Metallised Cellulose Acetate is a Cellulose Acetate film with one side metallised with Aluminium. They have a reflective silvery surface that is highly flammable. It is a lightweight and cost-effective way to achieve a metallic look. Metallisation is performed using a physical vapour deposition process. The metal is heated and evaporated under vacuum and then it condenses on the cold polymer film. Other metals such as nikel or chromium may also be used to coat films. The coating is much thinner than a metal foil could ever be. The thickness of the metal is measured and described in the material’s specific electrical resistance in ohms per square. The coating will not fade or discolour over time. The coating also reduces the permeability of the film to light, water and oxygen. The properties of the film remain, such as higher toughness, the ability to be heat sealed, and a lower density at a lower cost than an aluminium foil. However metallised cellulose acetate still cannot match the barrier properties of foil.
