〈産業上の利用分野〉
本考案は食品を包装するマイクロ波発熱シート
に関し、特にマイクロ波加熱により食品の表面に
こげ目を付けるマイクロ波発熱シートに関する。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a microwave heating sheet for packaging food, and particularly to a microwave heating sheet for browning the surface of food by microwave heating.
〈従来技術とその問題点〉
従来よりマイクロ波発加熱により食品に焦げ目

目を付ける方法は、特公昭60−15548号公報に示
されているように広く知られている。<Prior art and its problems> Various methods of browning foods using microwave heating have been tried in the past, and in particular, methods of bringing food into contact with a microwave heating element made of a laminate including a thin film layer of metal vapor deposition have been attempted. A method of browning the contact area is widely known as shown in Japanese Patent Publication No. 15548/1983.

生してしまつて、マイクロ波発熱シートを焦げ目
を所望する食品に密着させても、やはり焦げ目の
ムラが発生してしまうという欠点があつた。 However, depending on the food to be heated, the heating method, etc., if the contact between the microwave heating element and the food is poor, it takes a long time to brown the food, and there are drawbacks such as uneven browning. Also, for browning, add a thin layer of metal evaporation to approx.
It must be formed to a thickness that has an electrical resistivity of Ω/square inch (approximately 700 Å or less if the metal used is aluminum), and to form such a thickness by vacuum deposition, it is usually evaporated. Because the base film is fed at high speed, it is difficult to precisely control its thickness, resulting in uneven vapor deposition. The drawback is that it can occur.
〈解決しようとする問題点〉
本考案は上記問題点を解決しようとするもので
あり、簡単な構成で、マイクロ波加熱により短時
間で焦げ目を付けることが可能で焦げ目のムラの
発生しないマイクロ波発熱シートを抵供するもの
である。<Problems to be Solved> The present invention attempts to solve the above-mentioned problems.It has a simple configuration, can be browned in a short time by microwave heating, and does not cause uneven browning. It provides a heat generating sheet.
〈問題点を解決するための手段〉
食品を基材物質に金属蒸着の薄膜層を有する耐
熱性収縮フイルムを積層してなるマイクロ波発熱
シートで包装してマイクロ波加熱をすることで解
決した。<Means for solving the problem> The problem was solved by wrapping the food in a microwave heating sheet made by laminating a heat-resistant shrink film having a thin metal-deposited film layer on a base material and heating the food with microwaves.
〈作用〉
収縮フイルムが収縮するとマイクロ波発熱シー
トが食品と密着する。<Operation> When the shrink film contracts, the microwave heating sheet comes into close contact with the food.
しかし金属蒸着の薄膜層の金属は殆んど収縮し
ないのでその粒子の密度が収縮前に比べて密にな
り蒸着ムラも少なくなる。 However, since the metal in the thin film layer of metal vapor deposition hardly shrinks, the density of its particles becomes denser than before shrinkage, and the unevenness of vapor deposition becomes less.
〈実施例〉 本考案を図面を用いて詳細に説明する。<Example> The present invention will be explained in detail using the drawings.

ートＡである。 FIG. 1 is a cross-sectional view of one embodiment of the present invention, which is a microwave heating sheet A in which a shrinkable polyester film 1 having a 30 Å aluminum vapor-deposited layer 2 is laminated on a paper 3. This is a microwave heating sheet A provided with fixing portions 4 that are partially fixed in the pattern shown in FIG.

ルム１の収縮を容易にさせることができるばかり
でなく、収縮時に剥離するのも防止できる。 When this microwave heating sheet A is shrunk, a shrinkable polyester film 1 is formed as shown in FIG.
The part shrinks, but since the aluminum in the aluminum vapor deposited layer 2 hardly shrinks, the density of the particles becomes denser, and the paper 3 also hardly shrinks, so the parts are fixed in a fixed pattern rather than the entire surface. It is preferable to do so. With such a configuration, wrinkles occur in the paper 2 as the base material when the shrinkable polyester film 1 shrinks, but it not only makes it easier to shrink the shrinkable polyester film 1, but also prevents it from peeling off when shrinking. can also be prevented.
ここで前記実施例で基材物質を前記収縮性ポリ
エステルフイルム１と同厚み、同収縮率の収縮性

要もない。 Here, in the above embodiment, if a shrinkable polyester film having the same thickness and the same shrinkage rate as the shrinkable polyester film 1 is used as the base material, there is no need for partial fixation.

コーンが得られる。 FIG. 3 shows a cross-sectional view of the microwave heating sheet A of the present invention used in sweet corn with a cob 5,
By shrinking, it adheres closely to the corn part, so that sweet corn with browned marks can be obtained by microwave heating.
このように食品の包装材料としての用途に用い
