Abstract

The invention relates to a method of treating at least one polymer item comprising treating the item(s) by liquid CO2 at a pressure of up to about 50 bars in a vessel, wherein the polymer item(s) is packed in a closed container during the treatment. The closed container comprises a wall wherein at least 10 % of the area thereof is porous wall section which is permeable to liquid CO2. The porous wall section has a pore size of up to about 500 μm. By the method polymer items can be treated by liquid CO2 in packed or pre-packed condition. Thereby the item(s) will be protected against recontamination.
