ABSTRACT:
A bag or similar portable container having a wall or walls surrounding an internal space accessible through an opening (4) in the bag, the wall or walls incorporating or being lined with one or more layers (6) of high tensile strength and high stretch resistance material such as to be capable of resisting penetration by a bullet. Preferably, a single multi-layer sheet (6) is used to form the wall or walls (9) by folding the sheet at the corners (32), thereby avoiding joins that would be vulnerable to penetration. Preferably, the penetration resistant material (6) is backed up by one or more layers (11) of an impact absorbing material, such as polycarbonate sheet material and foamed plastics material. The layers of penetration resistance material (6) and impact absorbing material (11) may be separately formed as removable inserts that are used to line the bag.
