The BOBST DarkNight process produces high barrier metallized films through defect reduction and web-handling optimization.
Loss of barrier performance due to defects is a common problem
Defects on metallized films lead to a drastic deterioration of barrier properties and poor visuals known in the industry as “Starry Night”. Reduced water vapour and oxygen barrier in turn translate in to a reduction in shelf life of food products.
