A die (12, 12', 112) for coextruding a plurality of fluid layers includes one or more distribution plates (32, 132), for forming relatively thick layers, and a microlayer assembly (34, 134) for forming a plurality of microlayers. The die (12, 12', 112) includes internal fluid passages (42, 62, 142, 162) and/or forming surfaces (172) to allow the microlayers to assemble into a microlayered fluid mass prior to merging with the relatively thick layers from the distribution plates (32, 132). |
