Laminated board or corrugated liners are used to line baking trays or as the tray for baking, eliminating the need for oiling, spraying, or washing of trays. Simply remove liner and decorate cake. Corrugated liners provide packaging and structure for slab cakes through the building and decorating process for layer cakes. They can also be used as the shipping container eliminating further steps like depanning and additional packing processes. Single-face liners are ideal for sturdier products, which require pan lining, like fruit cake or loaf cakes and can provide festive looks with custom colors available.
