Reasons Why Zippers Are Broken

Zippers are one of the most essential parts of a backpack, yet they are also one of the most prone to breaking. There are many reasons why zippers break, but some of the most common include:

Become Stuck

One of the most common reasons why zippers are broken is because they become stuck. When this happens, it’s usually because there is something blocking the teeth from moving smoothly. This can be caused by lint, dirt, or even fabric getting caught in the zipper. If your zipper is stuck, you’ll need to clean out the teeth and make sure there isn’t anything blocking them before you can continue using your backpack.


Another common reason for zipper failure is tearing. This usually happens when the fabric of the backpack gets caught in the teeth of the zipper and pulls it apart. If your backpack is made of a fragile material, such as nylon, then it’s especially susceptible to this type of damage. You can prevent tearing by being careful not to catch the fabric in the zipper when you’re putting your backpack on or taking it off.


If you overload your backpack, it can put too much strain on the zipper and cause it to break. This is especially common if you try to force a large item into a small space. Make sure you pack your backpack carefully and don’t overload it to avoid breaking the zipper.

These are just a few of the most common reasons why zippers break. If you’re having trouble with your zipper, it’s important to identify the problem so you can fix it properly.

In most cases, you’ll be able to repair your backpack zipper yourself with a little time and effort. However, if the damage is too severe, you may need to replace the zipper entirely. Either way, following these steps, will help you get your backpack up and running again in no time.

If your backpack zipper is broken, there’s no need to panic. In most cases, you’ll be able to fix it yourself with just a few simple tools.

The first thing you’ll need to do is identify the problem. Is the zipper stuck? Has it torn? Or has it come completely off the track? Once you know what’s wrong with your zipper, you can start to troubleshoot the problem.


If your backpack zipper is stuck, the first thing you’ll need to do is clear out the teeth. This can be done with a toothbrush, a sewing needle, or even a piece of sandpaper. Once you’ve cleared out the teeth, try moving the zipper back and forth to see if it’s still stuck. If it is, you may need to lubricate the zipper with WD-40 or vaseline.


If your backpack zipper has torn, you’ll need to patch the hole with a piece of fabric. You can use a sewing needle and thread to sew the fabric in place, or you can use a hot glue gun. Once the hole is patched, try moving the zipper back and forth to see if it’s still stuck.

Come Off Track

If your backpack zipper has come off the track, you’ll need to reattach it. First, find the end of the zipper that’s still attached to the backpack. Then, line up the other end of the zipper with the teeth and push it back on the track. You may need to use a paperclip or something similar to help guide the zipper back on.

Once the zipper is back on track, close it up and make sure it’s working properly. If your backpack zipper is still not working after trying this, you may need to replace the zipper entirely.

If your backpack zipper is still not working properly after trying these steps, you may need to replace the zipper entirely. This can be done by taking your backpack to a sewing or repair shop. Replacing your backpack zipper is a fairly simple process, but it’s one that should only be attempted if you’re confident in your abilities.

Final Words

Backpack zippers are a pain to deal with, but with a little patience and the right tools, you can fix them relatively easily. Fixing a broken zipper is a much easier task than having to replace the entire backpack, so it’s definitely worth taking the time to learn how to do it.
