How To Fix A Zipper On A Backpack: Beginner’s Guide


On any backpack, the zipper is one of the most important parts. For you to keep your gear inside the main compartment on your hiking backpack, the zipper has to be functional. It is not uncommon for backpack zippers to fail. When this happens, backpack zipper repair becomes necessary. 

In this article, you will learn how to fix a zipper on a backpack. Since we already know that different zipper issues require varying solutions, we will show you the different fixes you can use to make the zipper functional again. 

How to Fix A Zipper On A Backpack – Solutions for the Main Zipper Problems 

1. Lubrication Problem 

If the zipper on your backpacking backpack feels broken because it does not move up and down, this is probably a lubrication issue.  To perform backpack zipper repair on a zipper that does not move, you can use the solutions below: 


Graphite offers great lubrication for zippers. If you have a number 2 pencil, simply rub its tip in the area where the zipper is stuck. 

Once you are done with applying graphite, try moving the zipper. If the issue was a simple lubrication issue, you should be able to pack your backpack and embark on your backpacking trip.  

Laundry Soap 

If graphite fails to fix the lubrication issue, you should consider trying laundry soap. Put a little laundry soap in a dish and then add a few spoons of water. Mix until you have a semi-thick solution. 

Take a cotton swab and drench it in the solution. Use the cotton swab to wet your zipper and then try to move the zip again. 

Candle Wax/Crayon

Another ideal way to perform backpack zipper repair when the zipper is stuck is to use wax. Household wax is usually effective. However, if you do not have household wax, you can use a wax crayon stick or an old candle. Simply rub the wax stick where the zipper is stuck and then try to move it. 

2. Bent Teeth Problem 

If the backpack teeth are bent, lubrication won’t be a solution. However, learning how to fix a zipper on a backpack if the problem is bent teeth is also easy. 

The only thing you will need is a pair of pliers – if you have a backpacking repair kit, you should have the pliers. Simply grip the bent tooth with your pliers and maneuver it so it straightens. You may need to repeat this a couple of times to fix the tooth. However, try to avoid pulling too hard as the tooth could end up coming out of the tape. 

3. Broken Pull Problem 

The easiest way to fix a broken pull is to use a paper clip. Simply open one end of the paper clip and put it through the hole where the zipper pull goes. Alternatively, you can convert a telephone wire connector, keyring, or anything small, malleable and nimble into a zipper pull suitable for your type of backpack

4. Broken Slider Problem 

If your travel backpack has a broken slider, the easiest backpack zipper repair you can use is to replace the slider. To someone learning how to fix a zipper on a backpack for the first time, this may sound complicated. If you have pliers, the process will be extremely easy. 

Simply use the pliers to cut the broken slider off. Next, reattach the new slider by sliding it slowly on to the zipper’s teeth. If you can get the new zipper to go into the right grooves and hit the ideal angle, this shouldn’t take long. 

5. Completely Damaged Zipper 

If the zipper on your tactical backpack is completely damaged, replacing the whole zipper may be the only solution. You can use your pocket knife to carefully cut the damaged zipper out.  

Next, take the new zipper and look for its center. Match the zipper’s center with the top center on your backpack. Start sewing from the top center down one side, again start from the top center and work down the other side. 

Be sure to avoid uneven sew lines and gap forming. Also, ensure that the zipper rachet and the hauls are nicely situated. 

After sewing the zipper on the outside of the backpack, flip the backpack inside out and repeat the process on the other side. Start from the top center and work down on both sides. Be sure to keep the zipper closed when sewing it. 


Q: How Do You Put A Zipper Back on Track?


To put the zipper back on track, simply cut a slit between the teeth on the zipper tape. The slit should be deep and open so that you will be able to insert the zipper slider. Next, simply slide the zipper slider all the way down.

Q: How Do You Fix A Zipper on A Bag?


How you fix a zipper on your bag will depend on the issue you are facing. For example, if the zipper is stuck because of a lack of lubrication, simply use graphite, wax, or laundry soap to lubricate the zipper. If the teeth are bent, straighten them with a pair of pliers. If the slider is broken, simply replace it.

Q: How Do You Fix A Zipper That Comes Off One Side?


To fix the zipper when the slider comes off on one side, simply move the slider all the way down, as far as you can get it. Just above the zipper, on the side where the slider came off, make a slit in between two zipper teeth. Slide the slider in and move it up. Above the slit you had cut, use a sewing needle and a thread to sew the closed zip together to keep the slider from coming off again.

Q: How Do You Fix A Broken Zipper Slider?


The best way to fix a broken zipper slider is to replace it. Simply remove the broken slider and slide a new slider into place. If you already have the new zipper slider nearby, this should take just a few minutes.
