Aluminium foil will protect against electrostatic discharge as well as, if not better than, an anti-static bag. (An anti-static bag is only slightly conductive, so a direct ESD event onto it can be transferred to the board inside.) But aluminium foil is NOT suitable for boards that have power sources, such as lithium backup cells, because it will short them out and discharge them if it makes contact with them. Boards containing supercaps for short-term backup are safe if the supercap is discharged.
-I would fold the tin foil at least twice (forming four layers) before wrapping it round the board, otherwise it can rip and leave areas unprotected.
