Product Description
High Barrier Tea Composite Roll Film
OTR ≤0.8 Cm³/m²·day | UV Blocking >90% | For Freshness Retention
Product Attributes
| Attribute | Description | Reference |
|---|---|---|
| Material Composition | Multi-layer coextruded or laminated structure (e.g., PET/AL/CPE, PET/EVOH/PE, or PA/AL/PP) with aluminum foil (6.5-12 μm) or metallized PET for enhanced barriers. | 7 13 |
| Oxygen Barrier (OTR) | Ultra-low OTR ≤0.8 cm³/m²*day (23°C, 0% RH) via aluminum/EVOH layers, preventing tea oxidation and preserving polyphenols. Complies with ASTM F1249. | 1 11 13 |
| UV Blocking | Blocks >90% of UV radiation (200-400 nm) using UV-absorbing additives or metallized layers, protecting tea from light-induced flavor degradation. | 3 9 13 |
| Moisture Barrier | WVTR ≤1.5 g/m²*day (38°C, 90% RH) via aluminum foil (≥7 μm) or PVDC coatings, maintaining tea moisture content at 3-5%. | 11 13 16 |
| Aroma Retention | Prevents aroma loss and external odor contamination through high-density molecular barriers and inert gas flushing (N₂/CO₂) during sealing. | 11 13 |
| Thermal Stability | Withstands -20°C to 120°C, suitable for hot-fill tea bags, retorting (121°C sterilization), and frozen storage. | 11 13 |
| Safety Compliance | FDA 21 CFR, EU 10/2011, and LFGB certified for direct food contact; BPA-free and heavy metal migration below 0.01 ppm. | 7 18 19 |
| Printability | Corona-treated surface (≥38 dyne/cm) supports high-resolution rotogravure/flexo printing (≤10 colors) for brand customization. | 7 13 |
