Small Scale: The small batch machine for micro-dosing powder into inhalation blisters (intermittent)


The SSP2 forms, fills and seals blister strips and allows a fully-automatic production. Filling can be done alternately either via drum dosage to partially fill cavities or via membrane dosing for complete filling. The blister packaging can be customized as wound double strips or sheared single strips, mounted by down-stream machines and then finally packaged.

  • Separate production area with good accessibility
  • Integrable containment for operator protection while processing highly-active and toxic products
  • Continuous inspection of the product quality
  • Ease of use and easy maintenance
  • Compact design with minimal set-up space
  • Video

    SSP2 is a DPI machine designed to manufacture dry powder blisters in small batch standard.

  • SSP2 – Micro-dosing powder for inhalers via dosing roller

    A drum filler is used for micro-dosing dry powder in this SSP2.

  • SSP2 – Cutting process for blister strips in the DPI machine

    The filled blister webs are cut into strips while still in the machine.

  • SSP2 – Winding process for blister strips in the DPI machine

    The blister strips are wound up for further processing later. It goes without saying that the filled blisters are handled with care.

Machine features

Forming blisters

Minimum quantities of active-ingredient powder are dosed into blister cavities for dry powder inhalers. Plastic forming of these tiny cavities is achieved through thermal forming (PE film) or cold forming (aluminum film).

Filling blisters

The powder filling module can be equipped with a drum filler or with a membrane filler. The drum filler produces partially filled cavities whereas membrane filler is filling the blister cavity to 100%.

Closing blisters

Filled blisters are closed with covering or forming film. The sealing tools used can be configured by adjusting pressure, temperature and time separately for each material.

Barrier technology

Compact machine design and detailed knowledge of all processes makes Harro Höfliger a specialist in containment and barrier systems that serve to protect both the operator and the product. For ideal accessibility, ergonomic studies are performed that simulate all processes and operating steps.
