High-precision functional tapes engineered for the semiconductor and electronics supply chain.
The global market for Optically Clear Adhesive (OCA) and high-functional electronic tapes has seen unprecedented growth. As the "invisible bridge" in modern electronics, these materials are critical for bonding touch screens, display panels, and semiconductor packaging. Currently, the industry is transitioning toward ultra-thin, high-transparency, and heat-resistant solutions to support the next generation of smart devices.
Integration is the future. We are seeing a massive shift toward Mini-LED and OLED technologies, which require adhesives with superior UV resistance and stress buffering. Furthermore, the rise of foldable devices and 5G infrastructure demands tapes that maintain structural integrity under extreme temperature fluctuations and repetitive mechanical stress.
International Tier-1 manufacturers are increasingly seeking Wholesale Optically Clear Adhesive Suppliers who can offer vertical integration. The demand is no longer just for a product, but for a stable supply chain that guarantees ISO-certified quality, environmental compliance (RoHS/REACH), and rapid R&D iteration to match fast-paced electronic product cycles.
Established in June 2007, Jiangsu Yongjia has spent 18 years perfecting the art of electronic material manufacturing. As a premier provider of functional tapes, we operate out of a state-of-the-art 16,000 m² facility in Nantong. Our expertise spans from initial R&D in our advanced laboratories to large-scale production of Acetate Cloth Tapes, PET Tapes, and Heat-Seal Cover Tapes.
Our commitment to excellence is backed by rigorous quality control systems and a deep understanding of the semiconductor packaging landscape, making us a trusted partner for global enterprises looking for high-reliability adhesive components.

Our products are engineered to solve specific engineering challenges across diverse sectors.
Used in high-temperature environments for wire harness protection and dashboard display bonding, ensuring long-term durability in fluctuating climates.
Critical in SMT (Surface Mount Technology) processes. Our cover tapes provide reliable carrier protection for chips during high-speed transport and picking.
Flame-retardant acetate tapes are the industry standard for insulating motors, transformers, and complex electrical circuits in heavy-duty machinery.
We control the entire process from raw material sourcing to coating, slitting, and final inspection. This ensures cost-efficiency and superior quality control compared to trading companies.
Every industrial project is unique. We provide tailored widths, lengths, and adhesive strengths (low-tack to permanent) to meet specific assembly line requirements.
Our facility holds full ISO certifications, and our products undergo rigorous testing for flame retardancy and electrical insulation, ensuring compliance with global safety standards.
The company focuses on the core track of functional tapes for the electronic industry, primarily engaged in the R&D, manufacturing, sales, and after-sales service of a series of products, including heat-seal cover tapes, self-adhesive cover tapes, acetate cloth tapes, glass fiber tapes, and PET tapes.
As a leading Wholesale Optically Clear Adhesive Supplier, we understand that "Optical Clarity" is just the tip of the iceberg. True expertise in this field involves managing the complex relationship between refractive indices, dielectric constants, and adhesion energy. For instance, in modern touch-panel assembly, the adhesive must not only be 99%+ transparent but also have the ability to fill the gaps between ITO (Indium Tin Oxide) sensors without trapping air bubbles or causing yellowing over time.
Our PET and Acetate series products, while specialized for insulation and packaging, share the same high-precision manufacturing DNA. Whether it's the Flame-Retardant Acetate Cloth Tape used in transformer windings or the PET Electrical Protection Tape used in Li-ion batteries, every roll is produced under clean-room conditions to prevent contamination, which is the number one enemy of high-performance adhesive systems.
For global procurement managers, sourcing from a factory like Jiangsu Yongjia means you are accessing 18 years of technical data. We help our clients mitigate risks such as adhesive migration, delamination under heat, and chemical incompatibility with electronic components. Our latest news confirms that we are continuously strengthening the foundation for the cover tape industry, helping the domestic substitution process in semiconductor packaging through technological breakthroughs.
