Embodiment Construction
[0017] According to the present invention, a single-layer or multi-layer tubular food film that can be smoked, air-dried, and peeled, especially fully automatic, is proposed, especially one that is suitable for smokeable and / or air-dried sausage or meat. Casings for products, this polymer-based food film is supplied via a (co)extrusion film blowing device using (co)extruded plastics supplied to nozzles on The homogeneous molten plastic is made of polystyrene (polystyrene, abbreviated as PS) or a mixture of various PS and a plastic mixture composed of PVOH and / or PEBA.
[0018] Advantageously, not only is it possible for the first time to spray through the nozzle, and then use the bidirectional stretching of the three-bubble method to realize the large-scale production of tubular food films that can be smoked, air-dried, and peeled, especially fully automatic peeling, and It is also possible to completely dispense with the use of nets, soft carrier materials or fluff, which are...
