As in blown film, co-extrusion is also a growing process technology, which can provide additional functional, protective, and decorative properties. Blown film is cooled slowly which results in the film being slightly lighter and cloudy, meaning it is not as see-through as cast film. Blown film is also tackier, meaning that is is very sticky and palletised loads can stick to each other. This makes it the ideal solutions for palletised loads that will be stored outside. Its tackiness means the film is very loud when unwinding, but can be made as “low noise” blown film. Because it is “blown” it does not have as great accuracy as cast film.
