Aluminum foil polyester film for cables is a composite material commonly used in cable manufacturing. It consists of layers of aluminum foil and polyester film bonded together by means of adhesive or thermal bonding.

Aluminum foil polyester film for cables usually consists of three main parts: an aluminum foil layer, a polyester film layer, and an adhesive layer. The aluminum foil layer provides the shielding function of the cable and can effectively block external electromagnetic interference. The polyester film layer provides mechanical strength and insulation to protect the internal conductors of the cable. The adhesive layer is used to bond the aluminum foil layer to the polyester film layer.

When it comes to Aluminum Foil Polyester Thin for Cables Aluminum Foil Polyester Thin for Cables is mainly used for the shielding and insulating layers of cables. It can be applied to various types of cables, including communication cables, power cables, control cables, coaxial cables and so on. According to the specific application requirements, different thicknesses and specifications of aluminum foil polyester film can be selected.


As the shielding layer of the cable, the aluminum foil layer can effectively block the electromagnetic interference from the outside. It can reduce the interference of internal signals of the cable and the interference of external signals to the cable, and improve the quality and stability of signal transmission. Aluminum foil polyester film for cables is particularly important in the field of communication and data transmission because it protects signals from interference and distortion.

The polyester film layer has good insulating properties that isolate wires and other cable components, preventing current leakage and short circuits. It provides sufficient electrical isolation to ensure safe cable operation.

Between the aluminum foil and the polyester film, an adhesive layer is usually required to ensure a strong bond between them. The selection and use of adhesives is critical to the performance and reliability of aluminum foil polyester film. Common adhesives include glues or thermal adhesives.

Aluminum-foiled polyester films typically have good corrosion resistance to a number of common chemicals and environmental conditions. This helps protect the internal components of the cable from damage caused by the external environment.

Aluminum foil polyester film for cables is easy to process and apply. It can be cut, coiled and joined according to specific cable design requirements. In addition, it can be used in combination with other cable components such as insulation, jacketing, etc. to meet the overall design needs of the cable.
