Zippers are everywhere in life. Clothes, shoes and bags can all have zippers, which is very convenient. However, zippers can also break. Let’s see how to repair a broken zipper on a bag and learn some life tips.

How to repair a broken zipper

Most of the broken zippers are caused by loose locks. Therefore, when a zipper breaks, first check to see if the lock is loose. If so, just use pliers or something like that to press the lock down. It is not recommended to use your hands, on the one hand because it requires a lot of force, and on the other hand to avoid injury.

If it is not a problem with the lock, but a problem with the lock not getting stuck, that is to say, even if the zipper is fully closed, it will fall off after a while, which means that the lock is not getting stuck. In this case, you will need to go to a clothes repair place to replace a new lock.

Another common problem is that one or more of the zipper's teeth have fallen off. It is quite troublesome to zip it up at this time. It is also very troublesome to repair it yourself. Generally, you need to go to a tailor shop to get a batch of new zippers. Of course, if you think going to a tailor shop is too expensive, you can also buy a batch of new zippers yourself and sew them at home.

Most of the bags nowadays are equipped with metal zippers, especially some bags with a stronger punk flavor. For bags with metal zippers, this metallic texture also adds a lot of points to the bag. What should you do if the zipper of this bag is broken? Don’t worry, there are many useful methods provided. Keep reading. Some small bags have plastic zippers. One advantage of plastic zippers is that they are very smooth when pulled and will not get stuck as easily as metal zippers. So what should I do if the zipper of this bag is broken? What is the solution?

1. Metal zipper

Generally speaking, a broken metal zipper is easier to repair. For example, if the zipper of a leather bag is opened, you can reinstall the zipper from the top. If there is still a problem, use a pair of pliers to clamp the two sides of the zipper together with a little force. This method is suitable for one or two uses. If you use it too many times, the zipper will directly become dislocated, and you will have to replace it with a new one.

2. Plastic zipper

The solution to a broken plastic zipper is to put a few drops of lubricant on the zipper, or regular oil will do. We know that oil has a lubricating effect. If the zipper teeth are not broken, it may be because the zipper has too much friction before. Of course, if you find French oil dripping and greasy too much, you can also use candles. Spread the candle evenly on the zipper and zip it up again.

We often see that some zippers have been worn for a long time, and the thread fixing the teeth has broken, causing the teeth to separate from the cloth base, making it inconvenient to open and close, and not elegant to wear. For those that are not seriously damaged, we do not recommend replacing the zipper, but just repair it. Use a 30-35mm fine needle to thread a double strand of nylon thread, and re-fix the teeth to the cloth base one by one. Note that the needle and thread should follow the direction of the teeth, and sew more at both ends to ensure that they will not separate, wax, and pull evenly.
