A security bag which exhibits a visible indication if an attempt has been made to gain access to the contents of the bag is formed of sheet material and has an opening (8) to enable access to be gained to the interior of the bag. The bag comprises first and second portions (3,4) of sheet material arranged to be superposable so as to close the opening. The bag is further provided with a tape (9) comprising a translucent or transparent substrate (11) differentially bonded to an opaque adhesive (13). The tape is located in a position such that, on superposition of the first and second portions, one face of the tape is adhered to one of said portions by said opaque adhesive and the other face of said tape is secured to the other portion by another adhesive (10).
