PET Metallized Film with 30 nm Aluminum Coil

Polyethylene Terephthalate (PET) Metallized Film with 30 nm Aluminum Coating (Coil/Roll) delivers controlled conductivity and moisture resistance for use in flexible electronics, barrier systems, and engineered thin-film applications. PET Metallized Film consists of polyester film coated with a thin layer of aluminum to make it reflective while still retaining the polyester's strength and flexibility. The aluminum layer is extremely thin at 30 nanometres, ensuring uniform surface behaviour suitable for electromagnetic shielding and conductivity testing. In laboratory and research settings, this film is used to prototype and evaluate flexible OLEDs, capacitors, and other thin-film devices. Its reliable adhesion and dimensional stability support advanced development in nanotechnology, electronics, and materials science where high-performance, flexible systems are required. Available in a variety of coil widths and lengths.
