Extra-Large Copper Foil Sheet – 30cm x 20cm, Single-Side Conductive

Get more coverage in a single piece with this extra-large copper foil sheet—a massive 30cm x 20cm, far wider and longer than standard copper tape rolls. With one solid sheet, you can cover large areas seamlessly, without having to overlap narrow strips.

Unlike copper tape on a roll, which often comes in widths of just 5–10mm, this sheet gives you a smooth, continuous surface that’s perfect for shielding, grounding, and creating custom shapes. It arrives perfectly flat—no curl memory, no creases—so it’s ready for precise work right out of the package.

Because it is conductive only on one side, you can control exactly where conductivity is applied, making it safer for electronics and more versatile for creative projects.

Why choose this sheet over a roll?

• Much larger coverage – 30cm x 20cm versus narrow tape widths
• Seamless application – no joins or overlaps needed
• Better for cutting – create clean shapes and large custom patterns
• More precise results – edges stay neat, no adhesive bleed

Features:

• Dimensions: 30cm x 20cm
• Single-side conductive – adhesive side is non-conductive
• Easy to cut, shape, and handle
• Ideal for EMI/RFI shielding, grounding, PCB repairs, and crafts
• Perfect for larger-scale applications where rolls are too small

For electronics, repairs, and crafts, this oversized flat copper foil sheet gives you cleaner, faster, and more professional results than a traditional roll of copper tape.
