Tests performed by Food Safety Authority of the Canton of Zürich, the same entity that first identified the issue, determined that:
Thin multilayer plastic structures containing just a few microns of EVAL™ EVOH measured no MOSH/MOAH migration after 12 weeks at 60°C.
This corresponds to a period of 6.9 years at 25°C, or 10.7 years at 22°C.
The outstanding barrrier properties of EVAL™ allow optimisation
of the packaging structure, reducing costs and the amount of
necessary packaging, without compromising on the protective
Above: example of a barrier liner structure using EVAL™ EVOH as MOSH/MOAH barrier.
The same tests concluded that EVAL™ is barrier against not only MOSH/MOAH, but against any organic substance, including:
Test simulations showed that 5 µm of EVAL™ is enough to protect against the migration of these substances from primary or secondary packaging for up to two years storage at room temperature.
Our EVAL™ development team is able to provide our partners useful assistance with packaging design. We can help determine whether individual packaging structures with EVAL™ are compliant with current government MOSH/MOAH recommendations and regulations.
