Although PLA fibres are used in different textile applications as, for example, non-woven textile for clothes, they achieved their first commercial success as resorbable sutures. One of the first commercially available fibre-formed bioresorbable medical products is based on copolymers of GA in combination with L-lactide (Vicryl) [67]. Fibres can be produced both by solvent and by melt-spinning processes and drawn under different conditions to orient the macro molecules [7].

PLA can be processed by extrusion, thermoforming, injection, blow moulding, fibre spinning or stretehing. It is printable and heat sealable. The actual or potential applications are found in the crop and food sectors (films, food packaging, soft drinks) and for non-woven materials in hygienic products. The properties of biocompatibility and of bioresorption of PLA permits the development of suture threads and ehps, orthopaedic fixations (screws, pins) and of resorbable implants (Clarinval, 2002). Some of the main products are given below.
