As a leading Wholesale Thermal Sealing Tape Manufacturer & Factory, Jiangsu Yongjia Electronic Materials Co., Ltd. has witnessed the rapid evolution of the global electronic materials market. Today, thermal sealing tape (commonly referred to as heat seal cover tape) is the backbone of the Surface Mount Technology (SMT) industry. It serves as the critical protective barrier for electronic components—ranging from tiny resistors to complex integrated circuits—as they are transported from the manufacturing plant to assembly lines across the globe.
The rise of 5G, AI, and Electric Vehicles (EVs) has pushed the demand for miniaturized components to an all-time high. Thermal sealing tapes must now offer extreme peel-force consistency and anti-static properties to prevent component loss and electrostatic discharge damage.
We are seeing a shift toward Eco-friendly & Halogen-free materials. Modern factories require tapes that can withstand high-speed packaging machines (over 10,000 components per hour) without failing, ensuring zero-defect production cycles.
With 18 years of technical expertise, our R&D lab focuses on polymer chemistry to ensure that our heat-seal adhesives provide a stable bond across diverse temperature ranges, establishing us as a reliable authority in Nantong's industrial hub.
Established in June 2007, Jiangsu Yongjia has dedicated eighteen years to deep cultivation in the functional tape industry. Located in Nantong, our facility spans 16,000 square meters with a 9,000 square meter state-of-the-art production workshop.
We are not just a manufacturer; we are a comprehensive service provider. Our operations integrate R&D, manufacturing, and global sales. We specialize in functional tapes including heat-seal cover tapes, self-adhesive cover tapes, acetate cloth tapes, and PET tapes.
Our flagship Standard High Temperature Series is engineered for high-precision SMT packaging. Designed with advanced thermal-sensitive adhesives, these tapes ensure a secure seal on various carrier tape materials (PS, PC, PET) while maintaining a stable peel force. This prevents "pop-out" during automated assembly, significantly reducing downtime for global procurement partners.
Available in both Flame-Retardant and standard versions, with or without release liners. These are essential for wire harness wrapping and transformer insulation in the electrical appliance industry.
Engineered for high-tensile strength and electrical protection. Our Glass Fiber Tapes are the preferred choice for heavy-duty bundling and high-temperature insulation scenarios in automotive stamping and motor manufacturing.
Perfect for heat-sensitive components. Our Self-Adhesive Cover Tapes provide a reliable seal without the need for thermal activation, meeting the diverse packaging needs of modern semiconductor back-end processes.
Global procurement teams from Europe, North America, and Southeast Asia look for three things: Consistency, Cost-efficiency, and Customization. Jiangsu Yongjia excels in all three by providing localized solutions for the following high-growth sectors:
Our Nantong facility utilizes automated coating lines and precision slitting machines. This ensures every roll of Wholesale Thermal Sealing Tape meets tight tolerance specifications required by high-speed SMT feeders.
We understand that one size doesn't fit all. Whether you need a specific peel force (e.g., 30g to 70g) or customized tape widths (5.3mm, 9.3mm, 13.3mm etc.), our in-house lab can formulate adhesives to meet your exact carrier tape material specs.
Being based in Nantong gives us a logistics edge. We offer rapid lead times and consolidated shipping, helping global distributors reduce inventory costs and maintain a lean supply chain.
