Abstract (en)
[origin: WO2018007691A1] The 3-D flexible bag (1) to be filled with a biopharmaceutical product is the result of the assembling of two wall elements (2, 3) and of two gussets (11, 12). At least one connection port (4, 6) is also provided, for filling and/or emptying. A substantially parallelepipedal configuration is obtained in a filled state thanks to the unfolding of the gussets combined with the folding of flaps (21, 22, 31, 32) of the two wall elements. A transverse weld (140, 150), formed at one end, connects the two wall elements (2, 3) of the bag and extends continuously, keeping in a folded-flat state: – an elongate edge portion of one gusset (11); – an elongate edge portion of the other gusset (12). This transverse weld has a length corresponding to a determined dimension (L2) of the flexible bag in the parallelepipedal configuration.
