Metal and plastic zippers have their own unique advantages and disadvantages. Metal zippers are generally considered to be stronger and more durable, especially for projects that may experience a lot of wear and tear, such as bags and jeans. They come in a variety of colours and metals, including nickel, brass, and aluminium. On the other hand, plastic zippers are strong and resistant to damage, making them suitable for outerwear. They are also lightweight, flexible, and resistant to corrosion. However, they may not be suitable for applications where the zipper needs to curve, as they are prone to pulling apart and separating while closed. Ultimately, the choice between metal and plastic zippers depends on the specific requirements of the project, the type of fabric being used, and the desired level of durability and ease of repair.

What You'll Learn
Metal zippers are stronger but plastic resists corrosion
Metal zippers are stronger than plastic zippers, but plastic resists corrosion. Metal zippers are typically used in jeans, skirts, and pants, while plastic zippers are used in projects with straight seams, such as outerwear. Metal zippers are made from materials such as nickel, brass, and aluminum, and have teeth that are clamped onto the zipper tape. Metal zippers are perfect for items that may experience a lot of wear and tear, like bags, outerwear, and pants. They are also heavier than plastic zippers and may not always be practical.
Plastic zippers, on the other hand, are made from molded plastic and are strong and resistant to damage. They are lightweight and suitable for flowy fabrics. However, they have a tendency to pull apart and separate while closed, making them less ideal for bags or luggage.
When it comes to repair, metal zippers are generally easier to fix. However, plastic zippers have their advantages, especially in marine environments, as they are not susceptible to rust or other elemental damage.
The choice between metal and plastic zippers ultimately depends on the specific requirements of the project. If strength and durability are the primary concerns, metal zippers are the better option. However, if corrosion resistance and lightweight properties are more important, plastic zippers may be preferred.
Additionally, the type of tooth on the zipper can also influence the decision. Metal zippers have individual teeth that are clamped onto the zipper tape, making them strong and durable. Plastic zippers, particularly coil zippers, have nylon teeth that are stitched to the zipper tape, making them lightweight and flexible but more prone to bending or damage over time.

Metal zippers are easier to repair
Metal zippers are generally easier to repair than plastic zippers. One of the most common zipper parts that needs repairing is the slider. The repair process is similar for both metal and plastic zippers. However, it is easier to remove a metal top stop with a pair of needle-nose pliers without damaging the tape than to break off a plastic one. Metal zippers are also easier to repair because, with metal teeth, it's much easier to make minor repairs thanks to pliers and the ability to gently squeeze or crimp the metal back into place.
On the other hand, if the teeth on a plastic zipper break or warp too much, it's not feasible to repair them, and replacement may be necessary. Plastic zippers are also more difficult to remove and replace because they are often made of iron. If you are attempting to repair a plastic zipper, you may need to substitute a broken piece with a few knots of thread or something similar.
Metal zippers are also more durable than plastic zippers. Metal zippers are perfect for items that might get a lot of wear and tear, such as bags, outerwear, and pants. They come in a large assortment of colours and different types of metals, including nickel, brass, and aluminium. Metal zippers are also heavier than plastic zippers and may not be practical for certain applications.
Plastic zippers have their advantages as well. They are strong and not subject to damage like coil zippers. They are great for outerwear but are not suitable for bags or luggage because they tend to pull apart and separate while closed. Plastic zippers are also lightweight and resistant to being pulled apart while closed, making them ideal for bags and luggage.

Plastic zippers are better for outdoor use
When it comes to outdoor applications, plastic zippers are the optimal choice. They are lightweight, strong, and weather-resistant. Plastic zippers are made from moulded plastic, making them highly durable and able to withstand harsh conditions. They are resistant to dirt, corrosion, and UV rays, ensuring smooth functionality over extended periods. This makes them ideal for outdoor gear, boat covers, and rugged luggage.
Plastic zippers are particularly well-suited for marine environments. They are resistant to saltwater damage and perform well in humid conditions, unlike metal zippers, which are susceptible to rust. Plastic zippers with polyester tape are excellent for marine applications as the polyester prevents moisture deterioration. Additionally, plastic zips are flexible and can withstand temperature fluctuations, making them suitable for extreme conditions.
While metal zippers are sturdy and repairable, they are not ideal for outdoor use, especially in saltwater or marine settings. Metal zippers are prone to corrosion and can corrode even when used indoors. They are more suitable for applications that do not encounter extended outdoor exposure, such as apparel, fashion, bags, backpacks, and upholstery.
The choice between plastic and metal zippers ultimately depends on the specific requirements of the project. If you require a zipper that can withstand the elements and perform well in outdoor conditions, plastic zippers are the better option. They are low-maintenance and will maintain their functionality through years of exposure to the elements.
However, it is important to consider other factors such as cost, aesthetics, and functionality when selecting a zipper. While plastic zippers offer superior durability and weather resistance, metal zippers may be preferred for their ease of repair and style. Nonetheless, for outdoor gear and applications, plastic zippers are the preferred choice due to their ability to withstand the rigours of outdoor use.

Metal zippers are more durable
Metal zippers are stronger and will last longer than plastic zippers. Metal zippers are also heavier than plastic zippers, and there may be applications where they are impractical due to their weight. Metal zippers are also more flexible than plastic zippers.
Plastic zippers are strong and suitable for outerwear. However, they have a tendency to pull apart and separate while closed, making them a poor choice for bags or luggage. Plastic zippers are lightweight and resistant to corrosion, which is ideal for marine environments. They are also easy to work with and sew over.
When choosing between a metal and a plastic zipper, it is important to consider the application. Metal zippers are best for items that require durability and strength, while plastic zippers are better for lightweight applications and resistance to corrosion.

Metal zippers are heavier
Metal zippers are commonly used on jeans and come in nickel, brass, and aluminum. They are also available in both open and closed bottoms, with common lengths ranging from 3 to 36 inches. Metal zippers are perfect for projects that might get a lot of wear and tear, such as bags, outerwear, and pants. They come in a large assortment of colors and different types of metals, providing a wide range of options for various projects.
Metal zippers are typically heavier than plastic zippers due to the nature of the materials used. Metal zippers have teeth made of metal, while plastic zippers have teeth made from molded plastic, which is a lighter material. The weight difference becomes more pronounced when comparing longer zippers, as the additional metal teeth contribute significantly to the overall weight.
While metal zippers offer superior strength and durability, their weight can be a disadvantage in certain situations. For projects that require lightweight materials or where weight is a critical factor, metal zippers might not be the ideal choice. In such cases, plastic zippers or other lightweight alternatives, such as coil zippers, may be more suitable options.
It's important to consider the weight of metal zippers when selecting them for specific applications. While they excel in providing strength and longevity, their weight can impact the overall weight of the final product. This consideration is particularly relevant for projects where weight distribution and overall weight are crucial factors, such as in the design of luggage, bags, or certain types of clothing.
