Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a thermoforming sheet sufficiently suppressing hole opening of a tray when cooking even when a frozen food contains a lot of oily components, and a food tray using the same.SOLUTION: A thermoforming sheet as a thermoforming sheet obtained by laminating two or more layers is such that one outermost layer in the thermoforming sheet contains crystalline polyester, and the other outermost layer contains polypropylene. In a food tray obtained by thermoforming the thermoforming sheet, the outermost layer containing crystalline polyester is positioned in a surface contacting a food.SELECTED DRAWING: None 【課題】冷凍食品が油性成分を多く含む場合であっても、加熱調理した際のトレイの穴開きが充分に抑制される熱成形用シート、及びこれを用いた食品用トレイを提供すること。【解決手段】２以上の層が積層されてなる熱成形用シートであって、該熱成形用シートにおける一方の最外層が結晶性ポリエステルを含有し、且つ他方の最外層がポリプロピレンを含有する、熱成形用シート，及び該熱成形用シートを熱成形することによって得られ、且つ結晶性ポリエステルを含有する最外層が食品と接する面に位置する食品用トレイ。【選択図】なし
