High-precision carrier tapes and functional materials for global electronics.
Decoding the complexity of modern semiconductor and component protection.
The "Co-Packaging" (Contract Packaging) industry has evolved from simple boxing to high-tech component protection. In the global industrial chain, specialized Wholesale Co Packaging Factories play a pivotal role. As semiconductor devices shrink (7nm, 5nm, and below), the demand for Carrier Tapes and Cover Tapes with 100% ESD reliability has surged. Market data suggests the global electronic packaging material market will reach billions by 2030, driven by the rapid expansion of 5G and AI infrastructure.
Future-ready factories are shifting toward Eco-friendly & High-Precision solutions. Trends include the development of halogen-free materials, biodegradable tapes, and tapes designed for ultra-high-speed SMT (Surface Mount Technology) lines. Automation is no longer optional; it is the standard for maintaining the strict tolerances required by automotive and medical electronics.
Modern enterprises are seeking more than just a supplier; they need a strategic partner. Procurement focus has shifted from "lowest cost" to "total cost of ownership," emphasizing consistent peel force, thermal stability, and long-term shelf life. International buyers from Europe, North America, and SE Asia are increasingly vetting factories based on ISO certifications and ESG compliance.
Established in June 2007, Jiangsu Yongjia has dedicated 18 years to the deep cultivation of electronic packaging materials. As a comprehensive service provider, we operate from a 16,000 square meter facility in Nantong, optimized for high-capacity production and cutting-edge R&D.
Our focus remains on the core track of functional tapes: heat-seal cover tapes, self-adhesive cover tapes, acetate cloth tapes, and PET tapes, serving as a cornerstone for the global electronic component supply chain.

Combining cost-efficiency with world-class engineering and supply chain resilience.
Our in-house laboratories specialize in polymer chemistry, ensuring that every roll of cover tape meets exact peel-strength requirements. We simulate extreme environmental conditions to guarantee performance in various global climates.
Located in the heart of China’s industrial hub, we have immediate access to raw materials and international shipping ports, reducing lead times for our global wholesale partners.
With ISO and UL certifications, our production lines follow rigorous quality protocols. We provide full traceability for every batch, a critical requirement for automotive and aerospace clients.
Empowering diverse sectors with specialized packaging technology.
The core of Co Packaging Factory operations lies in the material science of Cover Tapes. A cover tape must possess a delicate balance: it must adhere securely to the carrier tape to prevent component loss, yet peel away with consistent force during high-speed SMT assembly. Our Heat Seal Cover Tapes are engineered with multi-layer co-extrusion technology, ensuring that the adhesive layer does not migrate or leave residue on the carrier tape pockets.
For sensitive MOS transistors and integrated circuits, our Self-Adhesive Cover Tapes offer an alternative that eliminates the need for heat during the sealing process, thus protecting temperature-sensitive components. The electrical protection series, specifically our PET Tapes, provides high dielectric strength, making them indispensable for modern power electronics and lithium-ion battery insulation.
In the realm of Acetate Cloth Tapes, we offer both release liner and non-liner versions. These are particularly favored in the "White Goods" and automotive industries due to their excellent conformability and high temperature resistance. By integrating flame-retardant properties, we help our clients meet stringent UL safety standards, ensuring that the end-user products are safe for global markets.
As a leading Wholesale Co Packaging Factory, Jiangsu Yongjia continues to invest in "Industry 4.0" upgrades. Our manufacturing floors are equipped with automated tension control systems and vision inspection modules that detect defects in real-time. This level of precision is what separates a standard factory from a global industry leader.
Jiangsu Yongjia recently upgraded its clean-room production lines to meet the 2025 semiconductor packaging standards, focusing on low-particle-count materials.
