They reinforce surfaces and prevent panels from warping when coated with finish foils or veneers on one side. In addition, backing foils are also used as a barrier medium for invisible surfaces in order to reduce the moisture absorption of the wood-based panels. TECOFOIL G is a dimensionally stable continuous foil without a finish surface, which we produce using particularly robust speciality papers. The brown backing foil is used on the reverse side of coated panels and ensures a long-term balance of forces so that no deformation occurs in the first place.
