Full-bond keder bonds the coated fabric around the core perimeter, while traditional line-sealed keder relies on a narrower sealing line. For applications involving fabric tension, rail pulling, outdoor exposure and repeated installation, full-bond construction can provide a more reliable fabric-to-core connection.
What Is Full-Bond Keder?
Full-bond keder is manufactured by wrapping coated fabric around the core and bonding it around the perimeter. Kedermaker uses hot wedge / HF welding knowledge to create a consistent connection between the core and the coated fabric wrap.
This construction is designed for customers who need dependable performance in tents, awnings, marine canvas, tarpaulins and other industrial fabric applications.
What Is Line-Sealed Keder?
Line-sealed keder uses a narrower bonding or sealing area. It may be suitable for basic applications, but the fabric-to-core connection depends heavily on the quality and consistency of the sealing line.
Comparison
Full-Bond Keder
Bonding area: Around the core perimeter
Strength consistency: More consistent fabric-to-core connection
Best for: Demanding fabric structures and repeated installation
Applications: Tents, awnings, marine canvas, tarpaulins and industrial fabric systems
Line-Sealed Keder
Bonding area: Limited sealing line
Strength consistency: More dependent on line seal quality
Best for: Basic or lower-demand applications
Applications: Depends on material, supplier and project requirements
Why Bonding Consistency Matters
Keder often works under tension. It may be pulled through rails, exposed to outdoor weather, rolled for transport and installed repeatedly. A consistent bond between the fabric and the core helps reduce the risk of separation and supports better long-term performance.
When Should You Choose Full-Bond Keder?
Choose full-bond keder when the project involves outdoor use, repeated installation, higher fabric tension, marine conditions, large fabric panels or custom industrial fabric requirements.
FAQ：
Q: Is full-bond keder stronger than line-sealed keder?
A: Full-bond keder provides a larger bonding area around the core, which can create a more consistent fabric-to-core connection for demanding applications.
Q: What applications need full-bond keder?
A: Full-bond keder is recommended for tents, marquees, awnings, marine canvas, tarpaulins and industrial fabric systems.
Q: Can full-bond keder be customized?
A: Yes. Kedermaker can manufacture full-bond keder with custom diameter, flap width, material, color, roll length and packaging.
