ABSTRACT:
The film is obtained directly by extrusion from the lactic acid-based polymer plasticised beforehand by incorporation of 5 to 30% by weight of the polymer of a glycerol ester obtained from an acid containing 4 carbon atoms in its molecule.
The film has an elongation at break of more than 300% and is particularly suitable for the production of medical dressings.
