BioSolar Inc., which has developed solar power cells using plant material, did its development and testing at a Marshall and Williams laboratory for making biaxially oriented film in Woonsocket, R.I.
Santa Clarita, Calif.-based BioSolar contacted Parkinson Technologies Inc., which makes Marshall and Williams orientation equipment, known as tenter frames. Product trials included running films of different materials. The goal was to use biaxial orientation to add strength to bio-based materials.
The pilot lab has a complete inline system for coextruding film and sheet with as many as five layers, with either machine direction orientation or transverse direction orientation.
