Custom PVC/EVA tube magnetic closure structures, magnet spacing and specifications for bags, pouches and soft goods.

For buyers searching for a Magnetic Zipper Closure, Richarms offers a clearly defined alternative: discrete neodymium magnets arranged inside a flexible PVC or EVA tube. This hidden magnetic attachment creates an intuitive closing action for bags, pouches, sleeves, pockets, apparel and other soft products.

Unlike a conventional toothed zipper, this customizable component has no zipper teeth or slider. Instead, we select the tube, magnet size, internal spacing and finished length according to the fabric, bend radius, target holding force, opening feel and assembly method.

Magnetic Zipper Closure Structure Explained

• Flexible outer tube: We use PVC or EVA according to the required size and application.
• Internal magnetic elements: The tube contains discrete cylindrical neodymium magnets.
• Optional spacer: We can add silicone or PVC spacer sections to adjust flexibility and closing force.
• Construction: This design uses a non-heat-shrink flexible tube. We apply end treatment only when the finished specification requires it.

Therefore, the product is best understood as a flexible magnetic closure strip. “Magnetic Zipper Closure” describes the buyer’s application, not a conventional zipper mechanism.

Three Internal Arrangement Options

MSM – One Magnet + One Spacer

MSM offers more flexibility. For example, it can suit curved edges, lightweight fabrics and projects that need an easier opening feel.

MMS – Two Magnets + One Spacer

MMS balances holding force and flexibility. As a result, it works well as a starting point for general bag, pouch and sleeve testing.

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

Magnetic zipper closure in bulk production: full-magnet core for strongest closure performance.

MMM – Continuous Discrete Magnets

MMM places individual magnets close together for higher holding force. However, customers should test the final design against the product structure and intended opening force.

Magnetic Zipper Closure Structure B (Full-Magnet Core)

Magnetic zipper closure in bulk production: full-magnet core for strongest closure performance.

Typical Reference Specifications

• Magnet options: 3 × 6 mm N35 or 3 × 10 mm N52
• Typical finished outside diameter: approximately 3.5 mm, depending on the selected tube and internal structure
• Length: sample lengths and project-specific cut-to-length production
• Customization: magnet grade, holding force, tube material, diameter, length, spacing pattern, color and end treatment

These values are references rather than universal specifications. Consequently, we confirm final dimensions, materials and performance through sample testing in the customer’s actual product.

Why Choose This Magnetic Zipper Closure Alternative?

• Self-aligning and intuitive closing action
• Hidden integration inside fabric channels or product edges
• Quiet operation with no exposed teeth or hard metal slider
• Flexible options for straight or curved openings
• Customizable holding and release feel
• Repeatable production after application validation

Magnetic Zipper Closure Applications

Typical applications include handbags, backpacks, organizer pouches, laptop and tablet sleeves, pockets, apparel openings and storage products. In addition, designers can use the strip in other soft goods that need a concealed magnetic closure.

Magnetic Zipper Closure Installation & Development

Customers typically insert the strip into a sewn channel or designed cavity, much like installing a cord inside a fabric edge. First, confirm the channel size and polarity direction. Next, test the bend radius, opening path and end treatment in the finished product.

Our recommended process is simple: share your drawing, sample or application idea; select an initial structure; test a sample in the real product; and then confirm the production specification.

Magnetic Zipper Closure FAQs

Is this a magnetic zipper?

Some buyers use “Magnetic Zipper Closure” as an application term. Structurally, this product is a flexible PVC/EVA tube containing discrete magnets, with optional silicone or PVC spacers. It does not use conventional zipper teeth or a slider.

Which structure should I choose?

MSM prioritizes flexibility, MMS balances flexibility and holding force, and MMM provides higher holding force. Therefore, choose the structure according to the fabric, opening direction, bend radius and target release force.

Can Richarms customize the length and magnetic force?

Yes. We can develop the length, magnet size and grade, spacing pattern, tube material, color and end treatment around the application.

What temperature is suitable?

Standard versions suit normal-use environments up to approximately 80°C. For higher-temperature projects, we confirm a separate material and magnet specification.

Can I order samples?

Yes. We recommend sample testing before production because the complete product design determines the finished opening feel.

Start with an Application Review

Send Richarms your drawing, sample, target length, fabric or substrate, desired holding force and opening method. Then, we will recommend the minimum practical configuration for testing before mass production.
