Le PLA est sensible à l'hydrolyse (acides, bases, eau chaude) et se dégrade rapidement en compostage industriel. Résistance aux solvants et huiles limitée. Ne pas utiliser au-dessus de 50 °C. Inertie chimique correcte pour les emballages alimentaires à T° ambiante.

Frequently asked questions
GF grades require higher injection pressures. Strongly anisotropic shrinkage (perpendicular to fibres > along axis). Increased nozzle and mould wear — nitrided steels recommended. Drying identical to base grade.
PLA is industrially compostable (EN 13432) in 12 weeks at 55 °C. Mechanical recycling is possible but the systems are not well-developed as PLA contaminates PET and PE streams. Specific collection systems are therefore required.
PLA is FDA and EFSA approved for food contact at ambient temperature. Used in cold food packaging (salads, yoghurts). Do not use in contact with hot food (> 50 °C) or in microwave ovens.
