For years, expanded polystyrene (EPS), commonly known as styrofoam, has been the default material for temperature-sensitive transport. Lightweight, insulating and inexpensive, it seemed ideal. But logistics chains across sectors are now moving away from EPS. The reasons are clear: limited recyclability, increasing regulatory pressure, and the shift toward more compact, circular packaging systems. Sustainable alternatives are gaining traction in food logistics, floral transport, pharmaceuticals, and seafood distribution.
Why EPS is Losing Ground
EPS is difficult to recycle, bulky to handle in reverse logistics, and prone to breakage and waste. Many European countries are introducing restrictions on the use of single-use EPS packaging. Additionally, major retailers and logistics providers are pushing for reusable or fully recyclable packaging that aligns with their sustainability goals.
For cold chain applications, where stable temperatures are essential, this means new solutions are required, ones that perform just as well without the environmental drawbacks.
Cardboard and Recyclable Insulation
A growing number of cold packaging systems are combining sturdy cardboard boxes with insulating liners made from recycled fibers, foam, or paper composites. These alternatives offer sufficient thermal protection for shipments lasting several hours or up to a full day, depending on the type and number of cooling elements used.
Their advantage lies in end-of-use processing. Cardboard can be recycled through standard waste streams, and many liners are either reusable or easy to replace. The packaging volume also collapses significantly when empty — making storage and return logistics far more efficient.
Reusable Systems and Modular Use
For longer shipping distances or closed-loop distribution environments, reusable cooling boxes and modular units are emerging as practical solutions. These are built from layered insulating materials and often sized to fit standard transport containers or trolleys.
Companies using fixed distribution patterns benefit from reduced packaging waste and lower operational costs. Integrating reusable cooling mats or phase-change materials ensures that internal temperatures are maintained over long periods — without the need for active cooling.
From Concept to Implementation
Suppliers like interfreshconcepts.com are at the forefront of this shift, offering a wide range of environmentally responsible packaging solutions. From recyclable boxes to lightweight cooling pads, their portfolio supports sectors where performance and sustainability must go hand in hand. Their systems serve fresh flowers, perishable foods and seafood — including air freight packaging designed for reuse or recycling.
By aligning packaging materials, cooling methods and logistics processes, businesses can meet strict temperature requirements while cutting down on waste and improving supply chain efficiency.
