• Larger signs
• Promotional graphics
• Notices
• Product information
• Point-of-sale displays
• Warehouse identification
• Educational materials
• Planning information
• Custom-cut magnetic components

The sheet can be used at its full A3 size or cut down where smaller magnetic pieces are required.

0.4mm Thin Magnetic Sheeting

At only 0.4mm thick, this magnetic sheet has a thin and flexible profile.

The low thickness makes it suitable for applications where:

• A lightweight magnetic display is preferred
• A low-profile finish is important
• The sheet needs to be easily handled
• Custom shapes need to be cut
• Multiple labels or signs are produced from one A3 sheet

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

White Gloss PVC Surface

The gloss finish provides a smooth presentation surface suitable for applications where a clean, finished appearance is desirable.

Printing and Customisation

The white PVC surface may make this product suitable for various customisation applications; however, specific printer and ink compatibility has not been supplied.

Do not assume compatibility with a particular:

• Inkjet printer
• Laser printer
• UV printer
• Solvent printer
• Eco-solvent printer
• Latex printer
• Thermal printer

Before printing, confirm that the printing equipment, ink system and feed mechanism are suitable for 0.4mm PVC-faced magnetic media.

A test print is recommended before processing larger quantities.

The sheet can also potentially be customised using suitable labels, graphics or other compatible finishing methods.

Cut-to-Size Magnetic Sheet

One of the advantages of flexible magnetic sheeting is the ability to create smaller magnetic components from a larger sheet.

This A3 sheet can be cut into:

• Rectangles
• Squares
• Strips
• Labels
• Tags
• Tabs
• Signs
• Custom shapes

This makes a single A3 sheet useful for producing multiple smaller magnetic labels or display components.

When cutting, use appropriate tools and safe working practices.

Retail and Point-of-Sale Displays

The white gloss surface and removable magnetic attachment make this sheet useful for retail environments.

Potential applications include:

• Price information
• Promotional messages
• Product identification
• Shelf information
• Temporary offers
• Display signage
• Stock notices

Magnetic signs can be repositioned or replaced without permanently modifying a compatible steel display surface.

Warehouse and Industrial Identification

Flexible magnetic sheets are also useful for organising steel shelving, cabinets and other compatible ferromagnetic equipment.

Potential applications include:

• Rack identification
• Bin labels
• Stock locations
• Product codes
• Equipment identification
• Workflow information
• Temporary notices
• Visual management systems

Magnetic labels can be particularly useful in environments where storage locations or information change regularly.

Office Organisation

The A3 magnetic sheet can be used for removable displays on suitable steel surfaces in offices and administrative environments.

Potential applications include:

• Filing cabinet labels
• Planning information
• Scheduling
• Staff notices
• Magnetic signs
• Workflow boards
• Reminders
• Department identification

Unlike permanent adhesive labels, magnetic displays can generally be repositioned when requirements change.

School and Educational Applications

Flexible magnetic sheeting can be used to create reusable educational and classroom materials.

Potential uses include:

• Classroom signs
• Learning resources
• Educational graphics
• Timetables
• Visual schedules
• Magnetic labels
• Teaching aids
• Display materials

Always confirm that the intended classroom surface is magnetically receptive.

Magnetic Attachment

The reverse side of the sheet acts as the magnetic working face and is designed to attach to compatible ferromagnetic surfaces.

Suitable targets can include:

• Mild steel
• Iron
• Magnetic steel
• Steel filing cabinets
• Steel shelving
• Magnetic whiteboards
• Compatible refrigerator surfaces
• Other suitable ferromagnetic surfaces

The sheet does not require electricity or an external power source to remain magnetically attached.

Compatible and Non-Compatible Surfaces

Flexible magnetic sheeting requires a suitable ferromagnetic target.

It can attach to compatible:

• Iron
• Mild steel
• Magnetic steel

It will not magnetically attach directly 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.

If compatibility is uncertain, test the intended surface with a conventional magnet before use.

Magnetic Whiteboard Compatibility

This sheet may attach to a conventional magnetic whiteboard where the board contains a suitable magnetically receptive steel layer.

However, not all dry-erase whiteboards are magnetic.

A surface being suitable for whiteboard markers does not automatically mean it will accept magnetic products.

Test the board before use if its construction is unknown.

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

Surface Area and Magnetic Holding

Flexible magnetic sheeting behaves differently from rigid rare earth magnets.

Its holding ability depends significantly on the amount of magnetic surface area in contact with the target.

A larger section of magnetic sheet generally provides more total magnetic contact than a very small piece cut from the same material.

Performance can therefore vary depending on:

• Size of the finished magnetic piece
• Available contact area
• Target steel thickness
• Target material
• Surface coatings
• Paint
• Dirt or contamination
• Surface flatness
• Air gaps
• Installation orientation

If the sheet is cut into very small pieces, each piece will have less total magnetic contact area.

Air Gaps and Surface Coatings

Magnetic attraction decreases when physical separation exists between the magnetic sheet and the target surface.

Potential sources of air gaps include:

• Paint
• Powder coating
• Protective films
• Labels
• Dirt
• Surface irregularities
• Decorative coverings

For best magnetic contact, use the sheet against a clean, flat and compatible ferromagnetic surface.

Lightweight Magnetic Display

At 0.4mm thick, this product is designed for lightweight applications.

Suitable applications include:

• Signs
• Labels
• Graphics
• Notices
• Calendars
• Promotional displays
• Educational materials
• Organisational systems

It should not be treated as a high-force holding magnet or used for lifting heavy objects.

Where a specific holding capacity is required, the finished application should be tested under realistic operating conditions.

Flexible Magnetic Sheet vs Rigid Neodymium Magnets

Flexible magnetic sheeting and rigid neodymium magnets serve different purposes.

Flexible magnetic sheet is particularly useful for:

• Large-area displays
• Signs and labels
• Lightweight graphics
• Cut-to-size applications
• Repositionable information
• Thin, flexible magnetic products

Neodymium magnets are generally preferred for:

• High magnetic force relative to size
• Compact mechanical assemblies
• Strong holding applications
• Sensors
• Engineering applications

For signage, labelling and large-area lightweight displays, flexible magnetic sheeting often provides a more practical format.

Permanent Magnetic Operation

This flexible magnetic sheet operates using permanent magnetic attraction.

It requires:

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

The magnetic working face remains continuously magnetic during normal use.

Please Note

The Magnetic Sheet – A3 x 0.4mm | PVC White Gloss measures approximately 420mm x 297mm x 0.4mm thick and features a white gloss PVC presentation face with a magnetic working surface on the reverse.

This product is intended for lightweight display, signage, labelling, promotional and organisational applications rather than high-force holding or lifting.

Specific printer compatibility, ink compatibility, magnetic pull force, magnetic flux density, operating temperature and detailed magnetic composition have not been supplied and should not be assumed.

If the sheet is to be printed, confirm that the printer, ink system and feed mechanism are suitable for 0.4mm PVC-faced magnetic media and perform a test before production.

Magnetic holding performance depends on factors including the size and surface area of the finished piece, target material, target steel thickness, surface coatings, contact quality, air gaps and installation orientation.

The magnetic working face requires a suitable ferromagnetic target such as iron or magnetic steel. It will not attach directly to aluminium, copper, brass, plastic, timber or standard glass, and many stainless steel grades may also be weakly magnetic or non-magnetic.

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