Metal detectors and X-ray equipment have been in use by processors for decades to help keep the food supply chain safe and free from foreign objects. However, changing needs have been the catalyst for shifts in selection and use.
In recent years, food processors have been switching from metal detection to X-ray systems for multiple reasons. First is the growing use of metalized film and foil, or other packaging types such as cans or metal closures. Metal packaging poses problems for metal detectors but works very well with X-ray systems.
