Metallised Films

Unlike Aluminium barrier films (see above) metallised films don't have a continuos layer of aluminium foil, they are only metallised with aluminium. Therefore it is not as steam-tight as aluminium barrier films, but it weighs less, it's more flexible and less susceptible to wrinkles. Metallised films can be sealed with constant heat sealers and impulse sealers.
