Functional Packaging in Pharmaceuticals: An Overview

Functional packaging in pharmaceuticals serves a dual purpose: it protects products from external elements and promotes safety and ease of use for the consumer. Specialist healthcare packaging addresses specific challenges in pharmaceutical storage and distribution.

  • Blister packs provide unit dosing and protect the product from moisture and contamination.
  • Bottles shield from light and desiccants are included to combat moisture, preserving product integrity.
  • Tamper evident parts offer a visible indication of product safety, ensuring the consumer receives the product as intended.
  • Child-proof design to prevent access to medicines

The choice of materials in functional packaging ranges from barriers that protect against moisture and oxygen to UV-protective packaging that shields the product from harmful light exposure can be complete by active solution as desiccant, equilibrant, oxygen scavenger, or volatiles.

Prioritizing Product Stability and Safety

Functional packaging is key in maintaining the stability of pharmaceutical products. It plays an indispensable role in preserving the product’s integrity, preventing reactions that could alter the drug’s composition and efficacy.

Beyond chemical stability, the physical protection of pharmaceuticals is a central concern. Packaging is carefully designed to prevent damage during transportation and handling, ensuring that the product reaches the consumer in perfect condition.

Safety is paramount, and functional packaging addresses this through child-resistant designs, tamper-evident features and easy to handle features

Through meticulous design and material selection, functional packaging guards’ pharmaceutical integrity, playing a critical role in maintaining product stability and ensuring safety across the pharmaceutical supply chain.

Overcoming Environmental Factors

The ongoing effort to protect pharmaceutical integrity from environmental threats is relentless, and functional packaging is essential in addressing key areas: humidity, dryness, oxidation, light, and temperature.


Humidity is a notable challenge with the potential to jeopardize product stability. Functional packaging addresses this issue by integrating desiccants to absorb excess moisture and employing moisture barrier coatings to prevent ingress. The reverse, a low level of humidity, can also affect the mechanical properties of drug product, as dryness can make the product brittle.


The oxidation of a drug product can lead to product degradation, compromising its efficacy and safety. This process may result in changes to the drug's organoleptic characteristics, such as color modification, affecting its overall quality. Effective measures to prevent oxidation are crucial in maintaining the stability and integrity of pharmaceuticals.


UV light, too, poses risks, particularly for photosensitive pharmaceuticals. The industry’s response includes opaque and tinted packaging materials, designed to safeguard against UV and visible light exposure.


Temperature fluctuations, encountered during global distribution, demands robust packaging materials and innovative design, ensuring product stability across diverse climatic condiditons.

Ensuring Compliance and Adherence

Functional packaging plays a critical role in compliance within the pharmaceutical industry. Regulatory bodies across the globe have stringent requirements packaging to ensure product safety, stability, and efficacy. Functional packaging helps healthcare manufacturers meet these requirements through:

  • Child-resistant packaging: This design prevents children from accessing potentially harmful medications, contributing to safety.
  • Easy handling: Designs make packaging easy for elderly patients to handle and open
  • Tamper evident features: Visible signs to indicate if the packaging has been compromised, ensuring product integrity.

By meeting these needs pharmaceutical companies contribute to a more secure medication distribution system, reducing risks of contamination, tampering, and accidental ingestion.  

Packaging can also include:

  • Unit dosing: This helps in managing medication regimens, particularly for chronic conditions requiring long-term medication.
  • Clear labeling: Providing clear instructions and information on the packaging ensures patients understand how to take their medication correctly.

Enhancing User Experience

However, functional packaging extends beyond safety; user experience holds significant importance, and functional packaging plays a pivotal role in this context. Pharmaceutical packaging should offer an intuitive and user-friendly design, guaranteeing that patients can access and administer their medication with ease and clarity.

Key elements in enhancing user experience include:

  • Ergonomic design: Packaging that is easy to handle and open improves the user experience, especially for elderly patients or those with limited dexterity.
  • Information accessibility: Clear and concise labeling ensures that patients have access to the information they need to take their medication safely and effectively.

By prioritizing the user experience, pharmaceutical companies help to ensure that patients and caregivers can manage their medications confidently and independently.
