Description
Technical Field
The present invention relates to water-resistant paper, and a packaging paper or container using the same.
Background
Paper packaging materials such as paper bags, cartons, paper cups and the like have been conventionally used for various purposes and purposes. In recent years, in order to replace plastic materials, there has been a growing trend in the use of "paper" using "wood" as a renewable resource as one of the materials having functions such as "recyclability" and "biodegradability", as a substitute for marine plastic waste, which is typified by microplastic.
One of the paper containers widely used in the past is paper cups used as containers for beverages, ice cream, yogurt, and the like. Paper cups are provided with water resistance by using a polyethylene film as a part of the raw material of paper. Such paper cups are obtained by bonding a polyethylene film, a polypropylene film, or the like, which is obtained by extruding a polyethylene resin, a polypropylene resin, or the like, which is melted by heat, into a film shape, to a paper base material. The polyethylene film functions as an adhesive by heat fusion under indirect heating such as a burner or hot air during paper cup molding, and the polyethylene film is present inside the paper cup, so that the paper substrate is not directly in contact with the contents, and is imparted with water repellency, moisture resistance, and strength.
However, the attached polyethylene film is not dissolved in the alkali solution used in the paper recycling process at the time of paper recycling, and thus needs to be physically removed, resulting in a decrease in recycling efficiency. In addition, marine pollution caused by outflow of plastic waste to the ocean becomes a worldwide problem. The following and the like are important topics worldwide: as an index of sustainable development targets (SDGs), a target of "preventing and greatly reducing all kinds of marine pollution including marine waste and eutrophication, particularly pollution caused by land activities, etc." has been proposed by 2025, and an agreement of enhanced cooperation has been achieved also at a peak (major national head office). Accordingly, there is a need for polyethylene film alternatives that can be applied to these uses without reducing the paper recycling efficiency.
On the other hand, as a substance that functions as an adhesive at the time of molding of bags, boxes, paper cups, and the like, an aqueous heat sealing agent is known. For example, patent document 1 discloses the following: an aqueous dispersion of an olefin- α, β -unsaturated carboxylic acid copolymer neutralized with ammonia or an amine and an olefin-based thermoplastic resin other than the above-mentioned copolymer are mixed and dispersed in a specific ratio, and can be used as a heat sealing agent.
Patent document 2 discloses the following: an aqueous dispersion containing a polyolefin resin comprising an unsaturated carboxylic acid unit, a vinyl hydrocarbon, and an acrylic acid ester or methacrylic acid ester, a natural wax, and an aqueous medium in a specific ratio can be used as a heat sealing agent.
However, these documents disclose only so-called heat-sealing properties such as heat-sealing strength and blocking resistance, but do not describe any water resistance, moisture resistance, strength and recyclability that are desired as alternatives to polyethylene films.

[ Heat-sealable coating ]
In the water-resistant paper, the heat-sealable coating layer is provided at an appropriate portion on the paper base material according to the final packaging material, the shape of the container, and the use, but for example, in the paper base material, it is more preferable to provide the heat-sealable coating layer on the surface opposite to the surface on which the water-resistant coating layer is provided.
The water-resistant paper of the present invention has a heat-sealing function by the coating layer having heat-sealability, and has improved water resistance. Further, by attaching the heat-sealed portion, various packaging materials such as bags and boxes can be produced according to the application, and the workability improves.
The heat-sealable coating layer may be formed by a known heat-sealable coating agent, but in order to improve water resistance, an aqueous heat-sealing agent (HS) containing an aqueous solvent, an olefin- α, β -unsaturated carboxylic acid copolymer, and a wax (W1) is preferably used. The aqueous heat sealing agent (HS) can be used as a heat sealing agent for manufacturing paper containers and the like, and the coating portion other than the sealing (bonding) portion also functions as a coating agent for imparting water repellency to paper.
< Water-based Heat Sealant (HS) >)
The aqueous Heat Sealer (HS) contains at least an aqueous solvent, an olefin-alpha, beta unsaturated carboxylic acid copolymer, and a wax (W1).
(aqueous solvent)
As the aqueous solvent used for the aqueous heat sealing agent HS, water, a water-soluble organic solvent dissolved in water, or the like can be used. As the water, pure water such as ion-exchanged water, ultrafiltration water, reverse osmosis water, distilled water, or ultrapure water can be used. The water is preferably sterilized by ultraviolet irradiation, hydrogen peroxide addition, or the like, because it can prevent the generation of mold or bacteria when the aqueous pigment dispersion is stored for a long period of time, or when an ink using the pigment dispersion is used.
Examples of the water-soluble organic solvent include glycols such as ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, propylene glycol, polyethylene glycol, and polypropylene glycol; diols such as butanediol, pentanediol, and hexanediol; glycol esters such as propylene glycol laurate; diethylene glycol ethers such as diethylene glycol monoethyl ether, diethylene glycol monobutyl ether, diethylene glycol monohexyl ether, and carbitol; glycol ethers such as cellosolve including propylene glycol ether, dipropylene glycol ether and triethylene glycol ether; alcohols such as methanol, ethanol, isopropanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, and pentanol; and various other solvents known as aqueous organic solvents, such as lactones, e.g., sulfolane, ester, ketone, and γ -butyrolactone, lactams, e.g., N- (2-hydroxyethyl) pyrrolidone, and glycerin and polyoxyalkylene adducts thereof. These aqueous organic solvents may be used singly or in combination of two or more. Among them, water is most preferable.
(olefin-alpha, beta unsaturated carboxylic acid copolymer)
Examples of the olefin- α, β -unsaturated carboxylic acid copolymer used in the aqueous heat-sealing agent HS include copolymers of an olefin and at least 1 monomer selected from the group consisting of α, β -unsaturated carboxylic acids, metal salts of α, β -unsaturated carboxylic acids, and esters of α, β -unsaturated carboxylic acids. Specifically, examples of the metal salt of an α, β -unsaturated carboxylic acid, an α, β -unsaturated carboxylic acid or a copolymer of an α, β -unsaturated carboxylic acid ester and an olefin include an olefin- α, β -unsaturated carboxylic acid copolymer, an ethylene-acrylic acid ester copolymer, an ethylene-methacrylic acid ester copolymer, an ethylene-acrylic acid-maleic anhydride copolymer, an ethylene-acrylic acid ester-maleic anhydride copolymer, an ethylene-methacrylic acid ester-maleic anhydride copolymer, and metal salts thereof. These copolymers may be used alone or in a mixture of 2 or more.
Among them, olefin- α, β unsaturated carboxylic acid copolymers are preferable. Examples of the olefin- α, β -unsaturated carboxylic acid copolymer include random copolymers or block copolymers of ethylene and α, β -unsaturated carboxylic acid.
Examples of the olefin include ethylene, propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, 1-decene, 4-methyl-1-pentene, butadiene, dicyclopentadiene, and 5-ethylidene-2-norbornene. Among them, ethylene is preferable.
Examples of the α, β -unsaturated carboxylic acid include acrylic acid, methacrylic acid, crotonic acid, maleic acid, fumaric acid, itaconic acid, and the like. Among these, acrylic acid and methacrylic acid are suitably used. These α, β -unsaturated carboxylic acids may be used singly or in combination of 2 or more.
The α, β -unsaturated carboxylic acid esters are not particularly limited, and known alkyl esters, hydroxyalkyl esters, alkoxyalkyl esters, and the like of acrylic acid or methacrylic acid can be used. For example, specific examples thereof include acrylic esters such as methyl acrylate, ethyl acrylate, isopropyl acrylate, n-propyl acrylate, n-butyl acrylate, isobutyl acrylate, 2-ethylhexyl acrylate, isooctyl acrylate, n-octyl acrylate, 2-hydroxyethyl acrylate, 2-methoxyethyl acrylate, methyl methacrylate, ethyl methacrylate, isopropyl methacrylate, n-propyl methacrylate, n-butyl methacrylate, isobutyl methacrylate, n-hexyl methacrylate, 2-ethylhexyl methacrylate, n-lauryl methacrylate, 2-hydroxyethyl methacrylate, 2-ethoxyethyl methacrylate, and the like. These may be used in 1 kind or in combination of 2 or more kinds.
The method for producing the olefin- α, β unsaturated carboxylic acid copolymer can be obtained by a known method, for example, radical copolymerization at high temperature and high pressure.
The content of the α, β -unsaturated carboxylic acid in the above-mentioned olefin- α, β -unsaturated carboxylic acid copolymer is desirably 8 to 24% by weight, preferably 18 to 23% by weight. When the content of the α, β -unsaturated carboxylic acid is less than 8% by weight, the dispersibility in an aqueous dispersion medium is poor due to the nonpolar nature derived from the ethylene unit, and there is a concern that it is difficult to obtain an excellent aqueous dispersion of the olefin- α, β -unsaturated carboxylic acid copolymer resin. In addition, when the content of α, β -unsaturated carboxylic acid exceeds 24% by weight, there is a concern that the blocking resistance of the obtained coating film may be deteriorated.
The olefin- α, β unsaturated carboxylic acid copolymer used in the aqueous heat sealer HS is used in the form of an aqueous dispersion dispersed in an aqueous solvent. The method of dispersing in the aqueous solvent is not particularly limited and may be carried out by a known method. Examples of the method include a method of dispersing an olefin- α, β unsaturated carboxylic acid copolymer in an aqueous solvent by emulsifying the copolymer with a surfactant, and a method of neutralizing the copolymer with a basic compound and dispersing the neutralized copolymer in an aqueous solvent.
As the surfactant used in the emulsification, various known anionic, cationic, nonionic surfactants or various water-soluble polymers can be used in combination as appropriate.
Examples of the basic compound used in the neutralization include organic amines such as ammonia, methylamine, ethylamine, diethylamine, dimethylethanolamine, diethanolamine, and triethanolamine, and alkali metal hydroxides such as sodium hydroxide, potassium hydroxide, and lithium hydroxide. These basic compounds may be used singly or in combination of 2 or more.
The degree of neutralization by the basic compound may be any degree as long as the olefin- α, β -unsaturated carboxylic acid copolymer is stably present in the aqueous solvent. For example, the carboxyl group of the copolymer may be desirably 30 to 100 mol%, more preferably 40 to 90 mol%.
As the above-mentioned dispersing method, for example, as a dispersing device using a medium, a paint stirrer, a ball MILL, an attritor, a basket MILL, a sand MILL, a DYNO-MILL (DYNO-MILL), a DISPERMAT dispersing machine, an SC MILL, a nail crusher, a stirring MILL, etc. may be used, and dispersion may be performed using an ultrasonic homogenizer, a high-pressure homogenizer, a nano-zer crusher, a dissolver, a disperser, a high-speed impeller dispersing machine, etc. as a dispersing device not using a medium.
The solid content of the aqueous dispersion of the olefin- α, β -unsaturated carboxylic acid copolymer used in the present invention is not particularly limited, and may be appropriately determined depending on the viscosity desired when it is applied as a heat sealer, the drying condition after the application of the heat sealer, the film thickness of the coating film, and the like. Generally, the present invention is generally applied in a range of 10 to 40 mass% in solid content concentration.
(wax (W1) for aqueous Heat Sealant (HS))
The wax (W1) is added to the aqueous Heat Sealer (HS), whereby blocking resistance can be maintained. Examples of the wax (W1) include waxes such as fatty acid amide wax, carnauba wax, polyolefin wax, paraffin wax, fischer-tropsch wax, beeswax, microcrystalline wax, oxidized polyethylene wax, and amide wax, coconut oil fatty acid, and soybean oil fatty acid.

Specific examples of the fatty acid amide wax include pelargonic acid amide, capric acid amide, undecanoic acid amide, lauric acid amide, tridecanoic acid amide, myristic acid amide, pentadecanoic acid amide, palmitic acid amide, margaric acid amide, stearic acid amide, nonadecanoic acid amide, arachic acid amide, behenic acid amide, lignoceric acid amide, oleic acid amide, hexadecenoic acid amide (Japanese, melissic acid amide), linoleic acid amide, linolenic acid amide, a mixture thereof, and animal and vegetable fat fatty acid amide.
Specific examples of the carnauba WAX include MICROKLEAR 418 (manufactured by MicroPowrers, inc.), refined carnauba WAX No. 1 powder (NIPPON WAX Co., ltd.), and the like.
The amount of the wax (W1) to be blended is preferably 1.5 to 20% by mass based on 100% by mass of the total amount of the solid components of the aqueous heat-sealing agent (HS). If the total amount of the wax (W1) is 3 mass% or more relative to the total 100% of the solid content of the aqueous heat-sealing agent (HS), the blocking resistance tends to be maintained, and if the total amount of the wax (W1) is 15 mass% or less relative to the total 100% of the solid content of the aqueous heat-sealing agent (HS), the heat-sealing property tends to be maintained.
In the wax (W1), the fatty acid amide wax and the carnauba wax are used in combination, and the blocking resistance is further improved, more preferably. In the case of the combination, the ratio thereof is not particularly limited, and preferably, a fatty acid amide wax: carnauba wax = 1:1 to 1: the range of 10 is preferred, and the range of 1:1 to 1:5 is more preferred.
The wax (W1) may be directly added to the aqueous dispersion of the olefin- α, β -unsaturated carboxylic acid copolymer and mixed and dispersed, or may be simultaneously added to and mixed and dispersed in dispersing the olefin- α, β -unsaturated carboxylic acid copolymer in an aqueous solvent. The dispersion method may be appropriately used as the method used in the above-mentioned dispersion method of the above-mentioned olefin- α, β -unsaturated carboxylic acid copolymer in an aqueous solvent.
When a plurality of waxes (W1) are used in combination, the plurality of waxes (W1) may be added simultaneously or may be added in a plurality of steps. For example, an aqueous Heat Sealant (HS) may be obtained by: after the first wax (W1) is added when the olefin- α, β unsaturated carboxylic acid copolymer is dispersed in an aqueous solvent, the second wax (W1) is further added to the aqueous dispersion of the obtained first wax (W1) and the olefin- α, β unsaturated carboxylic acid copolymer.
The aqueous heat sealing agent (HS) may contain additives such as silica, alumina, defoaming agent, viscosity modifier, leveling agent, thickener, preservative, antimicrobial agent, rust inhibitor, antioxidant, silicone oil, and the like, in addition to the above components, within a range that does not hinder the object of the present invention.
In addition, in the aqueous heat sealing agent (HS), in order to prevent foaming when coating using various coating machines, a polymer-based defoaming agent, a silicon-based defoaming agent, and a fluorine-based defoaming agent are preferably used. As these antifoaming agents, any of an emulsion dispersion type, a soluble type, and the like can be used. Among them, polymer-based antifoaming agents are preferable. The amount of the defoaming agent is preferably 0.005 to 0.1% by weight based on the total amount of the aqueous heat-sealing agent.
The aqueous heat sealing agent (HS) can be used as a heat sealing agent in the production of paper packaging materials such as bags and boxes, and as a coating agent for imparting water repellency to paper, the coating portion other than the sealing (bonding) portion is used.
< method for producing Heat-sealable coating layer >
The heat-sealable coating is provided by coating on, for example, a paper substrate using a known heat-seal coating or heat-seal (HS). As a coating method at the time of coating, a known method can be used. For example, roll coaters, gravure coaters, flexible coaters, air knife coaters, doctor blade coaters, air knife coaters, extrusion coaters, impregnating coaters, transfer roll coaters, kiss coaters, curtain coaters, cast coaters, spray coaters, die coaters, offset printers, screen printers, and the like can be used. In addition, a drying step may be provided by an oven or the like after the application.
In the case of using an aqueous heat sealing agent (HS), the film thickness of the solid component after coating may be a desired film thickness, for example, in the case of using it in a paper container for food, if it is 2 to 12g/m 2 In the above range, water resistance and heat sealability can be sufficiently obtained. Of these, more preferably 5 to 10g/m 2 Is not limited in terms of the range of (a).
The aqueous heat sealing agent (HS) has a function as an adhesive for bonding 2 portions of the paper substrate coated with the aqueous heat sealing agent in a superimposed state. Specifically, the aqueous heat sealing agent of the present invention is applied to at least one (or two) of 2 portions of the paper base material, and then softened by heating. The aqueous heat sealing agent is easily softened by heating with a burner or hot air, and can bond papers or papers with other raw materials, and thereafter, the bonding portion is solidified by cooling, whereby the papers or papers and other raw materials can be firmly sealed.
As the heating method, conventionally known means such as a heat source such as a burner, hot air, electric heat, infrared rays, and electron beams can be used, and specifically, a method of heating with a burner or hot air, a heat fusion sealing method according to a molded shape, an ultrasonic sealing method, or a high-frequency sealing method is preferable. The heating temperature in this case is preferably 200 to 500℃and the heating time is preferably 0.1 to 3 seconds.
In addition, the aqueous heat sealing agent (HS) is easily softened by heating without contact, and the heat sealing function is continued for a certain period of time even when it is separated from the heat source, in addition to the method of melting by contact with a direct heat source such as a heat sealing rod. In the case where the base material is paper, there is a possibility that the paper burns when in contact with a direct heat source, but the heat sealing agent of the present invention exhibits a heat sealing function under non-contact heating and the function is continued, and therefore, is particularly useful as a heat sealing agent for industrial production of paper containers, which requires a high line speed.
The aqueous heat sealing agent (HS) is applied and the applied portion is softened by heating, and then the applied portion is pressure-bonded in a state of being overlapped with another portion, whereby the aqueous heat sealing agent can be used as a heat sealing agent. The pressure bonding method is not particularly limited, and may be performed by a hot plate method, ultrasonic sealing, or high-frequency sealing. Of course, the aqueous heat sealing agent (HS) may be used as a paper coating agent without heat sealing. In this case, the film is coated to have a desired film thickness by the coating method, and then dried by a drying method such as heat drying or normal temperature drying.

< evaluation item >
(Water resistance)
Tap water was collected into a dropper, and 0.1ml of tap water was added dropwise to the surface of the coated paper test piece for evaluation, which was provided with a water-resistant coating.
After tap water was added dropwise, tap water was wiped off at 25℃for each of 1 hour, 4 hours, 5 hours and 8 hours, and the front and back surfaces were visually evaluated according to the following evaluation criteria.
O: there was no trace of dripping on the surface, swelling by water, or penetration to the back.

(blocking resistance)
The coated surface of the prepared water-resistant paper was overlapped with the coated surface, a load of 10kgf/cm2 was applied thereto, the water-resistant paper was taken out after 48 hours at 40℃and the adhesion between the coated surface and the non-coated surface was visually evaluated in the following 4 stages.
(evaluation criterion)
And (3) the following materials: no blocking was observed at all.

Delta: blocking was partially observed.
X: blocking was observed across the entire face.
(sliding angle)
The coated surface of the produced water-resistant paper was overlapped with the coated surface, and the inclination angle at which the coated paper began to slide was measured as the sliding angle by the inclination method.
