What is resin zipper？

A resin zipper, often also called a plastic zipper or molded plastic zipper, is a type of zipper where the teeth are made from plastic material, typically polyester resin.

Here's a breakdown of what that means:

• Material: The key characteristic is that the interlocking teeth are made from a plastic (resin) material. This differs from metal zippers (which have metal teeth) and nylon coil zippers (which have a spiral coil of nylon filament as their teeth).

• Manufacturing Process: Resin zippers are produced through an injection molding process. Molten polyester plastic is injected into specific molds, which form the individual zipper teeth directly onto the fabric tape. This allows for precise and consistent teeth formation.

• Characteristics:

  • Lightweight: Generally lighter than metal zippers of the same size.

  • Durable and Tough: Resin zippers are known for their strength, abrasion resistance, and corrosion resistance

  • Versatile in Color and Design: Because they are molded from plastic, they can be easily dyed in a wide range of colors to match or contrast with the fabric. The molding process also allows for variations in the shape and size of the teeth, offering more design possibilities than other zipper types. Some can even have decorative elements like metallic finishes or glow-in-the-dark properties.

  • Wide Temperature Range: They are suitable for a broad range of temperatures.

  • Feel: Due to the often larger and more defined teeth, they can have a slightly "rougher" feel compared to the smoother glide of a nylon coil zipper.

• Common Applications: Resin zippers are widely used in:

  • Thick fabric clothing (jackets, coats)

  • Outerwear (ski shirts, down jackets)

  • Children's clothes

  • Work clothes

  • Luggage and bags

  • Sportswear

In summary, a resin zipper is a popular and versatile type of zipper characterized by its molded plastic teeth, offering durability, lightweight properties, and a wide array of aesthetic options.
