じ、印刷面の美観を損なったり、さらには包装材料の劣
化を招く原因となっていた。Conventionally, when a paper container with air permeability is coated or laminated with polyethylene, etc., the air permeability deteriorates. Oil penetrates the outer paper through the micropores, causing stains and dirt, which impairs the aesthetic appearance of the printed surface and further causes deterioration of the packaging material.

。The present invention solves these drawbacks by adding a paper layer treated with a water/oil repellent as an intermediate layer, thereby providing a packaging container that is breathable, moisture-proof, and waterproof.

順序でラミネート構成した材料で内面にヒートシール材
層１が位置するように容器本体を形成する。To explain one embodiment of the present invention in detail with reference to drawings, as shown in Fig. 1, a heat sealing material layer is formed by forming a pattern coat or a continuous film in a lattice shape in advance, and then performing fine perforations. 1. Paper layer 2 treated with an oil and water repellent treated with a phosphoric acid fluorine oil repellent and a special styrene resin or a zirconium water repellent agent without forming a continuous film; A container body is formed of a material in which the untreated paper layer 3 is laminated in the order of heat sealing material layer 1, treated paper layer 2, and paper layer 3 so that heat sealing material layer 1 is located on the inner surface.
次に容器本体と同材質のラミネート材によりヒートシー
ルとして蓋閉めを行なう（第２図参照）。Next, the lid is closed by heat sealing with a laminate material made of the same material as the container body (see Figure 2).
また蓋に関しては、ヒートシール材４を施したフィルム
５又は紙材を用いてヒートシールすることも可能である
（第３図参照）。As for the lid, it is also possible to heat seal it using a film 5 or paper material coated with a heat sealing material 4 (see FIG. 3).

はじき、印刷等が施された紙層３に達することがない。The present invention has the above-mentioned structure, and the heat sealing material layer 1 is provided with micropores to maintain air permeability, and the intermediate treated paper layer 2 is treated with water and oil repellent treatment. Therefore, water and oil from the contents passing through the heat sealing material layer are repelled and do not reach the paper layer 3 on which printing or the like is applied.
また逆に外部からの水分等の透過を防ぐのはいうまでも
ない。Needless to say, it also prevents moisture from permeating from the outside.
さらに外層である紙層３は未処理であるため一般の紙カ
ップと同様に印刷適性が良好である。Furthermore, since the paper layer 3, which is the outer layer, is untreated, it has good printability like a general paper cup.

０〜１５０℃で乾燥させて撥水・撥油性をもたせる。To further explain the present invention, it is made by mixing an emulsion of a fluorine phosphate oil repellent and a special styrene resin water repellent or a zirconium complex salt-wax water repellent with water and an alcohol such as isopropyl alcohol or methanol. Treat one side of the base paper made of paper or paperboard,
Dry at 0 to 150°C to make it water and oil repellent.

パターンコートスル。Next, a heat-sealing material is applied to the treated surface of the base paper.As the heat-sealing material has a water- and oil-repellent effect on the base paper, it is preferable to use a hot-melt type that also serves as a coating rather than solvent-based or emulsion-based resins. Coat through a continuous thin film or pattern as thin layers as required for strength.
連続薄膜は特殊コロナ放電処理又は機械的な加工により
穿孔を行なうが、その程度は紙及び内容物との関連によ

。Water and oil repellency treatment of base paper can be done on-machine such as internal addition method, size press, and calendar coating, but it can also be done off-machine using roll coating, gravure coating, spray coating, etc.
It is possible to use a general coating method such as air knife coating.
