Aluminium foil is typically less than 150 µm in thickness.Foils are available in gauges as low as 6.3 µm.Heavier foil gauges (> 17 µm) provide an absolute barrier to gases and liquids.A typical water vapour transmission rate (WVTR) for 9 µm foil is 0.3 g/m 2 per 24. hours at 38 °C and 90% RH.. As thickness is reduced, foil becomes more vulnerable to tearing or pinholing.
