xDouble Sided Conductive Copper Foil Tape
Reliable EMI Shielding, Grounding & Electrical Repairs — Through-Surface Conductivity
Our double sided conductive copper foil tape combines high-purity copper with a pressure-sensitive conductive adhesive to deliver electrical continuity across both the foil surface and the glue layer. This copper foil tape forms instant, solder-free bonds between contact points, making it a trusted choice for engineers, technicians, and makers who need dependable EMI shielding, static discharge protection, and low-resistance grounding. Each roll of conductive copper tape is engineered to conform to irregular surfaces, resist oxidation, and maintain stable performance in demanding electronic and industrial environments.
Why Choose Our Copper Foil Tape
High-Purity Copper Foil
Every roll is manufactured from high-purity copper, providing low electrical resistance, excellent corrosion resistance, and consistent surface conductivity for reliable shielding and signal integrity.
True Double-Sided Conductivity
Both the copper foil and the adhesive layer conduct electricity. Overlaps, seams, and bonded contact points maintain full continuity — the key advantage of double-sided over single-sided copper tape.
Conductive Acrylic Adhesive
The pressure-sensitive adhesive is loaded with conductive particles, creating a stable electrical bond the moment it makes contact. It adheres firmly to metals, plastics, glass, and painted surfaces.
Flexible & Conformable
This self-adhesive copper foil bends and wraps around curves, corners, and complex shapes without tearing. It cuts cleanly with scissors or a knife, so custom widths and shapes are quick to produce.
Solderable Surface
The copper face accepts standard solder for permanent joints when needed. For temporary or field repairs, the conductive adhesive alone provides a dependable electrical connection.
Applications of Double Sided Conductive Copper Foil Tape
Conductive copper foil tape is used across electronics, manufacturing, education, and craft industries wherever electrical continuity or shielding is required.
EMI & RFI Shielding
Line equipment enclosures, guitar cavities, amplifier chassis, and device housings to suppress electromagnetic and radio frequency interference.
PCB & Circuit Repairs
Bridge broken traces on printed circuit boards, repair damaged flex circuits, and restore continuity to worn conductive paths without soldering.
Grounding & ESD Control
Establish low-resistance ground connections and dissipate electrostatic discharge to protect sensitive semiconductors and assemblies.
Cable & Connector Shielding
Wrap cable splices, connectors, and shielded cable ends to maintain shield continuity and reduce signal leakage in RF and data systems.
Paper Circuits & STEM Projects
Build LED cards, interactive posters, wearable electronics, and educational prototypes with easy-to-apply conductive copper tape.
Stained Glass & Crafts
Wrap glass edges for soldering in stained glass panels, suncatchers, and decorative metalwork projects.

How to Choose the Right Copper Foil Tape
Single-Sided vs. Double-Sided Conductive Copper Tape
Single-sided copper foil tape uses a non-conductive adhesive and conducts electricity only on the exposed copper face. It works well for stained glass, general wrapping, and shielding applications where contact occurs on one side only. Double-sided conductive copper foil tape conducts through both the foil and the adhesive, so every overlap and bonded surface maintains electrical continuity — essential for grounding through stacked layers and reliable EMI shielding.
When Conductive Adhesive Matters
Choose double-sided conductive copper tape when your design depends on electrical contact at every seam, overlap, or bond point — for example, connecting shielded enclosures, grounding through taped joints, or repairing circuit traces where the tape must bridge two conductive surfaces. If electrical performance is not required and the tape serves a decorative or moisture-barrier purpose, standard adhesive copper foil may be sufficient.
Frequently Asked Questions About Copper Foil Tape
Is double-sided conductive copper foil tape solderable?
Yes. The copper surface accepts standard rosin-core solder with a typical soldering iron. The conductive adhesive also forms an electrical bond on its own, while soldering adds a permanent mechanical joint for high-vibration or long-term installations.
What is the difference between conductive and non-conductive adhesive copper tape?
Conductive adhesive copper tape allows current to flow through the glue layer, so overlaps and contact points remain electrically continuous. Non-conductive adhesive copper tape insulates at the glue line and conducts only on the copper surface, which is suitable for crafts and one-sided shielding but not for through-bond grounding.
Can copper foil tape be used outdoors?
Copper naturally resists corrosion and performs across a wide temperature range. For extended outdoor use, apply the tape to a clean, dry surface and consider sealing the edges in highly humid or salt-air environments.
Does conductive copper tape stick to plastic and glass?
Yes. The acrylic pressure-sensitive adhesive bonds well to clean metal, plastic, glass, acrylic, painted surfaces, paper, and most smooth substrates. Wipe the surface free of dust, oil, and moisture before applying for the strongest bond.
How should I apply copper foil tape for the best conductivity?
Clean and dry the surface first. Press the tape firmly along its entire length, paying special attention to edges and overlaps. Avoid stretching the tape during application, and burnish overlaps firmly to ensure full contact between the conductive adhesive and the surface below.
