Nylon 6/6 is the industry standard for cable ties because it is tough, flexible, and resistant to chemicals. However, nylon is a hygroscopic material—meaning it naturally absorbs and releases moisture.
If a cable tie loses its moisture content, it becomes brittle and prone to snapping during installation. To ensure your cable ties remains reliable, follow these essential storage guidelines.
Storage for Unopened Packaging
Manufacturers and suppliers of cable ties typically seal cable ties in airtight plastic bags with a specific amount of moisture (usually around 2,5% by weight) to keep them flexible. This is also the very reason why you might see small white specks, or residue - as that is from the water being sprayed on the cable ties before the bag is sealed.
Keep the Seal Intact: Do not open a bag until you are ready to use the ties. The factory seal is your best defense against environmental drying.
Temperature Control: Store bags in a cool, dry place. Ideally, the temperature should be around 23°C. Avoid storing them near heaters, radiators, or in direct sunlight, as heat accelerates the evaporation of internal moisture.
First In, First Out (FIFO): Practice inventory rotation. Even in sealed bags, nylon can degrade over several years. Use your oldest stock first
Storage After the Packaging is Opened
Once the packaging has been opened, the nylon begins to equilibrate with the surrounding humidity. In dry climates or heated indoor environments, this can lead to "brittle failure."
Reseal Immediately: If you only need a few ties, squeeze the excess air out of the bag and reseal it with a clip, tape, or a zip-top closure.
The "Water Trick": If you are in a very dry environment, adding a few drops of water (distilled is best) into the bag before resealing can help maintain the necessary humidity levels.
Avoid Bulk Bins: While it’s tempting to dump all your ties into an open-top organizer bin, this exposes them to constant airflow. If you must use bins, ensure they have tight-fitting lids.
Pro Tip: If you discover a batch of ties that has already become brittle, you can often 'revive' them by placing them in a sealed container with a damp cloth for 24–48 hours. This allows the nylon to reabsorb moisture and regain its flexibility.
