Flexible Packaging Requirements for Different Products Quiz

Aluminium foil, EVOH (Ethylene Vinyl Alcohol), PVdC (Polyvinylidene Chloride), aluminium metallised PET (Polyethylene Terephthalate), SiOx (Silicon Oxide) coated PET, or wax.

EVOH offers excellent gas barrier properties but deteriorates in high humidity environments, so it's often sandwiched between layers of PE or PP to provide protection.

Some end-users discourage the use of aluminium foil due to difficulties in recycling post-consumer waste management systems.
