Continuous Zipper Chain – Zipper by the Metre

What Is Continuous Zipper Chain?

Continuous zipper chain is zipper tape supplied in a continuous length rather than in a fixed ready-made size. It is also known as zipper tape, zipper chain by the metre, zipper by the meter, continuous zip or metre zipper.

Unlike ready-made zippers, continuous zipper chain does not arrive with a pre-determined finished length, lower stop, separating box or completed end construction. The chain is cut according to the actual project requirement, then completed with compatible sliders, stops or other finishing components depending on the intended application.

This makes continuous zipper chain especially useful where one workshop produces several different zipper lengths, where the closure line is unusually long, or where the same project includes straight, curved or wraparound closures. Tarpaulin workshops, tent manufacturers, awning makers, bag producers, upholstery workshops and technical textile businesses often use continuous zipper chain because it can be adapted to the product rather than forcing the product to fit a standard zipper length.

Continuous Zipper Chain vs. Ready-Made Zippers

Where Is Continuous Zipper Chain Used?

The right application depends on the zipper construction, tooth type, tape structure, slider system and expected load. Continuous zipper chain can be used in many textile, outdoor and industrial-style applications when the correct zipper type is selected.

• Tarpaulins and covers: Vehicle tarpaulins, protective covers, industrial covers, storage covers and flexible textile enclosures.
• Tents and camping products: Tent entrances, camping covers, textile shelters, sleeping equipment covers and outdoor storage products.
• Awnings and shade systems: Awning panels, side covers, shade textiles, windbreaks and modular outdoor covers.
• Bags and cases: Equipment bags, sports bags, tool bags, organiser bags, carrying cases and custom textile covers.
• Outdoor products: Camping gear, technical textile products, outdoor storage, protective equipment and weather-exposed accessories.
• Workshop and repair applications: Replacing damaged zipper sections, producing custom zipper lengths and repairing tents, tarpaulins, bag covers or outdoor textiles.
• Special production: Curved, long, wraparound or non-standard closure lines where ready-made zippers are not suitable.

Continuous Zipper Chain Types

Continuous zipper chain should be selected according to tooth construction, zipper type, coating requirement, closure shape and the product’s expected exposure to load, movement, moisture and weather. The category includes nylon coil, molded plastic, PU-coated and TPU-coated options for different projects.

TPU-Coated Type 10 Nylon Coil Zipper Chain

TPU-Coated Type 10 Nylon Coil Zipper Chain is designed for projects that need a flexible zipper structure with added resistance to direct water entry along the closure line. It can be used in outdoor bags, technical covers, tarpaulins, tents, outerwear and weather-exposed textile products when the zipper system is suitable for the final construction.

TPU coating can provide a thinner and more flexible surface than some conventional coated zipper systems. However, the zipper chain alone does not make the complete product waterproof. Overall water performance depends on the main fabric, seams, needle holes, seam sealing, zipper-end finishing, closure direction and full product construction.

PU-Coated Type 10 Nylon Coil Zipper Chain

PU-Coated Type 10 Nylon Coil Zipper Chain is a continuous coated zipper option for outerwear, bags, tarpaulins, tents and outdoor textile products. It can be considered when the zipper line needs a protected surface and the project requires custom cutting by the metre.

Before choosing a PU-coated zipper chain, check the required length, slider compatibility, tape colour, textile thickness and whether the zipper will run through a straight, curved or wraparound closure line. A compatible slider is essential for smooth zipper movement and reliable tooth engagement.

PU-Coated Type 8 Zipper Chain

PU-coated Type 8 zipper chain can be used in bags, technical covers, outdoor products and projects that require a more substantial zipper profile than lightweight zipper tape. It should be selected according to the real project requirements rather than tooth size alone.

A thicker zipper chain may create a more visible closure line and can suit structured products. On lightweight, soft or sharply curved materials, however, a large zipper profile may create stiffness or affect the appearance of the sewing line. Always test the selected chain on the actual fabric before production.

Type 20 / #10 Nylon Coil Zipper Chain for Tarpaulins and Tents

Type 20 / #10 Nylon Coil Zipper Chain is intended for tarpaulins, tents, awnings, fabric covers, camping gear and flexible outdoor textile applications. Its nylon coil construction can provide a softer and more flexible zipper line than a rigid molded-tooth structure.

This type of zipper chain is useful for products that fold, bend, roll or compress during use. For example, tent doors, fabric covers, tarpaulin systems and flexible outdoor enclosures may benefit from a nylon coil zipper chain when the compatible slider and the tape structure are selected correctly.

For double-sided access or installations where both sides of the closure need to be operated, a compatible Type 20 Nylon Coil Double Pull Slider can be selected according to the final zipper system.

Type 9 Molded Plastic Zipper Chain for Tarpaulins and Tents

Type 9 Molded Plastic Zipper Chain is suitable for tarpaulins, tents, awnings, vehicle covers, heavy textile structures and projects where a more visible, structured plastic tooth profile is required.

Molded plastic zipper chain can be preferred when the closure should have more defined teeth and a stronger visual structure. It may suit larger covers, more structured bag applications, industrial-style textile products and projects where the zipper is expected to remain visible as part of the design.

Custom production may allow zipper tape and tooth colour planning for suitable orders. Before starting custom production, confirm the sample, colour direction, intended use, required quantity, zipper type, slider system and expected production conditions.

Nylon Coil Zipper Chain vs. Molded Plastic Zipper Chain

Nylon coil and molded plastic zipper chains solve different production needs. The correct choice depends on flexibility, visual appearance, fabric weight, closure shape, expected use and slider compatibility.

How to Choose the Correct Slider for Continuous Zipper Chain

The slider is one of the most important parts of a continuous zipper system. A zipper chain will not perform correctly if the slider does not match the zipper type, tooth construction, chain size and intended opening direction.

Do not use a slider simply because it looks similar. The internal channel, tooth engagement and slider structure must be compatible with the exact zipper system. An incompatible slider may cause resistance, tooth separation, uneven closure, poor alignment or premature wear.

• Match the slider with the zipper type and tooth structure.
• Check whether the project requires a single slider, double pull slider or two-way arrangement.
• Confirm the correct orientation before inserting the slider onto the chain.
• For coated zipper chain, use a slider suitable for the coated zipper construction.
• Consider whether the closure will be operated from one side or both sides.
• Test the zipper chain and slider together on a sample before cutting the full production quantity.

How to Calculate How Much Zipper Chain You Need

Measure the real closure line rather than estimating from the overall size of the product. A tent door, tarpaulin opening, awning panel, bag lid or curved cover may require a different amount of zipper chain even when the finished products appear similar in size.

• Measure the actual zipper sewing line on the product or pattern.
• Measure curved and wraparound closure lines along the real sewing path.
• Calculate each separate zipper line individually for products with more than one opening.
• Add allowance for sample production, cutting, end finishing and possible production waste.
• Plan separately for sliders, stops and any finishing components required by the project.
• For repeated production, calculate the total chain requirement per model before placing the order.

How to Choose Water-Repellent Zipper Chain

PU- and TPU-coated continuous zipper chains are selected when the zipper line may be exposed to rain, moisture, splash or outdoor conditions. Their coated surface can help reduce direct water entry along the zipper line.

However, water-repellent zipper chain is only one part of a weather-protection design. The finished product may still allow water through seams, stitch holes, unsealed fabric edges, zipper ends or other construction areas.

How to Install Continuous Zipper Chain

Continuous zipper chain should be tested and prepared before final sewing. This is especially important for long tarpaulin runs, curved closures, coated zipper tapes and applications that use double pull sliders.

• Mark the zipper line on the real pattern or product before cutting the chain.
• Cut the zipper chain with enough allowance for finishing and testing.
• Insert the compatible slider and confirm smooth opening and closing before sewing.
• Keep both zipper tapes aligned during installation to avoid uneven closure.
• Do not stretch the zipper tape excessively during sewing.
• Test coated zipper chain on the actual fabric before using it in a full production run.
• Plan suitable stops, sewn ends or other finishing methods according to the product’s intended use.

Common Mistakes When Choosing Continuous Zipper Chain

• Choosing zipper chain only by colour without checking the zipper type, tooth structure and slider compatibility.
• Using an incompatible slider with the zipper chain.
• Treating continuous zipper chain like a ready-made zipper without planning the end construction.
• Choosing a zipper type without considering fabric thickness, closure shape and expected use.
• Assuming coated zipper chain makes the complete product fully waterproof.
• Using a large structured tooth profile on lightweight or highly flexible fabric without testing the result.
• Ignoring the need for extra length for cutting, sample work and end finishing.
• Starting production without testing zipper chain, slider, fabric and sewing construction together.
