Multi-Layer Barrier Films
Building on Sigma's technologies for depositing functional nanolayers in vacuum, Sigma barrier films benefit from various multi-layer architectures that include a) polymer nanolayers applied before, after, or before and after deposition of the active barrier layer, and b) the applications of nanoparticle sealing layers creating both a torturous path for moisture, as well as a trap for moisture that enters the multi-layer structure. The result is vastly superior barrier properties, better durability, and enhanced printability.
One Layer Is Better Than None - MonoLayer Barrier Films
Application of a single, protective, coating onto any inorganic barrier layer, using SigMaterials VaporPhase deposition technology, results in drastically improved barrier properties. Sigma MonoLayer barrier films consist of a single metallized layer followed by a functional protective layer for increased barrier performance ideal for most food and electronics packaging applications.
More Layers Are Better Than Few - Multi-Layer Barrier Films
Sigma MultiLayer barrier films consist of a multitude of inorganic and organic layers to produce truly groundbreaking barrier performance for industrial applications such as flexible displays and photovoltaics.
