The A3 format provides greater visual area while retaining the flexibility and convenience of thin magnetic media.

Ultra-Thin 0.3mm Magnetic Paper

Each sheet is only 0.3mm thick, creating a thin and flexible magnetic product suitable for lightweight display applications.

The low-profile construction allows the finished magnetic graphic to sit relatively close to a compatible steel surface and makes the material suitable for projects where bulky rigid magnets would be inappropriate.

This magnetic paper is designed primarily for:

• Printed graphics
• Photos
• Labels
• Signs
• Promotional materials
• Lightweight displays

It is not intended for high-force magnetic holding or lifting.

Matte White Printable Surface

The printable face features a matte white finish.

Unlike a glossy surface, matte material has reduced surface shine and reflection. This can make it particularly useful for:

• Text-heavy designs
• Business graphics
• Educational resources
• Information signs
• Labels
• Office notices
• Promotional content
• Displays viewed under bright lighting

The white surface provides a neutral background for customised printed artwork and graphics.

Matte vs Gloss Printable Magnetic Paper

The choice between matte and gloss printable magnetic paper depends primarily on the appearance required for the finished magnetic product.

Matte magnetic paper provides:

• A non-glossy appearance
• Reduced visible reflections
• A more subdued finish
• Suitability for text and information-heavy designs

Gloss magnetic paper provides:

• A shinier surface
• Greater visible reflection
• A finish often selected for photographic or highly visual graphics

Neither finish is universally better. Select the surface that best suits the intended design, lighting conditions and desired appearance.

Magnetic Photos and Artwork

A3 printable magnetic paper can be used to transform compatible printed photographs and artwork into removable magnetic displays.

Potential applications include:

• Family photos
• Promotional photography
• Artwork

• Business imagery
• Decorative displays
• Portfolio graphics

The magnetic backing allows the finished item to attach directly to a compatible ferromagnetic surface without requiring permanent adhesive.

Promotional and Business Magnets

Businesses can use printable magnetic paper to create customised promotional graphics and information.

Potential applications include:

• Promotional signs
• Branded graphics
• Business information
• Service reminders
• Product information
• Event materials
• Marketing displays

A single sheet may be used to create multiple:

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

Use appropriate cutting equipment and suitable safety precautions.

Printer Compatibility

Printer technology and settings have not been specified for this product.

Before printing, check your printer manufacturer's specifications to confirm that the printer can safely accept:

• A3-sized media
• 0.3mm thick media
• Flexible magnetic printing material
• The required media feed path

Do not assume that a printer can process magnetic paper simply because it accepts standard A3 paper.

Where possible, test a single sheet first and use media settings appropriate to the material according to the printer manufacturer's instructions.

Compatible Magnetic Surfaces

The flexible magnetic backing 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 can also be weakly magnetic or non-magnetic and should be tested before relying on magnetic attachment.

Not Compatible with Glassboards

Glassboards generally create a substantial gap between the flexible magnetic material and the underlying steel or magnetic component.

Flexible magnetic products do not provide the concentrated magnetic field required to work effectively across this additional distance.

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

Printable magnetic paper is designed primarily for lightweight magnetic display, signage and identification applications.

It should not be compared directly with rigid neodymium, ferrite, Alnico or Samarium Cobalt magnets designed for higher-force magnetic applications.

Practical magnetic attachment depends on factors including:

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

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

Surface Area and Magnetic Holding

Flexible magnetic products generally benefit from having a larger area in direct contact with the target steel.

A complete A3 sheet provides a substantial magnetic contact area when positioned flat against compatible steel.

If the sheet is cut into smaller pieces, each piece has less magnetic surface area available for attachment.

Practical holding performance can therefore change according to the dimensions and shape of the finished magnetic graphic.

Air Gaps and Surface Contact

For best practical magnetic attachment, maximise direct contact between the magnetic backing and compatible steel.

Holding can be reduced by:

• Thick paint
• Powder coating
• Protective films
• Dirt
• Dust
• Rust
• Curved surfaces
• Uneven steel
• Material positioned between the magnetic face and target

Clean, flat contact generally provides better magnetic attachment.

Flexible Magnetic Paper vs Rigid Magnets

Printable magnetic paper and rigid permanent magnets serve different purposes.

Flexible printable magnetic paper is particularly suitable for:

• Printed graphics
• Photos
• Signs
• Labels
• Promotional materials
• Lightweight displays

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

• Higher-force holding
• Mechanical assemblies
• Fixtures
• Magnetic closures
• Industrial magnetic systems

This 0.3mm printable magnetic paper should therefore be considered lightweight flexible magnetic display media, rather than a high-strength holding magnet.

Permanent Magnetic Operation

The flexible magnetic backing is permanently magnetic during normal use.

It requires:

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

Once printed, position the magnetic backing against a compatible ferromagnetic surface.
