Abstract
Description
本発明は、例えばパウチ等の袋体（収容部）として使用される包装材料に関する。 The present invention relates to a packaging material used as a bag body (accommodation portion) of, for example, a pouch.
アルミニウム箔を含む包装材料で作製されたパウチは、例えば飲食品、医薬品、化粧品等の各種製品の容器として汎用されている。パウチは、ペットボトル、缶等と比較して、例えば１）持ち運びが容易である、２）老人及び子供でも握りやすい、３）半固体又はゲル状物であっても握力で容易に押し出せる、４）廃棄しやすい等の理由からその需要は高まりつつある。 Pouches made of packaging materials containing aluminum foil are widely used as containers for various products such as foods and drinks, pharmaceuticals, and cosmetics. Compared to PET bottles, cans, etc., pouches are, for example, 1) easy to carry, 2) easy to grip even for elderly people and children, and 3) easy to push out even semi-solid or gel-like substances with grip strength. 4) The demand is increasing because it is easy to dispose of.
ところで、最近では、生体内における抗酸化作用を期待して、水素を含んだ飲料（以下、「水素水」という。）が開発され、商品化されている。こうした飲料も、例えばスパウト付きのパウチに封入して出荷され、消費者向けに販売されている。 By the way, recently, a beverage containing hydrogen (hereinafter referred to as "hydrogen water") has been developed and commercialized in anticipation of an antioxidant effect in a living body. These beverages are also shipped, for example, in a pouch with a spout and sold to consumers.
このようなパウチを構成するための包装材料としては、例えば内容物と接触する側（すなわち内面側）から、外気と触れる側（すなわち外面側）に向かって、低密度ポリエチレン（ＬＤＰＥ）／ポリブチレンテレフタレート（ＰＢＴ）／アルミニウム箔／ポリエチレンテレフタレート（ＰＥＴ）の順に積層された包装材料が用いられている（例えば特許文献１）。 As a packaging material for forming such a pouch, for example, low density polyethylene (LDPE) / polybutylene from the side in contact with the contents (that is, the inner surface side) toward the side in contact with the outside air (that is, the outer surface side). A packaging material in which terephthalate (PBT) / aluminum foil / polyethylene terephthalate (PET) is laminated in this order is used (for example, Patent Document 1).
また、水素水を充填するためのパウチ容器を構成する外装シートとして、ポリエチレン／アルミニウム箔／ＰＥＴの積層体を使用する包装材料も知られている（特許文献２）。 Further, a packaging material using a laminate of polyethylene / aluminum foil / PET as an exterior sheet constituting a pouch container for filling hydrogen water is also known (Patent Document 2).
上記のような水素水を収容するパウチに代表されるように、その包装材料として、特にガス透過性が低く、充填されたガスを漏れにくくするためのバリア層としてアルミ二ウム箔が必須とされている。そして、このようなパウチには、取扱い性（柔軟性）、経済性、軽量化等の観点より極めて薄いアルミニウム箔が使用されている。 As typified by the pouch that stores hydrogen water as described above, aluminum foil is indispensable as a packaging material for the packaging material, especially as a barrier layer that has low gas permeability and makes it difficult for the filled gas to leak. ing. For such a pouch, an extremely thin aluminum foil is used from the viewpoints of handleability (flexibility), economy, weight reduction, and the like.
しかしながら、このような薄いアルミニウム箔は、少なからず微細なピンホール（貫通孔）が存在している。一般的な飲料には、このようなピンホールが存在してもそれほど問題は生じないが、水素水等のように極めて微細なガス成分を液中に溶解させるような場合には、溶存水素（水素分子）がピンホールを通り抜けることができる結果、水素濃度の大幅な低下をもたらし、商品価値を下げてしまうという問題がある。 However, such a thin aluminum foil has not a few fine pinholes (through holes). The presence of such pinholes does not cause much problem in general beverages, but when extremely fine gas components such as hydrogen water are dissolved in the liquid, dissolved hydrogen (dissolved hydrogen) As a result of the hydrogen molecule) being able to pass through the pinhole, there is a problem that the hydrogen concentration is significantly reduced and the commercial value is lowered.
しかも、アルミニウム箔を含む包装材料を用いてパウチを製作する場合、一般的には飲み口となるスパウトをパウチとの一体的な成形により設けられるが、その場合にスパウト周辺部の極めて小さな隙間から溶存水素が漏れる場合もある。 Moreover, when a pouch is manufactured using a packaging material containing aluminum foil, a spout that serves as a spout is generally provided by integral molding with the pouch, but in that case, from an extremely small gap around the spout. Dissolved hydrogen may leak.
一方、ピンホールが一切ない部分だけを用いるべく、アルミニウム箔のピンホールの有無を事前に検査し、ピンホールのない部分だけを切り出して利用する方法も考えられるが、その検査に時間・費用がかかるうえ、アルミニウム箔の歩留まりが大幅に低下するため、大量生産することができなくなる。また、前記のスパウト周辺からの漏れのないパウチを提供するために事前検査をする場合も同様の問題が起こる。 On the other hand, in order to use only the part without pinholes, it is conceivable to inspect the presence or absence of pinholes in the aluminum foil in advance and cut out only the part without pinholes, but the inspection takes time and cost. In addition, the yield of the aluminum foil is significantly reduced, which makes mass production impossible. Further, the same problem occurs when the pre-inspection is performed in order to provide the pouch without leakage from the spout area.
従って、本発明の主な目的は、比較的構成しやすい層構造を有しつつ、水素ガス等の透過を効果的に抑制できる包装材料を提供することにある。また、本発明は、水素水等の収容に適した容器を提供することも目的とする。 Therefore, a main object of the present invention is to provide a packaging material that can effectively suppress the permeation of hydrogen gas or the like while having a layer structure that is relatively easy to construct. Another object of the present invention is to provide a container suitable for storing hydrogen water or the like.
本発明者は、従来技術の問題点に鑑みて鋭意研究を重ねた結果、特定の積層構造を採用することにより上記目的を達成できることを見出し、本発明を完成するに至った。 As a result of intensive studies in view of the problems of the prior art, the present inventor has found that the above object can be achieved by adopting a specific laminated structure, and has completed the present invention.

本発明の包装材料では、これらの層以外の層も必要に応じて設けられていても良い。例えば、接着剤層、印刷層、オーバーコート層等が挙げられる。従って、各層間には、必要に応じて接着剤層（図示せず）が形成されていても良い。特に、第１アルミニウム箔１２と、第２アルミニウム箔１３との間に接着剤層が介在していることが好ましい。 In the packaging material of the present invention, layers other than these layers may be provided as needed. For example, an adhesive layer, a printing layer, an overcoat layer and the like can be mentioned. Therefore, an adhesive layer (not shown) may be formed between the layers, if necessary. In particular, it is preferable that an adhesive layer is interposed between the first aluminum foil 12 and the second aluminum foil 13.
この包装材料を用いて容器（収容部）を構成する場合は、例えば第１ポリエステル系樹脂層１１が内面として露出するように容器（例えば袋体）を作製すれば良い。例えば、袋体を作製する場合は、内容物の種類等に応じて例えばガゼット袋、スタンディング袋、三方袋等の各種のタイプの袋体を適宜選択することができる。 When a container (accommodation portion) is constructed using this packaging material, for example, the container (for example, a bag body) may be prepared so that the first polyester resin layer 11 is exposed as an inner surface. For example, when producing a bag, various types of bags such as a gusset bag, a standing bag, and a three-sided bag can be appropriately selected according to the type of contents and the like.
また、本発明の包装材料を用いて容器を製造する場合、特に第１樹脂層１１がヒートシール性を有する場合はそれを利用することによって容器を構成することができる。また、別途に接着剤（ヒートシール剤等）を用いることによって容器を構成することもできる。接着剤としては、公知又は市販のものを使用することができる。以下においては、本発明の包装材料を構成し得る各層について説明する。 Further, when a container is manufactured using the packaging material of the present invention, particularly when the first resin layer 11 has a heat-sealing property, the container can be constructed by using the first resin layer 11. Further, the container can be configured by separately using an adhesive (heat sealant or the like). As the adhesive, a known or commercially available adhesive can be used. In the following, each layer that can constitute the packaging material of the present invention will be described.
（１）第１樹脂層
第１樹脂層を構成する樹脂としては、例えばフィルム、塗料等の形態で使用されているものであれば限定されない。例えば、ポリオレフィン（ポリエチレン、ポリプロピレン等）、ポリエステル（ポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリエチレンナフタレート等）等のほか、ポリスチレン、ポリカーボネート、ポリアクリロニトリル、ポリイミド、ポリアミド、ポリビニルアルコール、塩化ビニル、ポリ塩化ビニリデン、メタクリル樹脂、エチレン−酢酸ビニル共重合体、エチレン−ビニルアルコール共重合体等の少なくとも１種を好適に用いることができる。
(1) First Resin Layer The resin constituting the first resin layer is not limited as long as it is used in the form of, for example, a film or a paint. For example, in addition to polyolefins (polyethylene, polypropylene, etc.), polyesters (polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, etc.), polystyrene, polycarbonate, polyacrylonitrile, polyimide, polyamide, polyvinyl alcohol, vinyl chloride, polyvinylidene chloride, methacryl. At least one of a resin, an ethylene-vinyl acetate copolymer, an ethylene-vinyl alcohol copolymer and the like can be preferably used.
第１樹脂層は、単層又は複層から構成されている。複層から構成される場合は、２層又は３層以上が積層された構造を採用できる。複層の場合も、各層は、上記で例示した樹脂で構成されていることが好ましい。複層とする場合は、例えばａ）各層を構成し得るフィルムを予め成形した後、これらを積層することにより複層を得る方法、ｂ）樹脂成分を含む塗料から得られる塗膜を積層することにより複層を得る方法、ｃ）前記フィルム及び塗膜とを組み合わせることによって複層を得る方法等のいずれも採用することができる。 The first resin layer is composed of a single layer or a plurality of layers. When composed of a plurality of layers, a structure in which two layers or three or more layers are laminated can be adopted. Even in the case of a plurality of layers, it is preferable that each layer is composed of the resin exemplified above. In the case of forming multiple layers, for example, a) a method of obtaining multiple layers by pre-molding a film capable of forming each layer and then laminating them, and b) laminating a coating film obtained from a coating film containing a resin component. A method of obtaining a plurality of layers by means of a method, c) a method of obtaining a plurality of layers by combining the film and the coating film, and the like can be adopted.
第１樹脂層の厚み（複層の場合は合計厚み）は限定的ではないが、通常は９〜２５μｍの範囲内で適宜設定することが好ましい。この範囲内に設定することによって、例えば本発明の包装材料をスパウト付きパウチの袋体の材料として用いる場合等において、突き刺し強度に強く、かつ、スパウトの成形又は取り付けも容易になる。 The thickness of the first resin layer (total thickness in the case of a plurality of layers) is not limited, but is usually preferably set appropriately within the range of 9 to 25 μm. By setting within this range, for example, when the packaging material of the present invention is used as a material for a bag of a pouch with a spout, the piercing strength is strong and the spout can be easily molded or attached.
第１樹脂層では、少なくとも被包装物と接触する層（内壁層）に各種の添加剤が含まれていても良い。例えば、水素発生物質、防腐剤、抗菌剤、酸化防止剤、着色剤等が挙げられる。例えば、被包装物が飲用水素水である場合は、少なくとも内壁層に水素発生物質が含まれていることが好ましい。水素発生物質を内壁層中に添加することにより、当該物質が水と反応することにより発生する水素ガスによって、被包装物（内容物）である飲用水素水の水素濃度の低下を効果的に抑制することができる。 In the first resin layer, at least the layer (inner wall layer) in contact with the object to be packaged may contain various additives. For example, hydrogen generating substances, preservatives, antibacterial agents, antioxidants, colorants and the like can be mentioned. For example, when the packaged object is drinking water, it is preferable that at least the inner wall layer contains a hydrogen generating substance. By adding a hydrogen generating substance to the inner wall layer, the hydrogen gas generated by the reaction of the substance with water effectively reduces the hydrogen concentration of drinking hydrogen water, which is the packaged substance (contents). It can be suppressed.
水素発生物質としては、水と反応することにより水素ガスを発生するものであれば限定されないが、本発明では高反応性という見地よりアルミニウム粉末及びマグネシウム粉末の少なくとも１種を好適に用いることができる。これらの粉末の平均粒径は、通常は１〜３０μｍ程度とすることが好ましい。このような粉末自体は公知又は市販のものを使用することができる。水素発生物質の含有量は、所望の水素補給量等に応じて適宜調節できるが、通常は内壁層中に１〜２０質量％含有させることにより水素を十分に供給することができる。 The hydrogen generating substance is not limited as long as it generates hydrogen gas by reacting with water, but in the present invention, at least one of aluminum powder and magnesium powder can be preferably used from the viewpoint of high reactivity. .. The average particle size of these powders is usually preferably about 1 to 30 μm. As such a powder itself, a known or commercially available powder can be used. The content of the hydrogen generating substance can be appropriately adjusted according to the desired amount of hydrogen replenishment and the like, but usually, hydrogen can be sufficiently supplied by containing 1 to 20% by mass in the inner wall layer.
また、内壁層中に水素発生物質が含まれている場合は、内壁層としてポリエチレン、特に低密度ポリエチレン（ＬＤＰＥ）を用いることが好ましい。ＬＰＤＥを用いることによって、被包装物（内容物）である飲用水素水と水素発生物質が接触・反応しやすくなる結果、より効果的に水素ガスを発生させることができ、その水素ガスが飲用水素水に溶解することによって水素濃度の低下を効果的に抑制ないしは防止することが可能となる。 When a hydrogen generating substance is contained in the inner wall layer, it is preferable to use polyethylene, particularly low density polyethylene (LDPE), as the inner wall layer. By using LPDE, it becomes easier for the drinking hydrogen water, which is the packaged object (contents), to come into contact with and react with the hydrogen generating substance, and as a result, hydrogen gas can be generated more effectively, and the hydrogen gas can be drunk. By dissolving in hydrogen water, it becomes possible to effectively suppress or prevent a decrease in hydrogen concentration.
内壁層に水素発生物質を含有させる方法は限定的でなく、例えば樹脂成分及び粉末状水素発生物質を含む混合物をフィルム状に成形する工程を含む方法を採用することができる。このようにして得られた水素発生物質含有フィルムを他の層と積層することによって本発明の包装材料を構成することができる。 The method of incorporating the hydrogen generating substance in the inner wall layer is not limited, and for example, a method including a step of forming a mixture containing a resin component and a powdered hydrogen generating substance into a film can be adopted. The packaging material of the present invention can be constructed by laminating the hydrogen generating substance-containing film thus obtained with another layer.
（２）第１アルミニウム箔
第１アルミニウム箔は、１枚の厚さが５〜５０μｍである。アルミニウム箔の厚さが５μｍ未満であると内容物（例えば飲用水素水に含まれる水素）の漏れが増大してしまう。５０μｍを超える場合は、例えば本発明の包装材料からなる袋体にスパウトを形成した場合に第１樹脂層が破れたり、亀裂が入るおそれがある。
(2) First Aluminum Foil The thickness of one first aluminum foil is 5 to 50 μm. If the thickness of the aluminum foil is less than 5 μm, leakage of the contents (for example, hydrogen contained in drinking hydrogen water) will increase. If it exceeds 50 μm, for example, when a spout is formed on a bag made of the packaging material of the present invention, the first resin layer may be torn or cracked.
第１アルミニウム箔の組成は、特に限定されないが、例えばＡｌ−Ｍｎ系の「１Ｎ３０」、「３００４」のほか、高加工性、高バリア性を有するＡｌ−Ｆｅ系の「８０２１」、「８０７９」等を好適に用いることができる。 The composition of the first aluminum foil is not particularly limited, but for example, in addition to the Al-Mn-based "1N30" and "3004", the Al-Fe-based "8021" and "8079" having high workability and high barrier properties. Etc. can be preferably used.
また、第１アルミニウム箔は、軟質に調質されている箔（軟質箔）であることが好ましい。アルミニウム箔が硬質箔であると、軟質箔を用いた場合に比べてスパウト成形時等にアルミニウム箔が割れやすくなるおそれがある。 Further, the first aluminum foil is preferably a foil (soft foil) that has been tempered to be soft. If the aluminum foil is a hard foil, the aluminum foil may be more easily cracked during spout molding or the like as compared with the case where a soft foil is used.
第１アルミニウム箔の耐力は特に制限されないが、通常は５〜５０Ｎ／ｍｍ２程度の範囲内で適宜設定することができる。特に、後記の第２アルミニウム箔と同じアルミニウム箔も好適に使用することができる。 The proof stress of the first aluminum foil is not particularly limited, but usually it can be appropriately set within the range of about 5 to 50 N / mm 2 . In particular, the same aluminum foil as the second aluminum foil described later can also be preferably used.
第１アルミニウム箔は、これらの物性を備えていれば、公知又は市販のアルミニウム箔も使用することもできる。 As the first aluminum foil, known or commercially available aluminum foil can also be used as long as it has these physical characteristics.
（３）第２アルミニウム箔
第２アルミニウム箔は、１枚の厚さが５〜５０μｍである。アルミニウム箔の厚さが５μｍ未満であると内容物（例えば水素水に含まれる水素）の漏れが増大してしまう。５０μｍを超える場合は、例えば本発明の包装材料からなる袋体にスパウトを取り付けた場合に第１樹脂層が破れたり、亀裂が入るおそれがある。
(3) Second Aluminum Foil The thickness of one second aluminum foil is 5 to 50 μm. If the thickness of the aluminum foil is less than 5 μm, leakage of the contents (for example, hydrogen contained in hydrogen water) will increase. If it exceeds 50 μm, for example, when the spout is attached to the bag body made of the packaging material of the present invention, the first resin layer may be torn or cracked.
第２アルミニウム箔の組成は特に限定されないが、Ａｌ−Ｍｎ系の「１Ｎ３０」、「３００４」のほか、高加工性、高バリア性を有するＡｌ−Ｆｅ系の「８０２１」、「８０７９」等を好適に用いることができる。 The composition of the second aluminum foil is not particularly limited, but in addition to the Al-Mn-based "1N30" and "3004", the Al-Fe-based "8021" and "8079" having high workability and high barrier properties are used. It can be preferably used.
また、第２アルミニウム箔は、軟質に調質されている箔（軟質箔）であることが好ましい。アルミニウム箔が硬質箔であると、軟質箔を用いた場合に比べてスパウト成形時等にアルミニウム箔が割れやすくなるおそれがある。 Further, the second aluminum foil is preferably a foil (soft foil) that has been tempered to be soft. If the aluminum foil is a hard foil, the aluminum foil may be more easily cracked during spout molding or the like as compared with the case where a soft foil is used.
第２アルミニウム箔の耐力は、５〜５０Ｎ／ｍｍ２程度、好ましくは５〜４０Ｎ／ｍｍ２の範囲内とする。これによって、例えばスパウト成型一体加工の際にもアルミニウム箔がスパウト形状に追従させることができる結果、被包装物（特に水素水に含まれる水素）の漏れを効果的に抑制ないしは防止することができる。 The proof stress of the second aluminum foil is about 5 to 50 N / mm 2 , preferably within the range of 5 to 40 N / mm 2 . As a result, for example, the aluminum foil can follow the spout shape even during the spout molding integral processing, and as a result, the leakage of the packaged object (particularly hydrogen contained in hydrogen water) can be effectively suppressed or prevented. ..
第２アルミニウム箔は、これらの物性を備えていれば、公知又は市販のアルミニウム箔も使用することもできる。 As the second aluminum foil, known or commercially available aluminum foil can also be used as long as it has these physical characteristics.
第２アルミニウム箔と第１アルミニウム箔とを重ねて貼り合わせる。この際に、お互いの貼り合わせる面は、一方がケシ面、もう一方がツヤ面であることが好ましい。互いにツヤ面どうし又はケシ面どうしで重ね合わせると、加工適正が悪くなり、歩留まり低下の原因となることがある。 The second aluminum foil and the first aluminum foil are overlapped and bonded together. At this time, it is preferable that one of the surfaces to be bonded to each other is a poppy surface and the other is a glossy surface. If the glossy surfaces or the poppy surfaces are overlapped with each other, the processing suitability deteriorates, which may cause a decrease in yield.
第１アルミニウム箔と第２アルミニウム箔とを重ねる場合は、他の層を介在させることなく積層することもできるが、特に接着剤層を介して積層することが好ましい。これにより、両アルミニウム箔を強固に接合（積層）できるとともに、層間に生じ得る隙間をより確実になくすこともできる。接着剤層に用いる接着剤としては特に限定されず、例えばウレタン系接着剤、ポリエステル系接着剤、ポリエーテル系接着剤等の合成樹脂系接着剤が挙げられる。このうち、ドライラミネート用接着剤等として使用されているものを好適に用いることができる。本発明では、特にウレタン系接着剤を好適に用いることができる。ウレタン系接着剤（特に２液硬化型ウレタン系接着剤）は、ドライラミネーションに適しているうえ、強靭な皮膜層を形成し、優れた耐久性を発揮するという点で他の接着剤よりも有利である。 When the first aluminum foil and the second aluminum foil are laminated, they can be laminated without interposing another layer, but it is particularly preferable to laminate the first aluminum foil and the second aluminum foil via an adhesive layer. As a result, both aluminum foils can be firmly joined (laminated), and gaps that may occur between the layers can be more reliably eliminated. The adhesive used for the adhesive layer is not particularly limited, and examples thereof include synthetic resin adhesives such as urethane adhesives, polyester adhesives, and polyether adhesives. Of these, those used as adhesives for dry laminating and the like can be preferably used. In the present invention, a urethane-based adhesive can be particularly preferably used. Urethane-based adhesives (especially two-component curable urethane-based adhesives) are more suitable for dry lamination, and are more advantageous than other adhesives in that they form a tough film layer and exhibit excellent durability.

The specific shape of the pouch container is not particularly limited when the spout is attached, and it is preferable that the contents cannot be accessed from other than the spout.
本発明の容器に充填できる被包装物（内容物）としては、例えば水、アルコール等の液体のほか、固体、半固体（ゲル状体、高粘性体等）のいずれも適用可能である。また、食品、医薬品、化粧品等の各種の製品にも適用することができる。特に、本発明では、その高い密閉性（バリア性）より水素水（飲用水素水）等にも好適に用いることができる。本発明における水素水は、水素を含有する飲料であれば良く、水単体に限られず、例えば果汁成分、炭酸水、乳成分のほか、甘味料等の食品添加物等が含まれているものも包含される。また、水素水の性状も限定されず、水のような液体のほか、半固体（ゲル状体、高粘性体等）等もすべて包含される。 As the packaged object (contents) that can be filled in the container of the present invention, for example, liquids such as water and alcohol, as well as solids and semi-solids (gels, highly viscous substances, etc.) can be applied. It can also be applied to various products such as foods, pharmaceuticals and cosmetics. In particular, in the present invention, it can be suitably used for hydrogen water (drinking hydrogen water) and the like due to its high airtightness (barrier property).

As a result, the hydrogen concentration was 280 ppb.
以上の結果からも明らかなように、比較例では、いずれも２４時間で３割以上もの水素濃度の大幅な低下が認められた。ちなみに、実際の製品では、製造から出荷及び消費者による消費まで数日〜数ヶ月を要することから、さらに水素濃度に差が生じると考えられる。これに対し、実施例では、いずれも１２００ｐｐｂ以上という比較的高い水素濃度が維持されていることがわかる。 As is clear from the above results, in all the comparative examples, a significant decrease in hydrogen concentration of 30% or more was observed in 24 hours. By the way, in an actual product, it takes several days to several months from manufacturing to shipping and consumption by consumers, so that it is considered that a further difference in hydrogen concentration occurs. On the other hand, in each of the examples, it can be seen that a relatively high hydrogen concentration of 1200 ppb or more is maintained.
