ASEPTIC FILLING WITH BLOW FILL SEAL TECHNOLOGY
Rommelag’s bottelpack machines are capable of manufacturing up to 34,000 containers an hour in a wide variety of forms and plastic blends, with filling volumes ranging from 0.04 to 10,000 ml, aseptically, and taking all the applicable pharmaceutical regulations into account. Sounds good, you say? That’s what our customers say, too, and they enjoy the flexibility, precision, reliability, and virtually unlimited scope of BFS technology.

BFS: ASEPTIC PROCESSING FROM FILL TO FINISH
Every BFS process begins with the extrusion of a sterile polymer tube within the machine. The container is then instantly molded, filled, sealed, and demolded – all in a single process, in an enclosed system, and without any external intervention. This eliminates expensive logistics for and the time-consuming cleaning and sterilization of prefabricated containers.
All the filling processes including the dosing system are designed with CIP/SIP in mind. As such, all the product-handling lines are cleaned, sterilized with pressurized steam, and dried with sterile-filtered air by automatic programs. This makes bottelpack technology the most reliable aseptic filling method.
EXTRUSION
The plastic tube extruded from the granules is fed into the opened blow mold
MOLDING The main mold closes, sealing the base in the process. The mandrel is lowered onto the neck of the mold and uses compressed air to blow the tube section into the container shape. Small containers are molded with a vacuum.
FILLING
The container is filled with the precise product amount as measured by the dosing system, again via the mandrel.
SEALING
The mandrel is removed, the head mold closes, and the required closure is formed by a vacuum.
DEMOLDING
The blow mold opens, the container leaves the machine, and the next cycle begins. A conveyor system takes the container to the next processing stage
