Nylon Coil Zips: A Comprehensive Guide for Bag Making

When it comes to bag making, choosing the right materials is essential. Among these, nylon coil zips are a popular and versatile choice, offering durability, flexibility, and style. Whether you are an experienced bag maker or a beginner, understanding the characteristics, benefits, and uses of nylon coil zips can elevate your projects to the next level.

This article delves deep into the features, types, and tips for using nylon coil zips in bag making, ensuring your creations are not only functional but also visually appealing.

What Are Nylon Coil Zips?

Nylon coil zips, often referred to as nylon zippers, are a type of zipper with teeth made from coiled nylon filament. Unlike metal or moulded plastic zippers, the teeth of nylon coil zips are flexible and lightweight, making them ideal for applications requiring smooth operation and adaptability.

Key Characteristics of Nylon Coil Zips

• Durability: The coiled nylon teeth are resistant to wear and tear, making them perfect for daily-use bags.
• Flexibility: Their soft and pliable design ensures they can curve seamlessly, suitable for designs with rounded edges.
• Variety of Sizes: Available in a range of widths, from delicate #3 zippers for small pouches to sturdy #5 and #10 zippers for heavy-duty bags.
• Colour Options: Nylon coil zips come in a spectrum of colours, allowing for perfect coordination with fabrics.
• Ease of Use: They are easy to sew into projects, whether by hand or machine.

Why Nylon Coil Zips Are Perfect for Bag Making

Versatility in Design

Nylon coil zips can adapt to various bag styles, from compact clutches to large travel duffels. Their flexibility makes them an excellent choice for:

• Backpacks: Offering durability to withstand heavy loads.
• Handbags and Totes: Adding a sleek, professional finish.
• Cosmetic and Toiletry Bags: Resistant to moisture, ensuring contents stay protected.
• Laptop Sleeves: Providing a secure yet smooth closure.

Durability for Everyday Use

Bags often endure significant strain, especially at the zipper area. Nylon coil zips are designed to handle frequent usage without compromising functionality. Their robust coil teeth can withstand pulling and tugging, ensuring longevity.

Aesthetic Appeal

With the ability to match zippers to fabric or thread, nylon coil zips offer a polished, cohesive look. Invisible nylon coil zips are also an option for those who want a concealed closure.

Types of Nylon Coil Zips for Bag Making

Closed-End Nylon Coil Zips

These zips have a stopper at the end, preventing the slider from detaching. They are ideal for pockets, small pouches, and fixed closures.

Open-End Nylon Coil Zips

Designed for applications where the zip needs to separate completely, such as jackets or expandable bags.

Continuous Nylon Coil Zips

These are long zipper tapes without pre-attached sliders, allowing you to cut the desired length. Continuous zippers are cost-effective and versatile for large projects.

Tips for Using Nylon Coil Zips in Bag Making

Selecting the Right Size

The size of the zipper is determined by the width of its coil. Use:

• #3 Zippers for lightweight bags and interior pockets.
• #5 Zippers for handbags, totes, and medium-sized bags.
• #10 Zippers for heavy-duty duffels and travel bags.

Preparing the Zipper

• Trim the zipper tape to the required length if using a continuous zipper.
• Apply a small amount of fabric glue to prevent fraying at the edges.
• Test the slider to ensure smooth movement before sewing.

Sewing Techniques

• Use a zipper foot on your sewing machine for precise stitching.
• Secure the zipper with basting tape or pins before stitching to avoid misalignment.
• For curved edges, snip small notches into the zipper tape to allow it to bend smoothly.

Adding Reinforcements

Reinforce the ends of the zipper with bar tacks to enhance durability, especially for bags carrying heavy loads.

Common Problems and Solutions When Using Nylon Coil Zips

Problem: Slider Sticks or Catches

• Solution: Apply a small amount of zipper lubricant or wax along the coil for smoother operation.

Problem: Fraying Zipper Tape

• Solution: Seal the raw edges with a lighter or fabric glue to prevent unraveling.

Problem: Misaligned Zipper Installation

• Solution: Use washable markers to mark alignment points before sewing.

Innovative Uses of Nylon Coil Zips in Bag Making

Beyond standard closures, nylon coil zips can be used creatively:

• Decorative Elements: Brightly colored zippers can double as accents or trim.
• Expandable Compartments: Add zippers to create adjustable sections in bags.
• Hidden Pockets: Incorporate invisible zippers for secret compartments.

Caring for Bags with Nylon Coil Zips

To extend the life of your nylon coil zippers:

• Clean Regularly: Wipe down with a damp cloth to remove dirt and debris.
• Avoid Overloading: Excessive strain can damage the zipper teeth or slider.
• Lubricate Occasionally: A dab of silicone lubricant keeps zippers running smoothly.

Conclusion

Incorporating nylon coil zips into your bag-making projects offers unparalleled versatility, durability, and style. From their flexible design to their wide range of applications, nylon coil zips are an indispensable tool for crafters and professionals alike. By selecting the right type and mastering sewing techniques, you can create bags that are both functional and visually stunning.
