5 Pack of A3 Printable Magnetic Sheets

This product is supplied as a pack of five individual A3 magnetic sheets.

Each sheet measures:

• 420mm long
• 297mm wide
• 0.3mm thick

The 5-pack provides multiple sheets for creating individual designs, testing different layouts, producing small promotional runs or preparing several magnetic signs or graphics at once.

The sheets can be used at their full A3 dimensions or, where appropriate for the application and printing process, cut into smaller magnetic pieces after printing.

A3 Size for Larger Magnetic Graphics

At 420mm x 297mm, A3 provides approximately twice the printable area of an A4 sheet.

The larger format can be useful for:

• Magnetic posters
• Promotional graphics
• Retail signage
• Educational displays
• Office notices
• Larger photographs
• Event graphics
• Product information
• Directional signs
• Presentation materials

A3 magnetic paper provides more visual space while retaining the convenience of a thin, flexible magnetic backing.

Ultra-Thin 0.3mm Profile

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

The slim profile helps the finished magnetic graphic sit relatively close to a compatible metal surface.

This type of material is intended primarily for lightweight display, identification and promotional applications, rather than high-force magnetic holding or lifting.

Matte White Printable Surface

The printable side features a matte white finish.

A matte surface provides a non-glossy appearance and reduces reflections compared with a glossy surface, which can be useful for:

• Text-heavy designs
• Business graphics
• Educational materials
• Signs
• Labels
• Office information
• Promotional content
• Displays viewed under bright lighting

The white surface also provides a neutral base for printed artwork and graphics.

Matte vs Gloss Printable Magnetic Paper

Choosing between matte and gloss magnetic paper generally depends on the appearance required for the finished product.

Matte magnetic paper provides:

• A non-glossy appearance
• Reduced surface reflections
• A subdued finish
• Suitability for text, signs and professional graphics

Gloss magnetic paper provides:

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

Neither finish is universally better. The most appropriate option depends on the intended design, lighting conditions and desired appearance.

Magnetic Photos and Artwork

A3 printable magnetic paper can be used to turn compatible printed photos, illustrations and artwork into removable magnetic displays.

Potential uses include:

• Family photos
• Promotional photography
• Artwork
• Children's drawings
• Event graphics
• Business imagery
• Decorative displays
• Portfolio pieces

The magnetic backing allows the finished piece to be attached to a suitable ferromagnetic surface without requiring permanent adhesive.

Promotional and Business Magnets

Businesses can use printable magnetic sheets to create customised promotional material in-house or as part of a dedicated printing workflow.

Potential applications include:

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

Magnetic graphics can be particularly useful where information needs to be removed, updated or repositioned without leaving adhesive residue on the underlying compatible steel surface.

Retail and Point-of-Sale Displays

The A3 format can be useful for creating larger removable retail graphics.

Potential applications include:

• Promotional messages
• Product information
• Temporary sale signs
• Pricing displays
• Directional graphics
• Stock identification
• Point-of-sale material

Where the underlying fixture is made from compatible ferromagnetic steel, the magnetic backing allows graphics to be changed without permanent adhesives.

Education and Classroom Applications

Printable magnetic paper can be used to create customised educational resources.

Potential applications include:

• Classroom displays
• Learning graphics
• Diagrams
• Timetables
• Educational signs
• Maps
• Charts
• Visual learning aids
• Magnetic labels

Custom magnetic pieces can be repositioned during lessons where the available teaching surface is compatible with flexible magnetic material.

Office Organisation

A3 magnetic sheets can also be used to create removable workplace information and organisation tools.

Potential applications include:

• Staff notices
• Schedules
• Workflow information
• Magnetic labels
• Safety reminders
• Instructions
• Calendars
• Planning graphics

The ability to remove and reposition magnetic information can be useful where displays need to change regularly.

Cutting into Smaller Magnetic Pieces

Although supplied as A3 sheets, the material may be cut into smaller pieces or custom shapes where appropriate.

This can allow a single sheet to produce:

• Multiple labels
• Small promotional magnets
• Photo magnets
• Name labels
• Product identifiers
• Educational pieces
• Custom graphics

When cutting, use appropriate tools and methods for thin flexible magnetic sheet material and take care around sharp cutting implements.

Printer Compatibility

Printer technology and settings have not been specified for this magnetic paper.

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 paper path and feed method

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

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

Compatible Magnetic Surfaces

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

• Mild steel
• Iron
• Magnetic steel
• Compatible steel cabinets
• Steel shelving
• Magnetic notice surfaces
• Suitable appliances and equipment

The material will not magnetically attach to inherently non-magnetic surfaces such as:

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

Many stainless steel grades are also weakly magnetic or non-magnetic and should be tested before relying on magnetic attachment.

Not Compatible with Glassboards

Glassboards commonly have a glass surface positioned between the magnetic product and the underlying magnetic or steel layer.

This additional distance significantly reduces the effectiveness of flexible magnetic materials.

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

For glassboards, use magnetic products specifically designed and rated for that application.

Magnetic Performance

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

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

Practical magnetic attachment depends on factors including:

• 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 can benefit from having a larger area in contact with the target surface.

A full A3 sheet provides a large contact area when applied flat against compatible steel.

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

Practical holding may therefore change depending on the size and shape of the finished magnetic graphic.

Keep the Magnetic Face Flat

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

Holding can be reduced by:

• Curved surfaces
• Dirt
• Dust
• Rust
• Uneven steel
• Thick paint
• Protective coatings
• Gaps behind the sheet

Clean, flat contact generally provides better magnetic attachment than an uneven or heavily coated surface.

Flexible Magnetic Paper vs Rigid Magnets

Printable magnetic paper serves a different purpose from rigid permanent magnets.

Flexible magnetic paper is particularly useful for:

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

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

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

This A3 printable product should therefore be treated as flexible magnetic display media, not as a high-strength holding magnet.

Permanent Magnetic Operation

The magnetic backing is permanently magnetic during normal use.

It requires:

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

Simply position the magnetic side against a compatible ferromagnetic surface.
