Lorsque le sac à échantillon (100) est dans l'état enroulé, l'ourlet (109) est plié en deux, et la première ouverture (111) et la seconde ouverture (113) sont sensiblement alignées l'une avec l'autre. Le corps de sac (120) est plié pour former une bande allongée sensiblement parallèle à l'ourlet (109) ou enroulée en un rouleau. Le sac d'échantillon (100) comprend en outre des cordes de fixation (135, 141) pour maintenir le sac d'échantillon (100) dans l'état enroulé, empêchant ainsi le sac d'échantillon (100) d'entrer automatiquement dans l'état déroulé à partir de l'état enroulé.
