For films, in several series of experiments concerning various thicknesses of various polymers, permeability coefficients have been calculated for a reference thickness of 40 pm. Units differ for the various gases but are comparable for the different polymers tested with the same gas. The following data (without units) are only given to provide an idea and cannot be used for designing any parts or goods. [Pg.297]

EVOH has a low permeability to oxygen, evaluated at 0.35 up to 1.8 versus a full range of 0.35 up to 11000 for all tested plastics. [Pg.297]
