ともあった。However, when a conventional A4 vapor-deposited film is heated and cooked in a microwave oven, the electric charge generated by the microwaves in the Al vapor-deposited layer causes discharge, heat generation, and thermal contraction. This discharge could cause combustible materials such as paper and plastic to burn.

化された包装材とはほど遠く高級感が得られない。In order to improve this, there are books that apply physical stress to generate cracks in the Al deposited layer, or remove the Al deposited layer in a lattice pattern, but these methods are similar to insulators in direct current resistance. Although it exhibits a large surface resistance, it is difficult to process it into a surface area so fine as to eliminate the amount of electrostatic charge caused by microwaves, and it is not sufficient for use in microwave heating and cooking. In addition, these materials have cracks in the metal vapor deposition layer or have metal removed in a lattice pattern, giving the appearance of many curved lines or straight lines, which is far from a packaging material that is beautifully metallized all over, and does not give a sense of luxury. do not have.

However, of course, other plastic films, paper, cellophane, etc. may be laminated as appropriate, or an appropriate resin layer may be coated. A protective layer may be provided on the metal vapor deposited layer, and the present invention is free to provide appropriate printing at appropriate locations, and such materials are also included in the present invention. Further, in the present invention, a portion of the metal vapor deposited layer may be removed by etching or the like, and an appropriate pattern, design, etc. may be formed in the metal vapor deposit layer or a portion where the metal vapor deposit layer does not exist.

うに設ける。The metal vapor deposition layer is provided so as to form an island-like structure after passing through "nucleation", "nuclear bonding", and "initial island-like structure" in the thin film production process.

性、絶縁性、及び美麗な金属光沢性を有するようにした
ことに大きな特徴を有するものである。The major feature of this invention is that by forming the metal evaporation layer into an island-like structure, it has microwave transparency, insulation properties, and beautiful metallic luster even though the metal evaporation layer is used. It has the following.
島状構造における島のサイズは２００ Å〜１μｍ程度

が照射すると電荷が帯電し放電や燃焼が生じたりあるい
け発熱しフィルムが熱収縮する。The size of the islands in the island-like structure is approximately 200 Å to 1 μm. If the island size is smaller than 20OA, beautiful metallic luster cannot be obtained. When the size of the islands exceeds 1 μm, the islands come into contact with each other and become a single unit, resulting in a decrease in insulation and impermeability of microwaves.When microwaves are irradiated to the metal vapor deposited layer, it becomes electrically charged, causing discharge and combustion. Heat is generated and the film shrinks due to heat.
島の間隔け１００Å〜５０００ Ａとする。島の間隔が
１００Ａより小さいと帯電した電荷のトンネル電流が流

島の間隔が５００ＯＡより大きいと全体としての金属の
量が少なく美麗な金属光沢は得られない。If the spacing between the islands is larger than 500 OA, the overall amount of metal will be small and beautiful metallic luster will not be obtained.

体金属は制御は比較的容易でない。In order to obtain the island-like structure of the metal vapor deposited layer of this invention, it is necessary to control the evaporation rate, the thickness of the vapor deposited film, etc. Controlling the size and spacing of the islands in this invention may be difficult depending on the metal used. Generally speaking, metals with low melting points and noble metals are relatively easy to control, especially Sn, Pb, Zn,
Bi and the like are particularly preferred, but considering the toxicity when used for food, PB, Zn, Bi, etc. are not so preferred, and Sn is most suitable. Also, Ti, Or%F
Control of transition metals such as e, Co, and N4 and semiconductor metals such as Si and Ge is relatively difficult.

他の金属では必ずしもこの範囲が最適とはならない場合
もある。The generation of the metal vapor deposited layer with the island-like structure of this invention involves controlling the relationship between the cohesive energy and adsorption energy of the metal, and therefore requires control of various vapor deposition conditions. The faster the evaporation rate, the smaller the island size tends to be. However, the influence of the deposited film thickness is particularly large, and when the deposited film thickness is converted into light transmittance, a light transmittance of 1% to 15 cm is optimal for obtaining the island-like structure of the metal vapor deposited layer of the present invention. However, this varies depending on the actual metal.
This range may be sufficient for Sn, Pb, Zn, Bi, etc., but this range may not necessarily be optimal for other metals.

である。In the case of Sn, which is a typical metal used in this invention, Sn
If the light transmittance of the vapor-deposited layer is less than 1, the Sn vapor-deposit layer will be charged by microwaves and may cause discharge or thermal contraction.If the light transmittance exceeds 15, no discharge or thermal contraction will occur, but it will be beautiful. A metallic luster cannot be obtained. In order to obtain a beautiful metallic luster, a Sn vapor deposited layer generally requires a gloss level of 350 or higher, but if the light transmittance of the Sn vapor deposited layer is 15 coefficients or lower, the gloss level will be 350 or higher.
