All technology has its limits. Whether it is X-ray inspection systems, magnetic field detectors, colorimetric sorters, they are sometimes unable to detect certain foreign bodies encountered in industry.

The following is a representative list of foreign objects that are undetectable due to their low density and small size:

Hair, fibres, wood, insects, fruit stones, glove and blouse fragments, paper, plastic film, film/aluminium complex, slag*, cartilage.
