    Biodegradable Poly (L-lactic acid) [PLLA]/Poly (bu-tylenes succinate) [PBS] or PLLA/Poly (butylenes succinate adipate) [PBSA] blend films were prepared. We have investigated the thermal and mechanical properties of the resulting films by using dynamic mechanical analysis, differential scanning calorimetry (DSC), tensile properties and morphological analysis. The experimental dynamic mechanical results suggested that blending of PBS or PBSA into PLLA caused an increase of the storage modulus (E') as a result of the crystallization of PLLA. From the DSC results, it was also demonstrated that the crystallization of PLLA was accelerated by blending it with PBS or PBSA. An improvement in the mechanical properties was observed by blending PLLA with PBS or PBSA. This improvement was believed to be due to the PBS or PBSA becoming the matrix in the blended films.

    The effects of solubility between film and base resin on the physical properties of film insert molded parts were investigated. Interfacial properties, which depend on solubility between film and base resin, had no effect on the static properties such as bending modulus. On the other hand, dynamic properties such as impact strength were considerably affected by interfacial properties. The interfacial properties were measured by a surface and interfacial cutting analysis system (SAICAS) and the thickness of the interfaces were measured by atomic force micrographs (AFM). It was believed that the peel strength was not accurately measured by SAICAS because the thickness of the interfaces were several hundred nano meters. It was clarified that SAICAS is not appropriate for measuring the interfacial strength.
