２６９８６号公報等参照）。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) This invention relates to a lid material for a container for packaging foods and the like. (Prior art and its problems) Conventionally, AI foil, Ad-deposited film, etc. have been used as lid materials for plastic containers filled with various foods (see Utility Model Publication No. 61-2040, Utility Model Publication No. 61-2040, Kosho 60-

されたものとけほど遠く高級感が得られない。In order to improve this, it is possible to apply physical stress to generate cracks in the Ag deposited layer, or to remove the ViAD deposited layer in a lattice pattern, but these are insulators for DC 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 charge caused by microwaves, and it is not sufficient for use in microwave ovens. In addition, there are cracks in the metal vapor deposited layer, and the metal is removed in a grid pattern, giving the appearance of many curved lines or straight lines. .

ことけ大きな特徴を有するもっである。This invention has an island-like structure for the metal evaporated layer, so that it has microwave transmittance, insulation properties, and beautiful metallic luster even though the metal evaporated M layer is used. It also has characteristics.

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 the loss of microwave transmission. When microwaves are irradiated to the metal vapor deposited layer, it becomes charged, causing discharge and combustion. This may cause heat generation and the film to shrink due to heat.

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 amount of metal in the whole and 1- is small, and a beautiful metallic luster cannot be obtained.

半導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 deposited layer of this invention, it is necessary to control the evaporation rate, the thickness of the 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 precious metals (which are relatively easy to control, especially Sn, p'b, and Z)
n, Bi, etc. are particularly preferred, but p'b, Zn, Bi, etc. are not so preferred considering their toxicity when used for food, and Sn is most suitable. Also, Ti, O
It is relatively difficult to control transition metals such as r, Fe%Co, and N1, and semiconductor metals such as Si and Go.

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 changes, the smaller the island size tends to be. However, the effect of the deposited film thickness is particularly large, and when the deposited film thickness is converted into light transmittance, a light transmittance of 1 or better to 154 is optimal for obtaining the island-like structure of the metal deposited layer of the present invention. However, this also varies depending on the metal.
This range is sufficient for Sn, Pb, Zn%B1, etc., but this range may not necessarily be optimal for other metals.

である。In the case of SnD, which is a typical metal used in this invention, Sn
If the light transmittance of the vapor-deposited layer is less than 1 factor, the Sn vapor-deposit layer will be charged by microwaves and may cause discharge and thermal contraction.If the light transmittance exceeds 154, no discharge or heat shrinkage will occur, but it will be beautiful. A metallic luster cannot be obtained. In order to obtain a beautiful metallic luster, the Sn vapor deposited layer requires a gloss level of approximately 650 or higher, but if the light transmittance of the SnM deposited layer is 15 coefficients or lower, the gloss level will be 350 or higher.
