Biopolymers are polymers that are generated from renewable natural sources, are often biodegradable. They can be produced by biological systems (micro-organisms, plants and animals), or chemically synthesized from biological starting materials (e.g. corn, sugars, starch etc.).

Polylactide (PLA)- a nature derived polymer is one of the most demanding among biopolymers. It has wide range of applications starting from packaging to biomedical fields. Polymer Source possesses a patent on biomedical application of PLA and published number of research papers. Although not produced from renewable raw materials, polycaprolactone (PCL) is a fully biodegradable polymer. Polymer Source offer a wide range of PLA and PCL based products including homopolymers, block polymers, amphiphilic, functional and random polymers.
