How it works

Induction seal inspection, reinvented

Induction sealing bonds a foil liner to the container rim with heat — but a fold, an air gap, or an overheated zone is invisible to the naked eye. TheSealCheck™ reads the heat signature of every seal as it forms, so a flawed bond is flagged before it ever leaves the line.

100% non-destructive testing
