In the current global electronics landscape, the demand for Heat Sealing Strips (Cover Tapes) has reached unprecedented heights. As semiconductor devices shrink and the complexity of Surface Mount Technology (SMT) increases, the role of protective packaging becomes critical. Heat sealing strips are not just simple tapes; they are sophisticated functional materials engineered to protect sensitive components from electrostatic discharge (ESD), physical impact, and environmental contamination during high-speed automated assembly.
With the rapid expansion of 5G infrastructure, Electric Vehicles (EVs), and AI-driven hardware, the global market for high-performance sealing strips is projected to grow significantly. Large-scale procurement centers in North America, Europe, and Southeast Asia are increasingly looking for suppliers that can provide consistent peel force, thermal stability, and long-term reliability. As a Wholesale Heat Sealing Strip Supplier, we address these global needs by providing materials that comply with EIA-481 standards, ensuring seamless compatibility with all major carrier tape systems.
Established in June 2007, Jiangsu Yongjia Electronic Materials Co., Ltd. has spent over eighteen years mastering the art and science of functional tapes. Located in the industrial hub of Nantong, our 16,000-square-meter facility is a testament to Chinese manufacturing prowess and technological innovation.
Our commitment to "People-Oriented" development and rigorous R&D has positioned us as a comprehensive service provider with significant influence in the electronic materials industry. We don't just manufacture; we engineer solutions that secure the future of electronics.
The transition to sub-7nm chips makes components extremely sensitive to static. Modern heat sealing strips must provide consistent surface resistivity to prevent ESD failures during the "de-taping" process.
As reflow soldering temperatures increase, cover tapes must maintain structural integrity. Our enhanced high-temperature series ensures that the seal remains airtight even under extreme thermal stress.
Global procurement standards now prioritize RoHS and REACH compliance. We focus on halogen-free and recyclable materials to meet the green manufacturing requirements of international tech giants.
Our products are integrated into the world's most demanding supply chains, providing localized solutions for diverse industries.
Unlike standard trading companies, we are a direct factory. Our R&D laboratories allow us to customize Heat Sealing Strips based on specific peel force requirements (ranging from 10g to 130g) and carrier tape materials (PS, PC, or PET).
With 16,000 sqm of production space, we can handle high-volume wholesale orders without compromising on lead times. Our automated coating lines ensure uniform thickness and adhesive distribution across every roll.
Located near Nantong and Shanghai ports, we offer efficient international shipping. We understand the documentation needs of global buyers, ensuring a smooth customs process for your supply chain.
Our ISO-certified facility maintains rigorous quality checks at every stage—from raw material sourcing to final tensile strength and aging tests. Reliability is our core promise.
Capacity optimization and technological advancement are becoming core competencies in the global market.
