【発明の属する技術分野】
本発明は、耐油性用紙とそれを用いて作製した耐油用カートンに関するものであり、特に揚げ物用の耐油性と耐ムレ性（通気性）を持った用紙およびそれを用いて作製した耐油性テイクアウトカートンに関する。
【０００２】
【従来の技術】
従来、ファーストフード店やコンビニエンスストアなどで販売している揚げたてのコロッケ、フライドチキン等、油分や水分（水蒸気）を放出する食品、特に，加温状態の前記調理済食品を包装する用紙に一般紙を用いると、食品に含まれる油分や水分（水蒸気）が紙の各層を透過して紙の内面から外面に滲み出てしまい、容器が汚れたり、容器に触れた、例えば、手や衣服も汚れてしまうことがある。
【０００３】
このため、▲１▼耐油性、耐水性を有するポリエチレン等のプラスチック樹脂層を用紙の表面に積層する、あるいは用紙の中間層に挟む、▲２▼耐油性、耐水性を有する薬剤を紙の各層に漉き込む、等の処理を施した用紙を用いて調理済食品から発生する油分や水分（水蒸気）の用紙外側への汚染を防いでいた。
【０００４】
ところがこれらの耐油性、耐水性付与策は、▲１▼新たに樹脂層を設けるので、樹脂層がバリア層となって通気性、耐ムレ性が悪くなり、また、油分や水分（水蒸気）の一部は再度揚げ物に移り揚げ物の食感を悪化させたり、用紙のリサイクルも困難でコスト高となる。▲２▼耐水剤、耐油剤の組合せやそれらの機能層の選択方法によっては、押罫部分の耐油性が悪くなり、用紙端面から油分のしみ込みによる油染が発生する等の問題があった。
【０００５】
【発明が解決しようとする課題】
本発明は、油分や水分（水蒸気）の多い揚げたてのコロッケやフライドチキン等の調理済食品を包装する用紙に関する以上のような問題点を除去するためになされたもので、耐油性と耐ムレ性（通気）を持った用紙とそれを用いたテイクアウト用の耐油性カートンを提供することを課題とする。
【０００６】
【課題を解決するための手段】
本発明の請求項１の発明は、波形に成形された中芯原紙の両面にライナーを接着剤を用いて貼合させた両面ダンボールにおいて、坪量が１２５ｇ／ｍ2程度のライナーと坪量が４０ｇ／ｍ2程度の中芯原紙によりＥフルートの両面ダンボールを形成し、両面のうち少なくとも１つの前記ライナーの前記中芯側の片面に溶融押出し加工法によりポリエチレン樹脂膜を形成し、その上にプライマー処理を施すことで耐油層を形成するとともに、前記中芯原紙の片面にアクリル樹脂系耐油剤を塗布することにより第２の耐油層を形成し、前記第２の耐油層の面と前記ライナーの前記耐油層の面を相対向させて前記ライナーと前記中芯原紙を貼合させたことを特徴とする耐油性用紙である。
【０００７】
このように請求項１記載の発明によれば、ライナーと中芯原紙の間に耐油層を介在させて、ライナーと中芯原紙を貼合させているので、内容物からしみ出た油はライナーに吸収され、再び内容物に吸収されることはない。また、ライナーを通過した蒸気は、波形の中芯原紙の間の空間に達して段繰り方向に逃げて行きライナーに湿気がこもらない。従って内容物がべたつかない。
【０００９】
また、耐油層が、ライナーと中芯原紙を貼合させる接着剤に耐油性を有する接着剤を用いた接着層である場合は、内容物からしみ出た油分はライナーに吸収され、再び内容物に吸収されることはない。もしピンホール等で中芯原紙まで油分が染み込んだとしても反対側のライナーと中芯原紙の接着部分でくい止めることができる（二重に防御される）。また、内容物が接触する側のライナーを通過した蒸気は波形の中芯原紙の間の空間に達して、段繰り方向に逃げて行きライナーに湿気がこもらない。従って内容物がべたつかない。
【００１１】
また、耐油層が、アクリル樹脂系耐油剤を塗布することにより形成される耐油層であるので、内容物からしみ出た油分はライナーに吸収され、再び内容物に吸収されることはない。また耐油層により中芯原紙にしみ込むこともない。さらに、内容物が接触する側のライナーを通過した蒸気は波形の中芯原紙の間の空間に達して、段繰り方向に逃げて行きライナーに湿気がこもらない。従って内容物がべたつかない。
【００１６】
また、本発明の請求項２の発明は、上記の耐油性用紙を用いて作製した耐油用カートンである。
【００１７】
【発明の実施の形態】

BACKGROUND OF THE INVENTION
The present invention relates to an oil-resistant paper and an oil-resistant carton produced by using the oil-resistant paper, and in particular, a paper having oil resistance and stuffiness (breathability) for fried food and an oil-resistant take-out produced by using the paper. Regarding the carton.
[0002]
[Prior art]
Conventional paper used to wrap foods that release oil and moisture (water vapor), such as freshly fried croquettes and fried chicken, which have been sold in fast food stores and convenience stores, especially for paper that wraps cooked foods that have been heated. When using, oil or moisture (water vapor) contained in food permeates through each layer of paper and oozes from the inner surface of the paper to the outer surface, and the container becomes dirty or touches the container. May end up.
[0003]
Therefore, (1) a plastic resin layer such as polyethylene having oil resistance and water resistance is laminated on the surface of the paper, or sandwiched between intermediate layers of the paper, and (2) an agent having oil resistance and water resistance is added to each layer of the paper. Using paper that has been treated, for example, oil, moisture (water vapor) generated from cooked foods was prevented from contaminating the outside of the paper.
[0004]
However, these oil resistance and water resistance imparting measures are as follows: (1) Since a new resin layer is provided, the resin layer becomes a barrier layer and the air permeability and stuffiness resistance are deteriorated. Some of them move to deep-fried food again, which worsens the texture of the deep-fried food and makes it difficult to recycle paper, resulting in high costs. (2) Depending on the combination of water- and oil-proofing agents and the method of selecting these functional layers, the oil resistance of the ruled part deteriorates, and there is a problem that oil dyeing occurs due to the penetration of oil from the edge of the paper. .
[0005]
[Problems to be solved by the invention]
The present invention was made to eliminate the above-mentioned problems related to paper for packaging cooked foods such as freshly fried croquettes and fried chicken with a high amount of oil and moisture (water vapor). It is an object of the present invention to provide a sheet having (ventilation) and an oil-resistant carton for take-out using the sheet.
[0006]
[Means for Solving the Problems]
The invention of claim 1 of the present invention is a double-sided cardboard in which liners are bonded to both sides of a core base paper formed into a corrugated shape using an adhesive, and the basis weight is about 125 g / m 2. An E-flute double-sided cardboard is formed with a core base paper of about 40 g / m 2, and a polyethylene resin film is formed on one side of the core side of at least one of the two liners by a melt extrusion process. An oil-resistant layer is formed by applying a primer treatment, and a second oil-resistant layer is formed by applying an acrylic resin-based oil resistant agent to one side of the core base paper, and the surface of the second oil-resistant layer and the liner It said a oil-resistant paper, characterized in that the oil resistant layer surface is opposed to the so stuck the in corrugating and the liner.
[0007]
Thus, according to the first aspect of the present invention, since the oil-resistant layer is interposed between the liner and the core base paper, and the liner and the core base paper are bonded together, the oil that has oozed out of the contents is removed from the liner. And is not absorbed again into the contents. Moreover, the vapor | steam which passed through the liner reaches the space between corrugated core base papers, escapes in a stepwise direction, and does not accumulate moisture in a liner. Therefore, the contents are not sticky.
[0009]
Also, oil layer, when an adhesive layer using an adhesive having oil resistance to the adhesive to stuck a liner and corrugating medium is oil component seeping from contents were absorbed into the liner, once again the contents Will not be absorbed. Even if oil penetrates into the core base paper through a pinhole or the like, it can be stopped by the adhesive portion between the opposite liner and the core base paper (double protection). Moreover, the vapor | steam which passed the liner of the side which the content contacts contacts the space between corrugated core base papers, escapes in the feeding direction, and does not accumulate moisture in the liner. Therefore, the contents are not sticky.
[0011]
In addition, since the oil-resistant layer is an oil-resistant layer formed by applying an acrylic resin-based oil-proofing agent, the oil component that has oozed out of the contents is absorbed by the liner and is not absorbed again by the contents. Moreover, the core base paper is not soaked by the oil resistant layer. Further, the vapor that has passed through the liner on the side in contact with the contents reaches the space between the corrugated core base papers, escapes in the stepwise direction, and does not accumulate moisture in the liner. Therefore, the contents are not sticky.
[0016]
The invention of claim 2 of the present invention is an oil-resistant carton produced using the above oil-resistant paper.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
