Can the x-ray inspection equipment detect plastic and rubber?

CXR’s x-ray inspection machines can detect some plastics and rubbers, depending mostly on the contaminant’s relative density compared to the product. For example, a relatively dense plastic can usually be detected in less dense products such as fluids or powders. Additionally, if the contaminant is of a relatively large size, it is often possible to detect the void that it makes in a denser product.
