New white paper explains how to ensure optimal detection of glass contaminants in glass packaging

This 14-page white paper 'How to guarantee all-round glass inspection' begins by explaining why glass packaging is rising in popularity. It then goes on to highlight the dangers of glass-in-glass contamination, describing how certain production processes increase the risks. The first part of the paper concludes by exploring the ability of x-ray technology to detect glass contaminants in glass packaging and considers the factors that affect detection sensitivity.

The second half of the paper takes a detailed look at the latest x-ray solutions available for glass-in-glass detection including systems with single beams, split beams, combination beams and angled beams. It explains that, as well as detecting physical contaminants, modern x-ray systems are multi-tasking defenders of product and brand quality. In a single pass, at high line speeds, x-ray systems can simultaneously monitor fill levels, detect damaged containers and check closures.

Demand for glass packaging is rising globally but despite its popularity, glass poses a significant safety risk and the effects of glass-in-glass contamination can be highly damaging. In 2014, more than 10% of physical contamination incidents reported to the UK's Food Standards Agency (FSA) were a result of glass contamination¹.

Food and pharmaceutical manufacturers are increasingly installing x-ray inspection equipment to protect consumers, reduce the risk of product recalls and comply with global safety and retailer standards. However, glass containers are indisputably one of the most challenging types of packaging to inspect, primarily because the main contaminant is glass - the same material and density as the packaging. Problems also occur due to the density of the packaging and because the base, sidewalls and neck of glass jars can all cause ‘blind spots’ - obscuration of the visual field. This means key parts of the product/packaging can mask dangerous contaminants.

Finally, the paper recommends several transport system design features for optimal glass-in-glass inspection, and includes a useful appendix 'Setting the Critical Limits' which outlines the correct protocol for glass-in-glass testing.
