Requirements in packaging
In packaging, clean, pre-treated surfaces are a prerequisite for printing and sealing. Controlling electrostatic charges also plays a role — particularly on plastic films and web material, whose surface tension is naturally low.
Suitable processes
Which process fits best depends on the part, the contamination and the batch size — we advise on a technology-neutral basis. For this industry, the following are particularly relevant:
- Plasma & corona pre-treatment — corona activation for printing on films and web material
- Electrostatics & ionisation — discharging and cleaning of electrostatically charged surfaces
Test the process at TeSe
Whether a process meets your industry’s requirements on your actual part is shown by a trial: 1–2 hours of testing free of charge. In-depth feasibility studies: CHF 1’200 per day, 50% creditable against a machine purchase.
