How To Fix Broken Zipper on Backpack

A broken zipper can be a real inconvenience. Not only is it unsightly, but it can also make the item it’s attached to difficult to use. Here are a few tips on how to identify a broken zipper and what you can do about it.

Zippers come in all shapes and sizes, so the first step in identifying a broken zipper is to determine the type of zipper it is. There are four main types: coil zippers, metal zippers, plastic zippers, and invisible zippers.

Once you’ve determined the type of zipper, check to see if it’s opened all the way. If it’s not open all the way, try opening it manually. If it doesn’t open at all, then the slider (the part that moves up and down) is likely broken.

The causes of a broken zipper

There are many reasons a zipper might break. Some are more common than others. A broken zipper can be caused by a number of factors, including the following:

Poor quality zippers are more likely to malfunction. Cheap zippers tend to break more easily because they are made with low-quality materials and construction. If you’re looking for a durable zipper, invest in a quality brand.

Zipper teeth can become worn down over time, which can lead to them breaking or coming apart from the slider. Regularly checking your zippers for any signs of wear and tear can help prevent this from happening.

If a zipper is overloaded with too much weight or stress, it can snap or break. This is particularly common with heavy winter coats that have multiple layers and lots of zippers. Be careful not to overload your zippers if you want them to last longer.

How to fix a broken zipper on a backpack

A broken zipper can be a frustrating and common problem on backpacks. Luckily, there are a few ways to fix it. The easiest way is to use a key or a pen to move the slider up and down until it catches. If that doesn’t work, try using pliers to gently pull the slider up and down until it catches. If the teeth of the zipper are broken, you can try using a dental pick or a safety pin to hook the teeth and pull them back into place. Once the zipper is fixed, make sure to test it by zipping it up and down several times.

Tips for preventing a broken zipper on a backpack

One of the most common ways a backpack zipper breaks is when it is overloaded with too much weight. Putting too much weight on one side of the zipper can cause it to separate from the fabric. To prevent this, distribute the weight evenly by packing heavier items on the bottom and lighter items on top.

To keep the slider moving freely, apply a small amount of lubricant like sewing machine oil, graphite or beeswax to the teeth of the slider. You can also try using a toothbrush to get in between the teeth.

If the slider becomes stuck, try to free it by gently pushing down on one side while pulling up on the other side. If this doesn’t work, you may need to cut off the pull tab and reattach it using a small key ring or binder clip.


In conclusion, there are several ways to fix a broken zipper on a backpack. The best way to fix it will depend on the severity of the break. If the teeth of the zipper are missing, then a new zipper will need to be installed. If the slider is missing, then it can be replaced with a new one. If the slider is stuck, it can be loosened with a key or a toothpick. If the zipper is loose, then it can be tightened with pliers.
