Barrier Data: Why Aluminum Foil Three Side Seal Bags Excel
Compare actual oxygen and moisture transmission rates across common laminate structures used in three side seal pouches. Our aluminum foil bags provide near-zero permeability — critical for extending shelf life.
| Material Structure | Oxygen Barrier (OTR)* | Moisture Barrier (WVTR)* | Light Block | Typical Use |
|---|---|---|---|---|
| Aluminum Foil (PET/AL/PE) | ≤0.05 cc/m²·day | ≤0.05 g/m²·day | 100% | Coffee, milk powder, pharma, chemicals |
| Metallized (PET/VMPET/PE) | 0.5-1.0 cc/m²·day | 0.5-1.0 g/m²·day | 99% | Snacks, dried food, pet treats |
| Clear High-Barrier (SiOx-PET/PE) | 1.0-2.0 cc/m²·day | 1.0-2.0 g/m²·day | 0% (Transparent) | Display products, short shelf life |
| Kraft Paper / PE (no foil) | 5.0-10.0 cc/m²·day | 2.0-5.0 g/m²·day | 100% | Dry herbs, low moisture items |
*OTR measured at 23°C, 0% RH; WVTR at 38°C, 90% RH. Lower = better barrier.
Our custom three side seal foil bags can be engineered with any of these structures. Add a zipper, tear notch, or hang hole to match your filling line and consumer needs.
