The films yielded were cast from heated and alkaline aqueous solution of SPI, glycerol and Gen and then dried in an oven. Total soluble matter, water vapor permeability and mechanical properties were improved by adding small amounts of Gen. These properties were not significantly affected (PP0.05) by additions exceeding 2.5% (w/w of SPI). The opacity and cross-linking degree were linearly in
