Most of the time we face the problem that the zip of the backpack gets stuck and won’t zip, whether it is a new backpack or an old one.

This could be happened due to many reasons such as :

  • When we overload the backpack, this causes stress in the zip.
  • The second reason is the zipper slider area becomes dry and requires some kind of lubrication.  
  • The third reason is the zipper molds may have become loose.

In this article, we’ll discuss some ways that are simple and effective. 

So let’s figure it out…

  • Use Some kind Of Lubricant

Sometimes the reason behind the zipper becoming stuck is that the zipper area becomes dry and due to the absence of lubrication, it becomes hard to move the zipper smoothly on the slider.

In this situation, you can use some lubricants like any kind of oil like car engine oil, hair oil, etc. This will make the zipper area slippery and help the zipper slide.

Let’s make it more simple, you can also use a pencil to lubricate the zipper area.

Pencils are made using graphite. Graphite is a good solid lubricant and is used to lubricate railway track joints, air compressors, the food industry, etc.

  • Use A Plier To Press the Zipper Groove Lightly 

In most cases, the zipper holder becomes loose and unable to make a proper grip with the zipper, in that case, the zip won’t close properly. 

This type of problem can be solved very easily by using a plier. simply take the plier close to the zipper socket and press the zipper area lightly. 

Keep in mind that one should not put too much pressure here!

In this way, the loose zipper socket will be tightened and the zip will slide in a proper way.
