Quality Assurance Before and During Bulk Transport
Dissolved oxygen posted a major chemical threat during bulk wine shipping. Defective seals of ISO tanks or permeability of flexitank material can allow oxygen entry that may degrade the wine. Regular checks of seals minimise this risk. Also introduction of new construction materials for “Flexitank” can reduce oxidation. For instance Environmental Packaging Technologies, USA bulk wine shipper, use flexitanks that were made from polyethylene film with an additional ethylene vinyl alcohol copolymer (EVOH) barrier. These tanks achieved an oxygen transmission rate of 1 – 2 ml per square metre per 24hour.
