Roll-to-roll (R2R) vacuum coating is a continuous PVD process designed for high-throughput deposition on flexible substrates like plastics, metal foils, and paper. It combines vacuum evaporation, sputtering, or plasma-enhanced techniques to create functional films for packaging, electronics, and renewable energy applications.
- Continuous Substrate Handling: The substrate is unwound from a roll, passed through vacuum chambers for deposition, and rewound after processing.
- Vacuum Integration: Multi-chamber designs separate coating zones to prevent cross-contamination (e.g., sputtering for metal layers and evaporation for oxides) .
- Precision Control: Advanced tension and alignment systems ensure uniform film thickness (±2%) across the web.
- Mass Production Efficiency: Deposition speeds up to 100 m/min with minimal material waste.
- Cost-Effectiveness: Reduces labor and energy costs compared to batch processes.
- Functional Versatility: Supports barrier coatings, conductive layers, and decorative finishes.
- Sustainability: Enables lightweight, recyclable packaging solutions.
- Packaging: Metalized films for food and beverage containers.
- Electronics: Flexible circuits and OLED displays.
- Solar Energy: Transparent conductive oxides on PV modules.
- Automotive: Window films with UV/IR protection.
- Surface Finishes: Metallic mirror finishes, matte textures, or holographic effects.
- Color Options: Customizable via reactive deposition (e.g., transparent blue for solar control).
- Single-Chamber: Simplified design for basic coatings.
- Multi-Chamber: Segmented into pre-treatment, deposition, and post-treatment zones.
- In-Line Integration: Combines coating with printing or laminating processes.
- PET, PP, aluminum foil, paper, and textile fabrics.
- Metals: Al, Cu, Ag for conductive layers.
- Oxides: SiO₂, Al₂O₃ for barrier coatings.
- Polymers: Plasma-polymerized films for adhesion promotion.
- Integrates with online inspection systems (e.g., thickness sensors) and converting processes (e.g., slitting, rewinding).
- Targets (sputtering), evaporation sources (Al wire), and inert gases (Ar, N₂).
- Packaging: High-barrier films for shelf-life extension.
- Flexible Electronics: Touch sensors and thin-film batteries.
- Architectural Films: Energy-efficient window coatings.
