Converting Quality
Consistency that carries into your next process.
ATR-PI-EP combines improved dimensional stability, higher modulus, mechanical uniformity, thickness uniformity and flatness to support registration and converting control.
01Dimensional Stability+
Improved dimensional behavior supports registration, layer alignment and repeatable converting in demanding processes.
02Mechanical Uniformity+
Higher modulus and more uniform mechanical performance support controlled web handling through coating, lamination and precision converting.
03Thickness & Flatness+
Improved thickness uniformity and flatness help maintain consistent contact, alignment and downstream process control.
Available Forms
Supplied in the form your process requires.
ATR-PI-EP is available in master rolls, slit rolls and die-cut parts. Width, length, core size, winding and converted format are confirmed for the intended process.
