Introduction
The rapid expansion of biosimilars has increased the demand for safe, stable, and efficient packaging systems particularly for injectable and protein-based formulations. Selecting the right packaging material is crucial, as it influences product stability, purity, and patient safety. This mini-review explores the scientific challenges associated with polymer and glass packaging for biosimilars, highlighting key risks such as delamination, protein aggregation, and extractables.

Understanding the Packaging Challenges for Biosimilars
Biosimilar formulations are sensitive to environmental and material-related stress. Poor packaging selection can trigger reactions such as oxidation, aggregation, or structural instability in protein-based drugs. According to global medical standards, organizations like the World Health Organization (WHO) emphasize the importance of ensuring safe pharmaceutical packaging that does not compromise drug quality or therapeutic impact.
Key Factors Contributing to Glass Delamination
Glass has traditionally been used for vials, prefilled syringes, and cartridges. However, certain conditions significantly increase delamination risks:
- High-pH formulations containing citrate or phosphate buffers
- High alkali content in glass materials
- Elevated temperatures during vial-forming
- Terminal sterilization processes (e.g., 20–40 kGy irradiation)
- Long storage durations and high product temperatures
These conditions cause surface layer peeling within glass containers, potentially leading to particulate contamination.
Further Reading and Resources
To minimize risk and enhance product stability, scientists recommend several preventive measures:
- Siliconization or surface treatment with ammonium sulfate
- Choosing appropriate glass specifications based on product pH
- Using COC/COP vials as polymer alternatives
- Opting for aluminosilicate glass instead of borosilicate
- Considering alternative sterilization methods only when necessary
Polymer Packaging: Emerging Solutions
The current market increasingly favors polymer-based systems like COC (Cyclic Olefin Copolymer) and COP (Cyclic Olefin Polymer) due to their chemical inertness and structural reliability.
However, challenges remainespecially regarding syringe lubricants. Silicone coatings, while helpful, can disturb protein stability. Excess silicone droplets may interact with proteins, causing unwanted aggregation. New fluoropolymer coatings offer smoother surfaces and better inertness, reducing these risks.
Extractables and Leachables: A Critical Evaluation
Extractables and leachables remain a major concern for inhalers, catheters, injectors, and wearable delivery devices.
The article provides equations to determine AET (Analytical Evaluation Threshold), helping scientists quantify risk associated with device components.
A detailed analysis of these calculations can be found in our main journal article, available at the official site.
Broader Implications in Biomedical Packaging
The U.S. Food and Drug Administration (FDA) highlights that robust packaging systems are essential to maintain drug sterility, prevent material interaction, and ensure safe delivery. This aligns with industry-wide efforts to adopt advanced polymers, fluoropolymer coatings, and precision-engineered delivery systems.
