Abstract:
1. A bio-based polymer panel having multiple laminated layers with a combined thickness of at least about 0.15 inches, comprising: a first biopolymer resin sheet comprising a biopolymer resin that is not derived from petroleum-based materials; at least a second biopolymer resin sheet comprising the same biopolymer resin, the first and at least a second sheet having been laminated together below the melting point of the biopolymer resin without intervening adhesives, so that the first and at least a second sheets comprise a single unitary panel with multiple, laminated resin sheet layers; wherein each of the laminated resin sheets in the panel has been heated past its respective glass transition temperature without reaching the melting point, and rapidly quenched, such that the laminated resin sheets of the bio-based polymer panel resist delamination, and such that the bio-based polymer panel exhibits substantially no clouding resulting from crystallization therein.
