Abstract

Extraction studies carried out on some polyethylene films and containers obtained from different sources indicate that the % of solids (by wt.) extracted by hexane at 50 degree C and xylene at 25 degree C are, in general, well below the limits of 5.5% and 11.5% resp. specified by Indian (ISI) and US (FDA) regulations. The % of extractives obtained with hexane depends on the nature of the polymer (high or low density), thickness of the film, and the type of pigment added to the film. Evaporation of xylene under O2 or N2 gave similar extractive values.
