ALPINE 11-LAYER TECHNOLOGY
An 11-layer line from Hosokawa Alpine offers enormous flexibility. Regardless of their different viscosities, a wide range of raw materials can be processed in every layer, thus permitting completely new layer structures, e.g. for laminating film. Besides this, the 11-layer line from Hosokawa Alpine offers additional possibilities of optimally balancing out the film layers. Because of this, asymmetric film structures with polyamide for thermoforming applications, for example, can be produced with a significant reduction of the curling effect. Thanks to additional layers of PA, this kind of film is also more elastic and more uniformly formed at the edges after thermoforming. Thicker layers, for example of cheaper raw materials, can be achieved with an 11-layer blow film line in that the same material is processed with two extruders and thus in two layers next to each other. For a number of structures, even higher throughput rates can be achieved when compared with that of a standard 9-layer film.
And last but not least, the higher number of layers of the 11-layer line offers the possibility of realising completely new material combinations which can also mean that the overall layer thickness is reduced and thus a cost saving is achieved, or completely new products are generated which, for example, make later laminating steps unnecessary.
