In ozonation process mixing of artificial films up to 10 min reduces the contact angle from 78 to 62, and also increases the hydrophilicity of CP films. The previous studies also performed show that the arti-ficial PVDC films easily settle down by the same. The effect of ozonation after the wet gravity separation on light PPW films obtained from an actual PPW recycling plant was also evaluated. Although actual light PPW films contained 1.3% of CP films however in present case all the CP films were removed from the PPW films as a settled fraction in the combination process of ozonation and wet gravity separation. The combination process of ozonation and wet gravity separation is the more beneficial process in recov-ering of high purity PP and PE films from the PPW films.
