For more than 45 years SEF is serving the heat transfer industry with Die Cut, screen printing, HF welding and Flock & Flex now. From the early screen printing products we made in the 70’s, our first « digital cutting » films 30 years ago, to the latest PU flex, we came a long way working with heat transfer materials.
In the factory we formulate our own PU, we coat our own films… Manufacturing, R&D, QC, shipping, all in one place.
