How Self-Adhesive Magnetic Sheets Work

Self-adhesive magnetic sheeting combines an adhesive surface with a flexible magnetic face.

The adhesive side is used to bond the item you want to make magnetic, while the opposite magnetic side provides attraction to compatible ferromagnetic surfaces.

A typical application involves:

1. Preparing the item you want to make magnetic.
2. Ensuring the bonding surface is clean, dry and free from contamination.
3. Removing the protective adhesive liner.
4. Applying the item carefully to the exposed adhesive.
5. Applying firm, even pressure across the bonded area.
6. Allowing the adhesive to establish according to its requirements.
7. Positioning the magnetic face against compatible steel.

The adhesive side itself is non-magnetic.

Turn Lightweight Items into Magnetic Products

A key advantage of self-adhesive magnetic sheeting is the ability to convert ordinary lightweight items into removable magnetic products.

The adhesive side may be used with suitable materials such as:

• Photos
• Paper
• Card
• Printed graphics
• Lightweight signs
• Labels
• Calendars
• Promotional material
• Educational resources
• Craft components

Once bonded, the magnetic face allows the completed item to be attached, removed and repositioned on compatible ferromagnetic surfaces.

Thin 0.4mm Flexible Profile

Each sheet is only 0.4mm thick, creating a thin and flexible magnetic backing.

This low-profile construction can be particularly useful where:

• A thin magnetic backing is preferred
• The finished product should remain lightweight
• Installation depth is limited
• Material needs to be cut into smaller pieces
• A broad area of magnetic backing is required

The material is intended primarily for lightweight magnetic display and identification applications, rather than high-force magnetic holding.

Standard A4 Size

Each magnetic sheet measures 210mm x 297mm, matching standard A4 dimensions.

The A4 format provides a practical area for:

• Full-page magnetic signs
• Notices
• Photographs
• Promotional graphics
• Educational displays
• Calendars
• Multiple labels
• Smaller custom-cut magnetic pieces

Its familiar dimensions also make planning layouts and cutting patterns straightforward.

Self-Adhesive Backing

The adhesive backing eliminates the need to separately apply glue to many common lightweight materials.

Potential applications include bonding compatible:

• Paper
• Card
• Photographs
• Printed graphics
• Labels
• Lightweight display materials

The specific adhesive type and brand have not been supplied.

Adhesive performance depends on factors including:

• Material being bonded
• Surface cleanliness
• Surface texture
• Application pressure
• Environmental conditions
• Temperature
• Exposure conditions

For critical or long-term applications, test adhesion using the actual materials and conditions involved.

Surface Preparation for Adhesive Bonding

Correct preparation of the bonding surface can improve adhesive performance.

Before applying the sheet:

• Ensure the surface is clean
• Remove dust and debris
• Remove grease and oil
• Make sure the surface is dry
• Avoid unnecessary contact with exposed adhesive
• Position carefully before applying full pressure
• Apply firm, even pressure across the bonded area

Textured, porous, contaminated or difficult-to-bond materials may require testing before use.

Magnetic Photos and Artwork

• Calendars
• Instructions

The ability to reposition the finished magnetic product can be useful in workplaces where information changes regularly.

Cutting into Smaller Magnetic Pieces

Although supplied in A4 sheets, the material can be cut into smaller pieces or custom shapes where appropriate.

A single sheet may be used to create multiple:

• Magnetic labels
• Photo magnets
• Promotional pieces
• Name labels
• Product identifiers
• Educational pieces
• Craft components

Plan the required dimensions before removing the protective adhesive liner where possible.

Use appropriate cutting tools and follow suitable safety precautions.

Compatible Magnetic Surfaces

The magnetic face is designed to attach to suitable ferromagnetic surfaces, including:

• Mild steel
• Iron
• Magnetic steel
• Compatible steel cabinets
• Steel shelving
• Steel storage systems
• Suitable appliances
• Magnetic notice surfaces

It will not effectively attach magnetically to inherently non-magnetic materials such as:

• Aluminium
• Copper
• Brass
• Plastic
• Timber
• Standard glass

Many stainless steel grades may also be weakly magnetic or non-magnetic. Test the intended surface before relying on magnetic attachment.

Not Compatible with Glassboards

Glassboards typically place a layer of glass between the magnetic product and the underlying steel or magnetic component.

This creates an air gap that substantially reduces the effectiveness of flexible magnetic materials.

Please note, this product alongside all flexible magnetic products are not compatible with glassboards.

For glassboard applications, use magnetic products specifically designed and rated for use through the glass surface.

Magnetic Performance

Flexible magnetic sheeting is primarily designed for lightweight display, signage, promotional and identification applications.

It should not be compared directly with rigid neodymium or ferrite magnets designed for concentrated, higher-force magnetic holding.

Practical magnetic attachment depends on factors including:

• Available magnetic surface area
• Target steel composition
• Target steel thickness
• Surface flatness
• Air gaps
• Paint and coatings
• Curvature
• Weight of the attached item
• Installation orientation

No specific pull force or magnetic flux density in Gauss has been supplied.

Surface Area and Magnetic Holding

Flexible magnetic products generally perform best when a large proportion of their magnetic surface is in direct contact with compatible steel.

A complete A4 sheet provides substantially more magnetic contact area than a small piece cut from the same material.

If sheets are cut into smaller pieces, each individual piece will have less magnetic surface area available for attachment.

Use sufficient magnetic backing for the size and weight of the item being displayed.

Air Gaps and Surface Contact

For best practical attachment, maximise contact between the magnetic face and the compatible steel surface.

Magnetic holding can be reduced by:

• Thick paint
• Powder coating
• Protective films
• Dirt
• Dust
• Rust
• Curved surfaces
• Uneven surfaces
• Other material positioned between the magnet and steel

Clean, flat contact generally provides better magnetic attachment.

Flexible Magnetic Sheet vs Rigid Magnets

Flexible magnetic sheeting and rigid permanent magnets serve different purposes.

Self-adhesive flexible magnetic sheets are particularly suitable for:

• Photos
• Graphics
• Signs
• Labels
• Cards
• Promotional materials
• Lightweight displays

Rigid magnets, such as neodymium and ferrite magnets, are generally more appropriate for:

• Higher-force holding
• Mechanical assemblies
• Fixtures
• Closures
• Industrial magnetic systems

This 0.4mm material should therefore be considered a lightweight flexible magnetic backing product, rather than a high-strength holding magnet.

Permanent Magnetic Operation

The magnetic face is permanently magnetic during normal use.

It requires:

• No electricity
• No batteries
• No charging
• No external power supply

Once the required material has been bonded to the adhesive side, position the magnetic face against a compatible ferromagnetic surface.

• Leave the protective adhesive liner in place until required
• Protect adhesive surfaces from dust and contamination
• Avoid sharp folds and permanent creases
• Avoid excessive heat unless temperature suitability has been confirmed
• Test adhesive compatibility for critical applications

Creasing the material can affect its appearance and reduce the amount of magnetic surface that sits flat against the target.

Please Note

This product contains 25 individual A4 Self-Adhesive Magnetic Sheets, each measuring 210mm x 297mm x 0.4mm thick.

The adhesive side is non-magnetic and is designed for bonding suitable lightweight materials to the sheet. The opposite magnetic face allows the completed item to attach to compatible ferromagnetic surfaces.

This flexible magnetic material is intended primarily for lightweight applications such as photos, cards, signs, labels, promotional graphics, educational resources and displays, rather than high-force holding or lifting.

No specific pull force, Gauss rating, magnetic material grade, adhesive type or brand, dimensional tolerance, maximum operating temperature or environmental rating has been supplied and these specifications should not be assumed.

Actual magnetic attachment depends on the available magnetic surface area, target material, surface flatness, air gaps, coatings, weight of the attached item and installation orientation. Adhesive performance also depends on the material being bonded, surface preparation and environmental conditions.

Please note, this product alongside all flexible magnetic products are not compatible with glassboards.
