Biopolyesters, such as PLA, PHA or PBS, often have limitations in terms of flexibility and elongation at break, essential properties for certain applications requiring flexible, deformation-resistant materials.
For example, PLA is naturally rigid and brittle, making it unsuitable for applications involving repeated mechanical stress or frequent bending.
NaturePlast and its BiopolyNov R&D laboratory have developed formulations to specifically address this issue and compensate for the limitations of these bioplastics.
