Ribbons, stamped pieces, tape and dispenser products

The infusion filter acts as a security filter. The function of the filter consists in retaining particles larger than 20 µm which might be present in the infusion solutions (e.g. aggregated nutrients, pharmaceutical compounds, etc.) or which may originate from the infusion bag and infusion bottle, respectively.


Fabrics can be heat or ultrasonically slit. Ribbons width ranges from 7 mm to 2400 mm (heat-slit) or from 4 mm to 350 mm (US-slit).

Tape & dispenser products

Fabrics can be combined with one or several adhesive layers that enables a cost-efficient and fast joining of the fabric piece to any filter component.

Stamped pieces

Discs or other con-
figurations can be laser
cut, cold or ultrasonically stamped. Disc diameter ranges from 6 to 95 mm.
