Against the backdrop of accelerated upgrading of the global catering supply chain, aluminum foil container have become the core packaging choice for the European and American takeaway markets and emerging catering services in Africa due to their excellent functionality, food safety, and environmentally friendly and recyclable characteristics.
As an expert in aluminum-based material manufacturing, we deeply integrate raw material aluminum foil rolls/strips/sheets, supply and terminal container manufacturing, providing global B2B customers with a full-link solution from basic materials to high-value-added finished products.
Characteristics of aluminum foil rolls
The quality of aluminum foil rolls directly determines the performance upper limit of the terminal container. We strictly follow international standards (ASTM B479, EN 546) to ensure that the raw materials have the following core characteristics.
Multi-dimensional barrier (experimental data support)
Table1:
| Parameters | Measured value | Performance impact |
| Water vapor transmission rate | 0.8 g/m²·24h (ASTM E96) | Humidity fluctuation zone shelf life increased by 40% |
| Oxygen transmission rate | 0.4 cm³/m²·24h·atm (ISO 15105) | Inhibits oil oxidation and rancidity |
| Ultraviolet blocking rate | >99% (280-400nm) | Prevents light-induced nutrient degradation |
Experiments at the University of Cape Town in South Africa show that the microbial proliferation rate of cooked food packaged in aluminum foil is 2.3 times slower than that of PP containers at 35℃/80%RH.
Precise control of mechanical properties

- Heavy metal migration is below the detection limit (Pb<0.01mg/kg, Cd<0.005mg/kg).
Aluminum foil container forming process
Core technology, servo direct drive high-speed stamping
- Stamping speed: 200-400 times/minute.
- Positioning accuracy: ±0.1mm.
- Mold life: ≥5 million times (chrome plating hardening treatment).
Five-step precision process
1 Laser calibration unwinding
eliminate material internal stress, flatness error ≤0.2mm/m.
2 Multi-stage progressive stamping
Pre-stretching → deep forming → side wall shaping (strain rate control ±2%).
3 Nano-level trimming technology

Core advantages of aluminum foil containersÂ
Functional advantage comparison (aluminum foil vs. plastic PP)
Table3:
| Indicators | Aluminum foil container | PP plastic container | Value difference |
| Oxygen barrier | 0.01 cc/pkg·day | 120 cc/pkg·day | Shelf life extended by 3 times |
| Temperature range | -40℃~250℃ | -20℃~120℃ | Suitable for oven/quick freezer |
| Thermal conductivity efficiency | 237 W/mK | 0.22 W/mK | Reheating time halved |
Economical evidence, African market case
Reduced food loss
- After fast food chains adopted it, the waste rate dropped from 12% to 5% (annual savings of $280,000)
Reduce overall costs
- Lightweight design (83% lighter than glass) → Logistics costs reduced by 22%
- No-cleaning process → Operational manpower savings of 15 FTE/year
Innovation and sustainable development
Technological breakthrough direction
- Ultra-thin and high-strength materials:Â The tensile strength of 0.05mm thick aluminum foil is increased to 215MPa (nanocrystalline strengthening technology)
- Smart manufacturing upgrade:Â Digital twin stamping line: Real-time simulation optimization parameters, the yield rate is increased to 99.2%
Circular economy practice
- Closed-loop recycling system
Carbon footprint reduction results
- The proportion of recycled aluminum application ≥50% → Carbon emissions are reduced by 92% compared with primary aluminum (LCA data)
- Lightweight design → Carbon reduction of 48 tons per million containers (EPD certification)
From high-precision aluminum foil rolls to intelligent stamping lunch boxes, we have built a full value chain capability for material science precision manufacturing and recycling. Provide environmentally friendly solutions that comply with EPR regulations for high-end markets in Europe and the United States, and create cost-effective leak-proof and antibacterial packaging systems for African customers.
