ましい。The high nitrile resin used in the present invention is a copolymer mainly composed of unsaturated nitrile such as acrylonitrile and methacrylnitrile, and has an unsaturated nitrile content of 50% by weight or more. Examples of monomers to be copolymerized include styrene, butadiene, isoprene, methyl acrylate, ethyl acrylate, methyl methacrylate, and ethyl methacrylate, and one or more of these is copolymerized with unsaturated nitrile. In addition, high nitrile resins include mixtures with rubber-like polymers such as butadiene-acrylonitrile copolymer rubber, isoprene-acrylonitrile copolymer rubber, butadiene-styrene copolymer rubber, polybutadiene, polyisoprene, and rubbery polymers thereof. A mixture of an unsaturated nitrile and the above monomer copolymerized in the presence of a polymer may also be used. Particularly preferred is one produced by polymerizing acrylonitrile and other monomer components in the presence of a diene-based synthetic rubber, since it has good impact resistance.
高ニトリル樹脂には酸化防止剤、紫外線吸収剤、帯電防
止剤、滑剤、結晶核剤等の添加剤、着色顔料や炭酸カル
シウム、タルク、硫酸バリウム等の無機充填剤を含んで

トレーの苫フィルムは、−軸又は二輪延伸した高ニトリ
ル樹脂フィルムが用いられる。蓋フィルムの厚みが大き
くなるとトレー状の蓋になるが、この態様も本発明に含
まれる。A high nitrile resin film subjected to -axis or two-wheel stretching is used as the ink film of the tray. When the thickness of the lid film increases, the lid becomes a tray-like lid, and this embodiment is also included in the present invention.
この高ニトリル樹脂フィルムは単層又は異なる機能を付
与した高ニトリル樹脂フィルム、若しくは他の合成樹脂
