Film coating the surface of aluminum profiles is a technology that is applied by the upper layer of other material on background material, either dry film coating, film coating with wax or hot-film coating to improve or appropriate to change the basic properties of carriers. To ensure good coherence of both materials is used glue (for most applications). The thickness of this layer is the hundredth of a millimeter (about 5 g of glue per 1 m2).
By film coating the classical materials are put in layers (textiles, paper, plastic, aluminum), and synthetic materials, too.
