Materials

ZORK is made of three parts. The primary functions of the three components are:

Cap
The polyethylene cap provides a tamper evident clamp that locks the closure onto the CETIE band of a cork mouth bottle.

Foil
The aluminium foil is welded between the inside of the cap to provide an oxygen barrier equivalent to a screw cap.

Plunger
The polyethylene plunger is clipped into the inside of the cap and welded to the foil. The plunger creates the 'pop' on extraction and reseals the bottle after use. The plunger material has been tested by the AWRI and shows no negative affects on the wine.

  • All materials are approved by the American FDA board and European EEC board. Only the Plunger is in contact with the wine.

  • This Polyethylene based material has been independently tested to ensure it has no negative affects on the wine. 38 Month Test Results Summary (PDF, 127k)

  • Polyethylene is one of the purest forms of polymer available and has been used in the food and beverage packaging industry for many years.
