The addition of an iron oxide additive to the polyamide material allows detecable cable ties and other small components to be detected by metal detectors or X-ray inspection systems. Their blue color also enables easy visual identification during inspections. Using detectable cable ties in plant installations, machine wiring, and maintenance helps the agri-food and pharmaceutical industries comply with HACCP (Hazard Analysis and Critical Control Points) principles; a preventive system designed to identify and eliminate potential hazards or contamination risks in food production processes.
