What is sac zipper?

A sac zipper (also known as a drawstring zipper or cinch zipper) is a type of zipper that is commonly used on bags and backpacks. It consists of two fabric tapes or cords that are attached to the sides of the bag's opening, and a slider or pull that connects the cords to open and close the bag.

The name "sac" comes from the French word for bag, and this type of zipper is often used on bags that have a soft and flexible shape, like gym bags, duffel bags, and luggage. Sac zippers are designed to be quick and easy to open and close, and they provide a secure closure that helps keep items inside the bag from falling out.

One advantage of sac zippers is that they do not have separate teeth like traditional zippers, so they are less likely to break or get stuck. They are also lightweight and flexible, which makes them ideal for use on bags that need to be carried or worn on the body.

Sac zippers can be made from a variety of materials, including nylon, polyester, and cotton. They come in different sizes and colors to match the style and function of the bag they are used on. Some sac zippers also have additional features like locking mechanisms or reflective strips for increased visibility.
