What Is A Hermetic Heat Sealer?

Alex Todd

A hermetic heat sealer refers to the quality of seal (or weld) that is achieved by the heat sealer device.

Hermetic is an air-proof (or complete) seal that does not allow gas ingress from the likes of air or oxygen to pass through.


Hermetically sealed packaging can extend product shelf life and offers enhanced protection for the products inside as they are less exposed to moisture damage and other contaminants that lead to deterioration.
