Zipper tape is the fabric strip that forms the backbone of a zipper. It is typically made from materials like polyester or nylon and serves as the base to which the zipper teeth are attached. The tape comes in various widths and colors, allowing for customization in different applications, from clothing to bags. The zipper teeth, which can be made from metal or plastic, are sewn onto the zipper tape to create a functional closure. When the zipper pull is moved, the teeth interlock or separate, allowing for easy opening and closing. This simple yet effective design is widely used in everyday items.
