Combined with PE + PP, aluminium oxygen resistant barrier is used for oxidizing prevent. At the same time, it ensures the strength of the Flexitank (Flexibag).
The oxygen transmission rate of aluminium oxygen resistant barrier is ≤0.5 cm3/m2·24h·0.1Mpa, which is 50% lower than the conventional EVOH barrier.
Compared to EVOH barrier, aluminium oxygen resistant barrier is much more durable. The tensile strength increases by more than 30%. The longitudinal tensile strength is 33.88MD(N/15mm), while the transverse tensile strength is 30.72TD(N/15mm).FDA, EC approved, food grade. Special Designs for securing hygiene. Strong rigid frame bulkhead.
