How to Fix a Zipper on a Backpack that Separated

Whether it is a zipper on your backpack, zip wallets, or just one of your purses, a zipper can easily be separated if it is used frequently. This happens because the teeth of these zippers might have loosened up and now it just needs a little clamping to get it back to working properly.

  1. A pair of pliers
  2. Utility scissors 
  3. A sewing needle and thread

Once you have gathered the stuff as mentioned above, start working your way through by following these steps:

Step 1: Inspect the root cause of the problem

It’s important to know the reason for the breakage before getting the zipper fixed. However, a zipper may come off from one side mainly due to a broken track, or maybe because of torn or bent teeth. 

Address the issue first so that it is prevented from occurring again.

Step 2: Give a small cut

Begin by bringing the slider right to the bottom where the zipper will stay once it is widely opened. Then, take a pair of utility scissors and cut on the opposite track near the slider, try to be as close as possible. 

Step 3: Re-attach the zipper onto the track

Now, after cutting a bit over the track, you need to attach the slider back onto the track and see if the zipper closes back up smoothly as it used to, before coming off from one side. 

If not, use the pair of pliers to clamp the zipper on each side so that it stays tight around the track. 

Step 4: Sew back with needle and thread

Now, to give a new stop to the slider, you need to sew a little over the area where you initially gave a cut. This will act as the new stopper for the zipper and prevent it from coming off the track.

Step 2: Get rid of some teeth

Get the pair of pliers and start removing about 4 to 6 teeth from each side of the track. 

Carefully pull each tooth one by one and leave some space for sewing in case the fabric rips a bit. 

Step 3: Start sewing the ends

Now, place the slider back onto the track and then sew over the ends from where you took off the teeth. This is to prevent the slider from sliding off the track. 

Make sure the thread and the backpack have the same colors so it does not look odd when you sew the tracks.
