Different Types Of Backpack Zippers

There are actually a few different kinds of zippers on the market when it comes to keeping your backpack secure:

The molded (Plastic) Zippers

These zippers are made of distinct molded teeth that are made of Polyacetal resins and polyethylene that are durable. A zipper of this type is commonly found in backpacks for hiking, camping, and other high-performance activities. One of the main disadvantages of molded zippers is that they require replacement when even just one tooth is damaged.

Coil Zippers

It is made of polyester and has the best flexibility when zipping. In addition to being affordable and easy to use, coil zippers come in a range of colors and styles. These zippers need regular cleaning, however, as they tend to get dirty quickly.

Metal Zippers

The original design for metal zippers dates from the 1800s when zippers were first developed. At first, these zippers are solid, but they will rust and corrode over time and are heavier than the coil and molded zippers.

In this article, we discuss some of our top recommendations for making your zipper work again:

Include lubricants in your zipper’s teeth

Sometimes, the teeth of your backpack might need a little assistance from lubricants so that they can work again. Anything that contains chapsticks, crayon wax or petroleum jelly can be used. But, be careful to use them in a moderate manner and make sure that the material you choose to use doesn’t ruin your backpack or zipper.

Do not use your teeth for plier

It’s normal to feel frustrated feeling if the zipper of your backpack was ripped off on one side. But, there’s no reason to utilize your teeth as pliers while closing or closing the zippers. In fact, the use of your teeth is an easy way to harm your sliders to the point of irreparable damage.

Use masking tape to help you thread your zipper from the bottom

The process of aligning tracks and threading zippers could be difficult if you are unsure of your hands or your zipper fell from the direction of travel. Masking tape may assist in making the process simpler by allowing a smoother space for the slider to slide before it is able to reach the teeth.

Make small, equal strips of tape all around the tracks on your backpack. Be sure to leave sufficient space between them. This will allow you to easily slide the slider on the backpack.

How To Fix A Stuck Zipper On A Backpack

A zipper that is stuck in your backpack is likely to be the most frequent problem you’ll have to deal with. In most cases, it’s due to the zipper becoming filthy or clogged up. To resolve the issue is usually as easy as cleaning, or even lubricating your zipper’s teeth and zipper.

To grease, the zipper begins with a little washing detergent as well as warm water. After that, dip in a cotton swab mixture and wipe it clean across the entire line of zippers.
