How to Fix a Zipper Backpack

Tips and Tricks – Backpacks are one of the most convenient accessories for everyday use. They are used by people of all ages, and they come in different shapes, sizes, and designs. However, one of the most common problems with backpacks is a broken or stuck zipper. A broken or stuck zipper can be frustrating and can make it difficult to access the contents of your backpack. 

In this article, we will provide you with step-by-step instructions on how to fix a zipper backpack.

Tools You Will Need

Before you start fixing your zipper backpack, you will need to gather the following tools:

  • Needle-nose pliers
  • Zipper lubricant (e.g. WD-40)
  • Scissors
  • Thread and needle

Steps to Fix a Zipper Backpack

Step 1: Identify the Problem

The first step in fixing a zipper backpack is to identify the problem. Is the zipper stuck? Is it broken? Is the slider missing? Once you have identified the problem, you can proceed to the next step.

Step 2: Remove the Zipper Slider

If the zipper slider is missing, you will need to remove the zipper stops using the needle-nose pliers. Once the stops are removed, you can pull the zipper tape apart and remove the slider. If the slider is not missing, you can skip this step and proceed to the next step.

Step 3: Lubricate the Zipper

If the zipper is stuck, you can use a zipper lubricant like WD-40 to loosen it. Spray the lubricant on both sides of the zipper and try to move the slider up and down. If the zipper still does not move, you can use the needle-nose pliers to gently pull the zipper teeth apart.

Step 4: Replace the Zipper Slider

If the slider is broken, you will need to replace it. Cut off the old slider using the scissors and slide the new slider onto the zipper tape. Make sure the new slider is facing the right direction before you zip up the backpack.

Step 5: Sew the Zipper Stops

If you had to remove the zipper stops in step 2, you will need to sew them back on using the needle and thread. Make sure the zipper stops are aligned with the teeth of the zipper tape before you start sewing.

Tips for Preventing Zipper Problems

Prevention is always better than cure. Here are some tips to prevent zipper problems:

  • Avoid overloading your backpack.
  • Always zip up your backpack carefully.
  • Keep the zipper lubricated with a zipper lubricant.
  • Do not force the zipper if it is stuck.

However, it is important to take preventive measures to avoid zipper problems in the future. Follow the tips we have provided and your backpack zipper will last longer.
