Electronic Leakage Tester applies to test the hermetic sealing quality and performance of packaging bags, bottles, cans and so on, used in industries of food, beverage, pharmaceuticals, personal care and so on          

Oxygen transmission rate (OTR) is the measurement of the amount of oxygen gas that passes through a substance over a given period. It is mostly carried out on non-porous materials, where the mode of transport is diffusion, but there are a growing number of applications where the transmission rate also depends on flow through apertures of some description.

Water vapor permeability analyzer is used to test water vapor transmission rate (WVTR) of films or sheets materials for flexible packaging.
