50 μm Low Heat Shrinkage PET Film with Excellent Dimensional Stability for FPC & Precision Circuit Printing

Are you experiencing printing misregistration, substrate deformation, or dimensional changes during flexible circuit production?

Our 50 μm low heat shrinkage PET film is designed for FPC-related printing, printed flexible circuits, conductive ink printing, and precision electronic printing where dimensional stability is critical.

With tested heat shrinkage of 0.8% in MD and 0.0% in TD, this dimensionally stable PET film helps minimize unwanted dimensional changes during processes involving heat. Combined with high mechanical strength, good flexibility, and excellent surface wettability, it provides a stable PET substrate for accurate circuit printing and downstream converting.

For FPC and printed circuit manufacturers, material performance directly affects printing accuracy and production consistency. The right low shrinkage PET film for circuit printing can help reduce common processing problems.

In printed flexible circuit manufacturing, even small dimensional changes in the PET substrate may affect circuit alignment, multi-step printing, and die-cutting accuracy.

A low heat shrinkage PET film for FPC printing provides a more stable foundation for precision processing. By minimizing unwanted shrinkage and stretching, the substrate can help support better registration accuracy, more consistent circuit patterns, and improved converting stability.

This is especially important for manufacturers producing fine printed circuits or products that require multiple printing and processing steps.

This 50 μm PET film for precision printing can be evaluated for:

• Printed flexible circuits
• FPC-related printing applications
• Conductive silver ink circuit printing
• Membrane switches and control panels
• Flexible sensors
• Printed electronics
• Precision screen printing
• Electronic insulation and structural layers

For circuit printing manufacturers, substrate stability is not just a material specification—it directly affects production consistency.

Our dimensionally stable PET film for printed flexible circuits combines low heat shrinkage, high tensile strength, good flexibility, and high surface wettability. This combination helps the film maintain better dimensional stability throughout printing, converting, laminating, and die-cutting processes.

The result is a more reliable substrate for manufacturers looking to reduce deformation risks and improve the consistency of precision circuit production.

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