(1) (1) 200405913 发明. Description of the invention [Technical field to which the invention belongs] The present invention relates to a laminated material for packaging and a packaging body using the laminated material, and in particular to a package having a deoxidizer, a desiccant, a dehumidifier, etc. A laminated material for packaging a functional article and a packaging body using the laminated material.

In recent years, in order to prevent the spoilage, deterioration, and deterioration of processed foods, deoxidizers and desiccants have been widely used. This deoxidizer is a powdery or granular deoxidizer (oxygen absorbent) containing a breathable pouch. In addition, biscuits such as pancakes, seaweed, etc., where the price of products such as moisture will decrease due to moisture absorption, are similarly packaged with a desiccant such as silicone in a sachet. That is, the packaging body of these functional agents is the one that absorbs the air, moisture, oxygen, etc. inside the packaging body (bag) of the article, and is packaged using air-permeable packaging materials. In addition, air-permeable packaging materials are also used for fragrances, insect repellents, and the like that function from the active ingredients generated by the packaging agent through the packaging material. In addition, recently, adsorbents containing odors of powders such as activated carbon and charcoal are packaged in a sheet form having a large area, and are often used in hospital beds and the like. In addition, in view of the expansion of trade in electronics, electrical appliances, medical equipment, and precision equipment, in order to prevent moisture, oxidation, and quality stability of these products, large-scale packaging desiccants and deoxidizers are generally used.

(2) (2) 200405913 These air-permeable packaging materials must be packaged without leakage of powder, etc., and the heat-seal of the packaging must be strong enough to be suitable for packaging, that is, sealed High strength, stable sealing strength, high-speed continuous packaging and other conditions. In the case where the content is a deliquescent hygroscopic agent, it must also be waterproof. In particular, there is a need for a packaging material that can be applied to small packages such as deoxidizers and hygroscopic agents to large packages such as activated carbon and charcoal. Also, it is necessary to have packaging materials that have moderate water resistance, moisture permeability, and air permeability. The air-permeable packaging materials that can be used for such packaging include the following technology (1): Japanese Patent No. 2 9 3 6 6 7 This patent discloses a paper layer and a sheath-core composite fiber. Non-woven layer, and composite sheet made of composite fiber with the melting point of the sheath component of the non-woven fabric below 160 ° C and the melting point of the core component higher than that of the sheath component by 30 ° C or more. This composite sheet is made by melting and gluing a sheath component of a non-woven fabric with paper to achieve an interlayer bonding strength of 400 g / 15 mm or more. However, this composite sheet is made of a sheath-core composite fiber nonwoven fabric. In the manufacture of nonwoven fabrics, it is difficult to manufacture the fabric stably due to the difference in melt viscosity and compatibility of the sheath-core resin. In addition, there is a problem that it is difficult to accelerate the speed of packaging due to insufficient sealing properties. In addition, laminated and heat-sealed systems can be used as the low-melting resin of the sheath component resin of the composite fiber. In addition to the temperature conditions at the time of lamination, there are limits, and the sealability when heat-sealed has its limits. -6-4? 200405913

This publication discloses a plate-shaped oxygen absorbent packaging material made of polyethylene resin-embedded non-woven fabric (inlay) for the inner layer, absorbent paper for the middle layer, and paperboard for the outer layer. However, this kind of packaging material is to make it ventilating, and it is necessary to perforate a plurality of fine holes with a diameter of about 0.5 mm in the panel in advance, so that the manufacturing process becomes complicated. In addition, the adhesiveness between the insert layer and the paper layer is low. As shown in the examples, it is essentially necessary to use a sandwitch lamination of polyethylene resin, and it is conceivable that it is difficult to control the moisture permeability. Ventilation problems. As for the air-permeable material, a microporous film layer obtained by extending an inorganic rhenium-containing filler polyethylene film is known. However, since this microporous thin film layer has insufficient strength, it is generally used as a laminated material together with a nonwoven fabric.

A wet sheet, and clothing or an absorbent article using the laminate. Among these, when the laminated body which is heat-melted and glued as described above is used as an absorbent article for disposable diapers such as disposable clothes, the heat-sealability and heat-seal strength are not problematic. In other words, the laminated material using a microporous polyolefin-based resin film in the future is intended to improve the strength and heat-sealability of the microporous polyolefin-based resin film by laminating with a nonwoven fabric. Therefore, as long as air permeability and adhesiveness can be ensured, there is no problem in the lamination method in the case of using an adhesive or the case of relying on hot-melt bonding. However, if a microporous polyolefin resin film is used as a substitute for paper and a functional agent such as a deoxidizing agent or a desiccant is used for packaging, it will not only have air permeability and moisture permeability, but also prevent leakage of fine powder. Sealability and seal strength will become very important. The reason is that the packages of these functional agents are mainly packaged with food for the purpose of preventing oxidation and moisture absorption of food. Therefore, if a deoxidizer or a desiccant comes into contact with or is mixed with food, the safety of the food may be a problem. Therefore, in order to prevent leakage of the deoxidizer or drying, it must be heat-sealed surely and stably. In general, it is expected that such a reliable heat-sealing and packaging body can be packaged in an efficient manner. In this regard, there is a case where the existing double-layer laminated material cannot completely correspond to the -9-(6) 200405913. The object of the present invention is to provide a waterproof, moderately breathable, breathable, easy to manufacture, without the problems of air fall or odor caused by the adhesive, excellent in strength, and when performing articles with functionalities such as deoxidizers, etc. It is not easy to leak the packaged items when they are packaged, and they have good productivity. They can be used for high-speed continuous packaging of packaging products and packaging bodies using the laminated materials. In addition, as for air-permeable packaging materials, the following techniques are well known (9) The mixed pulp paper made of pulp and hot-melt adhesive fibers (high-density polyvinylene, etc.) There is no contamination of the heat-seal bar (paper roll ΐ roll) during automatic packaging and the thickness (1 0) of paper and microporous sealant, which does not have good printability on the surface. The laminated material of the sealant film has no problem in terms of sealing strength, and it is difficult to perform the laminating operation under the condition of ensuring the air permeability of the paper. In addition, it is known that there is a multilayer material using paper and non-woven fabrics, but those that have a tree laminated on the outer layer because of the need to ensure water resistance and sealing, or a laminate of paper and non-woven fabrics using an extrusion film of polyethylene resin, In terms of its purpose and structure, it is different from related laminated materials for air-permeable packaging.

The packaging agent is not easy to leak during packaging, and has excellent sealing properties (sealing and strength, especially hot tack), good productivity, and a laminated material for air-permeable packaging capable of high-speed continuous packaging and the use of the packaging material. Package.

Packaging of the agent. The laminated material for packaging of the present invention can be realized by appropriately using the existing materials or manufacturing methods, but specific materials or manufacturing methods will be described in detail below. [Air-permeable heat-resistant fiber material layer having heat resistance of 150 ° C or higher] In the present invention, the air-permeable heat-resistant fiber material layer having heat resistance of 150 ° C or higher belongs to a general thermoplastic resin. Fibers can be exemplified by: a single polymer of propylene; a random copolymer of propylene and 5% by mass or less of ethylene, butadiene-13- (10) (10) 200405913 ene-1 and other monomers, etc. Polypropylene; polyethylene terephthalate, polybutylene terephthalate, cyclobutylene terephthalate, etc .; and the main component units based on these Copolyesters copolymerized with other ingredients, and polyester weaves of these mixed polyesters, nylon 6 (polycaprolactam), nylon 6, 6 (polyhexamethylene diamine), nylon 6, 10 (polysebacamide), nylon 11 (polyundecane), nylon 7 (poly-w-aminoheptanoic acid), nylon 9 (poly-w-aminononanoic acid), nylon 1 2 (polylauramine) and other polyamide fibers. Examples of other fibrous materials other than thermoplastic resin fibers include non-melting fibrous materials such as wood pulp, linden tree, Huang Ruixiang, and rayon. These breathable heat-resistant fiber material layers are made of heat-resistant fiber material. Woven, non-woven, woven, paper, etc. are not particularly limited, but they are preferred because of their strength, elongation, flexibility, and cheapness. It is a spunbond fabric or a nonwoven fabric made of the aforementioned thermoplastic resin. The fiber diameter of the spunbond non-woven fabric used in the breathable heat-resistant fiber material layer is not particularly limited, but it is usually 5 to 6 0 // m, preferably 10 to 4 0 // m, in units. The area weight is usually 10 to 10 Og / m2, preferably 15 to 80 g / m2. If it is less than 10 g / m 2, the effect of preventing edge breaks during heat sealing is insufficient. If it is more than 100 g / m 2, the productivity will be lowered when laminated by thermal lamination. Not appropriate. That is, if a laminated material is formed, the polyethylene resin spunbond nonwoven fabric layer will melt and invade the heat-resistant cellulose -14- (11) (11) 200405913 and it will be thermally melted with the microporous film layer For gluing, considering the required sealing strength and productivity during lamination, the heat resistant fiber material layer can be selected. For the manufacture of spunbond nonwoven fabrics for air-permeable heat-resistant fiber material layers, for example, these resins can be melt-extruded from an extruder, spun from a spinning nozzle, and the spun fibers can be used as Air suction device (air sucker) and other air pulling device to extract, if necessary, open the fibers' together with the air flow in a web capture device such as a mesh conveyor belt 'capture' to heat the air, heating if necessary A heating device such as a roller performs a well-known step such as partial hot-melt gluing. Herein, when such a spunbond fabric nonwoven fabric is manufactured, it may be laminated in-line with other nonwoven fabric layers and the like. [Polyethylene-based spunbond fabric nonwoven layer] The polyethylene-based spunbond fabric nonwoven layer in the present invention is not particularly limited, but may be exemplified by a separate polymer with ethylene, ethylene and α-olefin, Copolymers of copolymerizable monomers such as unsaturated carboxylic acids or their derivatives, cyclic olefins, and high-pressure branched low-density polyethylene. Among them, preferred are α-burned hydrocarbons having a carbon number of 3 to 10, such as ethylene and propylene, butene-1, 4-methyl-heptene-1, hexane-1, smolder-1, etc. Copolymer (L·LD PP E). These polyethylene resins can be polymerized using a (co) polymer polymerized with Ziegler's catalyst such as titanium, or (co) polymerized using a metallocene catalyst. Things. -15- (12) (12) 200405913 In particular, the density is preferably 880 to 9 6 Okg / m3, more preferably 900 to 9 50 kg / m3, and the melting point is 80 to 1 40 ° C, which is more than The aforementioned ethylene in the range of 90 to 130 ° C with a MFR melt flow rate in the range of 5 to 60 g / 10 minutes, preferably 10 to 50 g / 10 minutes An α-olefin copolymer is useful due to its spinnability, melting point, and strength. The fiber diameter of the non-woven layer of the polyethylene resin spunbond fabric is usually 5 to 60 // m, preferably 10 to 40 // m, and the unit weight thereof is 10 to 200 g / ni2, preferably 1 5 to 15 Og / m2, more preferably 20 to 100 g / m2. For the production of the spunbond fabric nonwoven for the polyethylene-based spunbond fabric nonwoven layer, the manufacturing steps of the spunbond fabric nonwoven for the breathable heat-resistant fiber material layer described above can be used. [Microporous film layer] The microporous film layer in the present invention is not particularly limited, as long as it is a general polyethylene resin microporous film layer, especially a polyethylene resin microporous film layer , Its manufacturing method is arbitrary, and a well-known film can be used. This polyolefin-based resin microporous film layer is made of, for example, a film made of a polyolefin-based resin containing an inorganic filler, an organic filler, a plasticizer, or the like, using a solvent to dissolve the filler or the plasticizer. A method of a microporous structure is a film obtained by extending a film made of a polyolefin-based resin containing an inorganic filler or an organic filler in at least one axis. -16- (13) (13) 200405913 Among these, a film made by extending a film containing an inorganic resin filler or an organic resin with a polyolefin resin and extending it in one axis is preferable. The polyolefin-based resin used in the present invention is a high-density polyethylene, a medium-density polyethylene, an ethylene-α-olefin copolymer, a high-pressure paper density branched polyethylene, a copolymer of polypropylene, propylene, and other olefins, or A mixture of these polyolefins. Among these, a polyethylene resin is preferable. As for the density of this polyethylene resin, it is usually 880 to 96 kg / m3, preferably 900 to 950 kg / m3, and the melt flow rate (MFR) [according to JISK 7 2 1 0, measurement temperature: 190 ° C ', measurement load: 21 · 18N], it is usually from 0.01 to 10 g / 10 minutes, and preferably from 0.02 to 5 g / 10 minutes. An inorganic filler that can be contained in a polyethylene resin. An inorganic or organic filler can be used. For example, calcium carbonate, talc, clay, kaolin, silica, diatomite, magnesium carbonate, and barium carbonate can be used. , Barium sulfate, calcium sulfate, calcium sulfite, calcium hydroxide, magnesium hydroxide, aluminum hydroxide, zinc oxide, calcium oxide, magnesium oxide, titanium oxide, mica, alumina, zeolite, glass powder, etc. , Wood powder, cellulose powder, high melting point resin powder, cross-linked resin powder and other organic fillers. The average diameter of these fillers is usually less than 3 0 // m, preferably in the range of 0 · 2 to 1 0 // m. Here, if the particle diameter is too small, the dispersibility and moldability are better, and if it is too large, the fineness of the stretched film is poor, and the powder leakage resistance may be lowered. These may contain plural kinds as necessary. In addition, in order to improve the dispersibility of polyolefin resins, these fillers can be used for surface treatment with fatty acids or fatty acid metal salts in order to extend the film. For this reason, the content of the inorganic filler is from 20 to 400 parts by mass, and preferably from 40 to 300 parts by mass, based on 100 parts by mass of the polyolefin resin. Here, if the content of the fluorene filler is less than 20 parts by mass, the formation of microporosity in the case of stretching the film is insufficient, and the moisture permeability cannot be sufficiently ensured. In addition, if it exceeds 400 parts by mass, the kneading property, dispersibility, and film-forming properties of the film are reduced, and the strength may be reduced. Furthermore, other films, elastomers, and various additives commonly used in polyolefin resin films containing fillers can be blended as necessary. Examples include ethylene-propylene copolymer elastomers, liquid or solid hydrocarbon resins, liquid polybutadiene containing active hydrogen, plasticizers, free radical initiators, ultraviolet absorbers, higher fatty acids, their esters, Slip agents, colorants, flame retardants, and the like of amines and their metal salts. Polyolefin resins can be pelletized using a Banbury mixer (Bubm bui r y m i X e r), a kneading extruder, etc. together with a given amount of filler and various additives. This pellet was used to form a film using a T-die extrusion molding machine and an inflation molding machine. The produced film will be stretched at least 1 axis in the order of 1.5 to 10 times. The extension operation can be performed in multiple stages, or it can be extended in a biaxial direction. The film stretching operation is carried out from a temperature lower than the melting point of the polyolefin resin by 100 ° C to a temperature lower than the melting point by 20 ° C. As a result of this stretching operation, the strength of the film can be improved, and the shape of -18- (15) (15) 200405913 becomes microporous. Since the stretched film is heat-treated, the dimensional accuracy of the film can be improved. Furthermore, surface treatments such as corona treatment, flame treatment, etc., which can improve the adhesion of the film, can also be applied to the build-up layer of the film. The film thickness of the polyolefin-based resin microporous film layer thus obtained is in the range of 10 to 200 # m, and preferably in the range of 15 to 100 / m. The moisture permeability of this film is usually 100 g / m2 · 2 or more for 4 hours, preferably 500 g / m 2 · 2 or more. The measurement method will be described later. When these characteristics are met, it is preferable to have fine pores having an average diameter of 0.1 to 50 // m and a void ratio of 10 to 80%. The thin film of the polyolefin resin microporous film layer is thick, and the moisture permeability can be determined according to the characteristics of the packaged product used in the laminated material of the present invention, and its application. Such a polyolefin-based resin microporous film layer itself is well known, and various films can be easily obtained from the market. For example, polyethylene stretched moisture-permeable films containing inorganic fillers can be exemplified by: "Bronam PU 3 5" manufactured by Tokuyama Co., Ltd., and "Breststrom" manufactured by Nitto Denko Corporation "," Esperval "made by Mitsui Chemicals Corporation. "Air-permeable material" As far as the air-permeable material of the present invention is concerned, it is preferably air-permeable material that can be used for thermal lamination of microporous films. Furthermore, in order to reduce edge fracture during heat-sealing and to serve as a micro For the function of porous film, what does it have? Since ^ person. im -19- (16) (16) 200405913 For the air permeability (air permeability) of air-permeable materials, according to the Gurley method of JI s L 1 〇96, it is 100 seconds / 1 0 0 cc or less, preferably 10 seconds /; [〇〇cc or less. If the air permeability is more than 100 seconds / 100 c c, the moisture permeability will be reduced, so there may be problems in the moisture absorption performance as a dehumidifier. For breathable materials, non-woven fabrics can be exemplified, and a spunbond fabric method, a spun lace method, a card method, a hot emboss card method, and the like can be used. Any manufacturing method. Among them, the spunbond fabric method is preferable in terms of strength, price, and the like. The weight per unit area is from 10 to 100 g / m2 in terms of strength and price, and preferably from 15 to 70 g / m2. Furthermore, the layer structure in the case of non-woven fabric may include a single layer and multiple layers. When considering the suitability for thermal lamination, a multilayer non-woven fabric with a high melting point resin non-woven layer / low melting point resin non-woven layer is more suitable. In addition, as for the non-woven material, well-known resins such as polyolefins such as pp (polypropylene) and PE (polyethylene), polyamides such as NY (nylon), and esters such as PET (polyester) can be used at will. Of it. In the case of the above-mentioned multi-layer nonwoven fabric, as a combination of the melting point difference of the presentation layer, PET nonwoven fabric / PE nonwoven fabric can be exemplified. Examples of the core material include non-woven fabrics using fibers such as polyethylene terephthalate, polybutylene terephthalate, and the like, which are covered with a polyolefin resin. As the material of the air-permeable material, a woven fiber fabric is exemplified. Filler-20- (17) 200405913 Non-woven fabric refers to those who use a polyolefin film to cut into small cracks to form a flat yarn (flat yarn). The material is laminated in the direction and is made of non-woven material by hot-melt gluing or hot-melt bonding. The weight per unit area of the panel fiber nonwoven fabric is from 10 to 100 g / m2, preferably from 12 to 40 g / m2 in terms of strength and price.

In addition, for the stretched film to be used, when considering the suitability of thermal lamination, a multilayer type of a low melting point resin layer / high melting point resin layer / low melting point resin layer is preferably used. As the material capable of thermal lamination with the microporous film layer, a low density polyethylene / high density polyethylene / low density polyethylene is preferred. [Paper layer] The paper used for the paper layer of the present invention is not particularly limited, and it is a paper or a plurality of types of fibers such as pulp, lime tree, yellow scent, natural cellulose, regenerated cellulose, fluorescein, and acetate fiber. Western paper and Japanese paper obtained by mixing papers. The type of paper can be appropriately selected in consideration of the type of packaged material, powderiness, air permeability, shape and size of the remaining margin of the package. The unit weight of paper is usually 10 to 100 g / m2, preferably 12 to 70 g / m2. The unit area is heavy, and the type, powderiness, and air permeability of the package can also be considered. The shape and size of the remaining side of the package are appropriately selected. -21-(18) (18) 200405913 [Lamination processing] The packaging lamination material of the present invention is attached to a microporous film layer or a paper layer, and a polyethylene resin spunbond fabric is non-woven or The heat-resistant air-permeable heat-resistant fiber material layer with a heat resistance of 150 or more is preferably a heat-bonded lamination layer that is subjected to a hot emboss roll method. These layers can be laminated in advance. This pre-lamination can be carried out by a hot flat roll method, preferably by a hot embossing roll method. Among them, when a spunbond nonwoven fabric having a melting point of 150 to 300 ° C is used as a heat-resistant fiber material layer, a polyethylene resin spunbond nonwoven fabric and polypropylene, polyamide, poly Ester and other spunbond fabrics and nonwoven fabrics can be laminated on-line in the manufacture of spunbond fabrics and nonwoven fabrics. They can also be laminated together with subsequent microporous film layers or paper layers. The significance of providing this breathable heat-resistant fiber material layer is that when the microporous film layer or paper layer and the polyethylene-based spunbond fabric nonwoven are laminated by the thermal knurling roller method, the temperature for thermal bonding ( Roller temperature) The temperature of one roller is set without being affected by the melting point of the polyethylene resin spunbond nonwoven fabric. Therefore, the range of conditions for thermal bonding is widened, and as a result, lamination is significantly improved. In addition, when heat-sealing the package body, the heat-resistant fiber material layer does not melt and maintains strength, and as a result, the edges of the heat-sealed portion can be prevented from being broken. Thereby, excellent sealing performance can be exhibited. The melting point of the thermoplastic resin constituting each of the non-woven fabrics or films used in the present invention can be used as the standard J S K 7 1 2 1 D S C (-22-
