The present invention relates to a method and system for aseptically filling of flexible packages containing dry cloth. Such a method may include a first stage that is performed in a non-sterile environment. The first stage may include cutting a first substantially dry cloth to a predetermined size; inserting the first cloth into a flexible package; sealing a first end of the flexible package; and sterilizing the flexible package. The method may also include a second stage performed in a sterile environment. The second stage may include filling the flexible package with a medical solution such that the substantially dry cloth absorbs at least a portion of the medical solution; and sealing the an open end of the flexible package.
