With the availability of thinner grades of Glassflake, produced by the spun method of manufacture, a greater number of glass flake layers are formed within the film, increasing the length of the tortuous path. With this the rate of permeation can be reduced further, often by an order of magnitude, if not greater, while also requiring a lower loading level of Glassflake.
The use of thinner flake also allows the retention of a high aspect ratio flake, even when there is a requirement to significantly reduce the particle diameter, for example with a thin film coating.
