Ribbons, stamped pieces, tape and dispenser products

Sefar has developed state-of-the-art manufacturing facilities to produce custom components to fit the most demanding requirements. All healthcare products are processed in our Class ISO 7 clean room.

Fabricated products

Tape & dispenser products

Fabrics can be combined with an adhesive layer which enables a cost-efficient and fast joining of the fabric piece to the test strip.
In addition the fabric can be welded together with a paper / membrane layer, eliminating subsequent joining processes.


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

Stamped pieces

Sefar fabrics can be provided pre-cut in virtually any configuration by laser cutting, cold stamping or ultrasonic stamping.
