Work has shown that (1) the permeability of saran film increases exponentially with increasing temperature due to activation energy, (2) permeability of saran film decreases slightly with increasing pressure–but to only a very slight extent, (3) microwave radiation does not affect permeability as long as the film is not heated during treatment, and (4) low amounts of liquid additives correlate with lower permeability. It is suggested that the barrier property of saran film can be improved without sacrificing the processing ability.
