We Invented Capsealing

Lepel developed the first induction sealer and application back in the late 1960s. A company packaging photo chemicals, FRP Chemical in NJ, thought they had solved a leakage problem caused by glass breakage. Their first solution was to change to a plastic bottle and cap. They later found out that the plastic caps stress-relieved over time and loosened during shipment. The leakage problem returned. FRP Chemical’s Packaging Engineer, Jack Palmer, along with 3M and Lepel, created the process of induction sealing, the “Lepel Seal” as it was originally called.
