Abstract
Description
本発明は、食品等を包装するシートに塗工するコート剤に関する。 The present invention relates to a coating agent applied to a sheet for packaging food or the like.
従来、食品包装シートは、薄紙、板紙、または不織布等の基材に対して、ラミネート加工や、コート剤を塗工することで、食品から油分等が基材に染み出して基材の強度が低下する問題、および基材を通過した前記油分により手が汚れない問題を解決していた。染み出し成分に対して紙の強度が低下したり手が汚れたりしないような処理が施されて来た。 Conventionally, food packaging sheets are laminated or coated with a coating agent on a substrate such as thin paper, paperboard, or non-woven fabric, so that the oil component oozes out from the food and the strength of the substrate is increased. The problem which falls and the problem which a hand does not get dirty with the said oil component which passed the base material were solved. The exuding component has been subjected to a treatment that does not reduce the strength of the paper or stain the hand.
ここで、前記ラミネート加工を行った基材は、ポリエチレンラミネート紙などが一般的であるが紙リサイクルの観点からはポリエチレンフィルムがリサイクル性を阻害する問題となっていた。リサイクルのためには、ポリエチレンフィルムを取り除く装置を追加する必要があるが、装置の価格が高いため、リサイクル紙の価格も高くなるため市場でのリサイクル紙の利用促進の障害になっていた。そのため、コート剤を使用した食品包装シートの検討がされている。 Here, the laminated base material is generally polyethylene laminated paper or the like, but from the viewpoint of paper recycling, there has been a problem that polyethylene film hinders recyclability. In order to recycle, it is necessary to add a device for removing the polyethylene film. However, since the price of the device is high, the price of the recycled paper is also high, which hinders the promotion of the use of recycled paper in the market. Therefore, food packaging sheets using a coating agent have been studied.
特許文献１では、ポリビニルアルコールから形成した層と、フッ素から形成した層を積層した耐油紙が開示されている。 Patent Document 1 discloses an oil-resistant paper in which a layer formed from polyvinyl alcohol and a layer formed from fluorine are laminated.
特許文献２では、イソシアネート化合物、およびポリビニルアルコールを含むコート財が開示されている。 Patent Document 2 discloses a coated article containing an isocyanate compound and polyvinyl alcohol.
特許文献３では、多孔質無機粒子、アクリルバインダー、パラフィンワックスエマルジョンを含むコート剤が開示されている。 Patent Document 3 discloses a coating agent containing porous inorganic particles, an acrylic binder, and a paraffin wax emulsion.
特許文献４では、コアがメチルメタクリレートと２−エチルヘキシルアクリレートのポリマー、シェルがメチルメタクリレートとメタクリル酸アクリルモノマーのポリマーであるコアシェル型アクリルエマルションを含むコート剤が開示されている。 Patent Document 4 discloses a coating agent containing a core-shell type acrylic emulsion in which the core is a polymer of methyl methacrylate and 2-ethylhexyl acrylate, and the shell is a polymer of methyl methacrylate and acrylic acid acrylic monomer.
しかし、特許文献１の耐油紙は、フッ素の人体への有毒性が指摘されているため積極的な使用は控えたい。 However, since the oil-resistant paper of Patent Document 1 has been pointed out to be toxic to the human body of fluorine, it should not be used actively.
また、食品包装コート紙は、直接食品と接触するため、特許文献２のコート剤は、未反応のイソシアネート化合物が残留すると呼吸器障害、目の炎症、および中枢神経を侵される等の問題がある。
また、特許文献３のコート剤は、多孔質無機粒子を含むため印刷適正が悪く、塗工装置を汚染する問題があった。また前記コート剤を長期保管すると多孔質無機粒子が沈降し、固まることで製造直後に性能が得られない問題があった。
In addition, since the food packaging coated paper is in direct contact with food, the coating agent of Patent Document 2 has problems such as respiratory damage, eye inflammation, and central nervous system attack if unreacted isocyanate compound remains. .
Moreover, since the coating agent of patent document 3 contains porous inorganic particles, there was a problem of poor printing suitability and contamination of the coating apparatus. In addition, when the coating agent is stored for a long period of time, the porous inorganic particles settle and solidify, resulting in a problem that performance cannot be obtained immediately after production.
また、特許文献３のコート剤は、菓子に含まれる植物性油脂に対しては耐油性があったが、肉類等の動物性油脂を含む食品を包装する場合は、耐油性が不足し、包装後の外観不良、手汚れ、基材強度の低下による紙は断等の問題があった Moreover, although the coating agent of patent document 3 was oil-resistant with respect to vegetable oil contained in confectionery, when packaging foods containing animal oil such as meat, the oil resistance is insufficient, and the packaging There was a problem such as paper breakage due to poor appearance afterwards, hand dirt, base material strength decline
本発明は、例えば肉類等の動物性油脂を含む食品を包装する場合に、食品包装後の外観不良、手汚れの発生、基材強度が低下し難く、耐油性が良好な食品包装シートが得られる食品包装シート用コート剤の提供を目的とする。 The present invention provides a food packaging sheet having good oil resistance, for example, when packaging foods containing animal fats such as meat and the like, poor appearance after food packaging, occurrence of hand dirt, substrate strength is difficult to decrease. An object of the present invention is to provide a food packaging sheet coating agent.
本発明は、シェル部が芳香族エチレン性不飽和単量体（ａ−１）と、カルボキシル基含有エチレン性不飽和単量体（ａ−２）とを含むエチレン性不飽和単量体を共重合してなる樹脂（Ａ）、コア部がメチルメタクリレートおよびメチルアクリレートの少なくとも一方と、炭素数２から８のアルキル基含有エチレン性不飽和単量体（ｂ−１）とを含むエチレン性不飽和単量体を共重合してなる樹脂（Ｂ）であるコアシェル型エマルジョンを含む、公正の食品包装シート用コート剤である。 In the present invention, an ethylenically unsaturated monomer having a shell portion containing an aromatic ethylenically unsaturated monomer (a-1) and a carboxyl group-containing ethylenically unsaturated monomer (a-2) is used. Polymerized resin (A), an ethylenically unsaturated core having at least one of methyl methacrylate and methyl acrylate, and an alkyl group-containing ethylenically unsaturated monomer (b-1) having 2 to 8 carbon atoms This is a fair food packaging sheet coating agent comprising a core-shell emulsion that is a resin (B) obtained by copolymerizing monomers.
上記構成の本発明によれば、食品包装シート用コート剤を基材に塗工するとシェル部の樹脂（Ａ）は、基材に染み込むことで親水性のカルボキシル基は、動物性油脂に侵入をし難くし、芳香環は基材強度を強くする。また、コア部の樹脂（Ｂ）は、比較的基材の表面付近に存在する傾向があり、さらに比較的親水性が高いメチルメタクリレートまたはメチルアクリレート、および比較的疎水性が高い炭素数２から８のアルキル基含有エチレン性不飽和単量体（ｂ−１）を使用することで、樹脂（Ｂ）の親水性・疎水性を適切に調整できるため、樹脂（Ａ）と親和性が高く、緻密な樹脂層を形成できるため、動物性油脂の浸透を抑制できる。 According to the present invention having the above structure, when the coating agent for food packaging sheet is applied to the base material, the resin (A) in the shell part soaks into the base material, so that the hydrophilic carboxyl group penetrates into the animal fats and oils. The aromatic ring increases the substrate strength. Further, the resin (B) in the core portion tends to be present in the vicinity of the surface of the base material, methyl methacrylate or methyl acrylate having a relatively high hydrophilicity, and carbon numbers of 2 to 8 having a relatively high hydrophobicity. Since the hydrophilicity / hydrophobicity of the resin (B) can be appropriately adjusted by using the alkyl group-containing ethylenically unsaturated monomer (b-1), the resin (A) has high affinity and is dense. Since a simple resin layer can be formed, the penetration of animal fats and oils can be suppressed.
本発明により、例えば肉類等の動物性油脂を含む食品を包装する場合に、食品包装後の外観不良、手汚れの発生、基材強度が低下し難く、耐油性が良好な食品包装シートが得られる食品包装シート用コート剤を提供できた。 According to the present invention, for example, when packaging foods containing animal fats such as meat, it is possible to obtain a food packaging sheet having good oil resistance, with poor appearance after food packaging, occurrence of hand stains, and low substrate strength. The coating agent for food packaging sheets can be provided.
本発明の食品包装シート用コート剤は、コアシェル型エマルジョンを含む。前記コアシェル型エマルジョンは、シェル部が芳香族エチレン性不飽和単量体（ａ−１）と、カルボキシル基含有エチレン性不飽和単量体（ａ−２）とを含むエチレン性不飽和単量体を共重合してなる樹脂（Ａ）、およびコア部がメチルメタクリレートおよびメチルアクリレートの少なくとも一方と、炭素数２から８のアルキル基含有エチレン性不飽和単量体（ｂ−１）とを含むエチレン性不飽和単量体を共重合してなる樹脂（Ｂ）で構成する。
本発明の食品包装シート用コート剤(以下、コート剤という)は、紙のように表面が多孔質の基材に塗工すると基材に含浸し、耐油性の食品包装コートを得ることが出来る。本発明の食品包装シート用コート剤は、前記コア部と前記シェル部の組合せにより、動物性油脂に対する耐性が向上した。これにより肉類を包装した場合に、動物性油脂の外観不良、手汚れの低減、基材強度が低下し難いという効果が得られた。なお、本発明で基材は、紙、不織布、および織布等の多孔質な表面形状を有するシートである。
The coating agent for food packaging sheets of the present invention contains a core-shell type emulsion. In the core-shell emulsion, an ethylenically unsaturated monomer having a shell portion containing an aromatic ethylenically unsaturated monomer (a-1) and a carboxyl group-containing ethylenically unsaturated monomer (a-2) And ethylene containing at least one of methyl methacrylate and methyl acrylate and an alkyl group-containing ethylenically unsaturated monomer (b-1) having 2 to 8 carbon atoms. The resin (B) is obtained by copolymerizing a polymerizable unsaturated monomer.
The coating agent for food packaging sheet of the present invention (hereinafter referred to as coating agent) can be impregnated into a base material when coated on a porous substrate such as paper to obtain an oil-resistant food packaging coat. . The coating agent for food packaging sheets of the present invention has improved resistance to animal fats and oils due to the combination of the core part and the shell part.

Resin obtained by emulsion polymerization of at least one of methyl methacrylate and methyl acrylate and an ethylenically unsaturated monomer containing an alkyl group-containing ethylenically unsaturated monomer (b-1) having 2 to 8 carbon atoms ( B). The resin (B) copolymerized with such an ethylenically unsaturated monomer uses only an alkyl group-containing ethylenically unsaturated monomer (b-1) having a relatively high hydrophobicity and having 2 to 8 carbon atoms. Then, the hydrophobicity tends to be excessive, and there is a tendency that the oil resistance is lowered and the affinity with the resin (A) is lowered. However, by using at least one of methyl methacrylate and methyl acrylate having relatively high hydrophilicity in combination. Since the balance between hydrophilicity and hydrophobicity can be adjusted appropriately, animal fats can hardly penetrate into the base material. Resin (B) has a good balance between hydrophilicity and hydrophobicity, so it has good affinity with resin (A), and when applied to a substrate, it forms a dense resin layer that makes it difficult for animal fats and oils to penetrate. it can. At the same time, water-soluble components including amino acids that exude from meat can be made difficult to penetrate. Further, the dense resin layer has a good appearance.
