It is not necessary to remove general labels such as on soft drink bottles, wine bottles, jam jars etc. The main labels we would want people to remove are the full cover sleeve labels that you would find on items such as shampoo bottles, iced coffee bottles etc. The reason for this is that the full cover sleeve obscures the type of plastic used underneath and makes it difficult for those on the sorting line to identify the type of material. Most of these types of labels should have a perforated line to help make removal easier.
