Co-extruded and extruded high-altitude balloons and apparatus and methods for manufacture. A high-altitude balloon has a plurality of layers of coextruded balloon panel extrudate, a first one of the layers extrusion-bonded to a second one of the layers along a first edge, the second one of the layers extrusion-bonded to a third one of the layers along a strip spaced apart from the first edge, extrusion-bonding of successive layers alternating between the first edge and the strip, the first one of the layers and the last one of the layers extrusion-bonded together along a second edge.
