When opting to produce multilayer sheet, a properly working feedblock or black-box is needed in order to produce the correct distribution of each of the layers. Whether you are looking for a basic 3 layer configuration to add a virgin top layer or a colour top layer to your sheet, up to more complex configurations for barrier sheet and adhesives, MEAF can provide you with co-extrusion sheet line to fit your production needs, such as:

1. Two/multiple coloured sheet (side by side extrusion);
2. B-A-B (A-B-A) or B-A-B-C layer configuration for regrind material solutions;
3. EVOH barrier sheet;
4. G-PET and so called PETGAG sheet;
5. A coextruded layer with additives like anti-blocking, usually done with PET material.

As with flat dies, the feedblocks internal channels are computer calculated for optimum distribution of the materials. The layer distribution is arranged by either layer selector plugs or with valves.
