    Seal valves, latches, containers, and other devices with these traceable, tamper-evident seals, which are designed for food, pharmaceutical, and other sanitary environments. They contain metal and chemical additives that will set off metal detectors and show up on X-rays if any part of them falls into your line. Use them to help you comply with Hazard Analysis and Critical Control Point (HACCP) programs to make sure contaminated food doesn’t leave your plant. Available in a variety of colors for color-coding the different lines and areas of your plant, they help you follow Good Manufacturing Practices (GMPs).
    These seals cinch tight like cable ties and have a pull tab to remove them without tools. They’re stamped with the message "SEALED" and numbered sequentially, which helps you track if any seals have been tampered with. Not offered blank for security reasons.
