Description

Technical Field

[0001] The present invention relates to a packaging material for cigarette butt recycling using multi-layer paper sheets. Specifically, it relates to a packaging material for cigarette butt recycling that can conveniently store and seal cigarette butts using multi-layer paper sheets and a manufacturing method thereof. Background Art

[0002] Cigarette butts discarded on the ground by smokers can be seen everywhere on the street. In particular, cigarette butts stuffed full can often be seen at sewer outlets, street rainwater inlets, etc.

[0003] According to a report by the World Health Organization (WHO), two-thirds of the world's cigarette sales are discarded on the ground in the form of cigarette butts. Based on the annual production of more than 6 trillion cigarettes, 4 trillion cigarette butts are discarded among them.

[0004] In particular, in 2018, 3.47 billion packs, approximately 70 billion cigarettes, were sold in South Korea. Assuming that two-thirds of them were discarded, it is estimated that more than 46 billion cigarette butts were discarded in South Korea last year, and 8.7 billion cigarette butts were randomly discarded in Seoul alone every year. Randomly discarding cigarette butts without discrimination has become the main cause of the backflow of rainwater inlets during the rainy season. According to the report, based on 2018, the maintenance cost of rainwater inlets in Seoul was as high as 7 billion won.

[0005] Moreover, among the marine litter collected from the world's coasts in the past 32 years, one-third is cigarette butts. According to a report by the Korea Marine Rescue Corps, from January to September 2018, among the litter collected from 32 coasts and the seabed in South Korea, cigarette butts accounted for 21%. Although a campaign to reduce plastic straws has been launched worldwide, it has been confirmed that straws only account for 0.02% in marine waste. It is known that cigarette butts can induce more serious problems than plastic bags or plastic bottles. Also, after cigarette butts sink and flow into the ocean, they become microplastics, damaging the ecological systems of lakes and the ocean, not only spoiling the urban beauty but also clogging sewers.

[0006] In the past, in order to solve the problem of randomly discarding cigarette butts, various methods for safely recycling cigarette butts for treatment have been studied.

[0007] For example, Korean Utility Model Registration No. 20-0345595 relates to a cigarette case with a built-in cigarette butt recycling bag and discloses the following: a cigarette butt recycling bag capable of loading cigarette butts and sealing the upper part; and a cigarette case with the above cigarette butt recycling bag, and the cigarette butt recycling bag is respectively disposed on one of the front or side of each of two sides or one side between the cigarette and the silver foil paper, between the silver foil paper and the outer packaging of the cigarette case, or between the outer packaging of the cigarette case and the plastic paper.

[0008] However, the existing publicly disclosed bag-shaped structures such as Document 1 have structures that are difficult to accommodate cigarette butts, resulting in problems of reduced convenience in use. Therefore, it is necessary to study methods to improve these problems. Summary of the Invention

[0009] Technical Problem

[0010] The present invention is proposed to solve the problems of the above-mentioned prior art. The object of the present invention is to provide technical content related to a packaging material for cigarette butt recycling having a structure capable of conveniently accommodating cigarette butts.

[0011] Furthermore, the object of the present invention is to provide content related to a packaging material for cigarette butt recycling using multi-layer paper sheets, which can form a culture of safely packaging, neatly accommodating, and recycling cigarette butts by ensuring flame retardancy.

[0012] The technical problems to be solved by the present invention are not limited to the problems mentioned above. Those of ordinary skill in the technical field to which the present invention pertains can clearly understand other technical problems not mentioned through the following description.

[0013] Technical Solution

[0014] The present invention relates to a packaging material for cigarette butt recycling using multi-layer paper sheets.

[0015] An embodiment of the present invention relates to a packaging material for cigarette butt recycling using multi-layer paper sheets, which is characterized in that it is formed by overlapping and joining multi-layer paper sheets, has a bag-like structure with an opening formed on one side to be able to accommodate cigarette butts, and the multi-layer paper sheets include: a metal sheet layer including an aluminum sheet; a first adhesive layer formed on one surface of the metal sheet layer; a second adhesive layer formed on the other surface of the metal sheet layer; a first paper sheet layer formed on the upper surface of the first adhesive layer; and a second paper sheet layer formed on the upper surface of the second adhesive layer. The first adhesive layer and the second adhesive layer are formed using an adhesive containing a modified polyolefin resin.

[0016] In this case, the present invention is characterized in that the packaging material for cigarette butt recycling is manufactured into the following bag form: it is made by joining the left and right sides and the lower side in a state where a first multi-layer paper sheet and a second multi-layer paper sheet having a quadrilateral structure are overlapped, and has a structure including a front part, a rear part, a joining part, an opening part, and a cover part. The first multi-layer paper sheet has an isosceles trapezoid shape with the left and right side lengths of the non-parallel sides being the same and the length of the upper side being longer than the length of the lower side, the second multi-layer paper sheet has a rectangular shape, and the length of the lower side of the first multi-layer paper sheet is the same as the length of the lower side of the second multi-layer paper sheet.

[0017] Moreover, the present invention is characterized in that the packaging material for cigarette butt recycling is in the form of a bag, and the bag form has a structure including a front part, a rear part, a joining part, an opening part, and a handle part. A multi-layer paper sheet with a quadrilateral structure is folded on both sides in the length direction to form the front part, the rear part, and the handle part respectively. In the folded state, the two ends and the lower end of the front part are joined respectively to form the joining part and the opening part.

[0018] Moreover, the packaging material for cigarette butt recycling is in the form of a bag, and the bag form has a structure including a front part, a rear part, a joining part, an opening part, a lid part, and a bending part. The length of the front part and the rear part can be made asymmetric by cutting the multi-layer paper sheet. The lid part is formed on the rear part by extending and protruding the upper end of the rear part longer than the upper end of the front part in the length direction. The bending part is formed on the front part and the rear part by pressing in from the outside to the inside of the bag in an "inverted V" shape. The joining part is formed by joining the two ends and the lower end of the front part and the rear part.

[0019] Moreover, the packaging material for cigarette butt recycling is manufactured into a fourth bag structure as follows: The packaging material for cigarette butt recycling is in the form of a bag, and the bag form has a structure including a front part, a rear part, a joining part, an opening part, and a triangular bottom part. The triangular bottom part is formed by vertically forming in the central area of the triangular front part and rear part formed at the lower ends of the front part and the rear part, and is unfolded to form a triangular surface. The front part and the rear part can be folded along the vertical folding part by cutting the multi-layer paper sheet, and the bottom surface is unfolded through the triangular bottom part, so as to be unfolded in a manner having an opening part and a capacity suitable for accommodating cigarette butts.

[0020] Moreover, the packaging material for cigarette butt recycling is manufactured into a fifth bag structure 10d as follows: The packaging material for cigarette butt recycling has a bag form including a front part, a rear part, a side part, a joining part formed by joining the two side edges of the side part to the front part and the rear part respectively, and an opening part, and includes a triangular folding part. A vertical folding part is formed along the vertical area in the center of the side part. The central lower end part of the side part located between the lower ends of the front part and the rear part is lifted upward to be folded into a triangular dome. As the triangular dome unfolds, the triangular folding part unfolds in the opposite direction. The front part, the rear part, and the side part can be manufactured by cutting the multi-layer paper sheet to overlap or unfold through the vertical folding part and the triangular folding part.

[0021] Moreover, the packaging material for cigarette butt recycling can be manufactured into a cigarette butt recycling cup with the following structure by cutting the multi-layer paper sheet, which includes: a side part, which is joined in a manner of forming a joining part and is in the shape of an inverted frustum of a cone; a circular opening part at the upper part, which is formed at the upper part through the side part; and a circular bottom part, which is used to cover the bottom surface.

[0022] Moreover, the present invention is characterized in that the modified polyolefin resin is a resin obtained by graft-modifying one or more unmodified polyolefin resins selected from ethylene-propylene copolymers, propylene-butene copolymers, and ethylene-propylene-butene copolymers with a modifier containing an α,β-unsaturated carboxylic acid or its derivative.

[0025] Moreover, the packaging material for cigarette butt recycling of the present invention can be easily opened to form an opening by pressing the upper edge portions on the left and right sides of the packaging material, so that cigarette butts can be conveniently stored. And because of its thin thickness, multiple of them can be joined together and easily separated and used one by one, which is convenient for carrying.

[0026] In particular, the bag for cigarette butt recycling of the present invention can prevent cigarette butts from being randomly discarded by improving the wrong smoking method of dropping or extinguishing the cigarette after smoking and then throwing away the cigarette butt, can form a culture of safely packaging, neatly storing, and recycling cigarette butts, and can contribute to the resource utilization of cigarette butts through reuse.

If not explicitly defined in this invention, they shall not be construed to have an ideal or overly formal meaning.

[0042] Hereinafter, the present invention will be described in detail.

[0043] Figure 1 FIG. is a conceptual diagram showing the structure of a multi-layer paper sheet as the present invention and a cigarette butt recycling bag 10 as an example of a packaging material for cigarette butt recycling.

[0044] Refer to Figure 1 , the cigarette butt recycling bag 10 of the present invention is manufactured using a multi-layer paper sheet 100 and has a bag-shaped structure in which an opening 14 can be formed on one side to accommodate cigarette butts.

[0045] The gas components generated from cigarette butts contain first-class carcinogens (substances that are clearly carcinogenic to humans) such as acetaldehyde, 2-naphthylamine, 4-aminobiphenyl, benzene, toluene, ethylene oxide, 1,1-dimethylhydrazine, arsenic, beryllium, nickel, chromium, cadmium, polonium-210, etc. In addition, it also contains more than 70 carcinogens.

[0046] Moreover, it also contains more than 7,000 toxic and harmful substances such as acetic acid, catechol, acrolein, acetone, etc., with nicotine that causes poisoning being the main one. Therefore, the impact of the airtightness of the bag on the surrounding environment plays a very important role.

[0047] Therefore, in order to prevent the malodor induced by cigarette butts from being discharged to the outside through airtight sealing and to prevent fires caused by cigarette butts, it is preferable that the multi-layer paper sheet 100 used to manufacture the bag 10 has a structure that introduces sufficient flame retardancy.

[0048] To this end, the multi-layer paper sheet 100 may use a structure including a metal sheet layer 110, a first adhesive layer 120, a second adhesive layer 130, a first paper sheet layer 140, and a second paper sheet layer 150.

[0049] Looking closely at the structure of the multi-layer paper sheet 100, the metal sheet layer 110 can be formed using an aluminum sheet, and an aluminum sheet with a thickness of 1 μm to 1000 μm can be introduced for use.

[0050] If the thickness of the metal sheet layer 110 is less than 1 μm, there will be a problem of reduced airtightness of the multi-layer paper sheet, and if the thickness is greater than 1000 μm, there will be a problem of difficulty in achieving lightweight of the multi-layer paper sheet 100.

[0051] Preferably, the thickness of the metal sheet layer 110 can be 3 μm to 500 μm, and more preferably, the thickness of the metal sheet layer 110 can be 5 μm to 30 μm.

[0052] In the multi-layer paper sheet 100, the first adhesive layer 120 and the second adhesive layer 130 can form the multi-layer paper sheet 100 by bonding the metal sheet layer 110 and the subsequent paper sheet layers 140 and 150 respectively, and the first adhesive layer 120 and the second adhesive layer 130 can be formed using an adhesive composition containing a modified polyolefin resin.

[0053] The modified polyolefin adhesive is a resin obtained by graft-modifying an unmodified polyolefin resin with a modifier containing α,β-unsaturated carboxylic acid or its derivative, has good adhesiveness with other layers, and also has excellent resistance to heat or chemical components.

[0054] Specifically, the modified polyolefin resin is a resin having a part derived from an unmodified polyolefin resin and a graft part derived from a modifier, and preferably, it is obtained by graft polymerization with a modifier containing α,β-unsaturated carboxylic acid or its derivative in the presence of an unmodified polyolefin resin. The modified polyolefin resin obtained by graft polymerization can be prepared by a known method, and it is preferably to use a radical initiator during the preparation.

[0055] Specifically, the preparation method of the modified polyolefin resin can be, for example, a solution method in which the unmodified polyolefin resin is heated and dissolved in a solvent such as toluene, and then the modifier and a solution of a radical initiator are added, or a melting method in which the unmodified polyolefin resin, the modifier, and the radical initiator are melt-kneaded using a Banbury mixer, a kneader, an extruder, etc. The usage methods of the unmodified polyolefin resin, the modifier, and the radical initiator are not particularly limited, and they can be added to the reaction system at one time, or they can be added successively.

[0056] In the case of preparing the modified polyolefin resin, a modifying aid for improving the grafting efficiency of α,β-unsaturated carboxylic acid, a stabilizer for adjusting the resin stability, etc. may also be used.

[0057] The unmodified polyolefin resin is not particularly limited as long as it has a structural unit derived from an olefin. Preferably, a single polymer or copolymer having 2 or more and 20 or less carbon atoms such as ethylene, propylene, butene, pentene, hexene, heptene, octene, 4-methyl-1-pentene, etc. is used. In the present invention, a single polymer or copolymer of an olefin having 2 or more and 6 or less carbon atoms is particularly preferred. The content ratio of the structural unit in the unmodified polyolefin resin can be arbitrarily selected, but when bonding a poorly adherent adherend, preferably, the modified polyolefin resin is a modified resin of ethylene-propylene, propylene-butene or ethylene-propylene-butene copolymer.

[0058] Moreover, particularly when it is desired to obtain outstanding adhesiveness, preferably, an unmodified polyolefin resin having a propylene unit content ratio of 50 mol% or more and 98 mol% or less is used. When the propylene unit content ratio is within the above range, flexibility can be imparted to the joint portion after joining of two members. And, the molecular weight of the unmodified polyolefin resin is not particularly limited.

[0059] The modifier contains an α,β-unsaturated carboxylic acid and its derivatives. The α,β-unsaturated carboxylic acid can be maleic acid, fumaric acid, tetrahydrophthalic acid, itaconic acid, citraconic acid, crotonic acid, aconitic acid, norbornene dicarboxylic acid, etc. And, the derivatives of the unsaturated polycarboxylic acid can be acid anhydrides, acid halides, amides, imides, esters, etc. Preferably, the modifier is itaconic anhydride, maleic anhydride, aconitic anhydride and citraconic anhydride, and from the viewpoint of adhesiveness, itaconic anhydride and maleic anhydride are preferred. When using a modifier, it is preferable to use one or more selected from α,β-unsaturated carboxylic acids and their derivatives, and it can be a combination of one or more α,β-unsaturated carboxylic acids and one or more of their derivatives, a combination of two or more α,β-unsaturated carboxylic acids, or a combination of two or more derivatives of α,β-unsaturated carboxylic acids.

[0060] According to the purpose, in addition to α,β-unsaturated carboxylic acids, etc., the modifier of the present invention may also contain other compounds (other modifiers). The other compounds (other modifiers) can be, for example, (meth)acrylates represented by the following Chemical Formula 1, (meth)acrylic acid, other (meth)acrylic acid derivatives, aromatic vinyl compounds, cyclohexyl vinyl ether, etc. These other compounds can be used alone or in combination of two or more.

[0061] Chemical Formula 1

[0062] CH2=CR 1 COOR2

[0063] In the formula, R 1 is a hydrogen atom or a methyl group, and R 2 is an alkyl group having 1 to 20 carbon atoms.

[0064] Specifically, R 1 is a hydrogen atom or a methyl group, and preferably, it is a methyl group. R 2 is a hydrocarbon group, and preferably, it is an alkyl group having 1 to 20 carbon atoms. The compound represented by the chemical formula 1 may be methyl (meth)acrylate, ethyl (meth)acrylate, propyl (meth)acrylate, butyl (meth)acrylate, pentyl (meth)acrylate, hexyl (meth)acrylate, heptyl (meth)acrylate, octyl (meth)acrylate, decyl (meth)acrylate, lauryl (meth)acrylate, tridecyl (meth)acrylate, stearyl (meth)acrylate, cyclohexyl (meth)acrylate, phenyl (meth)acrylate, etc. These compounds can be used alone or in combination of two or more.

[0065] In the present invention, from the viewpoint of improving heat-resistant adhesiveness, it is preferable to use a modifier further containing a (meth)acrylate having an alkyl group having 8 to 18 carbon atoms, and particularly preferably containing octyl (meth)acrylate, lauryl (meth)acrylate, tridecyl (meth)acrylate, or stearyl (meth)acrylate.

[0066] The (meth)acrylic acid derivatives other than (meth)acrylate may be 2-hydroxyethyl (meth)acrylate, glycidyl (meth)acrylate, (meth)acrylic acid containing isocyanate, etc. The aromatic vinyl compounds may be styrene, o-methylstyrene, p-methylstyrene, α-methylstyrene, etc. The modifier can improve the grafting rate of the modifier, or improve the solubility in a solvent, or further improve the adhesiveness by using an α,β-unsaturated carboxylic acid or its derivative in combination with other modifiers. And, when using other modifiers other than the (meth)acrylate represented by the chemical formula 1, it is preferable that the usage amount thereof does not exceed the limit of the usage amounts of the α,β-unsaturated carboxylic acid and its derivative and the (meth)acrylate.

[0067] As described above, the modified polyolefin resin has at least a graft portion derived from the modifier. Hereinafter, the content ratio of the graft portion contained in the modified polyolefin resin (hereinafter referred to as "graft mass") will be described.

[0068] The modified polyolefin resin has a graft portion derived from an α,β-unsaturated carboxylic acid or its derivative. In the modified polyolefin resin, from the viewpoint of adhesiveness, preferably, relative to 100 mass percentages of the modified polyolefin resin, the graft mass of the graft portion derived from an α,β-unsaturated carboxylic acid or its derivative is 0.1 to 20 mass percentages, and more preferably, it is 0.2 to 18 mass percentages. When the graft mass is 0.1 mass percentage or more, the solubility in a solvent is prominent, and the adhesiveness to an adherend formed of a metal or the like is particularly prominent. Also, when the graft mass is 20 mass percentages or less, sufficient adhesiveness to an adherend formed of a resin or the like can be obtained.

[0069] The graft mass of the graft portion derived from an α,β-unsaturated carboxylic acid or its derivative in the modified polyolefin resin can be determined by an alkali titration method. If the derivative of the α,β-unsaturated carboxylic acid is an imide or the like that does not contain an acid functional group, the graft mass can be determined by Fourier transform infrared spectroscopy.

[0070] Preferably, the weight average molecular weight (Mw) of the modified polyolefin resin is from 30,000 to 250,000, and more preferably, it is from 50,000 to 200,000. If the weight average molecular weight (Mw) satisfies the above range, the solubility in a solvent and the initial adhesiveness to an adherend are prominent, and also, it can be used as an adhesive composition having prominent solvent resistance at the joint portion after joining.

[0071] Preferably, the acid value of the modified polyolefin resin is from 0.1 mgKOH / g to 50 mgKOH / g, more preferably, it is from 0.5 mgKOH / g to 40 mgKOH / g, and even more preferably, it is from 1.0 mgKOH / g to 30 mgKOH / g. When the acid value satisfies the above range, the adhesive composition is sufficiently strengthened, and thus good adhesiveness, heat resistance, and resin bleeding resistance can be obtained.

[0072] Also, in order to further improve the antibacterial properties of the overall packaging material, the composition forming the adhesive layer may further contain an antibacterial polymer.

[0073] The antibacterial polymer can have excellent bactericidal and antibacterial power by having a cationic functional group such as an amino group as a functional group. Specifically, the bactericidal and antibacterial action of the amino group is exhibited by oligodynamic action. The oligodynamic action, also known as microbactericidal action, inhibits the action of the redox system by strongly binding to the sulfhydryl group (-SH) in the cell protoplasm through a colloid. When bacteria or fungi pass through the surface of the antibacterial component, the antibacterial component disrupts the metabolic action of the microorganisms. As a result, the microorganisms die within a few hours.

[0074] More preferably, the antibacterial polymer may be chitosan. Chitosan is the main component of the outer skin of insects or crustaceans and can be extracted from the shells of shellfish such as oysters, abalones, scallops, cockles, mussels, short-necked clams, clams, and bar clams, or the outer skin of insects.

[0075] Generally, chitin is the main substance forming the exoskeleton of crustaceans and is a mucopolysaccharide in which N-acetyl-D-glucosamine is bound by β-1,4. When chitin is deacetylated, it becomes chitosan. The above chitin and chitosan are not only non-toxic but also related to the synthesis and decomposition of organisms, so they are natural polymer cations that do not cause environmental pollution. Moreover, the possibility of using chitin and chitosan series derivatives as natural antibacterial agents is also emerging as part of the application of chitosan. In this regard, according to the report of Sudarshan et al., for ordinary Escherichia coli, chitosan lactate and chitosanhydroglutamate, etc., which are chitosan derivatives, are excellent antibacterial substances.

[0076] However, when the chitosan is mixed with the above-mentioned modified polyolefin resin, the adhesiveness of the adhesive layer will be reduced. Therefore, preferably, it is used in mixture with one or more catechol compounds.

[0077] The catechol compound refers to a compound having a structure in which two hydroxyl groups are connected in a benzene ring, and the hydroxyl groups react with the functional groups of the above-mentioned modified polyolefin resin, thereby enabling the adhesiveness and heat resistance to the adherend to be exhibited.

[0078] For example, the catechol compound may be one or more selected from the group consisting of L-Dopa, Pyrogallol, Dopamine, Pyrocatechol, norepinephrine, and 3,4-dihydroxycinnamic acid (DHCA), and preferably, it may be Dopamine.

[0079] The catechol compound may be the single compound or a compound in any form in which they exist in the molecular structure. For example, it may have a form in which a catechol organic compound is attached as a functional group to the main chain or side chain of a polymer.

[0080] The addition amounts of the antibacterial polymer and the catechol compound when mixed with the chitosan are not limited, and preferably contain 10 to 30 parts by weight and 1 to 10 parts by weight, respectively, based on 100 parts by weight of the modified polyolefin resin. If the addition amount of the component is less than the above range, the antibacterial property and adhesive property of the composition will be reduced. If it is greater than the above range, peeling of the sheet will occur due to increased processability and brittleness of the adhesive layer.

[0081] Furthermore, in order to further improve antibacterial property, adhesiveness and heat resistance as needed, the adhesive composition may further contain one or more cationic polymer particles.

[0082] The cationic polymer particles contain a plurality of cationic functional groups capable of forming chemical bonds with the above-mentioned modified polyolefin resin, antibacterial polymer, etc., and play an effect of increasing adhesiveness by improving the cohesion between components. And, the cationic polymer particles can further increase the antibacterial property of the packaging material by exhibiting the above-mentioned micro-movement effect.

[0083] The cationic polymer particles may contain a cationic polymer in which one or more cationic exchange functional groups selected from the group consisting of a sulfonic acid group, a carboxyl group, and a phosphate group are substituted. And, the cationic polymer may have a weight average molecular weight of 10,000 to 500,000. Specifically, it may be selected from a sulfonated tetrafluoroethylene-based polymer, a sulfonated polyimide (sPI), a sulfonated poly(arylene ether sulfone) (sPAES), a sulfonated polyetheretherketone (sPEEK), a sulfonated polyetherketone (sulfonated polyetherketone, sPEK), poly(vinylidene fluoride)-graft-poly(styrene sulfonic acid) (PVDFg-PSSA), and sulfonated poly(fluorenyl ether ketone).

[0084] The size of the cationic polymer particles is not limited, but preferably 10 μm or less, and more preferably has an average particle diameter of 1 μm to 5 μm.

[0085] Preferably, relative to 100 parts by weight of the modified polyolefin resin, 1 to 5 parts by weight of the cationic polymer particles are included. When the addition amount is within the above range, the effects of improving adhesiveness and antibacterial properties can be exerted, and thus it is preferred.

[0086] The thicknesses of the first adhesive layer 120 and the second adhesive layer 130 can be 5 μm to 1000 μm respectively. If the thicknesses of the first adhesive layer 120 and the second adhesive layer 130 are less than 5 μm, there will be a problem that the metal sheet layer 110 and the paper sheet layers 140 and 150 described later are likely to be peeled off due to insufficient adhesion. If the thicknesses of the first adhesive layer 120 and the second adhesive layer 130 are greater than 1000 μm, it will be difficult to achieve a multi-layer paper sheet 100 with uniform physical properties due to the generation of uneven air holes, and there will be a problem that it is difficult to achieve weight reduction of the multi-layer paper sheet 100.

[0087] The first paper sheet layer 140 and the second paper sheet layer 150 are respectively formed on the upper surfaces of the first adhesive layer 120 and the second adhesive layer 130 to form a multi-layer paper sheet.

[0088] The first paper sheet layer 140 and the second paper sheet layer 150 can be formed using paper sheets including deerskin paper, kraft paper, oleic acid paper, hanji paper, white cardboard, tissue paper, coated paper, embossed paper, porous paper, etc. Preferably, deerskin paper can be used.

[0089] The first paper sheet layer 140 and the second paper sheet layer 150 can be coated with ink on the upper surface to visualize patterns, patterns, characters, images, etc., and can visualize patterns, patterns, characters, images, etc. on the surface by common printing methods such as offset printing, intaglio printing or flexographic printing.

[0090] The thicknesses of the first paper sheet layer 140 and the second paper sheet layer 150 can be 5 μm to 1000 μm respectively. If the thicknesses of the first paper sheet layer 140 and the second paper sheet layer 150 are less than 5 μm, there will be a problem of reducing the durability and processability of the paper sheet. If the thicknesses of the first paper sheet layer 140 and the second paper sheet layer 150 are greater than 1000 μm, there will be a problem of reducing the adhesion and it will be difficult to achieve weight reduction of the multi-layer paper sheet.

[0091] Preferably, the thicknesses of the first paper sheet layer 140 and the second paper sheet layer 150 can be 10 μm to 100 μm respectively, and more preferably, they can be 30 μm to 80 μm.

[0092] In addition, the multi-layer paper sheet 100 of the present invention may further include a strength reinforcing layer (not shown) having a net structure between the first adhesive layer 120 and the first paper sheet layer 140 or between the second adhesive layer 130 and the second paper sheet layer 150.

[0093] The strength reinforcement layer serves to improve the dimensional stability of the multi-layer paper sheet. It can be formed by weaving fabric fibers such as glass fiber, carbon fiber, basalt fiber, and polyamide fiber into a net shape, or by introducing a fabric fabric with a net-like structure through knitting. A fabric fabric with a thickness of 0.1 μm to 500 μm can be introduced.

[0094] Furthermore, the multi-layer paper sheet 100 of the present invention can also be additionally constituted by including a polyethylene resin coating for the purpose of heat resistance, flame retardancy, blocking of cigarette smell, prevention of oxygen inflow, blocking of moisture, ensuring airtightness, etc., but is not limited thereto.

[0095] The multi-layer paper sheet 100 of the present invention can be manufactured by a general method for manufacturing a multi-layer paper sheet, in which an adhesive is applied to both surfaces of the metal sheet layer 110, the paper sheet is set on the upper surface of the adhesive, and then pressed, and then dried and cured.

[0096] Moreover, it can be manufactured by a method in which adhesive sheets are provided on both surfaces of the metal sheet layer 110, the paper sheets are overlapped on the upper surface of the adhesive sheets, heated at a temperature of 70 °C to 120 °C for 30 seconds to 60 seconds, and then dried and cured.

[0097] The cigarette butt collection bag 10 is joined by overlapping multi-layer paper sheets 100 to form a structure with an opening formed on one side for storing cigarette butts, and can have a general bag structure including a front part 11, a rear part 12, a joining part 13, and an opening part 14 (refer to Figure 1 ).

[0098] Furthermore, the cigarette butt collection bag 10 can be formed into the following structure: It can also include a lid part 15 protruding from the upper side of the front part 11 or the rear part 12. The opening part 14 is hermetically sealed by the lid part 15. The lid part 15 includes an adhesive layer on the upper side, and the lid part 15 can be folded down to the side of the front part 11 and adhered.

[0099] Looking closely at the structure of the cigarette butt collection bag 10 of the present invention, as Figure 2 shown, the cigarette butt collection bag 10a of a preferred embodiment of the present invention has a structure including a front part 11a, a rear part 12a, a joining part 13a, and an opening part 14a. The first bag structure 10a in the shape of a bag can be manufactured by joining a first multi-layer paper sheet with a quadrilateral structure and a second multi-layer paper sheet, and has a structure that can be conveniently opened to easily form the opening part 14a.

[0100] Specifically, the first bag structure 10a can be manufactured by overlapping and joining a first multi-layer paper sheet and a second multi-layer paper sheet in a quadrilateral shape. As Figure 3As shown, the first multi-layer paper sheet forming the front portion 11a has an equilateral trapezoidal shape with the following structure: the left and right side lengths of the non-parallel sides are the same, the length of the upper side is longer than the length of the lower side, and the lower side is the same as the lower side of the second multi-layer paper sheet described later. The first bag structure 10a can be manufactured by joining the first multi-layer paper sheet and the second multi-layer paper sheet. The second multi-layer paper sheet can be a multi-layer paper sheet having a rectangular shape with the lengths of the upper, lower, left, and right sides being the same, and an adhesive A can be applied to the edge portion for joining.

[0101] When manufacturing the first bag structure 10a including the front portion 11a and the rear portion 12a by overlapping and joining the first multi-layer paper sheet and the second multi-layer paper sheet having the above-described structure, joining portions 13a are formed on both sides and the lower side, and the upper side is open to form an opening portion 14a.

[0102] Therefore, the length of the upper side of the first multi-layer paper sheet forming the front portion 11a is longer than the length of the upper side of the second multi-layer paper sheet forming the rear portion 12a that is in contact therewith. When manufacturing the cigarette butt recycling bag 10, since no adhesive is applied to the upper side portions of the front portion 11a and the rear portion 12a, it naturally spreads open to form the opening portion 14a, thus having a structure in which the opening portion 14a can be conveniently formed by pressing the joining portions 13a on both sides.

[0103] Furthermore, the second multi-layer paper sheet forming the rear portion 12a can form a lid portion 15a by introducing a multi-layer paper sheet longer than the length of the first multi-layer paper sheet forming the front portion 11a, and the lid portion 15a is joined to one side of the front portion 11a by applying an adhesive to the upper end side of the second multi-layer paper sheet, thereby also forming a structure for airtightly sealing the opening portion 14a.

[0104] Or, as Figure 4 shown, the cigarette butt recycling bag 10b of a preferred embodiment of the present invention can be a second bag structure 10b having a structure including a front portion 11b, a rear portion 12b, joining portions 13b1, 13b2, an opening portion 14b, and a handle portion 16b. The second bag structure 10b can be manufactured by the following method: folding a multi-layer paper sheet having a quadrilateral structure on both sides in the length direction to form the front portion 11b and the rear portion 12b, applying adhesives to the two ends and the lower end of the front portion 11b in the folded state, and then forming the first joining portion 13b1 by joining the two ends and forming the second joining portion 13b2 by joining the lower end portion. Thus, it can have a structure that can be conveniently opened to easily form the opening portion 14b.

[0105] Therefore, the second bag structure 10b is configured such that when it is desired to store cigarette butts, one hand grasps both ends of the second bag structure 10b, and the other hand grasps the handle portion 16b and pulls, and by this method, it can be easily opened, thus easily forming the opening portion 14b.

[0106] Alternatively, as Figure 5 shown, the cigarette butt recycling bag 10c of a preferred embodiment of the present invention may be a third bag structure 10c having a structure including a front portion 11c, a rear portion 12c, a joining portion 13c, an opening portion 14c, a lid portion 15c, and a bending portion 17c. The cigarette butt recycling bag 10c can be formed in the following manner: by cutting a plurality of layers of paper sheets so that the lengths of the front portion 11c and the rear portion 12c are asymmetric, by extending and protruding the upper end of the rear portion 12c longer than the upper end of the front portion 11c in the length direction to form the lid portion 15c on the rear portion 12c, by pressing in from the outside to the inside of the bag in an "inverted V" shape to form the bending portion 17c on the front portion 11c and the rear portion 12c, and by joining both ends and the lower end of the front portion 11c and the rear portion 12c to form the joining portion 13c.

[0107] The third bag structure 10c having the above structure can be easily opened by a method of grasping the lid portion 15c with one hand and squeezing both side edges of the third bag structure 10c to bend the bending portion 17c, thus forming a structure for easily forming the opening portion 14c for storing cigarette butts.

[0108] Figure 6 A perspective view showing a cigarette butt recycling fourth bag structure 10d as an embodiment of a cigarette butt recycling packaging material according to still another preferred embodiment of the present invention.

[0109] As Figure 6 shown, the fourth bag structure 10d may have a structure including a front portion 11, a rear portion 12, a joining portion 13, an opening portion 14, and a triangular bottom surface portion 18. The triangular bottom surface portion 18 is formed by vertically forming a triangular front portion 11 formed at the lower ends of the front portion 11 and the rear portion 12 and the central region of the rear portion 12 to form a triangular surface and unfolding it. By cutting a plurality of layers of paper sheets, the front portion 11 and the rear portion 12 are folded along the vertical folding portion 19, and the bottom surface is unfolded by the triangular bottom surface portion 18, so as to be unfolded in a manner having the opening portion 14 and an appropriate capacity suitable for accommodating cigarette butts, thus enabling easy accommodation of cigarette butts.

[0110] Figure 7 A perspective view showing a cigarette butt recycling fifth bag structure 10e as an embodiment of a cigarette butt recycling packaging material according to still another preferred embodiment of the present invention.

[0111] As Figure 7As shown, the fifth bag structure 10e may have a structure including a front portion 11, a rear portion 12, side portions 20, joining portions 13 formed by joining the longitudinal edges on both sides of the side portions 20 to the front portion 11 and the rear portion 12 respectively, an opening portion 14, and triangular folding portions 21. The triangular folding portions 21 form vertical folding portions 19 along a vertical region at the center of the side portions 20. The central lower end portions of the side portions 20 in the region between the lower ends of the front portion 11 and the rear portion 12 are lifted upward to form a triangular dome and are folded. As the triangular dome unfolds, the triangular folding portions 21 unfold in the opposite direction. The front portion 11, the rear portion 12, and the side portions 20 are folded or unfolded through the vertical folding portions 19 and the triangular folding portions 21 by cutting multiple layers of paper sheets.

[0112] Figure 8 Fig. is a perspective view of a cigarette butt recycling cup 200 showing an example of a packaging material for cigarette butt recycling as another preferred embodiment of the present invention. Figure 9 For showing in Figure 8 Fig. is a view of the cigarette butt recycling cup 200 with a lid portion 205 attached.

[0113] As Figure 8 shown, the cigarette butt recycling cup 200 having the following structure can be manufactured by cutting the multiple layers of paper sheets. It includes: side portions 201 joined in a manner to form joining portions 203 and having an upside-down frustum shape; a circular opening portion 204 at the upper part formed through the side portions 201; and a circular bottom portion 202 for covering the bottom surface.

[0114] In this case, the diameter of the circular opening portion 204 may be 25 mm to 35 mm, the vertical height of the side portions 201 may be 65 mm to 75 mm, and the diameter of the bottom portion 202 may be 15 mm to 25 mm. Preferably, the diameter of the opening portion 204, the vertical height of the side portions 201, and the diameter of the bottom portion 202 may be 30 mm, 70 mm, and 20 mm.

[0115] Also, an inner region on the entrance side of the opening portion 204 of the cigarette butt recycling cup 200 may be formed as an adhesive region 206 coated with an adhesive layer with a release paper attached. Thus, after use, the entrance of the cup 200 can be sealed by removing the release paper and pressing the adhesive regions 206 against each other.

[0116] Differently, as Figure 9As shown, an upper end region of the cigarette butt collecting cup 200 facing the inside of the opening 204 is formed as an adhesive region 206 coated with an adhesive layer with a release paper attached thereto, and may further include a lid portion 205 formed to extend upward along a predetermined region on the entrance side of the opening 204. With the above structure, in the case of use being finished, after removing the release paper, making the opening 204 close tightly, and then covering it with the lid portion 205 to seal it with the adhesive, the entrance of the cup 200 can be sealed.

[0117] The cigarette butt collecting packaging material of the present invention as described above hermetically seals cigarette butts to prevent foul odors from being discharged to the outside, thereby not only keeping the environment clean but also ensuring sufficient flame retardancy to prevent fires.

[0118] Moreover, the cigarette butt collecting packaging material of the present invention can be conveniently opened to form an opening 14 by a method of pressing the upper edge portions on the left and right sides of a bag, which is an example of a packaging material, so that cigarette butts can be conveniently stored. And because of its thin thickness, multiple of them can be joined together and easily separated and used one by one, which is convenient for carrying. And the cigarette butt collecting cup 200 of the present invention has the shape of an ordinary paper cup, so it is convenient for storage and distribution. After use, the opening can be sealed through the adhesive region 206, which is convenient for post-use disposal.

[0119] In particular, the cigarette butt collecting packaging material of the present invention can prevent cigarette butts from being discarded randomly by improving the wrong smoking method of dropping or extinguishing the fire after smoking and then throwing away the cigarette butt, and can form a culture of safely packaging, neatly storing, and recycling cigarette butts, thereby contributing to the resource utilization of cigarette butts through reuse.

[0120] Among them, the cigarette butt collecting packaging material of the present invention contains a polymer with antibacterial properties and the like in a modified polyolefin resin as an adhesive composition, so that while ensuring excellent peel strength and adhesiveness, it has an antibacterial effect on bacteria remaining or breeding in saliva. Detailed Description of the Invention

[0122] Hereinafter, the present invention will be described in more detail through examples and comparative examples. However, the following examples are only an illustration of the preferred embodiments for explaining the present invention, and the present invention is not limited to the following examples.

[0123] The physical properties of the test pieces manufactured through the examples and comparative examples were measured in the following manner.

[0124] Air tightness

[0125] Using the multi-layer paper sheets manufactured through the following examples to make them have Figure 2A bag with the structure shown. Specifically, the first bag structure is manufactured by processing multiple layers of paper sheets in the following manner. The first multi-layer paper sheet forming the front portion 11a is processed into an isosceles trapezoid shape with the same left and right side lengths having non-parallel sides, the length of the upper side being longer than the length of the lower side, and the lower side being the same as the lower side of the second multi-layer paper sheet. The second multi-layer paper sheet is processed into a rectangular shape with the lengths of the upper and lower sides and the left and right sides being the same respectively.

[0126] The manufactured first bag structure is used to store cigarette butts. After covering the lid and sealing it, it is placed in a laboratory, and the emissions of aldehyde gases and benzene are measured. The cigarette butts are placed in the laboratory as a control group to measure the emissions together (unit: ppb).

[0127] Adhesiveness

[0128] To evaluate the adhesiveness of the manufactured multi-layer paper sheets, the adhesiveness is evaluated by T-peel strength measurement (adhesive force with a width of 15 mm). The peel strength measurement is carried out 5 times, and the average value is adopted. The peel strength (unit: g / 15 mm) is measured under the conditions of adjusting the peel speed (250 mm / minute), temperature (23 °C), and humidity (50% RH).

[0129] Antibacterial property

[0130] After cutting the test pieces manufactured by examples etc. into a size of 50 mm × 50 mm, they are placed in a place for culturing test strains. Specifically, the antibacterial activity is measured by the method according to JIS Z 2801:2006. Two types such as bacteria (Escherichia coli (ATCC 8739), Staphylococcus aureus (ATCC65380), and Pseudomonas aeruginosa (ATCC2 9027)) and fungi (Aspergillus niger (ATCC 9642) and Candida albicans (ATCC 90028)) are used as test strains for the test. The test bacteria are mixed according to different types and the viable count is measured 6 days after inoculation at room temperature (25 °C) to calculate the antibacterial rate.

[0131] Example 1

[0132] First, a modified polyolefin resin with a weight average molecular weight of 100,000 and an acid value of 8 mg KOH / g was prepared as an adhesive by reacting maleic anhydride with an ethylene-propylene copolymer having a propylene content of 65 weight percent. Then, an aluminum sheet with a thickness of 6 μm and a deerskin paper with a thickness of 30 μm were respectively prepared. After applying an adhesive with a thickness of 10 μm on both sides of the aluminum sheet, the deerskin paper was pressed onto the upper surface of the adhesive using a pressure roller for lamination, and a multi-layer paper sheet (total thickness 86 μm) was manufactured by curing the laminate.

[0133] Example 2

[0134] A test piece was manufactured in the same manner as in Example 1, except that when preparing the adhesive, 15 parts by weight of chitosan was added as an antibacterial polymer with respect to 100 parts by weight of the modified polyolefin resin.

[0135] Example 3

[0136] A test piece was manufactured in the same manner as in Example 2, except that when preparing the adhesive, 5 parts by weight of dopamine was added as a catechol compound with respect to 100 parts by weight of the modified polyolefin resin.

[0137] Example 4

[0138] A test piece was manufactured in the same manner as in Example 3, except that 3 parts by weight of sulfonated polyimide with an average particle size of 3 μm was added when preparing the adhesive.

[0139] Example 5

[0140] A test piece was manufactured in the same manner as in Example 4, except that when preparing the adhesive, 40 parts by weight of dopamine was added with respect to 100 parts by weight of the modified polyolefin resin.

[0141] Example 6

[0142] A test piece was manufactured in the same manner as in Example 4, except that 10 parts by weight of sulfonated polyimide with an average particle size of 3 μm was added when preparing the adhesive.

[0143] Comparative Example 1

[0144] A multi-layer paper sheet was manufactured in the same manner as in Example 1, except that a commercially available one-component polyurethane resin adhesive (Navimro Co., Ltd., Eco foam) was used.

[0145] Table 1

[0146]

[0147] As shown in Table 1, it can be confirmed that the test piece manufactured according to the present invention maintains airtightness to such an extent that the discharge amount of harmful gases is hardly measurable, and at the same time, the peel strength and antibacterial property are also excellent. Specifically, it can be confirmed that compared with Example 1 containing a modified polyolefin resin as an adhesive composition, Example 2 further adding chitosan significantly increases the antibacterial property while maintaining airtightness. It can be confirmed that compared with Example 2, the peel strength of Example 3 and Example 4 respectively adding dopamine and cationic particles is further improved. However, in the case of excessively adding dopamine or cationic particles in Example 5 and Example 6, it can be seen that the peel strength decreases compared with Example 4. This is because the said components are formed of polymers having a plurality of cationic functional groups, and as the number of chemical bonds formed by the said functional groups with other components increases, the brittleness is increased instead.
