Aseptic pouch product. X-ray has a high level of false positives. Maintenance has fine-tuned and optimized but the high number (0.54%) of false positives continue. Current policy is disposal.
Can I take x-ray kick outs and run them through three times with all three successful passes allow the product to go to commerce and a single rejection out of the three being destruction?
What other methods do you all use to mitigate false positives on x-ray or metal detection?
As others have suggested, I would be very reluctant to release any package that had been rejected without knowing for certain WHY it had been rejected.
0.5% sounds high for false rejects, but we don't know the nature of the product or packaging. Some of the items we run can come close to that with metal detectors, but that's a result of moisture/salt content.
Fortunately our product allows for rework, so packs are opened and individual pieces are subject to detection to search for potential FM.
