Stickpack filling- and sealing machine

High-precision dosing into Stickpacks


  • Pharmaceutical industry
  • Chemicals industry


    e.g. vaccines, reagents, analysing liquids…
    e.g. pharmaceutical powders…
    e.g. pharmaceutical products, micro tablets…


This system is mainly developed to control the net weight of a Stickpack by leaving out the influence of the weight of the wrapping material.

To this end, empty bags are put into carriers - manually or supplied by a MERZ packaging machine.

The filling and weighing of the bags is performed in several steps. The filled Stickpack carriers are being conveyed step by step via a transport system.

1. Step:    The empty bag is weighed together with the carrier (tara)
2. Step:    Dosing or rather filling of product 1
3. Step:    Weighing of product 1
4. Step:    Horizontal sealing product 1    (Option for separation of product 1 and product 2)
5. Step:    Dosing or rather filling of product 2
6. Step:    Weighing of product 2
7. Step:    Horizontal sealing (closing of Stickpack)
8. Step:    Waiting position (reserve position    e.g. for control by camera)
9. Step:    Sachet sorting into good and bad bags     with reject verification
10. Step    The empty carrier moves on, back to the starting position
