Product Attributes Table​

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.

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
