Heat Seal

Secure your custom patches with ease using our Heat Seal Backing for Embroidery Patches—the industry-standard solution for applying patches to garments with a heat press or household iron. This backing provides a strong, durable bond that adheres cleanly to most fabrics including cotton, polyester, and blends, making it ideal for uniforms, hats, jackets, bags, and more.

Our heat seal film is engineered to withstand repeated washing and daily wear, offering long-lasting adhesion without compromising the flexibility of the fabric. It creates a smooth surface that won’t lift or bubble, ensuring a professional-grade finish for embroidered or woven patches. Perfect for patch makers, apparel decorators, and DIY enthusiasts looking to streamline patch application and offer retail-ready products.
