Hi,

Polylactide (PLA) is a biodegradable, thermoplastic, aliphatic polyester derived from renewable resources, such as corn starch (in the U.S.) or sugarcanes (rest of world).

I am interested in the short and long term water permeation (water vapour transmission rates) properties in humid conditions in the temperature range from 0 to 40 degrees Celsius.

Furthermore, I assume that the material chemically ages in humid circumstances, hence insight in the kinetics and duration of this Polylactide ageing is also of my interest.

Last but not least: can we make laminates of Polylactide polymer with other materials that improve the barrier and/or chemical degradation behaviour, which still own the Cradle to Cradle (CTC) properties (at least to an important extent).

Thanks in advance for your independent and rigorous information.

Regards,
Anna
