Tivoli clarified polypropylene (PP) reusable cup, injection moulded with PP in-mould label (IML) graphics. Using a single material throughout ensure compatibility of this returnable cup for recycling once it reaches the end of its useful life. However, the ink used for the decoration is trapped between the IML film and moulded cup, and so becomes contamination during recycling and means the cup cannot be recycled back into the same product.
