Our Tent Seam Sealer Tape is made from a single layer of PU material, with one side coated in hot-melt adhesive. This design ensures excellent adhesion and waterproofing. During use, specialized heat-sealing equipment applies heat and pressure, causing the adhesive to melt, fill gaps, and solidify upon cooling to create a strong, sealed bond. Thanks to its superior performance, the tape is widely used on the seams of PVC/PU-coated fabrics, including raincoats, tents, outdoor jackets, fishing umbrellas, cold-weather clothing, waterproof bags, car covers, multifunctional outdoor wear, and duty uniforms. Its strong adhesion and waterproof properties help these products maintain excellent performance and long-lasting durability in harsh weather and challenging environments.
