A bag for bulk material is formed of sleeve material, which is sleeve planar material or flat material connected into a sleeve, formed by fabric, non-woven material, film or paper. In this case, the bag has the first open end and the second open end, which are opposite to each other. Moreover, sections of sleeve material of at least one of open ends are formed by folding into a bag bottom. At the same time, the bag bottom has the first cover sheet, which is made to strengthen the bag bottom. In this case, the bag bottom has the second cover sheet. Moreover, the first cover sheet is connected to the bag bottom and spreads in the first area of the bag bottom, and moreover, the second cover sheet is detachably connected to the bag bottom and spreads in the second area of the bag bottom. At the same time, thanks to cover sheets, folded sections of sleeve material are held together in such a way that the bag bottom is closed. The group of inventions also relates to a method and a device for making such a bag.
