锡纸 (xī zhǐ): アルミホイル

I wrapped the fish in tinfoil and then put it in the oven.

Before baking potatoes, remember to line the baking tray with a layer of tinfoil.

Mom wrapped the leftovers in tinfoil and put them in the fridge.

Tinfoil can also be used to wrap food to keep it fresh.

Please give me a sheet of tinfoil; I want to bake a cake.
