OTHER POLYETHYLENE VESSELS

      

Polyethylene vessels such as drums and IBC's, have been used for transport wine and for short term storage for many years. However it is a common experience that wine stored in these does not keep well.
 
In fact, common polyethylene containers like drums & IBC's are too oxygen permeable to mature wine correctly, they:
  • are too thin walled for their volume, i.e. too 'oxidative'
  • have unsuitable shapes, i.e. have recesses or projections which trap air
  • are difficult to clean internally, having small openings
  • are made from common grades of PE which are incorrect for maturation
  • often exhibit a 'burnt wax' taint
On the other hand, Flextank HDPE Vessels, are engineered to mature wine by using a correct balance between material permeability and wall thickness, vessels surface area and volume.
