The essential role of pharmaceutical packaging layers

Understanding the essential roles of primary, secondary, and tertiary pharmaceutical packaging is key to building resilient, compliant supply chains. At Swiftpak, we specialise in secondary and tertiary packaging solutions that support these layers, combing ISO-certified processes with bespoke, application-specific designs. With deep expertise in protective materials, temperature control and transit testing, Swiftpak helps pharmaceutical manufacturers and distributors meet stringent industry demands while optimising efficiency, sustainability and cost, even for the most sensitive medicines, vaccines and biologics.

In this blog, we will explain the types of pharmaceutical packaging and discuss the key benefits including safety, security and sustainability. We will guide you through overcoming common challenges in pharmaceutical packaging and provide some practical solutions that can be adopted in the pharma industry.

Types of pharmaceutical packaging explained

Pharmaceutical packaging is typically structured in three distinct layers, each designed to fulfil a specific function in protecting products and ensuring safe delivery through the supply chain.

1. Primary packaging

This is the first layer and comes into direct contact with the pharmaceutical product. This includes items such as blister packs, vials, ampoules and bottles. Its main purpose is to protect the medicine from contamination, moisture, light and air while maintaining product stability and efficacy.

Primary packaging also carries essential consumer and regulatory information, such as dosage instructions, expiry dates and batch numbers, making it critical for patient safety and compliance.

2. Secondary packaging

Secondary packaging surrounds the primary pack and provides an additional layer of protection during handling, storage and retail distribution. Common examples include cartons, sleeves and protective inserts.

This layer helps prevent damage, supports product identification, and often consolidates multiple primary packs for easier handling. It also plays an important role in tamper evidence and traceability throughout the distribution process.

3. Tertiary packaging

This packaging is designed for bulk handling, storage and transportation. This outer layer includes solutions such as transit boxes, pallets, protective cushioning and stretch wrap.

Its primary role is to secure pharmaceutical products during shipping, protecting them from impact, vibration and environmental changes while reducing the risk of tampering or theft. Effective tertiary packaging is essential for maintaining product integrity during long-distance or temperature-controlled distribution.

Key benefits: Safety, security and sustainability

Effective pharmaceutical packaging is fundamental to protecting products, patients, and supply chains. By combining robust materials with intelligent design, the right packaging solutions deliver measurable benefits across safety, security and sustainability.

Key benefits include:

• Enhanced safety and product protection: Pharmaceutical packaging prevents contamination and protects medicines from physical damage, vibration and environmental exposure throughout storage and transit. The use of robust materials such as engineered foams, cushioning and temperature-controlled solutions helps maintain product stability, particularly for sensitive drugs and vaccines.
• Improved security and counterfeit prevention: Well-designed secondary and tertiary packaging reduces the risk of tampering, theft and counterfeiting. Secure pack designs, combined with tamper-evident features, help safeguard product integrity and support traceability across complex pharmaceutical supply chains.
• Increased sustainability and operational efficiency: Modern pharmaceutical packaging supports sustainability goals through the use of recyclable and responsibly sourced materials. Optimised packaging designs reduce excess material, improved transport efficiency and lower overall carbon emissions. This helps businesses balance regulatory compliance with environmental responsibility.

Practical solutions from Swiftpak

Swiftpak delivers tailored secondary and tertiary pharmaceutical packaging solutions designed to meeting the exacting demands of pharma distribution, particularly for high-value and temperature-sensitive products.

• Advanced temperature-controlled protection: Swiftpak offers a range of temperature-controlled packaging options, such as Thermopak, to safeguard sensitive drugs throughout transit. Solutions such as stepped foam inserts provide precise cushioning and insulation, while vegan liners and Paperplus ® Papillon paper-based void fill help maintain thermal stability and protect against shock. These materials are carefully selected to support product integrity without compromising on sustainability.
• ISTA-certified bespoke packaging designs: All Swiftpak solutions are developed using ISTA-certified testing standards, ensuring packaging performs reliably under real-world transport conditions. Bespoke designs are engineered to fit products precisely, reducing material usage, minimising damage risk and lowering overall shipping costs. This approach is especially critical to patient safety and regulatory compliance.

Overcoming pharma packaging challenges

Pharmaceutical packaging must meet complex and often competing demands, from strict regulatory compliance to the growing pressure of e-commerce distribution. Swiftpak helps businesses overcome these challenges through custom-engineered, rigorously testing packaging solutions.

Meeting regulatory and security requirements

Swiftpak designs pharmaceutical packaging solutions that supporting regulatory compliance while incorporating effective tamper-evident features to protect product integrity.

Custom, tested designs ensure medicines remain secure throughout the supply chain, addressing the increased handling and transit risks associated with direct-to-patient and e-commerce delivery models.

Driving efficiency and reducing environmental impact

By leveraging advanced machinery and precision engineering, Swiftpak creates space-optimised packaging designs that maximise load efficiency and reduce material waste.

These efficiencies translate to lower shipping volumes, improved operational performance and reduced carbon footprints, helping pharmaceutical businesses achieve both cost savings and sustainability goals without compromising protection.
