Roll-to-Roll Vacuum Coating Equipment

Technology Overview

Working Principle

• 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.

Key Advantages

1. Mass Production Efficiency: Deposition speeds up to 100 m/min with minimal material waste.
2. Cost-Effectiveness: Reduces labor and energy costs compared to batch processes.
3. Functional Versatility: Supports barrier coatings, conductive layers, and decorative finishes.
4. Sustainability: Enables lightweight, recyclable packaging solutions.

Applied Industries

• 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.

Coating Effects & Colors

• Surface Finishes: Metallic mirror finishes, matte textures, or holographic effects.
• Color Options: Customizable via reactive deposition (e.g., transparent blue for solar control).

Structure Types

• 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.

Substrate Materials

• PET, PP, aluminum foil, paper, and textile fabrics.

Coating Materials

• Metals: Al, Cu, Ag for conductive layers.
• Oxides: SiO₂, Al₂O₃ for barrier coatings.
• Polymers: Plasma-polymerized films for adhesion promotion.

Supporting Production Lines

• Integrates with online inspection systems (e.g., thickness sensors) and converting processes (e.g., slitting, rewinding).

Consumables

• Targets (sputtering), evaporation sources (Al wire), and inert gases (Ar, N₂).

Applications

• Packaging: High-barrier films for shelf-life extension.
• Flexible Electronics: Touch sensors and thin-film batteries.
• Architectural Films: Energy-efficient window coatings.
