PET Metallized Film with Stainless Steel combines high mechanical strength and corrosion resistance with effective barrier performance against moisture and oxygen, making it well-suited for industrial packaging, flexible electronics, and EMI shielding. The stainless steel layer enhances structural integrity, while the PET film’s optical reflectivity contributes to thermal insulation and energy efficiency. This material is commonly used in food packaging to extend product freshness and in electronics for shielding sensitive components from electromagnetic interference. Researchers and engineers have used this film to for applications in high-performance laminates, multilayer barrier films, and energy-efficient systems, highlighting its role in enhancing functional properties for laboratory, engineering and industrial use.
