A zipper is a common closure mechanism used in backpacks, and it can be frustrating when it breaks. Fortunately, fixing a zipper on a backpack is relatively easy and can be done in a few simple steps.
First, you will need to identify the type of zipper that is on your backpack. There are two main types of zippers: coil zippers and chain link zippers. Coil zippers are made of a continuous coil of plastic or metal, while chain link zippers are made of a series of interlocking metal links. Once you have identified the type of zipper, you can begin the repair process.
