Sustainable cold chain packaging: the overview for 2026
Short answer: the sustainable alternatives to EPS cooler boxes in 2026 are honeycomb insulated boxes (100% recyclable through the waste paper stream, comparable insulation value), paper insulation sheets, reusable EPP boxes for return systems and container liners made of recycled material. For the most sustainable image, choose honeycomb with FSC cardboard. For a return system, choose EPP with reusable gel packs.
Sustainability is no longer an option but a requirement. Customers, regulators (PPWR) and competitors are all putting pressure on the packaging sector to make environmentally friendly choices. This is the overview of the options, with, for each option, when it fits and what to watch for.
The problem with traditional EPS
EPS (expanded polystyrene, also known as styrofoam or Tempex) has been the standard for cold chain packaging for decades. The performance is excellent, the price is low. But there are disadvantages:
- Not biodegradable
- Recycling requires specialist processing
- Often made from virgin raw materials
- Negative image among end consumers
- Some countries levy taxes on its use
An honest picture is part of the story. EPS is lightweight and insulates well, so little material is needed per shipment. You can read how to have EPS processed after use in disposing of and recycling polystyrene foam.
Sustainable alternatives that we supply
1. Honeycomb insulated boxes
100% recyclable cardboard with a honeycomb structure. Comparable insulation value to EPS, fully recyclable through the regular paper stream.
- FSC-certified cardboard possible
- Fully circular-proof
- Attractive appearance for brands
- Sturdy and stackable
2. EPP cooler boxes (reusable)
EPP (expanded polypropylene) is more sustainable than EPS because it can be used repeatedly. Suitable for return systems. It only works if the boxes really do come back. Without a return flow, you lose the advantage. You can read more about the difference in choosing EPS or EPP.
3. Container liners made of recycled materials
For large shipments by sea container or pallet transport: thermal liners made of partly recycled material.
4. Conditioned gel packs (reusable)
Instead of disposable cooling elements: choose reusable gel packs that customers can send back or reuse via a return system.
Which do you choose?
| Need | Recommendation |
|---|---|
| Most sustainable image | Honeycomb + FSC cardboard |
| Return system | EPP + reusable gel packs |
| Budget more important than image | EPS (recyclable via a specialist route) |
| Industrial transport | Container liners (recycled) |
Questions you can ask beforehand
A good choice starts with your own situation. Go through these questions:
- How long is the route? For longer routes, insulation counts for more than the material. Always test whether the alternative holds your temperature.
- Does the packaging come back? If so, reusable pays off. If not, recyclable matters more.
- Who receives the shipment? A consumer often prefers paper. A company sometimes has a return system.
- What are the storage costs? Boxes take up space. Ask about dimensions and stacking options.
- What weight class does the shipment fall into? The weight of the packaging counts towards transport costs.
Practical pitfalls
- Choosing on the material alone. Packaging that does not hold the temperature leads to spoilage. That is the worst outcome for the environment.
- Not testing. Put a data logger in a trial shipment and see whether the temperature curve suits your product.
- Mixed materials. A box with plastic film or tape on it cannot always be recycled entirely through the paper stream. Ask about the composition.
- Box too large. Less air in the box means less material and less cooling mass. See choosing the right box size.
Legislation and regulation: PPWR
The European Packaging and Packaging Waste Regulation (PPWR) affects how packaging is designed and processed. What exactly that means for your shipment depends on your product and your market. You will find more information on our page PPWR packaging regulation. If in doubt, check the current text or ask for advice.
EPS is sometimes still the best choice
Sustainable does not always mean a different material. Sometimes the best choice is a well-fitting EPS box that keeps cool long enough and thereby prevents food waste. Our EPS boxes come from our own production since 1972. You will find a comparison in EPS boxes vs honeycomb cooler boxes.
Frequently asked questions
Does honeycomb insulate as well as EPS?
According to our product information, the insulation value is comparable. The actual holding time depends on the design, the outside temperature, the fill and the cooling elements. Test for your route.
Can I also use EPP boxes as single-use packaging?
You can, but the advantage of EPP lies in reuse. Also take a look at the reusable EPP boxes.
Are there reusable options for pallets?
Yes, for example reusable thermal pallet covers. Read more on our page reusable thermal pallet covers.
