Madeira Heat Seal Embroidery Stabiliser – Perfect for Iron-On Badges & Appliqué (20cm x 50m)

A premium permanent adhesive embroidery stabiliser film designed for iron-on badges, patches and appliqué applications.

Madeira Heat Seal is a professional-grade adhesive embroidery stabiliser developed for securely fixing badges, patches, appliqués and decorative elements to fabric. Once heat activated, it forms a permanent bond that remains stable through wear and washing, making it ideal for applications where reliability and longevity are essential.

Manufactured from 100% polyamide, Heat Seal is supplied as a smooth adhesive film on a 20cm x 50m roll, allowing precise cutting and controlled application. It is activated using a household iron or heat press and is washable up to 40°C, making it suitable for garments, uniforms and frequently worn items.

Heat Seal is especially useful when preparing appliqué or badges prior to embroidery or stitching, as it prevents shifting, puckering and movement during sewing. It provides a clean, invisible bond without adding unnecessary bulk, ensuring a professional finish on a wide range of fabrics including knits, denim, canvas and woven textiles.
