How to Properly Store and Maintain Flexible Magnetic Sheeting

Flexible magnetic sheeting is a versatile and durable material widely used in printing, signage, and various industrial applications. To maintain its magnetic strength and overall quality over the years, proper storage and handling are essential. Here’s what you need to know to ensure longevity and performance.

1. Protecting Against Moisture & Water Exposure

Flexible magnetic sheeting is typically made from a rubber-ferrite blend, making it resistant to minor moisture exposure. However, prolonged contact with water or high humidity can cause issues such as swelling, warping, or delamination. Additionally, adhesive-backed sheeting may lose its sticking power when exposed to moisture.

✅ Best Practice: Store your magnetic sheeting in a dry, climate-controlled area. If using in humid environments, consider applying a protective laminate or coating to prevent water damage.

2. Temperature & Freezing Conditions

Magnetic sheeting can withstand freezing temperatures without losing strength, but extreme cold may make the material brittle and more prone to cracking when bent. Additionally, repeated freeze-thaw cycles can introduce moisture damage, especially if stored outdoors.

✅ Best Practice: Avoid long-term outdoor storage in freezing conditions. When used outdoors, ensure the surface is dry and smooth to prevent damage.

3. Stacking & Long-Term Storage

When storing multiple sheets, stacking is a common method. However, prolonged compression can cause the lower layers to lose flexibility, leading to curling or warping.

✅ Best Practice:

• Store sheets flat in small stacks.

• If stacking in large quantities, use a separator (cardboard or plastic) between layers to distribute pressure evenly.

• If storing in rolls, keep them in a vertical position to prevent flattening on one side.

4. Cleaning & Handling

Over time, dust and dirt can accumulate on magnetic sheets, reducing their adhesion and overall performance. Cleaning your sheeting regularly ensures longevity.

✅ Best Practice:

• Wipe with a dry microfiber cloth.

• For tougher stains, use a mild detergent solution (avoid harsh chemicals that may degrade the surface).

• If the sheeting has adhesive backing, avoid excessive handling before application to maintain its sticking power.

5. Maintaining Magnetic Strength Over Time

Flexible magnets generally maintain their strength for many years if stored properly. However, certain conditions can lead to demagnetization, such as:

• Exposure to excessive heat (above 70°C or 158°F)

• Strong external magnetic fields nearby

• Physical damage, including warping or creasing

✅ Best Practice: Keep sheets away from heat sources, store them in their original shape, and avoid placing them near strong magnetic fields.

Summary of Best Practices

✔ Store flat or rolled in a dry, temperature-controlled space.
✔ Keep away from moisture and excessive heat.
✔ Use separators when stacking to prevent warping.
✔ Clean regularly with a soft cloth to maintain adhesion.
✔ Avoid storing near strong external magnetic fields to preserve strength.

By following these simple storage and maintenance guidelines, you can ensure that your flexible magnetic sheeting remains in optimal condition for years to come.
