Here at Techbelt we specialise in the design and manufacture of small rotary heat sealing bands that can be custom made to fit any band sealer on the market. We produce all our belts in house at our facility in the UK and ship to our customer both in the UK and overseas. There are two main materials we use which are Tefsil 3 and Tefsil 3 bronze. The bronze material is high performance material that offers extended life. Tefsil 3 is brown in colour and most common which is an excellent cost effective product to be used as a rotary heat sealing band.
