Layered composites may be subject to detachment and delamination. Packaging for foods may break down to let in moisture, dirt, or bacteria. 3D-techniques based on X-rays can reveal weaknesses in lamination or welds and lead the way towards improved products or process parameters. The insights offered by these tools can also accelerate and improve the design phase. In this way, the methods can make development cheaper, as weaknesses or issues with new products can be mapped or substantiated at an earlier stage.
