Protection and barrier properties Paper and board as such are poor barriers. They are hygroscopic and absorb moisture. In addition, about half their volume consists of pores. This means that they allow air and other gases to flow through very freely. To exhibit any degree of barrier properties, paper and board require treatment in some
