What Are the Three Types of Zippers?

Ever struggled with a stuck zipper or wondered why some zippers feel smoother than others? Zippers might seem like a simple invention, but there’s more variety than most people realize. So, what are the three main types of zippers?

The three main types of zippers are coil zippers¹, metal zippers², and molded plastic zippers³. Each type has unique characteristics that affect durability, flexibility, and appearance.

Let’s explore these zipper types, their uses, and how to choose the right one for your needs.

What are coil zippers, and when are they used?

Coil zippers are among the most common types, especially in garments and bags.

Coil zippers, also called nylon zippers, use interlocking coils made from nylon or polyester. They offer flexibility, durability, and smooth operation.

How do coil zippers work?

Coil zippers use a spiral coil that runs along each side of the zipper tape. When zipped, the interlocking coils form a secure closure.

• Material: Nylon or polyester.
• Construction: Spiral coil stitched to zipper tape.
• Teeth shape: Rounded and flexible.

Why are coil zippers so popular?

Feature	Performance
Flexibility	High – bends easily around curves.
Durability	Moderate – resists abrasion but can snag.
Weight	Lightweight – suitable for apparel.
Cost	Affordable – mass-produced and widely available.

Applications:

• Jackets and hoodies.
• Backpacks and luggage.
• Dresses and skirts.
• Tents and sleeping bags.

Coil zipper pros and cons

Pros:

• Lightweight and flexible.
• Available in various sizes and colors.
• Smooth, snag-resistant operation.

Cons:

• Less durable than metal or molded zippers.
• Coils can distort under heavy load.

Pro tip: Choose coil zippers for curved seams or garments requiring lightweight, flexible closures.

What makes metal zippers a classic choice?

Metal zippers are the oldest and most recognizable type, commonly found in jeans and leather jackets.

Metal zippers have interlocking metal teeth made from materials like brass, aluminum, or nickel. They are strong, durable, and stylish.

How do metal zippers differ from other types?

Unlike flexible coil zippers, metal zippers use individual metal teeth attached to a sturdy tape.

• Material: Brass, aluminum, nickel, or stainless steel.
• Construction: Individual metal teeth crimped onto tape.
• Teeth shape: Angular and rigid.

Types of metal zipper finishes

Metal Type	Appearance	Durability	Common Use
Brass	Gold-toned, polished	High	Denim, workwear
Aluminum	Silver, lightweight	Moderate	Lightweight jackets
Nickel	Shiny, cool-toned	High	Leather jackets, bags
Antique brass	Aged, rustic finish	High	Vintage clothing

Where are metal zippers used?

• Denim jeans and jackets.
• Leather jackets and boots.
• Workwear and outdoor gear.
• High-end bags and accessories.

Metal zipper pros and cons

Pros:

• Extremely durable.
• Stylish, classic appearance.
• Ideal for heavy-duty applications.

Cons:

• Heavier than plastic or coil zippers.
• Can corrode if exposed to moisture.

Maintenance tip: Apply a small amount of lubricant (e.g., beeswax) to keep metal zippers moving smoothly.

What are molded plastic zippers, and why are they popular?

Molded plastic zippers are a modern, versatile option found in various garments and accessories.

Molded plastic zippers feature teeth made from injection-molded plastic. They are lightweight, weather-resistant, and available in vibrant colors.

How are molded plastic zippers constructed?

Plastic zippers use individually molded teeth that snap together securely.

• Material: Polyacetal (POM) or polyethylene.
• Construction: Injection-molded teeth fused to zipper tape.
• Teeth shape: Blocky and uniform.

Why are molded plastic zippers so versatile?

Feature	Performance
Durability	Moderate – resistant to corrosion but less strong than metal.
Water resistance	High – plastic teeth don’t rust.
Flexibility	Moderate – less flexible than coil zippers.
Cost	Low – inexpensive to manufacture.

Common uses for molded plastic zippers

• Raincoats and outdoor jackets.
• Children’s clothing.
• Backpacks and sports bags.
• Waterproof applications (e.g., marine gear).

Molded plastic zipper pros and cons

Pros:

• Lightweight and rust-resistant.
• Available in bright colors and shapes.
• Affordable and easy to produce.

Cons:

• Prone to breaking under excessive stress.
• Less flexible compared to coil zippers.

Design tip: Use molded plastic zippers for waterproof clothing and colorful designs.

How do these zipper types compare in performance?

Now that we know the basics, how do coil, metal, and molded plastic zippers perform in everyday situations?

The best zipper type depends on the garment’s purpose. Coil zippers suit flexible apparel, metal zippers provide strength, and molded plastic zippers excel in weatherproof applications.

Performance comparison

Attribute	Coil Zipper	Metal Zipper	Plastic Zipper
Flexibility	High	Low	Moderate
Durability	Moderate	High	Moderate
Weight	Light	Heavy	Light
Weather Resistance	Moderate	Low (can corrode)	High
Aesthetic Appeal	Basic	Classic	Colorful
Cost	Low	High	Low

Key takeaways

• Choose coil zippers for curved or flexible garments like activewear.
• Choose metal zippers for jeans, leather jackets, or items needing durability.
• Choose molded plastic zippers for weather-resistant or colorful items.

Pro tip: For high-quality hoodies, metal or coil zippers often provide the best long-term performance.

What specialty zipper types exist beyond the main three?

Beyond coil, metal, and molded plastic, the zipper world offers specialized options.

Specialty zippers cater to specific needs, like waterproofing, reversibility, or increased durability.

Popular specialty zippers

Zipper Type	Key Feature	Common Applications
Invisible Zipper	Concealed teeth	Dresses, skirts, pillows
Waterproof Zipper	Sealed seams	Raincoats, tents
Reversible Zipper	Two-way operation	Jackets, bags
Two-Way Zipper	Opens from top/bottom	Long coats, luggage

Example: A reversible zipper on a jacket allows you to flip the garment inside-out without losing functionality.

How to identify high-quality specialty zippers

• Smooth operation: No catching or sticking.
• Durable tape: Should resist fraying or stretching.
• Consistent teeth alignment: Misaligned teeth cause jams and breaks.

Tip: When buying custom apparel like hoodies, always test the zipper multiple times to ensure smooth operation.

How do you choose the right zipper for your hoodie?

Zippers might seem like a minor detail, but they impact both function and aesthetics.

To choose the right zipper, consider the garment’s purpose, required durability, and desired appearance.
