New double-bag system in Japan

An unusual double-bag system is being used for delivery of liquid for enteral nutrition in various Japanese hospitals. The system includes an aseptically filled inner Elopouch® bag, the kind often used for UHT milks.

Elopouch was developed through a strategic alliance between Elopak (New Hudson MI) and Robert Bosch (Bridgman MI) GmbH. The outer nutriBag® was designed and developed by Nutrichem of Ross Germany.

Relying on ultraclean packaging equipment Nutrichem places the filled Elopouch into the nutriBag. In use at the hospital a special fitment on the nutriBag penetrates the Elopouch releasing its liquid contents into the nutriBag. The fitment on the nutriBag also has a tube through which the liquid is delivered directly to the patient’s stomach or small intestine. Unlike glass bottles traditionally used for enteral nutrition the nutriBag is light it won’t break and it eliminates the need to fill into another container. Its cost relative to other delivery systems was not available at press time.

The 130-micron (5.1-mil) Elopouch material used for this application includes high-density polyethylene/polyester/aluminum foil/PE. The high-barrier structure provides an 18-mo nonrefrigerated shelf life for the aseptically filled product. Supplied by Elopak in Norway the Elopouch material is sent to Nutrichem as rollstock.

On a customized Elopak E-P 4000 aseptic twin-tube vertical f/f/s machine Nutrichem forms the material into pouches and fills them with the mineral/vitamin-based liquid food before heat-sealing the pouches closed. The 500-mL pouches are filled at speeds to 4/hr (67/min).
