After a survey of the mostly utilized recycling methods for fibres and bottles, the possibilities of recovering films are discussed in more detail. This presentation describes primarily the melt‐recovery method, which is used by us and by other manufacturers. During this process the greatest difficulties arise from the presence of impurities and contaminations. The influence of these determining parameters on the recycling process and on the re‐usability of the recovered PET are elucidated, with special emphasis on the role of the oligomers.
