Occasionally zippers may get stuck, jammed or simply come off the slider.  Before we get into how to fix a zipper on a backpack Let’s quick review the 4 most common types of zippers. These include nylon coil zippers, plastic molded zippers, metal zippers and invisible zippers.

Here is a summary of the different types of zippers:

Nylon Coil Zippers: The most common type of zipper and made of nylon thread that is twisted into a coil. Nylon coil zippers are strong and durable, and they are also relatively inexpensive. They are a good choice for most applications, but they are not the best choice for heavy-duty use.

Plastic Molded Zippers: Made of a plastic that is molded into the shape of the teeth. Plastic molded zippers are less expensive than nylon coil zippers. These zippers are not as strong or durable so if you are trying to fix a zipper on a backpack, it may not be possible if the teeth are broke. They are a good choice for lightweight applications, but they should not be used for heavy-duty use.

Metal Zippers: Made of metal that is stamped into the shape of the teeth. Metal zippers are the strongest and most durable type of zipper. They are a good choice for heavy-duty applications, such as jackets, coats and men’s tactical backpacks. However, metal zippers are also the most expensive type of zipper.

Invisible Zippers: Made with the teeth hidden inside the fabric. Invisible zippers are a good choice for garments where the zipper is not supposed to be seen, such as dresses and skirts. However, invisible zippers are more difficult to sew than other types of zippers.

Steps to Fix a Zipper on a Backpack

This method involves reattaching the zipper slider. In many cases it is relative easy but following the steps below to help resolve the issue.

  1. Locate the zipper slider. This is the small plastic or metal piece that fits over the teeth of the zipper.
  2. If the zipper slider is off one side of the zipper, gently pull it back onto the teeth.
  3. If the zipper slider is stuck, you can try using a lubricant, such as a pencil eraser or a bit of soap. Rub the lubricant onto the teeth of the zipper and then try to move the slider.
  4. If the zipper slider is still stuck, you may need to replace it. To do this, you will need to purchase a new zipper slider that is the same size as the old one.

If the zipper is stuck, it may be because something is caught in the teeth. Try to gently pull out any fabric or other objects that may be caught. A dry lubricant, such as graphite from a pencil, can help to smooth out the teeth and make the zipper slide more easily.

Rub the graphite on the teeth closest to the slider. If the zipper is off track, you can try realigning the teeth manually. Use a pair of pliers to gently pull the teeth back into place. If the slider is broken, you can replace it with a new one. To do this, first remove the old slider using a pair of pliers. Then, slide the new slider onto the zipper teeth. If you’ve tried all of these tips and the zipper is still not working, you may need to take it to a tailor. A tailor will be able to repair or replace the zipper for you.

Additional Tips on Fixing a Zipper on a Backpack:

  • If the zipper is only slightly damaged, you may be able to fix it by simply lubricating the teeth.
  • If the zipper is completely broken, you will need to replace it.
  • When replacing the zipper, make sure that you purchase a zipper that is the same size and type as the old one.

With proper care, your backpack should last for many years. Hope this helps and happy backpacking.
