How to Fix a Broken Zipper on a Lunch Box: A Step-by-Step Guide

In the hustle and bustle of daily life, a lunch box is a handy companion. But what do you do when the zipper on your trusty lunch box breaks? Before you decide to discard it, consider fixing the zipper yourself. Here’s a step-by-step guide to help you restore your lunch box to its former glory.

Step 1: Assess the Damage

Before you start, take a moment to assess the extent of the damage. Determine whether the zipper is completely broken or if it’s just stuck.

Step 2: Gather Necessary Tools

To fix the zipper, you will need a few tools and supplies:

  • A pair of needle-nose pliers
  • A small screwdriver
  • A zipper repair kit (available online or at sewing stores)
  • A seam ripper (if necessary)

Step 3: Remove the Old Zipper

If the zipper is beyond repair, use the seam ripper to carefully remove the old zipper from the lunch box. Be sure to remove any threads or debris that might be caught in the zipper’s path.

Step 4: Prepare the New Zipper

Take the new zipper from the repair kit and prepare it for installation. If it’s a separate piece, you might need to insert the zipper pull onto the zipper chain.

Step 5: Install the New Zipper

Align the new zipper onto the lunch box, ensuring that it is straight and even. Start sewing the zipper onto the lunch box, either by hand or using a sewing machine. Make sure to secure the ends well to prevent fraying.

Step 6: Test the Zipper

Once the new zipper is installed, test it several times to ensure that it is functioning correctly. If necessary, make adjustments to ensure a smooth zip.

Step 7: Final Touches

After confirming that the zipper works perfectly, cut off any excess zipper tape and finish off the ends neatly to prevent fraying in the future.


Fixing a broken zipper on a lunch box is a simple yet satisfying DIY project. Not only does it save you money, but it also allows you to extend the life of your lunch box. So, the next time you find yourself with a broken zipper, don’t throw away your lunch box. Instead, roll up your sleeves and fix it yourself with this handy guide.

Remember, a well-maintained lunch box can serve you for many years, helping you carry your meals safely and conveniently. Happy fixing!
