ABSTRACT Packaging Smoking Material There is provided a pouch 10 containing tobacco 11 and a moisturising element 13 containing a measured quantity of water in a fibrous pad. This element is sealed from the tobacco 11 by a vapour permeable liquid barrier 14 comprising a vapour permeable outer layer 15 and an inner, degradable liquid barrier 16. After a predetermined period of time the barrier 16 starts to degrade or dissolve thus allowing the moisture in the element 13 to pass into the tobacco 11 as a vapour through the vapour permeable layer 15.
