(PackagingNews) -- Plastic
packaging specialist Nampak is looking to trial milk bottles with 30% recycled
content after a university study found that 50% recycled content was a feasible
target for HDPE milk bottles.
Using post consumer food grade rHDPE pellets, the experimental work assessed
the properties of blends of virgin HDPE with between 10% and 50% rHDPE, and also
quantified the effects on material properties of five thermal cycles through an
extruder.
The researchers concluded that the recyclate grades studied had very
similar properties – including flow behaviour, quality and molecular and
chemical structure – to the virgin materials.
