How to choose a zipper?

Reasonable and correct use of zippers is an important way to improve the service life of zippers. Reasonable use includes two meanings.

Therefore, when selecting zippers, the manufacturer must pay attention to the following problem.

The structure and composition of the zipper

A zipper is a fastener made up of two belts with a row of metal teeth or plastic teeth. It is used to connect the edges of the opening (such as clothes or bag openings). A zipper sliding piece can pull the two rows of teeth into the interlocking position to make the opening closed.

The zipper is composed of chain teeth, sliders, and locking parts. The zipper 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 alternately. The slider clamps the chain teeth on both sides and slides with the help of the pull tabs to make the chain teeth on both sides engage or disengage each other.
