Polyethylene films for the electronics industry
Antistatic and cleanroom-made films that protect semiconductors, printed circuit boards and sensors from electrostatic discharge and contamination.
What the electronics industry expects from packaging
Four risks the packaging material has to handle — and our answer to each.
ESD damage
Electrostatic discharge above 100 V can already damage sensitive components — conventional PE film can build up a surface charge of up to 10,000 V.
Contamination
Dust and fibre particles can cause failures in microelectronics and semiconductor manufacturing.
Marking and handling
ESD-sensitive products must be clearly marked on the packaging so that every handling step is correct.
Compliance
The electronics industry places strict requirements on packaging materials.
How ESD and cleanroom film is made
Four steps — antistatic performance throughout the entire film thickness.
- 1
Formulation
LDPE/LLDPE with antistatic additive; the additive ratio is set to the required surface resistance.
- 2
Extrusion
3-layer co-extrusion with the additive evenly distributed through the full thickness; for cleanroom film inside the ISO Class 9-compatible cleanroom.
- 3
Printing
ESD warning symbols, handling instructions and company information in flexo print, up to 6 colours.
- 4
Converting
Flat film, tubing, bags or sacks — cut and sealed to the size you need.
Where does ISO Class 9 sit on the cleanliness scale?
ISO 14644-1: permitted particles (≥0.5 µm) per cubic metre, by class.
Our cleanroom is not certified: it operates and is measured to ISO 14644-1 Class 9 — the measured value is a fraction of the Class 9 limit.
Our solutions for the electronics industry
Cleanroom film
Film made in an ISO 14644-1 Class 9-compatible cleanroom with minimal particle count — for semiconductor, medical and optical applications.
Details
ESD (antistatic) film
Antistatic additives matched to the application, 30–200 µm, 3-layer co-extrusion. Typically pink or transparent; as flat film, tubing, bags and sacks.
Details
ESD-marked printing
We flexo-print ESD warning symbols, handling instructions and company information on the film, in up to 6 colours.
