Production and Application Prospects of TRADSARK Metallized BOPP Film

Production and Application Prospects of TRADSARK Metallized BOPP Film

I. Overview of TRADSARK Metallized BOPP Film

Metallized BOPP Film is a composite film produced by depositing a micro-thin aluminum layer (typically 50-100 nanometers thick) onto a biaxially oriented polypropylene (BOPP) film through vacuum metallization. This process retains the high mechanical strength, chemical resistance, and transparency of BOPP while endowing it with excellent barrier properties, gloss, and electromagnetic shielding via the aluminum layer. As an industry leader, TRADSARK redefines packaging standards through innovative technology and superior quality.

II. Production Processes and Technical Status

(A) Core Production Processes

1. Base Film Preparation
   TRADSARK produces BOPP base films via biaxial stretching (longitudinal and transverse), strictly controlling thickness (15-20μm typical), flatness, and mechanical strength (tensile strength MD≥140MPa, TD≥250MPa, per GB/T 1040.3 standards) to ensure stability.
2. Vacuum Metallization
   Using imported German high-vacuum equipment (10⁻³-10⁻⁴Pa), aluminum wire is evaporated and uniformly deposited onto the base film to form a continuous aluminum layer (resistance ≤1.5Ω/□, per GB/T 15717 standards), with coating uniformity controlled within ±2% error.
3. Post-Processing
   Optional coatings (heat-sealant, antistatic, or food-grade ink) are applied to meet functional requirements for different scenarios (e.g., high-speed heat-sealing, precise printing registration).

(B) Technological Development Trends

1. Upgraded Barrier Properties
   • TRADSARK’s nano-coating technology (e.g., aluminum + silicon dioxide composite) reduces water vapor transmission rate (WVTR) to ≤0.2g/m²·24h and oxygen transmission rate (OTR) to ≤25cm³/m²·24h, meeting stringent standards for high-end pharmaceutical and electronics packaging.
   • Development of eco-friendly coatings (e.g., carbon nanolayers) to replace aluminum, reducing metal consumption and enhancing recyclability.
2. Green Production System
   • Solvent-free lamination processes eliminate VOCs emissions;
   • “Separable coating” technology enables efficient physical separation of aluminum and PP substrates, achieving a recovery rate of over 90%.
3. Smart Manufacturing
   • AI visual inspection systems monitor coating uniformity and film defects in real time, reducing defect rates to 0.05%;
   • IoT optimization cuts energy consumption in metallization by 25% compared to traditional processes.
