Magnetic films – find manufacturers and suppliers

Magnetic films are flexible, magnetized materials that are used to create magnetic adhesion on ferromagnetic surfaces (e.g. steel or iron).

They consist of a combination of magnetic particles and a flexible plastic matrix.

Below you will find an overview of the structure and manufacture, the properties and types of magnetization of magnetic films, as well as an overview of their areas of application, their advantages and information on care and maintenance:

Structure and manufacture of magnetic films:

1. The magnetic material is usually ferrite powder or, more rarely, neodymium particles embedded in a plastic or rubber base.
2. The mixture is formed into thin foils by extrusion or calendering.
3. The foils are provided with specific patterns in a magnetization process.
4. Optionally, a protective layer, adhesive layer or printable surface can be applied.

Properties of magnetic films:

1. Magnetic foil can be bent, cut or punched without losing its magnetic force.
2. Sticks without adhesive and is easy to remove and reposition.
3. The magnetic force remains stable for years.

Magnetization types of magnetic films:

1. Isotropic:
   Uniform magnetization, lower magnetic force.
2. Anisotropic:
   Aligned magnetization, higher magnetic force.
3. Strip magnetization:
   Alternating magnetic poles in strip form.
4. Point magnetization:
   Points with concentrated magnetic force.
5. Special patterns:
   Magnetizations optimized for specific requirements, e.g. holding patterns or individual poles.

Use of magnetic films:

Magnetic films are useful in a variety of applications, from advertising and signage to industrial and creative applications.

1. Advertising and signage technology:
Vehicle signage: temporary advertising or logos on vehicles that can be easily removed.
Displays and exhibition stands: Flexible and reusable material for advertising elements.
Signs and notice boards: For temporary or permanent signage on magnetic surfaces.

2. Office and organization:
Whiteboards: Magnetic films can serve as a writable or printable surface.
Calendars and planners: Flexible elements for organizing work areas.
Document holders: Holding papers or notes on metal surfaces.

3. Industrial applications:
Packaging industry: magnetic films are used to label packaging or machines.
Workshop organization: Marking of tools or storage systems.
Sealing systems: Use in refrigerators or other appliances with magnetic closure systems.

4. Creative and educational applications:
Craft projects: Magnetic picture frames, toys or other DIY projects.
Teaching materials: Creation of magnetic cards, diagrams or games for lessons.
Decoration: Magnetic stickers for fridges or other metal surfaces.

5. Household and everyday life:
Fridge magnets: for attaching notes, photos or shopping lists.
Cupboard and door latches: Magnetic films can be used as a locking mechanism.
Temporary attachments: E.g. for curtains or fly screens.

Advantages of magnetic films:

• Easy to cut, shape and customize.
• Can be glued to various surfaces or adhere directly magnetically.
• Quick installation and removal without residue.
• Affordable compared to rigid magnetic solutions.
• Environmentally friendly alternative to adhesive solutions.

Care and maintenance:

• Clean with a damp cloth to remove dirt or dust that could affect adhesion.
• Store flat or rolled up to avoid creasing or deformation.
• The film should not be loaded beyond its adhesive force.

Magnetic films offer a practical and versatile solution for a wide range of applications.

Here is an overview of the most important criteria to consider when buying magnetic films:

When purchasing magnetic films, it is important to consider various technical and practical aspects to ensure that the sheets meet the specific requirements of your application.

• The strength of the adhesion depends on the thickness of the sheet and the magnetization used (isotropic or anisotropic). For stronger adhesion, anisotropically magnetized films are more suitable.
• Make sure that the target surface is magnetically conductive (e.g. iron, steel). A self-adhesive film can be used for non-magnetic surfaces.
• Which type of magnetization is suitable for your application?
• Strip magnetization: For even adhesion.
• Point magnetization: For punctual adhesion areas.
• Special pattern: Suitable for specific industrial or technical applications.
• Make sure that the film can bear the weight of the objects to be held.
• Thicker films usually offer stronger magnetic force, but are less flexible. Thinner films are more suitable for creative or decorative applications.
• Depending on the thickness and material composition. Flexible films are suitable for curved or uneven surfaces.
• Check the area of application: Standard: Suitable for temperatures up to +80 °C. High temperature variants: For industrial applications requiring higher temperatures.
• Abrasion resistance: Choose films with a protective surface if they are exposed to intensive mechanical stress.
• If the film is to be used for advertising or creative projects, a printable or writable surface is important.
• A self-adhesive backing is ideal for applications on non-magnetic surfaces.
• A protective layer is recommended for applications where the film is exposed to external influences such as moisture or chemicals.
• The available formats:
• Rolls are suitable for large area applications or industrial processes.
• Cut-to-size sheets for smaller projects or specific requirements.
• Custom cuts for special shapes and sizes.
• Magnetic films should meet quality standards such as ISO 9001. Declarations of conformity such as RoHS are important for use in Europe.
• The sheets should guarantee a stable magnetic force for many years.
• Consider the long-term durability and reusability of the films.
• For larger projects, it may be cheaper to buy rolls or large quantities.
• Be aware of possible longer delivery times for custom-made products.
• Check whether the magnetic film is recyclable or made from recycled materials.
• Choose PVC-free magnetic film or those with biodegradable components.
