Film extrusion has seen tremendous development of the last 40 years, and most significantly over the last 15-20 years. Machine builders are capable of producing 13 layer films in a single pass on blown film machines that heretofore required multi-step lamination processes to produce. The resultant films do not only improve productivity by reducing the number of manufacturing steps required, but also produce films with improved properties and reduced cost. This paper will investigate various higher order films, their design, properties, applications, and limitations, as well as make a brief insight into the future of this technology.
