Summary: | A profiled extrusion replication process is disclosed that includes steps of (a) extruding a molten material through an extrusion die having at least one profiled die lip to form a molten extrudate having first and second major extrudate surfaces and having a first structural feature in the first major extrudate surface; (b) bringing the molten extrudate into contact with a tool surface comprising one or more second structural features so as to cause a portion of the first structural feature in the first major extrudate surface to contact the one or more second structural features on the tool surface; and (c) cooling the molten extrudate to provide the structured film. Structured films and apparatus for making structured films are also disclosed. |
