Vacuum-Metallized Aluminum Layer vs. Conventional Aluminum Foil: A Comparison of Environmental Performance and Properties
Thickness Difference

Vacuum-Metallized Aluminum Layer: Nanometer scale (30–50 nm), about 1/200 the thickness of conventional aluminum foil.

Conventional Aluminum Foil: Minimum thickness of 6 micrometers (6,000 nm), with high aluminum resource consumption.

Manufacturing Process and Structure

Vacuum-Metallized Aluminum: Aluminum molecules are deposited onto paper under vacuum conditions. Does not form an independent film, achieving strong adhesion with the paper.

Conventional Aluminum Foil: Produced by rolling into an independent film, then laminated to paper in a separate process.

Biodegradability

Vacuum-Metallized Aluminum Layer:
✅ Breaks down along with paper, dispersing as nanoparticles with no impact on soil degradation processes.
✅ Minimal aluminum usage makes environmental residue negligible.

Conventional Aluminum Foil:
❌ Stable film structure resists degradation; long-term soil residue may inhibit microbial activity.

Application Benefits

Lightweight: Saves aluminum resources and reduces transportation costs.

Flexibility: Nano-layer maintains paper flexibility, supporting complex packaging designs.

Conclusion
Vacuum-metallization technology, with its nanometer-level aluminum usage and non-film properties, achieves high barrier performance while ensuring full environmental biodegradability. It is a sustainable solution to replace conventional aluminum foil.
