Sterile Closures in Beta Bags

West stoppers or seals are supplied in a sterile Tyvek and multi-layered polyethylene film bag with a 110mm or a 190mm beta port. The beta port connects to an alpha port in your filling line, providing quick transfer of sterile packaging components into an aseptic filling line.

Beta Bag Material Details

Tyvek 1073B packaging material, a DuPont product, is globally recognized as a standard of excellence for sterile packaging due to its capability to enable steam to quickly penetrate and escape the packaging system, while providing a durable and robust bacterial barrier.

Polyethylene films are a commonly used material for packaging parenteral packaging components due to their ability to maintain package integrity and ensure chemical compatibility.

Beta Bag Packaging Details

The filled single-use port bag is placed into a foil secondary bag followed by a nylon tertiary bag, before being placed into a carton with an added air pad.
