【発明の詳細な説明】 産業上の利用分野 本発明は、いろいろな食品に対して多目的に利用で
き、食品の味、風味、表面状態の変化が少ない包装材料
に関する。Description: FIELD OF THE INVENTION The present invention relates to a packaging material which can be used for various purposes for various foods and which has little change in taste, flavor and surface state of foods.
従来の技術 アルミニウム箔は、通気性が無い、包み易い、遮光性
が高い等の性質に加え、外観が美しい点で食品の包装材
料として広く用いられている。2. Description of the Related Art Aluminum foil is widely used as a food packaging material because it has no air permeability, is easy to wrap, has high light-shielding properties, and has a beautiful appearance.
しかし、アルミニウム箔は水や油を吸収する性質がな
く、また、破れ易い欠点がある。そこで、これらの欠点
を補うために、アルミニウム箔と紙とを積層する技術が
知られている。However, aluminum foil does not have the property of absorbing water or oil, and has the disadvantage that it is easily broken. Therefore, a technique of laminating aluminum foil and paper to compensate for these drawbacks is known.

It is described that free cut paper is used to prevent oil from penetrating into fried foods such as tempura and prevent dirt on a serving plate.
しかしながら、これらの積層シートでは吸水能力が不
十分であったり、あるいは、いろいろな食品に対して多
目的に利用できないという問題があった。However, there has been a problem that these laminated sheets have insufficient water absorbing ability or cannot be used for various purposes for various foods.
例えば、従来の積層シートを用いて、おにぎりやサン
ドイッチを包装すると、食品表面が“べとついたり”、
海苔の風味が損なわれたりする。For example, if you use traditional laminated sheets to package rice balls and sandwiches, the food surface will be "sticky",
The flavor of the laver is impaired.
また、肉や魚を包んで冷凍保存し、冷凍庫より取り出
した直後に包装シートを剥すと、紙が食品上に残るとい
う問題があり、冷凍保存時の包装シートとしては適当で
ない。Further, if the meat or fish is wrapped and stored frozen, and the packaging sheet is peeled off immediately after being taken out of the freezer, there is a problem that paper remains on the food, which is not suitable as a packaging sheet for frozen storage.
発明が解決しようとする課題 本発明は、吸水性が高く、いろいろな食品に対して多
目的に利用できる食品包装シートを提供するものであ
る。Problem to be Solved by the Invention The present invention is to provide a food packaging sheet having high water absorption and being versatile for various foods.

もよい。As the paper 13, the smoothness of at least the surface side 13a is measured by a Oken type smoothing meter [J. TAPPI paper pulp test method No. 5
m-14 "Test method for smoothness and air permeability of paper and paperboard using air micrometer type tester" B. Method using Oken type smoothness and air permeability tester (pressurized type)] for 500 seconds or more, preferably Is 1
Paper of 000 seconds or more is used. If the smoothness of the surface side is less than 500, the peelability between the food and the paper at the time of opening the package after the frozen storage is poor, and there is a practical problem. Specific examples of such paper 13 include glassine paper and imitation paper having high smoothness. The smoothness of the back surface 13b of the paper 13 (adhesive surface with the aluminum foil 11) may be 500 seconds or less.

封後の食品の“べたつき”を防止できる。Also, the adhesive portion between the paper 13 and the aluminum foil 11
It is necessary to make 15 to 50%, preferably 20 to 40% of the 11,13 interface. Referring to FIG. 2, the area of the bonded portion 17 occupies 15 to 50% of the total area of the interface, that is, the bonded portion 17 and the non-bonded portion 19. When the bonding portion between the aluminum foil 11 and the paper 13 exceeds 50%, the water absorption capacity decreases, while
%, The releasability between food and paper during frozen storage deteriorates. Further, as shown in FIG. 2, the unbonded portion 19 is desirably continuous over substantially the entire area of the food packaging sheet without being surrounded by the bonded portion 17. As a result, the absorbed water can be diffused into the unbonded portion 19 by capillary action. "Stickness" can be prevented.

装シートが得られる。Effect of the Invention According to the present invention, the advantage of a packaging material of an aluminum foil is lost by partially bonding and integrating a paper having specific smoothness and an aluminum foil to form a packaging sheet. Thus, a highly versatile food packaging sheet which is excellent in oil absorption and water absorption and can be used for various purposes for various foods is obtained.

した直後に包装シートを剥しても、シートが食品上に付
着して残存することが防止される。For example, when a sandwich or onigiri is wrapped with the packaging sheet of the present invention, it is possible to prevent the food surface from being “sticky” after opening and losing the flavor of nori or the like. Further, even if the food is wrapped, stored frozen, and the packaging sheet is peeled immediately after being taken out of the freezer, the sheet is prevented from adhering and remaining on the food.

た。The bonding pattern by the adhesive was as shown in FIG. 2, and the dimensions were A = 15 mm, B = 5 mm, C = 5 mm, and D = 4 mm in FIG. At this time, the bonded portion occupies 27% of the interface between the aluminum foil and the glassine paper. As an adhesive, a mixture of a polyester polyol and a polyurethane polyisocyanate was used so that a total of 0.7 g / m 2 was applied.
