The barrier layer reduces the oxygen transmission rate and protects the product and the anti-fog additive of the lidding film changes the surface properties so that moisture inside the package does not form droplets but spreads out on the surface of the film, added KWH Plast.
The film properties are verified in a laboratory in order to find and quantify the optimal mechanical, optical and sealing properties required before final tests on production lines at the packaging converter.
