Tall, rigid containers are used frequently in the food industry and are commonly defined as containers that are taller than they are wide. Metal cans, doypacks, cartons and composite cans are commonplace containers that fall into this category, as are glass bottles and jars. These types of applications, once filled, are routinely checked by x-ray inspection systems for contaminants such as glass, metal, dense plastic, mineral stone and calcified bone.
However, there are challenges associated with different packaging types. Different packaging materials, for example, allow x-rays to pass through them to varying degrees – with some absorbing more than others – which have a direct effect on detection sensitivity. Factors such as product density, depth and orientation to the x-ray system are also key to consider in contaminant detection. Each type of packaging can be defined as low, medium or high density, and will determine the best machine for your operation.
