The coextrusion process combines the output of two or more extruders. The finished product, in this case tube or sheet, is distinguished by discrete layers of material. The number of component layers theoretically is unlimited. Experience to date with the blown film process has been predominantly in the two- or three-layer range; the number of layers is limited by current equipment design technology.
procedure to extrude/combine two or more monofilms together in one
The extrusion of two materials simultaneously from a single die in such a way that the two separate materials fuse together to form a single structure.
Simultaneous extrusion of two or more different thermoplastic resins into a sandwich-like film with clearly distinguishable individual layers.
Two or more polymers extruded and combined in a die, each forming a distinct layer in the final film.
Plastics processing technique to produce multi-layered objects; coextrusion is used in the production of pipes, films, gas tanks, bottles, etc
Two or more different materials simultaneously extruded into a composite film.
Blowing technology that allows fuel systems to be made of multilayer plastics, and especially to integrate barrier layers to meet increasingly stringent environmental regulations.
nbspExtrusion of composite film consisting of several layers of polymer of different colours and/or types. The individual layers are bonded thermally.
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.
