Tools You’ll Need

Before moving to the tutorials on how to fix a zipper on a backpack, let’s talk about what you will need to get started.

Having the right tools at your disposal can make all the difference. Fortunately, you won't need an extensive toolkit for the following tutorials. A few simple tools can work wonders in restoring your zipper to its former glory. Below is a brief rundown of the essential tools you'll need to fix a broken zipper on a backpack:

  • Needle-nose Pliers
  • Scissors
  • Zipper Lubricant
  • Wax or Soap
  • Replacement Zipper Slider
  • Sewing Kit
  • Safety Pins.

Needle-nose Pliers

These slender, pointy pliers are a zipper's best friend. Their features make them incredibly easy to grip and manipulate the zipper slider, especially when trying to realign misaligned teeth.

Scissors

A pair of sharp scissors is great for trimming any frayed threads or excess fabric around the zipper area or any excess thread in your daily clothes. Precision is key for fixing a zipper on a backpack, so opt for scissors with a fine tip. 

Zipper Lubricant

If you’re here to fix your favourite backpack for good, consider investing in a zipper lubricant. This product can prevent future issues by keeping the zipper teeth moving smoothly. Or, if you can’t find this zipper lubricant, then having Wax or Soap is an alternate option.

Wax or Soap

A small amount of wax or soap applied to zipper teeth can work wonders in lubricating a stubborn zipper. As you do this, it will ease friction and ensure smooth zipping and sliding.

Replacement Zipper Slider

In some cases, the zipper slider may be completely damaged, which requires you to have a replacement slider of the appropriate size. So, make sure to measure out your zipper size to buy the correct one for your backpack.

Sewing Kit

A basic sewing kit with assorted needles and thread in matching colours will be useful for stitching up any loose seams or reattaching a zipper that has come undone from the fabric. A sewing kit is usually a staple household item, so it might already be in your possession.

Safety Pins

Safety pin is another household stable that can serve as temporary fixes for a separated zipper, holding it in place until you can implement a more permanent solution. One can easily find these tools in the nearby grocery store or supermarket, or just look for one in your house.

How Do You Fix A Zipper That Separates On A Backpack?

To tackle a zipper separation issue on a backpack, you can take the following steps:

  1. Examine Zipper Alignment
  2. Apply Lubrication
  3. Adjust The Slider 
  4. Replace The Sliders
  5. Check The Stops

Examine Zipper Alignment

Begin by scrutinising the alignment of the zipper tracks. If you see any misalignment, gently use your hand to realign the tracks, ensuring the teeth engage smoothly. Thoroughly inspect the zipper for any impediments, such as fabric or debris. Eliminate such obstructions using a small brush or compressed air to restore unimpeded movement. 

Apply Lubrication

Apply a modest amount of zipper lubricant, wax, or soap, whichever you can have your hands on, on the zipper teeth to help smoothen the zipping movement. 

Adjust The Slider

Assess the tightness of the slider – the component moving along the zipper teeth. If it feels excessively loose, gently use pliers to tighten it. Be very careful not to push too much pressure on this step to prevent undue pressure that may lead to damage. 

Replace The Slider

If the slider is too damaged to recover or unresponsive to tighten, you can consider replacing the slider with an alternative. For this, ensure you get the correct slider size for your backpack. Remove the old slider with pliers and attach the new one by sliding it onto the teeth in the same orientation. 

Check The Stops

Ensure the zipper stops, situated at both ends, are secure. If loose, use pliers to reaffix them. If it is too damaged, you may have to replace the entire thing.

How Do You Fix A Stuck Zipper On A Backpack?

  1. Assess the Cause of Obstruction
  2. Gently Realign the Zipper Tracks
  3. Lubricate the Zipper
  4. Gradual Movement
  5. Use Pliers
  6. Avoid Yanking or Forcing
  7. Inspect for Damage

Assess the Cause of Obstruction

Firstly, identify the source of the zipper obstruction. This may include fabric folds, debris, or misalignment of the zipper teeth. 

Gently Realign the Zipper Tracks

If you find any misalignment, delicately realign the zipper tracks with your fingers. Ensure that the teeth zip smoothly. Thoroughly inspect the zipper for any accumulated debris. Use a small brush or compressed air to remove any obstructions that create unimpeded movement gently.

Lubricate the Zipper

Apply a small amount of zipper lubricant, wax, or a dry bar of soap to the zipper teeth. The lubricant aids in reducing friction and easing the movement of the zipper slider. 

Do It Slowly

Make sure the zipper slider moves gradually along the tracks, exerting even and controlled pressure. Avoid excessive force, as this may exacerbate the issue.

Use Pliers for Gentle Assistance

If the zipper remains stuck, cautiously employ pliers to move the slider. Exercise caution to avoid causing damage to the zipper or surrounding fabric. 

Avoid Yanking or Forcing

Refrain from forcefully yanking or tugging on the zipper, which can lead to more damage. Patience and gentle manipulation are vital in resolving a stuck zipper. 

Inspect for Damage

After successfully freeing the zipper, inspect for any signs of damage, such as bent teeth or a misshapen slider. Address any identified issues promptly to prevent recurrence.

How To Take Care Of A Backpack Zipper

Prevention is better than cure, and it also applies to your backpack's well-being. To avoid the catastrophe of trying to fix a zipper on a backpack, please refer to our suggestions.

Apply Lubrication Regularly

Lubricating the zipper is something you should do regularly. Your zippers may get stuck due to debris, dirt, or simple wear. Ideally, this step should be done after washing or cleaning your backpack. If fully washing and cleaning your backpack is too much of a hassle, use a damp cloth to wipe all of the dirt every now and then.

Handle with care, and your backpack’s zipper will last.

Deep Clean Occasionally

For a deeper clean, you can mix mild dish soap with water and use a soft sponge to scrub the zipper teeth gently. Rinse thoroughly with clean water and let it air dry completely before using. The steps are pretty much the same as deep cleaning your whole backpack. Remember to get the zippers completely open to avoid getting soap suds stuck inside.

Be Careful With Sharp Objects

It’s a cardinal rule to leave anything sharp far away from your backpack, be it knives or scissors. Even those pens, keys, and multi-tools are no exception (thankfully, loop pens, key clips, and dedicated pockets are there to help). You should also pack softer items closest to the zipper to cushion any accidental pokes.

Avoid Overloading Your Backpack

If possible, please refrain from overloading your backpack, as excessive weight can put extra strain on not just your zipper but on your backpack fabric and handle as well. Distributing your belongings evenly would help resolve this problem. 

Close And Open The Zipper Gently

Sometimes, when you’re in a rush, you can involuntarily zip and unzip your backpack in an aggressive manner. This habit can wear down your zipper health in the long run, so try to use slow and steady movement when using your zipper. Also, refrain from forcing the zipper when it’s stuck.

Inspect Your Zipper Regularly

Give your zipper a quick look-over before every adventure. Check for snags, loose threads, or damage that could lead to sharp surprises. A vigilant eye and mindful packing can go a long way in protecting your precious zipper.
