Material Structure | 3-layer laminate: PET (outer layer, provides mechanical strength and printability) + Aluminum Foil (middle layer, barrier core) + PE (inner layer, heat-sealable) | |
FDA Compliance | Meets FDA 21 CFR standards for direct food contact, ensuring safety for protein powder and supplement packaging | |
Barrier Properties | - Oxygen Transmission Rate (OTR): ≤0.05 cm³/m²/day - Water Vapor Transmission Rate (WVTR): ≤0.1 g/m²/day (Blocks moisture, oxygen, and light to prevent protein degradation) | |
Heat Sealability | Inner PE layer enables strong heat seals (130°C–180°C); seal strength: 6–12 N/15mm (suitable for high-speed filling machines) | |
Customizability | Supports custom widths (150–1000 mm), lengths (500–3000 m), thicknesses (80–150 μm), and core sizes (e.g., 76mm/3") | |
Printing Compatibility | Up to 8-color flexographic or rotogravure printing; customizable logos/labels (e.g., QR codes, brand designs) | |
Applications | Primary use: Protein powder, sports nutrition supplements; also suitable for coffee, detergents, and pharmaceuticals |
