Known as the "Gold Film" of the plastics world, Polyimide (PI) film represents the pinnacle of polymer material science. Globally, the demand for wholesale Polyimide film has surged, driven by the rapid miniaturization of electronic devices and the transition towards high-frequency, high-speed telecommunications. From aerospace insulation to the flexible printed circuits (FPC) in your smartphone, PI film provides unparalleled thermal stability (maintaining properties from -269°C to +400°C), excellent dielectric strength, and chemical resistance.
Today, the global market is shifting toward specialized variants. Suppliers are no longer just providing standard films; they are developing low-dielectric (low-Dk/Df) PI for 5G, transparent PI for foldable displays, and black PI for light-shielding applications in automotive sensors.
As AI chips generate more heat, the need for high-thermal-conductivity PI films and heat-resistant cover tapes is critical for semiconductor reliability.
Electric vehicle (EV) batteries require high-voltage insulation materials. Polyimide films and PET tapes are becoming standard for battery pack protection.
Factories are moving towards automated SMT lines, requiring high-precision heat-seal and self-adhesive cover tapes for component delivery.
Registered in June 2007, Jiangsu Yongjia has spent over 18 years mastering the science of functional electronic tapes and films. We operate from a state-of-the-art 16,000 m² facility in Nantong, blending traditional manufacturing excellence with modern R&D.
Why do global enterprises choose us as their Polyimide film supplier? It’s because we understand the "Cost of Failure." In electronics, a tape that loses adhesion at high temperatures can cause millions in damage. Jiangsu Yongjia focuses on the core track of functional tapes, providing:
Our materials are the silent heroes inside the world's most advanced technology, ensuring safety, insulation, and connectivity.
Used in wire harness wrapping and battery insulation, where heat resistance is non-negotiable for passenger safety.
Crucial for chip carrier tapes and protection during the stamping and etching processes in wafer fabrication.
Flame-retardant acetate cloth tapes protect internal circuitry in consumer electronics and home appliances.
Providing temporary carrier and surface protection for metal-stamped components in complex assemblies.
Being located in Nantong’s industrial hub allows us to source raw polyimide resins and specialized chemicals efficiently, ensuring stable lead times for global orders.
Unlike generic wholesalers, we are a Polyimide film factory. We can adjust tape thickness, adhesive strength, and anti-static levels (ESD) to match your specific machinery.
Our 18-year legacy is built on trust. Every batch undergoes rigorous testing for thermal aging, tensile strength, and dielectric breakdown.

2025-12-10The global procurement landscape for wholesale Polyimide film and related tapes has changed. Procurement officers today prioritize "Total Cost of Ownership" rather than just the unit price. This includes reliability, consistent peel strength for automated lines, and compliance with environmental regulations like RoHS and REACH.
In North America and Europe, there is a strong demand for high-performance PI films used in aerospace and medical electronics. In the Southeast Asian market, the focus is on cost-effective, high-volume cover tapes for the massive consumer electronics assembly industry. Jiangsu Yongjia serves these diverse needs by offering a tiered product range—from standard high-temperature series to enhanced performance variants.
Our PI films and tapes are tested for:
As we move toward 2030, the "Smart Factory" concept will require tapes with integrated RFID or high-contrast printing for traceability. Jiangsu Yongjia is already investing in these R&D paths, ensuring that our partners are always ahead of the technological curve. We don't just sell tape; we provide the material foundation for the next generation of electronic devices.
