Co-extrusion
The process of extruding two or more materials through a single die with two or more orifices arranged so that the extrudates merge and weld together into a laminar structure before chilling.
Coextrusion is another tool in the well-outfitted converter's tool chest,” according to Bruce Foster, technical sales manager of Mica Corp. “It provides better quality monolayer extrusion coatings over a wider variety of widths and line speeds; the potential to save on the amount of premium resins by filling with lower cost materials; and the possibility to make multi-layer, multi-functional structures in a single pass.”
