In recent years, there has been an increase in the number of cooked or semi-cooked foods that can be served on the table by simply 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 against moisture, for sealed packaging.

し、その場合も、容器をさらにラツプフイルムで
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 packaging in the above-mentioned form into a microwave oven, the contents will not 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 wrap 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、従つ

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 the bag can be used for cooking in order to save the above-mentioned time and effort.

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.

When the metal foil of the packaging bag is removed, a bag made of a synthetic resin base remains, and since this does not reflect high frequencies, it can be used as is for cooking in a microwave oven.

FIG. 1 shows a packaging material used in the packaging bag of the present invention. As shown in the figure, the packaging 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 protective layer 7 on the outer surface of the metal foil 6. This layer 7 is formed by coating with a synthetic resin or bonding a synthetic resin film.
上記基材２には、ポリエステル、ナイロン（商

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 the pattern is dotted, linear, or grid-like as shown in FIG. 2 A, B, and C. etc., any of the above is fine. 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
離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. 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
を除く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 made with the heat sealing layer 3 on the inside,
Fold it in half and stack it on top of each other, making the crease 11 at the periphery.
The bag 10 is completed by heat-sealing the bag on three sides except for the 3 sides to form a heat-sealed portion 12 as shown by the chain line. 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
全周にわたつて熱封緘し、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 thereof.
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に沿つて、包装

レンジに入れて調理すればよい。 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. 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. bag 1
When the metal foil 6 is peeled off from the back side of 0 in the same way,
A bag made of 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

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 sufficiently withstand handling such as distribution and storage. It is possible to prevent the contents from deteriorating in quality, and since the metal foil is made 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
