Polymers: PET, PP, PVC, PEN (thickness: 8–100 μm)
Metals: Aluminum foil, copper foil (thickness: 5–50 μm)
Composites: Carbon fiber-reinforced polymer (CFRP) tapes, glass fiber fabrics
Silver:
Materials: Aluminum (Al) film (thickness: 50–100 nm) or silver (Ag) film (20–50 nm).
Features: High reflectivity (>85% for visible light), bright metallic sheen. Al is cost-effective; Ag offers higher reflectivity (used for high-end applications like LED reflectors).
Applications: Food packaging (metallic PET films), decorative labels, automotive interior trims.
Gold/Bronze:
Materials: Titanium nitride (TiN, 50–80 nm) or alloy films (Al-Cu, Al-Zn).
Features: TiN films exhibit a gold color (due to interband transitions in the material); Al-Cu alloys produce bronze hues (Cu content: 5–15%).
Applications: Decorative hardware (door handles, watch cases), electronic connectors (gold-plated Cu foils for corrosion resistance).
Copper-Red:
Materials: Pure copper (Cu) film (30–60 nm).
Features: Natural reddish metallic color, high electrical conductivity. Susceptible to oxidation (requires a protective topcoat like SiO₂).
Applications: Flexible circuit boards (Cu-coated PET), decorative crafts.
Clear (Colorless):
Materials: SiO₂ (50–200 nm), Al₂O₃ (30–100 nm), ITO (100–200 nm).
Features: High light transmittance (>85% for visible light); SiO₂/Al₂O₃ act as moisture barriers; ITO combines transparency with conductivity.
Applications: Touchscreen glass (ITO coatings), food packaging (clear barrier films), solar cell covers (anti-reflective SiO₂).
Tinted (Blue/Green):
Materials: Metal oxide films with controlled thickness (e.g., TiO₂-SiO₂ multi-layers, 100–300 nm).
Features: Color arises from light interference—thinner films (100–150 nm) appear blue; thicker films (200–300 nm) appear green.
Applications: Optical filters (camera lenses), architectural glass (heat-reflective tinted films).
Rainbow Iridescence:
Materials: Multi-layer films (e.g., SiO₂-TiO₂-SiO₂, each layer 50–100 nm thick).
Features: Light interference across different layers produces a shifting rainbow effect (angle-dependent color).
Applications: Cosmetics packaging, security labels (anti-counterfeiting), decorative textiles.
Matte Metallic:
Materials: Metallic films (Al/Ag) with a micro-rough surface (achieved via substrate texturing or post-deposition etching).
Features: Dull metallic finish (gloss level: 10–30 GU) with reduced reflection, avoiding glare.
Applications: Automotive instrument panels, smartphone back covers (matte silver).
Products: Metalized PET/PP films (for food packaging), barrier films (for pharmaceuticals), decorative packaging films.
Key Requirements: Oxygen transmission rate (OTR) <1 cc/(m²·day), moisture vapor transmission rate (MVTR) <0.1 g/(m²·day) (to extend shelf life).
Example: Flexible food pouches (e.g., coffee, snacks) use Al-metallized PET films (50 nm Al layer) to block oxygen and light—extending product shelf life from 3 months to 12+ months. R2R machines produce these films at 15–20 m/min.
Products: Flexible circuit boards (Cu-coated PET/PEN), transparent conductive films (ITO/PEDOT:PSS), RFID antennas (Al/Ag-coated films).
Key Requirements: High conductivity (Cu films: <5 Ω/sq), film flexibility (10,000+ bending cycles without cracking), low defect rate.
Example: Foldable smartphone displays use Ag nanowire-coated PET films (deposited via R2R magnetron sputtering) — these films maintain 90% conductivity after 100,000 folding cycles (radius: 1 mm).
Products: Solar cell films (SiNₓ passivation layers, anti-reflective SiO₂ films), fuel cell gas diffusion layers (GDLs with Pt coatings), lithium-ion battery current collectors (Al/Cu foils with anti-corrosion coatings).
Key Requirements: High light transmittance (SiO₂ films: >95% for 400–800 nm), corrosion resistance (battery foils: <0.1 mm/year in electrolyte).
Example: Thin-film solar panels use R2R PECVD to deposit SiNₓ layers (100–150 nm) on flexible glass substrates—improving cell efficiency by 2–3% via reduced surface recombination.
Products: Anti-reflective (AR) films (for eyeglasses, screens), polarizing films (for LCD displays), LED reflectors (Ag-coated films).
Key Requirements: AR films: <1% reflectivity (visible light); polarizing films: >99% polarization efficiency.
Example: Laptop screens use multi-layer AR films (SiO₂-TiO₂, deposited via R2R thermal evaporation) — reducing glare from 8% to <1%, improving user comfort.
Products: Anti-UV textiles (TiO₂-coated fabrics), conductive textiles (Ag-coated non-wovens), self-cleaning fabrics (TiO₂-coated cotton).
Key Requirements: Wash durability (50+ washes without film peeling), flexibility (compatible with fabric stretching).
Non-Stop Operation: Unlike batch-type vacuum coaters (which require loading/unloading between batches), R2R systems enable 24/7 continuous production. For example, a 1.3 m-wide R2R machine can produce 50,000 m of metalized PET film (used for food packaging) per 8-hour shift—3–5x more efficient than batch systems.
Scalable Web Width: Industrial models support web widths from 0.5 m (lab-scale) to 2.5 m (large-format applications like solar panels), adapting to both R&D and mass production needs.
Dimensional Precision: Vacuum deposition minimizes air molecule interference, achieving film thickness uniformity of ±1–3% (vs. ±5–10% for atmospheric coating). For transparent conductive films (e.g., ITO), sheet resistance variation is <5% across the entire web.
Low Defect Rate: In-vacuum pre-treatment and closed-loop tension control reduce film defects (pinholes, scratches, bubbles) to <0.1 defects per m²—critical for electronics and optical applications.
Substrates: Handles flexible, roll-form materials including:
Polymers: PET, PP, PVC, PEN (thickness: 8–100 μm)
Metals: Aluminum foil, copper foil (thickness: 5–50 μm)
Composites: Carbon fiber-reinforced polymer (CFRP) tapes, glass fiber fabrics
Coating Materials: Supports metals (Al, Ag, Cu, Au), metal oxides (SiO₂, TiO₂, ITO), nitrides (SiNₓ, TiN), and organic films (polymer barriers via PECVD)—covering functional needs from conductivity to corrosion resistance.
Vacuum System Optimization: Turbo-molecular pumps (energy consumption: 0.5–2 kW) replace traditional diffusion pumps (5–10 kW), reducing energy use by 60–70%. Heat recovery from cooling systems further cuts energy costs.
Material Utilization: Magnetron sputtering achieves 70–90% target material utilization (vs. 40–60% for thermal evaporation), lowering raw material waste. For high-cost materials (e.g., silver), this translates to 30%+ cost savings.
