To provide a molded bale of a rubber composition that prevents a molding die from being contaminated, prevents the rubber composition from rising in viscosity with time, prevents the rubber composition from peeling off from the molded bale, and facilitates the adhering of a packaging sheet to the molded bale.SOLUTION: A molded bale of a rubber composition contains: a rubber-like polymer (A) having an iodine value of 10 to 250, 3 mass% or more of an ethylene structure, and less than 10 mass% of a vinyl aromatic monomer block; and titanium (C), in which a content of the titanium (C) is 3 ppm or more and 120 ppm or less, and a content of aluminum (B) is less than 2 ppm.SELECTED DRAWING: None

    【課題】成形金型が汚染し難く、ゴム組成物が経時で粘度が上昇し難く、ベール成形体からゴム組成物が剥離し難く、ベール成形体に包装シートが密着し易いゴム組成物のベール成形体を得る。【解決手段】ヨウ素価が10~250であり、エチレン構造≧3質量%であり、かつ、ビニル芳香族単量体ブロック<10質量%であるゴム状重合体(A)と、チタン(C)とを含有し、3ppm≦チタン(C)の含有量≦120ppmであり、アルミニウム(B)の含有量が、2ppm未満であるゴム組成物のベール成形体。【選択図】なし
