Polyester Film Laminated Aluminum Foil is available in a wide range of colors and can be produced in different sizes according to your requirements. We produce double-sided laminated foils, triple-laminated foils, and five-laminated foils that form a complete moisture barrier to prevent moisture, dust, and dirt from entering the insulation. In addition, we can provide foil laminates without adhesive layers to meet your specific needs.



Unlike metals, shielding laminates are non-conductive at their core. While metals such as copper are inherently conductive, shielding laminates formed from non-metals are ideally suited for use as insulation or signal shielding materials that do not respond to electric fields and resist the flow of charge.

Shielding laminates consist of at least two materials whose combined performance exceeds that of their individual components. In our context, we refer to shielding laminates consisting of both metals and non-metals, usually involving a combination of PET, PP, PI, PPS, PTFE with metals such as copper and aluminum.

Films laminated aluminum foil with hot melt adhesive are divided into two types: aluminum/PE shielding films and aluminum/PVE shielding tapes. They use MQ-40 high-molecular-weight polymer as heat-sealing glue, which is non-toxic and eco-friendly and complies with the latest version of the EU RoHS environmental regulations. The other type is self-adhesive film laminated aluminum foil, which uses genuine EAA self-adhesive film, ensuring good heat-sealing bonding effects at lower preheating temperatures and long-term stability.

Copper/PET shielding tapes is primarily used in various fields, such as extremely fine coaxial wires, low-loss antennas (computers), solar cell wires, etc.
