1. A bag assembly comprising:
a bag portion comprising first and second walls defining an interior and an opening, wherein the interior is formed by the first and second walls of the bag portion being attached to each other along at least a portion of a perimeter of the bag assembly up to one end of the bag portion, wherein portions of the first and second walls of the bag portion that are not attached to each other form the opening,
an aseptic system for sterile connection and disconnection of the bag assembly from a sterile process, the aseptic system being continuously formed at an interface between the aseptic system and the one end of the bag portion, and;
a fitment comprising first and second outer surfaces extending between opposing end points and a fitting extending transversely from the fitment, wherein the continuous formation at the interface is formed by the fitting of the fitment and the aseptic system being over molded with a melt-processable material to connect the aseptic system and the fitting of the fitment such that the internal passage of the aseptic system is connected to an internal passage through the fitting and the fitment to the interior of the bag portion,
