The rise of hygroscopic APIs (e.g., montelukast sodium) and biologics demands next-gen packaging. Cold aluminum blister (PET/AL/PET) offers a breakthrough solution, combining aluminum’s barrier properties with cold-forming efficiency. Learn how this technology outperforms traditional PVC/PVDC.
Core Advantages of Cold Aluminum Blister Packaging
1. Military-Grade Barrier Performance
✓ Oxygen Blockade:
OTR ≤0.05 cm³/m²·day (vs. 0.8 in PVC) – extends shelf life to 3+ years
✓ Moisture Fortress:
WVTR ≤0.1 g/m²·day – protects hygroscopic meds like gabapentin
✓ UV Defense:
Metalized PET blocks 99.9% light – prevents photodegradation
Validation Data: After 36mo @25°C/60%RH:
Potency retention: 98.7% (cold aluminum blister) vs. 91.2% (standard blisters)
2. Production-Area Friendly Cold Forming
✓ Zero Thermal Stress:
Forms at 22-28°C (vs. 180°C for thermoforming) – ideal for probiotics & vaccines
