Poly L Lactic acid - Biopolymer is a Biomer® P226. These resins are produced from renewable resources. Renewable feedstock meets the criteria of sustainable response. In addition they do not add to the CO₂ concentration in the atmosphere (“Responsible Care”).
Components made of this resin are waterproof. These resins are inert towards water, even after extended exposure. They are also fairly resistant towards fats and oils. Thus components made of these resins protect sensitive products against moisture and oily soiling.
Components made of this polymer can be autoclaved. Components made of PHB thermoplasts retain their original shape at 121 °C or 132 °C. Because of this perishable goods can be canned into packages produces of PLLA and preserved by steam sterilization.
Components made of this polymer are toxicologically safe. The monomer as well as the polymer are natural components and metabolites of human cells. They are not toxic even at high concentrations. Thus PLLA formulations can be used for articles which come into contact with skin, feed or food.
Components made of PLLA are fully biodegradable. In composts where nitrogen and phosphates are abundant, articles made with Biomer® resins are taken up by bacteria and fungi as nutrient. No toxic by-products are accumulated. Under optimal conditions thin walled injection molded articles are composted within 2 months.
