従来より、書籍、用紙結束、検札などの軽量品又は貴重品を包装するには、合成樹脂バンド、ビニール包装、ストレッチ包装が主に使用されてきたが、軽量物の包装については、省資源・省エネルギーの観点から、紙製の帯封バンドが市場で使用されつつある。
紙幣結束用帯封紙においても、自動結束機により熱接着できるように、紙やそれに合成樹脂をラミネートした支持体に溶剤型、ホットメルト型又はエマルション型の接着剤から形成された接着剤層を有するものが提供されている。
Conventionally, synthetic resin bands, vinyl packaging, and stretch packaging have been mainly used to wrap lightweight items such as books, paper bundles, and check tags, or valuable items. From the viewpoint of energy saving, paper bandages are being used in the market.
Even in the case of banknote binding paper, it has an adhesive layer formed from a solvent-type, hot-melt type, or emulsion-type adhesive on a paper or a support laminated with a synthetic resin so that it can be thermally bonded by an automatic binding machine. Things are offered.
近年の環境保護・省資源・省エネルギー意識の高まりやコスト削減の観点などから、再生紙化を考慮した紙製帯封紙が多く採用されている。特に接着剤層についてもヒートシール性を維持しながら古紙回収後に紙幣と共にリサイクル可能な接着剤も使用されるようになった（例えば、特許文献１、特許文献２、特許文献３参照）。
しかしながら、これらのリサイクル可能な接着剤は、その離解性能を意識するあまり、湿熱条件化での耐ブロッキング性能に劣っていたり、結束機での搬送性が悪い等の問題点を有していた。

Further, in the banding paper having the above water disintegrating property, the present invention is such that a wax is mixed with the water disintegrating emulsion type adhesive, and the content of the wax is 100 parts by mass of the resin component of the water disintegrating emulsion type adhesive. On the other hand, a band seal paper having a water disintegrating property of 1.0 to 8.0 parts by mass is provided.
Further, according to the present invention, in the banding paper having water disintegrating property, the sealing strength when the water sealing material having water disintegrating property is heated and sealed at 200 ° C. and 2 kgf / cm 2 for 1 second is 1.5 N / A band-wrapping paper having a water disintegrating property of 15 mm or more is provided.
本発明の水離解性を有する帯封紙は、ヒートシール強度が高く、耐ブロッキング性に優れ、帯封機での搬送性に優れ、かつ、古紙リサイクルを可能な水離解性にも優れている。 The banding paper having water disintegrating property of the present invention has high heat seal strength, excellent blocking resistance, excellent transportability in a banding machine, and excellent water disintegrating property capable of recycling used paper.
本発明において、紙基材は、パルプ繊維、合成繊維又は化学繊維からなる紙のテープである。パルプ繊維としては、木材パルプやマニラ麻などのパルプ繊維からなるものが好ましく、木材パルプの具体例としては、針葉樹パルプ、広葉樹パルプ又はこれらの混合物などが挙げられる。また、これらのパルプを漂白精製処理した晒パルプ、漂白精製処理を行わない未晒パルプ、その中間の半晒パルプなども使用できる。これらの中で、特に、針葉樹晒クラフトパルプ（ＮＢＫＰ）、広葉樹晒クラフトパルプ（ＬＢＫＰ）及びこれらの混合物を含むものが好ましい。また、古紙再生パルプも使用できる。パルプ繊維は、１種単独で用いてもよいし、２種以上を組み合わせてもよい。さらに、必要に応じて、パルプ繊維には、合成繊維及び化学繊維から選ばれる少なくとも１種の繊維を混合してもよい。合成繊維の具体例としては、アクリル繊維、ポリエステル繊維、ビニロン繊維などが挙げられる。化学繊維の具体例としては、レーヨン繊維、アセテート繊維などが挙げられる。 In the present invention, the paper substrate is a paper tape made of pulp fiber, synthetic fiber or chemical fiber. The pulp fibers are preferably made of pulp fibers such as wood pulp and manila hemp, and specific examples of wood pulp include softwood pulp, hardwood pulp or a mixture thereof. Further, bleached pulp obtained by bleaching and purifying these pulps, unbleached pulp not subjected to bleaching and refining, and intermediate half-bleached pulp can be used. Of these, those containing softwood bleached kraft pulp (NBKP), hardwood bleached kraft pulp (LBKP) and mixtures thereof are particularly preferred. Also, recycled paper pulp can be used. A pulp fiber may be used individually by 1 type and may combine 2 or more types. Furthermore, you may mix at least 1 sort (s) of fiber chosen from a synthetic fiber and a chemical fiber with a pulp fiber as needed. Specific examples of the synthetic fiber include acrylic fiber, polyester fiber, and vinylon fiber. Specific examples of the chemical fiber include rayon fiber and acetate fiber.
また、紙には、填料を含有させることができる。填料としては、タルク、炭酸カルシウム、クレー、カオリナイト、酸化チタン、酸化亜鉛、硫酸バリウムなどが挙げられる。填料は、１種単独で用いてもよいし、２種以上を組み合わせて用いてもよい。
紙基材の厚みは、帯封紙として使用できる厚みであれば特に制限ないが、通常坪量で４０〜３００ｇ／ｍ２が好ましい。
Further, the paper can contain a filler. Examples of the filler include talc, calcium carbonate, clay, kaolinite, titanium oxide, zinc oxide, and barium sulfate. A filler may be used individually by 1 type and may be used in combination of 2 or more type.
The thickness of the paper substrate is not particularly limited as long as it can be used as a banding paper, but is usually preferably 40 to 300 g / m 2 in basis weight.
本発明において使用する水離解性エマルション型接着剤は、ガラス転移温度０〜３０℃の熱可塑性ビニル樹脂を主成分とする。ガラス転移温度が０℃未満である場合は、夏場における高温条件下での長期保管時にブロッキングのトラブルが発生しやすくなため好ましくない。一方、ガラス転移温度が３０℃を超える場合は、帯封紙の接着に必要な熱量の増加や摩擦係数（静摩擦、動摩擦）が低下することによる帯封紙の搬送不良を発生させるため好ましくない。 The water disintegrating emulsion type adhesive used in the present invention is mainly composed of a thermoplastic vinyl resin having a glass transition temperature of 0 to 30 ° C. A glass transition temperature of less than 0 ° C. is not preferable because blocking troubles are likely to occur during long-term storage under high temperature conditions in summer. On the other hand, when the glass transition temperature exceeds 30 ° C., it is not preferable because an increase in the amount of heat necessary for bonding the bandage paper and a poor conveyance of the bandage paper due to a decrease in the friction coefficient (static friction, dynamic friction) occur.

The transition temperature may be adjusted to 0 to 30 ° C, preferably 5 to 25 ° C, particularly preferably 10 to 22 ° C.
また、水離解性エマルション型接着剤には、ワックスを混合してもよい。ワックスを添加することにより、ブロッキングの一層の抑制に効果的である。ワックスは接着剤成分に適度な滑り性を付与することができ、接着剤の樹脂成分のガラス転移温度が低くても効果的にブロッキングを抑制することが可能となる。

水離解性エマルション型接着剤には、ブロッキングを抑制する目的で、必要に応じて、炭酸カルシウム、酸化チタン、タルク、カオリン、酸化亜鉛、水酸化アルミニウム、炭酸マグネシウムなどの無機系充填剤の１種以上を適宜配合することができる。この無機系充填剤は、摩擦性やヒートシール性を低下させる恐れがあるため、含有量は樹脂成分およびワックスの合計量１００質量部に対して、１０質量部以下が好ましく、０．１〜８質量部が特に好ましい。
The content of the wax is preferably 1 to 8 parts by mass and particularly preferably 2 to 6 parts by mass with respect to 100 parts by mass of the resin component of the water disintegrating emulsion type adhesive. If the amount of the wax is too small, the anti-blocking property particularly under high temperature and high humidity is lowered. If the amount of the wax is too large, the friction coefficient is lowered, the water disintegration property is lowered, and the heat seal strength may be lowered.
The density | concentration of the wax in a wax emulsion should just be 30-70 mass% normally, and 40-60 mass% is preferable.
For water disintegrating emulsion type adhesives, one kind of inorganic fillers such as calcium carbonate, titanium oxide, talc, kaolin, zinc oxide, aluminum hydroxide, magnesium carbonate is used for the purpose of suppressing blocking. The above can be blended as appropriate. Since this inorganic filler may reduce friction and heat sealability, the content is preferably 10 parts by mass or less with respect to 100 parts by mass of the total amount of the resin component and the wax, and 0.1 to 8 Part by mass is particularly preferred.
また、水離解性エマルション型接着剤には、必要に応じて、本発明の性能に悪影響を与えない範囲で、可塑剤、分散剤、消泡剤などの助剤の１種以上を含有させてもよい。
本発明においては、紙基材の少なくとも片面に、水離解性エマルション型接着剤を塗布してヒートシール性を有する接着剤層を形成する。
この接着剤層のポリアセタール板に対する静摩擦係数は、０．２５以上であり、より好ましくは０．２８以上である。静摩擦係数が０．２５未満であると、結束機で使用する際に摩擦力不足に伴う搬送不良を発生させる。
静摩擦係数の上限値は、特に限定されないが、０．７以下が好ましく、０．６以下がより好ましく、０．５以下が特に好ましい。
In addition, the water disintegrating emulsion type adhesive may contain one or more auxiliary agents such as a plasticizer, a dispersant, and an antifoaming agent as long as they do not adversely affect the performance of the present invention. Also good.
In the present invention, a water disintegrating emulsion-type adhesive is applied to at least one surface of a paper substrate to form an adhesive layer having heat sealability.
The static friction coefficient of the adhesive layer with respect to the polyacetal plate is 0.25 or more, more preferably 0.28 or more. When the static friction coefficient is less than 0.25, a conveyance failure due to insufficient frictional force occurs when used in a binding machine.
The upper limit of the static friction coefficient is not particularly limited, but is preferably 0.7 or less, more preferably 0.6 or less, and particularly preferably 0.5 or less.
水離解性を有する帯封紙を２００℃、２ｋｇｆ／ｃｍ２で１秒間加熱しヒートシールを行った際のシール強度は、１．５Ｎ／１５ｍｍ以上であることが好ましい。１．５Ｎ／１５ｍｍ未満であると、結束後にヒートシールを行った部分が自然に剥れたり、落下などにより強い衝撃が加わった際に剥れを生じさせたり、搬送時に剥れが生じたりする恐れがある。
接着剤の塗工量は、５〜２５ｇ／ｍ２であることが好ましく、１０〜２０ｇ／ｍ２であることが特に好ましい。接着剤の塗工量が５ｇ／ｍ２未満であると、目的とするヒートシール強度が得られ難くなり、２５ｇ／ｍ２を超えると、乾燥能力への負荷、及び各種原価が高くなる。
It is preferable that the sealing strength when the band seal paper having water disintegrating property is heated and sealed at 200 ° C. and 2 kgf / cm 2 for 1 second is 1.5 N / 15 mm or more. If it is less than 1.5 N / 15 mm, the part that has been heat-sealed after bundling will be peeled off naturally, or may be peeled off when a strong impact is applied due to dropping or peeling off during transportation. There is a fear.
The coating amount of the adhesive is preferably 5 to 25 g / m 2, and particularly preferably 10 to 20 g / m 2. When the coating amount of the adhesive is less than 5 g / m 2 , it becomes difficult to obtain the target heat seal strength, and when it exceeds 25 g / m 2 , the load on the drying capacity and various costs increase.
水離解性エマルション型接着剤の塗工方法としては、例えば、バーコーター、エアナイフコーター、カーテンコーターなど一般に公知の方法が挙げられる。
本発明においては、上記接着剤層が設けられている紙基材の面とは反対の面に、防滑性、カール防止性などを付与するために、防滑剤、防滑剤を含有するポリビニルアルコール、デンプンなどを塗工してもよい。
Examples of the coating method of the water disintegrating emulsion type adhesive include generally known methods such as a bar coater, an air knife coater, and a curtain coater.
