Did you know? In can making, M.E. (Metal Exposure) and High M.A.'s (Milliamp) both mean the same thing: exposed metal inside a can.
During quality control, plants perform a metal exposure test; they fill cans with a saline solution and measure current in milliamps. The higher the reading, the more porous or damaged the internal coating; and the more metal is exposed and at risk of corrosion
If coatings fail the test, production is stopped to fix the issue; avoiding serious product loss and corrosion risks
So whether your plant says “We’ve got M.E.s!” or “We’re seeing high M.A.s!”; both flag the same issue: exposed metal that could corrode.
Knowing both terms helps operators act fast and protect can quality. What does your plant say? #CanMaking #MetalPackaging #QualityControl #CoatingIntegrity #CanPlantOperations
