The difference is clear

The new element introduced is the Smartcap - a universal plastic reusable capping tray. When used in conjunction with the Smartpad - a vital Smartstak component - the Smartcap creates another complete, intelligent glass bottle packaging system which eliminates cardboard capping trays used predominantly in Europe, in addition to shrink wrapping.

The Smartpads are injection moulded, waved edged layers in the Smartstak system which ensure pallet stability and allow bottles to be added to each layer or even complete layers added to a pallet.
