Extrusion & Co-extrusion
We have the possibility of making films or sheaths: PEHD-PEHD, HDPE-PEBD, PEHD-PEBD, PEHD-Metallocene, PEBD-Metallocene, PE-EVOH-PE, PA-PE, PA-EVOH-PA, PP-PP, ...
CO-EXTRUSION: a process that allows the production of a multilayer complex without having to laminate. Several separate worms provide compatible but different materials, to produce a single film in a flat die (stenter) or a sheath (blowing).
The complexes obtained by co-extrusion are multi-layer materials which may be homogeneous or heterogeneous.
