Bag

Abstract

A bag ( 1 ) has side walls ( 3, 4 ) that are substantially impervious to moisture. The bag has an opening ( 6 ) at one end that is adapted to be sealed. A portion ( 11 ) of a side wall includes a substantially transparent material ( 12 ) which is substantially impervious to moisture. A moisture indicating material ( 13 ) is mounted within the bag adjacent to the transparent material ( 12 ) to enable the moisture indicating material ( 13 ) to be viewed through the transparent material ( 12 ), and at least a portion of the moisture indicating material ( 13 ) is exposed to air within the bag ( 1 ).
