Is there a way to extend the shelf life of a bag of cable ties after they have been opened?

Because cable ties are made of nylon, they will have a natural tendency to lose moisture over time as they are exposed to the air.  Drier environments will speed up this process.  To help extend the life of a bag of cable ties after they have been opened, add a drop or two of water to the bag, and then seal the top of the bag shut with tape.  Make sure there are no other holes in the bag.  If this is done each time a bag of cable ties is taken out and used, the shelf life of the ties will be greatly extended.

Standard shelf life on cable ties is 1 year from the date of production.

What is the shelf life of the Liquid Tape?

Shelf life is 12 months from the date of manufacturing.  The date of manufacturing is listed on the top of the cover.  The date code will be a 5 digit number.  First 2 digits of the sequence of numbers will be the year of production, and the next 3 letters will be the actual day of the year it was made.  For example, 10513would mean that this particular batch was manufactured on the 105th day of 2013.

To extend the shelf life, when storing the product, store the can upside-down.  This will create an internal seal and will help keep the tape for thickening and hardening over time.
