Our plastics and rubbers are very detectable and contain enough metallic content to make them jump to a magnet. However, their detectability is very much dependant on the sensitivity of your metal detector or x-ray inspection system. Different aperture sizes, line speeds, food types and packaging types all have an impact on the sensitivity of your inspection system. The more sensitive your system, the smaller the piece of detectable product you will be able to identify. Testing in your own environment is highly recommended.
