PETREL Security Sewing Threads are used for sewing passports and other Security booklets and are an extremely important element in their security.
Due to their usage, these threads are designed to be very mechanically resistant and are dyed in mass, which gives them excellent light resistance. Compared to Polyester/Cotton or 100% Cotton threads, Petrel threads offer an essential advantage on these two points.
Petrel offers 3 types of threads depending on the characteristics of the documents and multiple color choices both in the visible spectrum and under Ultra-Violet light.
Petrel’s expertise in this area has long been recognized, and many passports are sewn with PETREL threads.
Created in 1985, PETREL is the French leader in the supply of security products for securing documents. Located in France, near Paris, PETREL manufactures and develops 3 main product lines: Security inks, security fibers and security sewing threads.
