It is suitable for ordinary bags. One-way closed-end zipper refers to a closed-end zipper with a slider. The two-way closed-end zipper refers to a closed-end zipper with two sliders. And the two sliders can be opened and closed facing away or facing each other.

The composition of the zipper
The zipper is composed of chain teeth, sliders, zipper chains, back & forth head tape, zipper puller, pin, or locking parts. The chain teeth are the key part, which directly determines the side pull strength of the zipper. Generally, a zipper has two chain belts, and each chain belt has a row of chain teeth. And the two rows of chain teeth are arranged in a staggered manner. The slider clamps the chain teeth on both sides. With the help of the pull tab, the chain teeth on both sides can be engaged or disengaged.
History of zipper’s Invention
The zipper is one of the top ten inventions that facilitate people’s lives in modern times. The zipper appeared a century ago. At that time, in some places in Central Europe, people tried to replace buttons and bows with belts, hooks, and loops. So they began to experiment with the development of zippers. Zippers were first used in military uniforms.
In World War I, the US Army ordered many zippers for soldiers to make clothing for the first time. However, the promotion of zippers in the private sector was relatively late. And it was not accepted by women until 1930 as a substitute for buttons in clothing.
