The invention concerns a safety envelope (20) formed by a sleeve (21) made of heat shrinkable plastic material, equipped on its inner surface with a tear strip (22) and a metal-coated identifying strip (23). The invention is characterised in that the metal-coated strip (23) is non-adhesive, and is sandwiched between the sleeve (21) inner surface and an adhesive surface of the tear strip (22). The tear strip (22) overlaps on the metal-coated strip (23) two sides so as to adhere to the sleeve (21) internal surface via zones located on either side of the metal-coated strip (23). |
