This is designed to retain dimensional stability and its shape. The form is deposited from the mould into a female mould which then proceeds through the drying oven.

The fibrous slurry is pumped into a vat. A plenum, with product moulds mounted on it, passes through this mixture. The liquid pulp is drawn onto the moulds by vacuum and the water is simultaneously extracted, leaving a very soggy, even layer of pulp on the fine stainless steel mesh covering the mould.

The wet product is transferred onto a “carrier belt” that transports it through a drier (oven) at extreme heat to dry the product to “touch-dry”. This extreme heat causes the product to undergo considerable shrinkage.

The product is then ironed into the perfect shape by an afterpress, using a combination of heat and extremely high pressure.

The product is then either fed into a printer for customised logo’s, trademarks and product description or packed for despatch.

The Guardian 30 egg tray is the first egg tray to be produced by this method in the world.
