Material Structure | 3-layer laminated composite: Biaxially-oriented polyester (BoPET) film + aluminum foil (7–9 µm) + heat-sealable polyethylene (PE) inner layer. Optimized for lightweight yet durable barrier protection. | |
Barrier Performance | Oxygen Transmission Rate (OTR) ≤0.05 cm³/m²·day; Water Vapor Transmission Rate (WVTR) ≤0.5 g/m²·24h (38°C, 90% RH). Blocks UV light and moisture. | |
Certifications | RoHS/REACH compliant (heavy metals ≤0.01 ppm); FDA 21 CFR compliant for indirect food contact. | |
Thickness | Ultra-thin 0.02mm (2 mil) design balances flexibility and strength, ideal for lightweight packaging. | |
Seal Design | 8-side heat-sealed edges ensure leak-proof integrity; compatible with impulse sealers (120–160°C). | |
Applications | Coffee, nuts, dried herbs, pharmaceuticals, and electronics requiring moisture/light protection. | |
