- About
Aluminum foil shielding tape is typically constructed from aluminum foil laminated with polyester film (PET), creating a composite material that balances electrical shielding with mechanical strength. This structure is often referred to as aluminum–polyester tape (AL/PET). As a critical form of aluminum foil tape for EMI, it plays an essential role in maintaining signal integrity in data, communication, and power transmission applications. Its ability to block external interference makes it indispensable in modern high-speed and high-frequency systems.
The aluminum layer provides effective aluminium foil shielding by reflecting and absorbing electromagnetic and electrostatic noise, while the polyester film reinforces tensile strength and electrical insulation. Depending on application requirements, the tape may be supplied with or without adhesive and in single-sided or multi-layer configurations.
Aluminum Foil Shielding Tape is manufactured using one or more layers of aluminum foil bonded with polyester film using high-performance adhesives such as oven-cured polyurethane. This laminated structure enhances durability while preserving excellent EMI shielding effectiveness.
Available constructions include:
These configurations allow customization based on shielding level, cable type, and production processes.
Deyou polyester-laminated aluminum foil tape can be produced in various thicknesses, widths, and colors to meet specific application and identification requirements.
As a high-performance EMI shielding aluminum foil solution, the aluminum layer effectively blocks electromagnetic and electrostatic interference, protecting signal quality in sensitive electronic systems.
By minimizing noise and crosstalk, aluminum foil shielding tape ensures stable signal transmission in high-speed data and communication cables.
The polyester film layer improves tensile strength, tear resistance, and handling stability compared to standard aluminium foil tape.
Multi-layer laminated designs create an effective barrier against moisture, dust, and dirt, protecting cable insulation layers from environmental damage.
Available with or without adhesive layers, aluminum foil shielding tape can be easily integrated into various cable wrapping and manufacturing processes.
Aluminum foil tape for EMI is widely used in:
It enables both individual pair shielding and overall cable assembly shielding.
Aluminum foil shielding tape is applied in electronic devices and assemblies to protect sensitive components from electromagnetic interference and electrostatic discharge.
In environments where signal stability is critical, such as telecommunications and data transmission, EMI shielding aluminum foil solutions help maintain consistent performance.
Aluminum Foil Shielding Tape is an essential material for modern electrical and electronic applications requiring reliable EMI and ESD protection. By combining the conductive shielding properties of aluminum foil with the mechanical reinforcement of polyester film, it delivers effective aluminium foil shielding without compromising durability or flexibility.
Whether used as aluminum foil tape for EMI, aluminium foil tape in cable manufacturing, or a multi-layer shielding solution, This product provides dependable performance across a wide range of industries and applications.
