Metalized BOPP Film (VMBOPP) is a composite material formed by vacuum-depositing a 0.01–0.1 micron aluminum layer onto BOPP film. The process involves vaporizing aluminum under high vacuum to create a lightweight, flexible layer that combines BOPP’s durability with aluminum’s barrier properties. Core Traits Barrier Performance: Blocks oxygen, moisture, and UV light, ideal for food packaging (e.g., snacks, baked goods) to extend shelf life. Cost-Effective Lightweighting: Weighs 1/5 of aluminum foil, cutting costs by 30–50% while enabling easy lamination. Processing Versatility: Supports glossy/matte finishes, high-speed printing, and heat-sealing for automated packaging lines.
