PACPAL Roto Fill

The Claudius Peters range of products offers rotary packers with up to 16 spouts and in-line packers with a maximum of 4 spouts. The size of the packer is mainly determined by the packing capacity and the available space for the plant.

Customer benefits:

  • Modular designs
  • Integrated independent weighing systems
  • Components easily exchangeable
  • Extendable circumference
  • Low maintenance cost
  • Dust diversion directly at the spout
  • Dedusting in the packer head
  • Almost dust free operation
  • Horizontally rotating turbine
  • Vertically rotating turbine


Turbine or Air

Depending on the existing bulk material different filling systems can be used with both packing machines. Turbine packers are well proven in applications where bulk materials are capable of flowing and have a maximum grain size. For materials with variable flow properties and grain sizes of more than 4 mm (for example specialist building materials) compressed air filling systems are more suitable. Both turbine and air systems comply fully with modern bagging technology.

  • Realisation of the EC-directive OIML R 61

Ultrasonic bag sealing “Absolutely dust tight”

Claudius Peters has developed ultrasonic welding technology for bag valves to conform to the stringent requirements for cleanliness, when storing and handling individually packed bulk materials.

Here the valve is sealed hermetically and is dust-tight following the filling of the bag. The special valves are internally coated with a fusible synthetic material. For welding the valve is clamped between the sonotrode and the anvil. At the same time a generator is
creating ultrasonic vibrations which are transmitted to the fixed valve by the sonotrode. The heat arising from the ultrasonics forces the synthetic material to melt and the valve is glued. Subsequently the bag is fed to the bag discharge.


  • Locking rates almost 100%
  • Shortest locking times
  • Sealing directly at the module
  • Maintenance friendly structure
  • Protects the filled material from moisture and environmental impact
  • Subsequent plant components remain clean
