Rubber Stoppers Bungs (electrometric closures for drug containers) are mainly used in stoppering vials and it is necessary to sterilize these as they are in direct contact with the final product. Though the trend of using pre-sterilized bungs from the market is still prevalent, their viability is still a question, owing to the various handling & transportation issues leading to questions on sterility.

Bung Processor cum steam sterilizer enables customers to reap benefits of ‘washing and sterilizing’ from single equipment. The bungs are loaded into a ‘drum’ and later placed into the sterilizer. The entire operation is done via PLC where in the pre-set program determines the wash sequence (Eg. Detergent Wash, WFI Wash & Silicon Treatment) followed by a final sterilization using HPHV cycle. This ensures complete sterility for the bungs. These bungs can later be unloaded in “sterile pouches/ bags” and transferred to the filling room, usually under laminar air flow conditions.

SILICONIZATION :

After Cleaning Closures Are Siliconized Using A Sillcone Emulsion Or Oil.Siliconization Of Closures Is Necessary To Prevent The Release Of Plasticizers And Other Coumpound Added During The Coumpounding Of Elastomeric Closures, To Prevent Any Reaction Between The Closures And The Medication Stored Or To Ensure Smooth Operation Of The Machines Used For Bunging.

STERILIZATION :

In Sterilization The Closures Are Sterilized With Steam. A Pre- Vaccum Precess Is Employed To Ensure Effective Removal Of Air And Penetration Of Steam.

DRYING :

After Sterilization The Closures Are Dried Using A Vaccum Drying Process. The Drying Efficiency Is Furter Improved By The Continuous Rotation Of The Closures. Processensures Bone Dry Closures On Unloading.

SHREE BHAGWATI has designed a unique ‘drum’ that has the capability for auto unloading of the bungs, which eliminates the intermediate ‘handling’ of bungs. Also, with expertise you can look forward to special feature like preservative & Hot Air treatment with HEPA Filters for enhanced results.

Technique used:

The stages of bung processing that will be addressed will be loading, washing with detergent, rinsing, siliconization, sterilization and drying.

Applications:

Used extensively in pharma and rubber industry
