Our Firm

In 1979, Daniel VERRON, a reputed and insasiable inventor of medical devices, founded LEF / LABO ELECTROFRANCE, in order to design solutions to evolving sterilization methods. He designed then the first French rotary heat sealer. In 2003, after sharing his expertise and experience during 8 years, he passed down the general management to his daughter Delphine VERRON. While preserving this legacy, her goal is now to conceive ranges of innovative rotary sealing machines that combine : robustness, simplicity and advanced technologies. Today, LEF is supported by a fast developing partner and distributor network and continues its international growth.
