The invention relates to films of blends of polyhydroxy acid and other compatible thermoplastic polymers, and their production by melt processing the materials to obtain uniform composition, and forming the composition into a film of thickness from 0.01 to 2 mm. Such films are useful for conventional film uses where the film is to be discarded into the environment after usage. |
