b at the airport or customs: These aluminium bags have an absolute radiation impermeability, so that the contents are protected from external influences and cannot be X-rayed. Aluminium foil was originally developed for military purposes, but after a study - under the most difficult conditions - during the Second World War, the industry decided to use this high-quality foil for sensitive goods as well. The aluminium bags are radiopaque, as well as absolutely air, water and odourproof.

To close, lightly iron the bag with an iron.

Instructions: Set the iron to the highest setting and warm up briefly. After it has reached the desired temperature, iron the open edge of the aluminium bag so that a secure edge of approx. 5cm remains.
