Beschreibung
Zusammenfassung:Plant (200) for blowing extrusion, or cast extrusion, of a multilayer film, comprising an extrusion head (2) provided with one or more inlets for feeding of respective polymers in the molten state, at least one of said polymers being a low-melting polymer (with melting point generally less than 60°C) or highly amorphous polymer, and/or with MFI > 6 g/ 10 min, said plant comprising a system of melting (100) of said low-melting or highly amorphous polymer and/or with MFI > 6 g/10 min with tank melter (101) which is in fluid communication with at least one of said inlets of said extrusion head (2), said melting system (100) being in place of at least one single-screw extruder (1) feeding said extrusion head (2).
