HIGH-RESOLUTION XPS OF RECYCLED POLYETHYLENE

High resolution monochromated XPS has been used to investigate the sur face science of a variety of recycled polyethylene films (both filled and unfilled). The starting materials for these studies were obtained from reclamation and recycling of polyethylene sheets used in large vo lume in the Horticultural Industry. The level of surface functionalisa tion and contaminants found in the recycled materials make them potent ial candidates for both primary and even 'premium' recycling opportuni ties in areas where surface properties are the dominant effect.
