1. A flexible bioprocess bag comprising:
a number of flexible panels which are sealed to each other such that when the bag is filled they form at least a bottom of the bag and a side surface of the bag;
wherein one of the number of flexible panels is called a bottom panel, said bottom panel is a continuous single elongated panel comprising an essentially quadrilateral middle part having two opposite first side edges substantially the same length as a diameter of a cylinder substantially matching the form of the side surface of the bag when the bag is filled, said bottom panel further comprising two essentially triangular parts connected one to each of the first side edges of the middle part;
wherein said essentially triangular parts are connected along their bases one to each of said first edges of the middle part with the tops of the triangular parts pointing away from each other;
wherein the two first side edges of the middle part where the bases of the essentially triangular parts are connected are shorter than two remaining side edges, called second side edges of the middle part and the two second side edges are curved such that a circle having the same diameter as a cylinder substantially matching the form of the side surface of the bag when the bag is filled still fits inside the middle part; and,
when the bag is filled said bottom panel will constitute the bottom of the bag and parts of the side surface of the bag, said parts of the side surface being bent side parts of the bottom panel.
