56 mN/m Wetting Tension 50 μm PET Film with Low Heat Shrinkage for Conductive Ink Printing

Poor ink wetting, uneven circuit lines, and weak coating adhesion can directly affect the quality and production yield of printed flexible circuits.

Our high surface tension PET film for conductive ink printing features a wetting tension of 56.0 mN/m and excellent tested adhesion performance. With a 50 μm (0.05 mm) thickness, this treated PET film provides a stable substrate for conductive silver ink printing, screen printing, flexible circuits, membrane switches, sensors, and printed electronics.

For manufacturers looking for a PET film with good ink adhesion, this material helps support more consistent printing and downstream processing.

Technical values are typical data and should be verified under the customer's actual ink system and processing conditions.

The surface condition of a PET substrate can directly influence how ink wets, spreads, and bonds to the film. Our 56 mN/m PET film for screen printing is designed to support demanding printing and converting processes.

This high surface energy PET film can be evaluated for applications including:

• Conductive silver ink printing
• Printed flexible circuits
• FPC-related printing applications
• Membrane switches
• Flexible sensors
• Printed electronics
• Functional coating and screen printing

When conductive ink does not wet the PET surface properly, manufacturers may experience broken circuit lines, uneven ink coverage, poor adhesion, or unstable printing quality.

Choosing a high surface tension PET film for conductive ink printing can help improve substrate compatibility and provide a more consistent foundation for precision printing.

Available in rolls, sheets, and custom sizes for different printing and converting requirements.
