By knowing the material of the zipper teeth, we can make better decisions when choosing a zipper. We have shared knowledge about nylon coil zipper before, today we continue to learn Metal Zipper and Plastic Zipper,

1. Metal Zippers

The most common metals used to make zippers are aluminum, gunmetal, nickel, antique nickel, and brass. Metal zippers often appear on on handbags, overalls, and as mentioned, denim and jeans, and it complements the overall look of the garment. Especially jeans, it is almost completely characterized by a larger size metal zipper. Some metal zippers are specially treated to produce a smooth, shiny surface, hence the name luxury zippers.

The characteristics of metal zipper are:

Because it uses metals as raw materials, it is less flexible.

Very durable, but cannot withstand horizontal stretches as plastic and coiled zippers can.

The teeth rarely break off, but when it does the zipper can only be permanently fixed by replacing it completely. For a temporary fix, one can sew through the broken tooth to make the zipper shorter.

2. Plastic Molded Zippers

Due to its various colors, plastic zippers are often used in clothing and handbags to make things look more beautiful. The teeth / elements of this zipper are made of a high-performance resin, such as an acetal polymer, which are individually extruded, molded, and injected onto tape.

The characteristics of plastic zipper are:

This type of zipper has a relatively high durability and flexibility.

Molded perfectly symmetrical on both sides. Like the nylon coil zipper, the slider can be attached on both ends.

Easy to be dyed and colored, allowing matching color with the garment.

When one of the teeth breaks, the zipper cannot be used normally, and it is almost difficult to repair. In most cases, only a new zipper can be replaced.
