Why the Fiber Box
Keeps its shape for up to ten days
A transport box made from virgin paper fiber and industrial hemp: food-safe for fresh fish, built for the cold chain, stackable on the pallet — and at the recipient it goes into waste paper collection.
Water-resistant
Fish and ice in
Fully filled with fish and ice, the box keeps its shape and function at 0–2 °C and 90–95 % relative humidity — for up to 10 days. Tested food-safe and odor-neutral.

Stackable
Nested in — stacked out
Delivered nested to save space. Filled with fish and ice at your site, closed, stacked, loaded and on its way to the recipient — that is how it runs in daily operation.

In use
In daily operation at a major German fish wholesaler
The wholesaler supplies restaurants and retailers with fresh fish and seafood — and has used the Fiber Box in daily operation since 2026. This followed a test in live operation in February 2026: up to 10 days in the fresh fish cold chain at 0–2 °C and 90–95 % relative humidity, fully filled with fish and ice, repalletized several times and moved by pallet jack — plus a real truck delivery to the customer.
Every shipment. A new box.
Every delivery starts in a new box — tested food-safe, into waste paper collection at the recipient. Fresh fish on ice, hand picking, pallet, truck: that is how the wholesaler's daily operation runs. How it runs on your routes, the pilot will show.
Field test in live operation at the fish wholesaler: up to 10 days, long-term test over 15 days. Reported in FischMagazin 2/2026 · References on request.

What the Fiber Box delivers
Quantity, time, load, testing — the figures purchasing and quality assurance ask for.
You know the molding principle from the egg carton. Add to that pure virgin fiber, high fiber density and moisture resistance built into the fiber itself. Tested for direct food contact.

Internal long-term test without operational handling, February 2026
48 kg Top load
On the bottom box in the test: four filled boxes (5 kg fish and 3 kg ice each) plus two layers of extra weight — around 48 kg.

Built for the cold chain
The Fiber Box does not cool or insulate by itself. The cooling comes from the ice packed with the goods and the active refrigerated environment — the box carries and protects the goods in that environment. It is not designed for unrefrigerated shipping outside the cold chain.

Tested & award-winning
Your supplier approval is prepared
Food contact tested in a DAkkS-accredited laboratory. Production in Arnstadt certified by TÜV Rheinland to BRCGS Grade A. Recyclability assessed by the cyclos-HTP Institute.
Disposal with waste paper
The cyclos-HTP Institute assesses how far a package can be recovered in the existing paper cycle. For the Fiber Box, the test showed a potential fiber yield of 85 % — that much of the material can be reprocessed into pulp in the paper process. In addition, the box is assigned to waste paper grade 1.01.00, ordinary mixed paper. The test also covered conformity with the ZSVR minimum standard for assessing recyclability — the benchmark used in Germany to assess recyclability for packaging fees.
This defines the disposal route: clean and empty, the box goes into the waste paper collection that already exists at your site and at the recipient.

For purchasing & controlling
What a shipping unit really costs
The unit price is one item among several. Storage, delivery, packaging fees and disposal all count — calculate with your own quantities, routes and rates; we list the items with your quote.
Storage & transport
Four pallets, 720 complete boxes
240 boxes (Medium / base) per pallet, 720 lids per pallet — the molded parts nest to save space. Four pallets give you 720 complete Fiber Box Medium boxes.
5,760 complete boxes per full truckload on 32 pallets — delivered nested empty and stored the same way.
Packaging fee
Paper, paperboard and cardboard fraction
In your packaging declaration, the Fiber Box falls into the paper fraction. The fee depends on your rate and the weight.
In future, EPR fees are also to be graded by recyclability (Art. 6(8) PPWR). You will then document the classification of your packaging with a recyclability assessment — for the Fiber Box, it is available: cyclos-HTP, 85 % potential fiber yield.
Disposal
Via waste paper collection
Clean and empty, the box goes into waste paper collection — at your site as well as at your customers and recipients, back into the paper cycle.
