The wraps are off one of London Olympic’s big secrets... the design of the �fabric curtain that will encircle the �stadium.

The Wrap, to give it its official name, will comprise of 336 individual panels – each 25m high and 2.5m wide –to help the stadium become the stand-out visual centre piece of the Olympic Park.

It will be eco-friendly right down to the ink colouring which will be UV-curable. It should be completed by next spring and will also mask the arena’s tubular superstructure.

Games organisers LOCOG revealed Dow Chemical Company as the makers and they are meeting the �7m costs.

Using their own resins that need �fewer raw materials to manufacture, Dow’s panels will be much lighter than those made from conventional material and have a lower carbon footprint.

LOCOG chairman Sebastian Coe said the stadium will look spectacular and the wrap is “the icing on the cake.”

Dow’s George Hamilton said: “Our goal is to provide solutions that help make the Olympic Games more sustainable, safer and that will help improve performance.”
