Applications / MOSH/MOAH / EVAL™ barrier performance against MOSH/MOAH


Protect food against mineral oil migration from recycled paperboard.

Confirming EVAL™ barrier performance against MOSH/MOAH

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 provide an effective functional barrier against MOSH/MOAH migration.

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 function.

EVAL™ as functional barrier against organic compounds

The same tests concluded that EVAL™ is barrier against not only MOSH/MOAH, but against  any organic substance and NIAS (non-intentionally added 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.

EVAL™ barrier is already commercially used to provide protection from MOSH/MOAH and other contaminants for packaging baking products, spices and milk powder. While effectively blocking contamination and odours from the outside, on the inside EVAL™ preserves aroma and vitamins.


MOSH/MOAH migration and packaging design

Our European EVAL™ Technical Centre in Antwerp, Belgium 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.
