The possibilities of recycling milk-contaminated HDPE were investigated. Bottles were blown of respectively untreated, caustic-washed and caustic-washed/steam-stripped/air-dried recycled material. The migration characteristics of the different bottles were compared using various food simulants, as well as their sensorial and mechanical properties. From the analytical and sensorial experiments, it was shown that the untreated and caustic-washed recycled material could not be considered as a food packaging material. A high number of compounds able to migrate were detected, causing an off-flavour which could easily be recognized. The steam-stripped recycled material however, seemed to perform almost as well as its corresponding virgin material. Only low amounts of compounds able to migrate could be detected, resulting in a packaging material characterized by excellent sensorial properties which could not be distinguished from its virgin material. Furthermore it was proved that the mechanical properties of the recycled material did not change during the recycling process. |
