NanoPaper™ Flexible Electronics Substrate — 5 x A4 Sheets

Tangho NanoPaper™ is a bio-based cellulose nanofiber film substrate engineered for printed and flexible electronics prototyping, evaluation, and research. It provides a smooth, electronics-ready surface, strong handling performance, and validated thermal tolerance for common cure profiles in a standard A4 format that fits benchtop printers, ovens, and lab workflows. NanoPaper is suitable for work on printed sensors, antennas, RFID/NFC structures, heaters, interconnects, and related flexible electronic devices.

Thickness options

• 50 µm — Recommended
• 30 µm

Which thickness should I start with?

For most first-time evaluations, we recommend 50 µm. It offers the best all-around balance of robustness, handling, and process compatibility for general printed-electronics development. The 30 µm option remains available for thinner constructions where lower caliper is a specific requirement.

For first trials, use the lowest curing temperature and shortest dwell that achieve the required result. Pre-dry when moisture pickup is suspected, support sheets flat during elevated-temperature curing, and allow ambient reconditioning after higher-temperature annealing before final flexibility assessment.
