BOPP Metallization Base Film - Dual-Side Heat Sealable with Single-Side Corona Treatment for High-Speed Aluminum Coating

Our BOPP Metallization Base Film is engineered specifically for vacuum aluminum deposition, featuring dual-side heat sealability and single-side corona treatment (≥42 dynes/cm) for superior metal adhesion. This high-barrier base film delivers exceptional dimensional stability during metallization processes while maintaining low seal initiation temperatures (100-120°C) for downstream packaging conversion.

• Optimized for Metallization - Surface roughness Ra ≤0.08μm for mirror-bright aluminum layers
• Dual-Side Seal Capability – 5-8 N/15mm  seal strength on both surfaces
• Precision Corona Treatment – 42-46 dynes/cm - on deposition side only
• Low Thermal Shrinkage – <1% @ 150°C – for stable web handling
• High Metal Adhesion – ≥3.5 N/15mm  - (ASTM D3359 cross-hatch test)

• 30% Higher Aluminum Yield – Ultra-smooth surface reduces metal waste
• Process Stability | Web tension tolerance ±5% for continuous deposition
• Post-Metallization Benefits – Maintains sealability for laminated structures
• Compatible with All Vacuum Systems – Leybold, Applied Materials, ULVAC

• Proven on 2.8m Wide Coaters – Consistent thickness profile (±1.5% cross-web)
• No Pre-Treatment Needed – Corona remains stable for 90+ days
• Sustainable Option – 30% PCR content available without performance loss
• Technical Support – Free metallization trials with your aluminum sources

To ensure the longevity and performance of our BOPP film, please adhere to the following guidelines:

• Shelf Life: 6 months from the date of manufacture.
• Storage Conditions: Store in a cool, dry place away from direct sunlight and moisture.
• Temperature Range: 10°C - 30°C.
• Humidity: Keep below 60% relative humidity.
• Handling: Avoid folding or creasing the film to prevent damage.
