この発明は、食品等を収納して、電子レンジで調理可能
な包装袋に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a packaging bag for storing foods and the like, which can be cooked in a microwave oven.
近年、電子レンジなどで再加熱するだけで、食卓に供す
ることができる調理済或は半調理済食品が増加しており
、このような食品の味や品質の劣化を防ぐため、光や空
気、水分など（こ対してバリヤー性の優れたアルミニウ
ム箔などの金属箔を用いた包装材料で密封包装するのが
一般的である。In recent years, there has been an increase in the number of cooked or semi-cooked foods that can be served on the table simply by reheating them in a microwave oven, etc. In order to prevent the taste and quality of such foods from deteriorating, it is necessary to protect them from light, air, etc. It is common to use packaging materials that use metal foil, such as aluminum foil, which has excellent barrier properties to prevent moisture, etc.
しかしながら、金属箔は、高周波を反射してしまうため
、上記のような包装形態のものをそのま＼電子レンジに
投入しても、内容物を加熱することができず、また電子
レンジ自体の故障の原因にもなるため、包装袋を開封し
て内容物を取り出し、他の容器に移し換えて加熱してい
る。しかし、その場合も、容器をさらにラップフィルム
で包む必要があり、非常に面倒である。However, metal foil reflects high frequency waves, so even if you put the above-mentioned packaging into a microwave oven, the contents cannot be heated, and the microwave oven itself may malfunction. To avoid this, the packaging bag is opened, the contents are removed, and the contents are transferred to another container and heated. However, even in that case, it is necessary to further wrap the container with cling film, which is very troublesome.
そこで、この発明の目的は、上記のような手間を省くた
め、金属箔を除去することができ、従って袋のま＼で調
理可能な包装袋を提供することである。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a packaging bag in which the metal foil can be removed and, therefore, cooking can be carried out in the bag, in order to save the above-mentioned time and effort.
上記の目的を達成するため、この発明は、合成樹脂基材

装袋において、上記接着剤層を間欠的に設けるか、又は
接着強度を弱くして上記金属箔を基材から手で剥離可能
としたのである。In order to achieve the above object, the present invention laminates a heat-sealing layer on the inner surface of a synthetic resin base material and a metal foil on the outer surface with an adhesive layer interposed therebetween, and heat-seals the heat-sealing layers on the inner surface with each other. In the sealed packaging bag, the adhesive layer is provided intermittently or the adhesive strength is weakened so that the metal foil can be manually peeled off from the base material.
上記包装袋の金属箔を取り去ると、合成樹脂基材から成

電子レンジで調理することができる。When the metal foil of the packaging bag is removed, a bag made of synthetic resin remains, which does not reflect high frequencies, so it can be used as is.
Can be cooked in the microwave.

り合せなどによって形成する。FIG. 1 shows a packaging material used in the packaging bag of the present invention. As shown in the figure, the wrapping material 1 is made by laminating a heat sealing layer 3 on the inner surface of a synthetic resin base material 2 and a metal foil 6 such as aluminum on the outer surface with an intermittent adhesive layer 4 interposed therebetween. Note that it is preferable to provide a surface protection layer 7 on the outer surface of the metal foil 6. This layer 7 is formed by coating with synthetic resin or bonding a synthetic resin film.

用いられる。The base material 2 includes polyester, nylon (trade name),
Polypropylene and the like are preferred, and they may be used alone or in composite form. Also, for heat sealing @3,
Polyolefin, ethylene-vinyl acetate copolymer, etc. are used.
上記間欠的接着剤層４は、接着剤のパートコートによっ

部に沿って、接着剤を塗布しない帯状の部分、即ち接着
剤欠除帯５を設けておくのがよい。The intermittent adhesive layer 4 is formed by part-coating adhesive, and its pattern is shown in FIG.
As shown in (a), (b), and (i), it may be dotted, linear, grid-like, etc. Furthermore, for the purpose described later, it is preferable to provide a band-shaped part to which no adhesive is applied, that is, an adhesive-free band 5, along the unsealing part.
上記包装材１には、包装袋に形成したとき、袋の外周か
ら突出するタブ８を形成しておくことができる。この機
能についても後述する。なお、この場合には、上記の接
着剤欠除帯５を省略することができる。The packaging material 1 can be provided with a tab 8 that projects from the outer periphery of the bag when it is formed into a packaging bag. This function will also be described later. In addition, in this case, the above-mentioned adhesive cutout zone 5 can be omitted.
上記接着剤層４の接着強度が金属箔６を手で剥葭できる
程度に弱い場合には、第３図に示すように、接着剤を全
面に塗布した層４を形成してもよい。但し、接着剤欠除
帯５には塗布しない。If the adhesive strength of the adhesive layer 4 is so weak that the metal foil 6 can be peeled off by hand, the layer 4 may be formed by coating the entire surface with adhesive, as shown in FIG. 3. However, it is not applied to the adhesive missing zone 5.
第４図は、上記のような包装材１を用いて形成した包装
袋の一例を示す。FIG. 4 shows an example of a packaging bag formed using the packaging material 1 as described above.
まず、包装材１を、熱封緘層３を内面にして、２つ折り
にして重ね合せ、その周縁部の折目１１を除（３方を熱
封緘して、鎖線で示すような熱封緘部１２を形成すると
、袋１０が出来上る。勿論、内容物は、袋１０の内部に
封入されている。First, the packaging material 1 is folded in half with the heat-sealing layer 3 on the inside, and the folds 11 at the periphery are removed. , the bag 10 is completed.Of course, the contents are sealed inside the bag 10.
袋１０の形成方法は、上記に限らない。例えば、２枚の
包装材１を重ね合せて、その周縁部を全周にわたって熱
封緘し、包装袋１０を形成してもよい。The method of forming the bag 10 is not limited to the above. For example, the packaging bag 10 may be formed by overlapping two packaging materials 1 and heat-sealing the entire periphery of the packaging material 1.
この包装袋１０を調理に供するには、まず、第４図の点
線で示す接着剤欠除帯５に沿って、包装袋１０を切断す
る。この切断した端部においては、接着剤層４が無いの
で、金属箔６と基材２は分離しており、金属箔６を手で
つまむことができる。In order to use the packaging bag 10 for cooking, the packaging bag 10 is first cut along the adhesive cutout zone 5 shown by the dotted line in FIG. Since there is no adhesive layer 4 at this cut end, the metal foil 6 and the base material 2 are separated, and the metal foil 6 can be pinched by hand.
そこを手がかりとして金属箔６を表面保護層７と共に引
張ると、基材２から剥離される。袋１０の裏面も、同様
にして金属箔６を剥離すると：合成樹脂基材２から成る
袋が残る。この袋を電子レンジに入れて調理すればよい
。When the metal foil 6 is pulled along with the surface protective layer 7 using this as a clue, it is peeled off from the base material 2. When the metal foil 6 is peeled off from the back side of the bag 10 in the same way: the bag made of the synthetic resin base material 2 remains. Just put this bag in the microwave and cook.
また、タブ８が設けられている場合には、タブ８の先端
で、基材２と金属箔６を分離させ（特に第１図のような
間欠的接着剤層４であれば、容易に分離する）、金属箔
６を引張って剥離すればよい。In addition, if the tab 8 is provided, the base material 2 and the metal foil 6 can be separated at the tip of the tab 8 (particularly if the adhesive layer 4 is intermittent as shown in FIG. 1, the separation is easy). ), the metal foil 6 may be pulled and peeled off.
この発明の包装袋は、以上のように、合成樹脂基材と金
属箔との積層体より成るから、強靭でバリヤー性に優れ

にも、金属箔を取り去るだけで、そのま＼用いることが
できる。As described above, since the packaging bag of the present invention is made of a laminate of a synthetic resin base material and metal foil, it is strong and has excellent barrier properties, and can withstand handling such as distribution and storage. In addition, it is possible to prevent the contents from deteriorating in quality, and since the metal foil is removable, it can be used as is for cooking in a microwave oven by simply removing the metal foil.
即ち、この発明の包装袋は、流通、保管、調理に至るま
