PP bottles — Polypropylene packaging for the pharmaceutical and medical sectors

Polypropylene: The Material of Choice in the Pharmaceutical Industry

PP (recycling code No. 5 — PP) is a semi-crystalline thermoplastic characterised by its exceptional lightness (the lightest of all common plastics, with a density of 0.90) and its superior heat resistance, which can reach 120–130°C in continuous use. This property makes it suitable for steam sterilisation processes (autoclave).

PP offers excellent resistance to acids, alkalis and polar solvents, making it the material of choice for aggressive pharmaceutical formulations and veterinary products. It complies with USP Class VI requirements for medical applications and with GMP standards for pharmaceutical manufacturing.

Technical Properties of Polypropylene (PP)

Advantages of PP bottles

• ✓Maximum thermal resistance — Withstands temperatures up to 120°C in continuous use — the only commonly used autoclavable plastic.
• ✓Suitable for steam sterilisation — Can be autoclaved at 121°C without warping. Ideal for pharmaceutical and medical packaging.
• ✓Excellent chemical resistance — Excellent resistance to acids, alkalis, alcohols, ketones and hospital cleaning products.
• ✓Lightest material — Density 0.90 — PP helps reduce the weight of packaging and the carbon footprint of transport.
• ✓Pharmaceutical compliance — USP Class VI grades available, compliant with GMP requirements for the manufacture of medicines.
• ✓Certified for food contact — Approved for contact with foodstuffs and food supplements.
• ✓Excellent impact resistance at low temperatures — When additives are added, PP retains its mechanical properties at low temperatures (for use in refrigeration).
