Description
Air oven treatment of locally available polyethylene (PE) plastics branded as Lucky bag and Anchor was conducted as abiotic degradation process in order to evaluate the extent of their thermal degradability. Air oven treated Lucky bag films indicated the decreased values in tensile
strength of 2.4MPa from the original value of 16.1 MPa and 83%loss of the original value of elongation at break while air oven treated Anchor films the tensile strength decreased to 5.7 MPa from the original value of 22.9 MPa and •99%: loss of the original value of elongation at break resulted• during the two month degradation course. The results of SEM and EDXRF analyses showed surface erosion, diffusion and leakage of additives incorporated in the plastic films. The results in FTIR spectra clearly indicated the progressive changes in chemical structure in the internal material of plastic films with the occurrence of small transmittance.
