Abstract: A film of plastic material for wrapping, obtained by cast co-extrusion in three layers, wherein an inner layer consists of elastomer-based propylene, containing ethylene, and metallocene polyethylene, while a central layer and an outer layer consist of metallocene polyethylene with different melt flow indexes, that of the metallocene polyethylene of the central layer being the lower one.
