As supply chains come under increasing pressure to reduce waste and emissions, materials such as high-recycled-content corrugated board, fibre-based solutions and bio-derived alternatives are moving from niche to mainstream. This shift is being accelerated by tighter regulations such as Extended Producer Responsibility (EPR), growing customer expectations for sustainable logistics, and the need for more efficient, space-optimised palletisation.
For businesses, tertiary packaging is no longer just about protection in transit, it’s a strategic opportunity to cut carbon, improve operational efficiency and strengthen environmental credentials. While primary packaging at the primary level focuses on individual products, the difference with tertiary packaging lies in its main purpose, protecting goods at scale during storage and transport. Sustainable materials now deliver the durability, load stability and double-pallet compatibility required by modern logistics, while supporting circular economy goals.
In this blog, we explore how these materials are transforming tertiary packaging choices, the benefits they bring across the supply chain, and how Swiftpak is helping organisations transition to more sustainable, future-ready solutions.
What are sustainable materials for tertiary packaging?
Sustainable materials for tertiary packaging are designed to protect goods during bulk handling, storage and transport while reducing environmental impact. When assessing the different types of sustainable tertiary materials available, several key factors, such as strength, weight, recyclability and cost, determine the most suitable packaging solution.
Unlike traditional plastic stretch films, foams and void fillers, these alternatives prioritise recyclability, renewable inputs and circular use, without compromising on performance or logistics efficiency.
Key options include:
- High-PCR corrugated cardboard: Manufactured with a high percentage of recycled fibre, it offers excellent compression strength and load stability for palletised goods. It is commonly used to produce robust cardboard boxes, shipping boxes, pallet collars and layer pads. These boxes support secure stacking and compatibility with double pallet utilisation across distribution networks.
- Bio-based films: These are another emerging solution, produced from renewable resources such as plant starches or cellulose. These films can be used for pallet wrapping or load containment, delivering comparable stretch, tear resistance and transparency to conventional plastic films while reducing reliance on fossil fuels.
- Mycelium foams: These are grown from fungal networks and agricultural by-products. They provide a natural alternative to expanded plastic foams. They offer excellent shock absorption and cushioning for heavy or fragile goods, ensuring each piece of packaging protects loads during transit while being fully compostable at end of life.
- Fibre-based paperisation solutions: These replace plastic components with reinforced paper and moulded fibre formats. These materials can be engineered to deliver high-load bearing capacity, abrasion resistance and dimensional stability, enabling effective pallet protection and secure handling. Their lightweight nature also supports efficient double pallet utilisation without adding unnecessary mass.
Together, these sustainable materials demonstrate that tertiary packaging can achieve the strength, protection and supply chain compatibility required for modern logistics, while significantly reducing environmental impact and maintaining product integrity to a high standard.
