Plastic packaging might seem impenetrable -- and sometimes nearly impossible to remove -- but water molecules can still pass through. And this permeability to moisture can limit the lifespan of a product. To better protect goods such as electronics and medicines, scientists have developed a new kind of packaging that incorporates a single layer of graphene. Their material reduces by a million fold how much water can get through.
