PET Resin Properties for Pharmaceutical Packaging
Polyethylene Terephthalate (ANIMAL DE COMPAGNIE) has become the material of choice for pharmaceutical packaging due to its exceptional combination of mechanical, thermal, and barrier properties. This technical analysis examines the critical material characteristics that make PET suitable for drug packaging applications.
Key Material Specifications
- Intrinsic Viscosity (IV): 0.70-0.85 dL/g for blow molding applications
- Glass Transition Temperature (Tg): 70-80°C (ASTM D1525)
- Tensile Strength: 48-55 MPa (ASTM D638)
- Young’s Modulus: 2.8-3.2 GPa
- Oxygen Transmission Rate (OTR): 6-10 cc·mil/100in²·day·atm at 25°C
Pharmaceutical Compliance Standards
- FDA 21 CFR 177.1630 – Polyethylene terephthalate
- USP Class VI biological testing
- EP 3.2.2 Materials based on polyethylene terephthalate
- ISO 15378:2017 Primary packaging materials for medicinal products
Technical Advantages
PET bottles provide excellent chemical resistance against pharmaceutical solvents, alcohols, and aqueous solutions. The material demonstrates negligible interaction with active pharmaceutical ingredients (APIs), ensuring drug stability throughout the shelf life.
