Single Side Aluminum Foil Composite Tape
AL PET Shielding Tape for Communication and Data Cable
Product Overview
What This Product Is
Single side aluminium foil composite, usually called AL/PET tape, is a soft aluminium foil bonded to a polyester film. It is produced by intaglio coating, slitting and rolling, and it is the everyday shielding wrap in communication, data, coaxial, internet and signal cable. The polyester layer carries the tensile load so the foil does not tear during taping, and the finished tape can also be cut for assembly-level shielding and grounding.

Key Benefits
What It Gives Your Production Line
Shielding Where the Field Is Magnetic
Designed for environments with magnetic fields and minimal electromagnetic interference or static discharge.
Foil Backed So It Does Not Tear
The polyester film supports the soft aluminium through the taping head at production speed.
Documented Attenuation Band
Effective in the 1 to 100 MHz range, reaching up to 70 dB shielding attenuation when used with Mylar foil.
Colour and Print to Order
Blue and silver are standard; red, green and gold are available, along with printing and printed twill.
Application Scenarios
Where It Is Used
- Shielding of communication and data cables
- Coaxial cable foil layer
- Internet and LAN cable shielding
- Signal cable shielding
- Assembly-level shielding and grounding after cutting to size
Who It Is For
Who Buys It
- LAN and coaxial cable plants running taping heads
- Signal and instrumentation cable makers
- Assembly shops cutting shielding tape to size
Problems It Solves
The Reasons Buyers Move To This Product
Bare Foil Tears at Speed
Unsupported aluminium splits in the taping head. The PET backing carries the tension instead.
Shielding Claims Need Numbers
The tape has a stated working band of 1 to 100 MHz and up to 70 dB attenuation with Mylar foil, so specifications can be written against real figures.
Colour Coding Across Product Lines
Several colours and printed options let you identify constructions on the factory floor.

Manufacturing And Quality Control
How It Is Produced And Checked
Materials are produced to the stated thickness, width and formulation, then slit, wound and packed to the reel or core size ordered. Dimensional checks are made against the specification before dispatch.
Incoming Material
Foil, film, compound or wire checked for thickness and surface condition before processing.
Processing
Coating, lamination, slitting or drawing to the ordered dimension.
Dimensional Check
Width, thickness and roll or reel diameter verified against the specification.
Performance Reference
Shielding attenuation and conductivity referenced to the published figures for the grade.
Packing
Shaft or reel packing in cartons for safe handling and transport.
Customisation Options
What Can Be Changed
- Colour: blue, silver, red, green, gold and others
- Printing and printed twill
- Slitting width to your taping head
- Coating for assembly-level shielding and grounding
Use Guide
Working With It On Your Line
- Keep the foil side facing the cable core so the shield contacts the drain wire.
- Set taping overlap to your construction spec and check it on a cut sample each shift.
- Store rolls flat and dry; a deformed roll edge feeds unevenly.
- Do not stretch the tape during application — tension thins the foil and lowers attenuation.

FAQ
Single Side Aluminum Foil Composite Tape FAQ
What frequency range does this tape shield?
It is designed primarily for EMI protection in the 1 to 100 MHz range.
How much attenuation can it achieve?
Up to 70 dB shielding attenuation when used with Mylar foil.
Which colours are available?
Blue and silver are the common colours. Red, green, gold and other colours can be produced, and printing or printed twill is available.
How is the tape manufactured?
By intaglio coating, slitting and rolling, which bonds the soft aluminium foil to the polyester film.
Can it be used for grounding?
Yes. With the appropriate coatings it can be used for assembly-level shielding and grounding after being cut to size.
