Structure Options: 3 Magnetic Zipper Closure Layouts (Choose by “Strength vs. Flexibility”)

Our magnetic zipper closure strip can be built with three internal layouts. All options use a protective outer tube (EVA/TPU/Plastic tube), while the inside core determines closing strength, flex feel, and how “forgiving” it is on curved openings.

Option A — Alternating (1 Magnet + 1 Silicone Spacer)

Magnetic zipper closure cross-section with two magnets then silicone spacer (MM–S repeat) inside a flexible tube.

Best for: softer feel, smoother bending, curved openings
Layout: M | S | M | S | M | S ...
Why buyers choose it:

• More flexible, easier to follow curves
• Softer hand-feel due to silicone spacing
• Great balance for pockets / apparel openings / sleeve edges

Typical core examples:

• Magnet: 3×6mm N35 ou 3×10mm N52
• Spacer: 3×10mm silicone
• Standard OD: ~3.5mm; length 100mm / 160mm / custom

Option B — Full-Magnet (Continuous Magnets)

Magnetic Zipper Closure Structure B (Full-Magnet Core)

Best for: maximum holding force, straight openings, premium “snap-close”
Layout: M | M | M | M | M ...
Why buyers choose it:

• Strongest attraction along the entire length
• Feels most like a “magnetic zipper” when closing
• Idéal pour bag openings, structured caseset clean-edge closures

Typical core examples:

• Magnet: 3×6mm N35 ou 3×10mm N52
• Standard OD: ~3.5mm; length 100mm / 160mm / custom

Option C — Grouped (2 Magnets + 1 Silicone Spacer)

Magnetic Zipper Closure Structure C (M–S Alternating Core)

Best for: strong closing + extra flexibility (balanced “power & comfort”)
Layout: M | M | S | M | M | S ...
Why buyers choose it:

• Strong “closing points” from paired magnets
• Silicone gaps give better flexibility than full-magnet design
• Great for fashion goods where both hold + comfort matter

Typical core examples:

• Magnet: 3×6mm N35
• Spacer: 3×20mm silicone
• Standard OD: ~3.5mm; length 100mm / 160mm / custom

Quick Selection Guide

• Need maximum strength? → Option B (Full-Magnet)
• Need best flexibility/soft feel? → Option A (Alternating)
• Need a balanced “strong + flexible”? → Option C (Grouped)
