More and more milk producers turn from cardboard to more elegant transparent PET bottles decorated with stretch sleeves applied by labelling machines, which require neither heat (they exploit the elastic properties of PE) nor glue (no glue migration through the bottle walls means the milk remains untouched). Stretch sleeves represent an alternative to more expensive labelling systems, whilst offering high-quality flexo print up to 10 colours and good transparency; moreover, they are environmental friendly because, thanks to the different specific weight, they can easily be separated from the container.
