Single polymer polyester composites were recycled by compression moulding and extrusion. The recycled products were formed into films of 5 cm2 surface area and about 250 μm thick. The paper has presented the influence of recycled materials on the permeability of gases (O2, CO2, N2) and water vapour through the walls of the produced films. The influence of processing on the gas barrier of thin films was also determined. The results obtained were compared with the properties of commercial materials.
