Abstract
The present invention relates to improvements of bioreactor bags for cell cultivation. The invention provides an inflatable bioreactor bag for cell cultivation comprised of a top and a bottom sheet of polymer material that are joined along their edges to form a sealed bag, wherein two opposing edges are formed as clamping edges to allow clamping of the bioreactor bag to a rocker type bioreactor, wherein the top sheet is at least 5% longer than the bottom sheet between the clamping edges. The bioreactor bags provided by the invention avoid formation of undesired wrinkles or creases which otherwise may lead to fatigue of the plastic and eventually fracture.
