The present invention relates to pharmaceutical fluids, and more particularly to a flexible container for aseptic transfer and/or mixing of pharmaceutical fluids. A biocontainer for the transfer of pharmaceutical fluids includes a flexible layer divided by a fold line into a front face and a rear face. The layer is folded about the fold line such that the front face and the rear face are facing each other to define an interior space between them. The biocontainer also includes a seam that connects the front and rear faces to each other to close the interior space. A fill port is also provided to communicate with the interior space. This fill port is intersected by the fold line.
