This disclosure describes co-extruded multilayer articles including at least one continuous layer and one discontinuous layer, as well as systems and techniques for the manufacture of co-extruded multilayer articles. For example, a co-extruded multilayer article is described that includes a body having a plurality of layers, where a first layer of the plurality of layers is formed from a first material and is continuous along a longitudinal axis of the body, and a second layer of the plurality of layers is formed from a second material and is discontinuously co-extruded along the longitudinal axis.
