred to the user even without tobacco substances, further improving taste and satisfaction. Specifically, tobacco substances such as tobacco leaves have the problem of having a characteristic flavor of tobacco leaves that acts as an unpleasant odor to the user, and the problem that as the tobacco leaves are heated, other components other than the active substance (nicotine or nicotine salt) are transferred to the user's mouth. According to one embodiment of the present invention, by removing tobacco substances from the second part, the problem of unpleasant odor and the problem of transfer of other components can all be solved. 【0148】 For example, the heater 330 can heat both the first section SEG1 and the second section SEG2. For example, the description of the wrinkled structure of the aerosol product sheet 10 may be the same as the description given above in Figure 2. 【0149】 Figure 4 is a cross-sectional view showing a modified version of the aerosol product sheet shown in Figures 2 and 3. Specifically, the aerosol product sheet shown in Figure 4 is a cross-sectional view obtained by cutting the aerosol product sheet along the longitudinal axis L of the aerosol product 100. Alternatively, the aerosol product sheets shown in Figures 2 and 3 can be transformed into the aerosol product sheet shown in Figure 4. 【0150】 Referring to Figure 4, according to one embodiment of the present invention, the aerosol product sheet 10 may be a laminate in which two or more subsheets 10a are laminated together. For example, the subsheets may be manufactured by cutting a single aerosol product sheet. 【0151】 For example, the total number of subsheets 10a is not particularly limited, but specifically, it may be between 50 and 200 sheets. According to one embodiment of the present invention, at least one of the two or more subsheets 10a may include a crimped structure, specifically, all of the subsheets may include a crimped structure. According to one embodiment of the present invention, by including a crimped structure in all of the subsheets, the aerosol generated on the aerosol product sheet 10 can be transferred more effectively to nicotine or a nicotine salt. 【0152】 For example, the thickness of the subsheet 10a is not particularly limited, but may be 50 μm or more and 300 μm or less, 100 μm or more and 270 μm or less, 150 μm or more and 250 μm or less, 50 μm or more and 250 μm or less, or 150 μm or more and 300 μm or less. In this case, the thickness direction T of the subsheet 10a may be in a direction intersecting the longitudinal direction L of the aerosol product 100, and more specifically, it may be in a direction perpendicular to the longitudinal direction L of the aerosol product 100. 【0153】 [Examples] material To produce the active substance, nicotine and the organic acid citric acid monohydrate were prepared.

At this time, the experimental conditions were 22.5°C and 40% relative humidity, and the moisture content was measured after the dried sheet test specimen was exposed for 24 hours. 【0164】 Contraction rate evaluation The aerosol product sheet-forming compositions of Examples 1-2 and Comparative Examples 1-4 were cast onto a stainless steel plate to a thickness of 1 mm and an area of ​​250 mm x 250 mm, and then dried to produce sheets. During this process, drying was carried out at a temperature of 105°C for 10 minutes. 【0165】 The longest width (1) of the composition for forming aerosol products and the longest width (2) of the dried aerosol product sheet were measured. Subsequently, shrinkage rate evaluation was carried out based on the evaluation criteria below, and the results are shown in Table 3 below. 【0166】 O: If the value of (1)-(2) is less than 5 mm X: If the value of (1)-(2) is 5 mm or more Evaluation of sheet processability For the sheets produced in Examples 1 and 2 and Comparative Examples 1 and 3, a simple crimping machine was prepared in-house. An "X" was used if the sheet stuck to the crimping roller and crimping was difficult, and an "O" was used if the sheet did not stick to the roll and crimping was successful. The results are shown in Table 3 below. 【0167】 Evaluation of the storage stability of the sheet The sheets manufactured in Examples 1 and 2 and Comparative Examples 1 and 3 were subjected to storage stability evaluation using the method described below, and the results are shown in Table 3 below. 【0168】 The sheets were placed in a chamber under conditions of 50% humidity and 25°C, sealed, and left for 6 months. Thereafter, if cracks or breakage were visible to the naked eye, the sheet was evaluated as "X," and if no damage occurred to the sheet and moisture absorption increased its tackiness and elongation, it was evaluated as "O." 【0169】 Measurement of the tensile strength and elongation of the sheet The tensile strength and elongation of the sheets produced in the examples and comparative examples were measured using the method described in the international standard ISO 1924 / 2, published in 2014, entitled "Paper and boards - Determination of tensile properties - Part 2: Constant speed stretching method," and the measurement results are shown in Table 3 below. 【0170】 Specifically, in accordance with the ISO 1924 / 2:2014 testing standard, the tensile strength of a sheet test specimen for aerosol products (thickness: 210 μm, width: 15 mm, length: 100 mm) was measured in the longitudinal direction (MD direction; Machine direction) of the sheet using a vertical tensile strength testing machine (device name: Universal Tester Vertical; FRANK-PTI GMBH). At this time, the tensile speed of the sheet test specimen was set to 20 mm / min. 【0171】 [Table 3] 【0172】 Referring to Table 3 above, it was confirmed that the aerosol product sheets produced in Example 1 and Example 2 exhibited excellent results in terms of shrinkage rate, processability, and storage stability, while also demonstrating superior mechanical properties in terms of tensile strength and elongation. 【0173】 In contrast, in Comparative Examples 1 to 4, the evaluation results for shrinkage rate, processability, and storage stability deteriorated, and it was confirmed that the mechanical properties were also deteriorated compared to the examples. Therefore, it can be seen that the sheet for aerosol products according to one embodiment of the present invention has excellent processability, stability, and mechanical properties.
