Cleanroom

Contamination-free films for the pharmaceutical, electronics and food industries

Cleanroom

Controlled production environment

Our cleanroom operates in accordance with ISO 14644-1 Class 9. Measured particle counts are approximately 400,000 particles (≥0.5 µm) and 70,000 particles (≥5 µm) per cubic metre – well below the Class 9 limit (35,200,000/m³) and significantly cleaner than a conventional industrial environment. The system supplies an average of 1,000 m³/h of filtered air while keeping the temperature at around 23°C. Air filtration and positive pressure continuously prevent external contaminants from entering. This environment is ideal for polyethylene film extrusion and for bag and pouch converting, where hygiene and surface quality are critical.

Benefits of the cleanroom in film production

1
Controlled particle level: The hygiene protocol and air filtration prevent external contamination from entering the production process.
2
ISO Class 9 compliance: Our cleanroom operates in accordance with ISO 14644-1 Class 9, providing an environment that meets international requirements.
3
Serving critical industries: An ideal solution for manufacturing packaging materials for the medical, pharmaceutical, electronics and food industries.
4
Reduced risk: The strictly controlled production environment reduces the likelihood of product defects and quality complaints.

Operational and design features

This is how we ensure contamination-free production

Design and construction

The cleanroom was designed so that its materials and construction minimise particle adhesion. Smooth surfaces and an easy-to-clean design make regular maintenance simple.

Particle control

The concentration of airborne particles is monitored continuously. Measured values: approx. 400,000 particles (≥0.5 µm) and 70,000 particles (≥5 µm) per cubic metre. This corresponds to ISO Class 9.

Air filtration and air exchange

Our air-exchange system provides a continuous supply of filtered air. The controlled air exchange maintains the specified cleanliness level and a stable temperature of around 23°C.

Personnel protocol

The cleanroom may only be entered in dedicated protective clothing. Strict rules govern our internal hygiene and cleaning protocol.

Airlock entry

The airlock entry system prevents external contaminants from entering and separates the cleanroom air space from the rest of the plant.

Positive pressure

The positive pressure maintained in the cleanroom ensures that, in the event of any leak, clean air flows outward, preventing contamination from entering.
