Printed PET film needs enough energy and airflow to release solvent or water while the web remains within temperature, tension and dimensional limits. Infrared dryer design should therefore follow the ink system and web behaviour, not only the installed lamp power.
Record PET gauge, width, colour, printing method, ink chemistry, coating weight, initial temperature, target dryness and maximum web temperature. Confirm whether migration, odour or residual-solvent requirements apply.
Residence time changes with press speed. Divide the dryer into controllable zones and use speed-related power limits so the web receives an appropriate energy dose during acceleration and deceleration.
Measure the web where heating is most severe and confirm that thermal expansion does not disturb registration, curl or winding.
| Input | Why it matters | Record |
|---|---|---|
| Web | Defines thermal and handling limits | Gauge, width and tension |
| Ink | Controls evaporation and cure needs | Chemistry and coat weight |
| Dryer | Delivers and removes energy | Zones, airflow and speed logic |
Direct airflow across the printed surface without fluttering the film. Balance exhaust and make-up air for vapour removal, while considering the ink supplier's ventilation and safety requirements.
Connect lamp power to web motion and define a rapid stop response. Validate dryness, blocking, adhesion, odour, registration and roll quality across the full production speed range.
Coordinate the emitter with YFR industrial infrared heating lamps and heating modules and controls. Confirm the final configuration with product trials and documented acceptance limits.
No. Film temperature and dimensional stability require separate limits.
No. Excess surface temperature can distort the web or damage the ink film.
It removes released vapour and helps maintain the intended drying rate.
Reduce radiant power quickly and follow the approved web-protection sequence.
Send YFR your material, dimensions, target temperature, cycle time and current equipment details for an application-specific review.
