It's the opening and closing of the lid that enables moisture to either
escape or enter. But yes, some plastics are permeable.

In low-humidity areas like Colorado, New Mexico, and Arizona, bullion cubes
that are past their expiration date don't dissolve in water very easily
as they have dried up to the point that they are only good for using as
slingshot ammo.
