The bag has a body that is made from a very strong material. It has an open edge (5) and a first ring shaped fold (6) is fixed in position adjacent to this edge. A second fold (7) is arranged parallel to the first and a certain distance from it. A tamperproof closure seal (8) is located in between the two folds. The folds prevent the seal being slid off the bag in either an upward or downward direction. The folds are fixed to the exterior of the bag and attached to it along their entire length. ADVANTAGE - Provides a bag that is simple, efficient to use and has a low cost.
