PRACTICAL – LIGHTWEIGHT – COST-EFFECTIVE – FUNCTIONAL
Arguments that convince!
The idea is as simple as it is convincing: why use heavy, bulky zinc coffins when the Foliensarg | BioSeal offers the same function?
This innovative coffin made of tear-resistant metal foil can be securely sealed using a special foil sealing device, which is available in several versions and can even be operated via the vehicle’s cigarette lighter. The special film is supplied on rolls that are customised according to the customer’s wishes. We calculate an average of 4.2 metres for a deceased person.

The Foliensarg | BioSeal revolutionises the transfer and storage of deceased persons: cost-efficient, hygienic and sustainable. Originally developed by NASA for space research, the BioSeal metal composite film provides a hermetic seal without odour or liquid leakage and significantly reduces flight costs thanks to its low weight. Flexible adaptation to any coffin shape, quick application and easy disposal make it an advanced alternative to the zinc coffin. Confirmed by renowned institutes and proven in international applications – discover the advantages of the foil coffin!
Your advantages at a glance:

Hermetic seal for absolute hygiene
The Foliensarg | BioSeal guarantees a 100% airtight and liquid-tight seal. Odours and liquids cannot escape when used properly – a seal that has been confirmed in a comprehensive experiment conducted by the German Armed Forces’ climate chamber.

Time-saving and easy handling
With a sealing time of just 2-3 minutes, the foil coffin | BioSeal can be handled quickly and easily – far quicker than conventional zinc coffins that require time-consuming soldering.

Flexibility: Suitable for every coffin model
The mouldable BioSeal film fits into any coffin, regardless of its shape. In contrast, zinc coffins with their rigid shape are only compatible with specific coffin models. For undertakers, this means that they can offer their entire range without being restricted to specific models.

Environmentally friendly and easy to dispose of
At the destination, the film can be easily removed and disposed of in an environmentally friendly manner. It can be incinerated and leaves virtually no residue – confirmed by an expert opinion from the Fraunhofer Institute for Process Engineering and Packaging.

Reduced risk of accidents and injuries
As no hazardous materials such as hydrochloric acid, soldering irons or gas cylinders are used for sealing, the risk of accidents is completely eliminated. There is also no risk of “coking” in the coffin.

No pressure equalisation valve required for air transfers
Thanks to its stability, the hermetically sealed film coffin | BioSeal does not require an additional pressure equalisation valve, which confirms its suitability for air transport. The German Armed Forces have successfully tested the stability and adaptability of the film in the climate chamber.

Mobile use thanks to car adapter
The BioSeal film coffin can be used flexibly and is usually dispatched within 24 hours. A car adapter makes the system ideal for demanding locations.

Time-saving closure with resealing option
Once sealed, the film can be opened and resealed at any time, which further simplifies practical use.

Cost-effective and transport-efficient
The Foliensarg | BioSeal is a far more cost-effective alternative to conventional zinc coffins. In addition, the low weight of the film significantly reduces transport costs for air transport.

X-ray capability of the metal composite foil
In contrast to the zinc coffin, the Foliensarg | BioSeal is radiolucent, a practical advantage confirmed by the Institute of Forensic Medicine at the University of Heidelberg.

Low storage and space requirements
The film is supplied on rolls to save space. A roll of e.g. 105 metres corresponds to approx. 25 zinc coffins. This significantly reduces storage space and logistics costs.
The BioSeal film coffin sets new standards in hygienic, flexible and economical storage and transfer and offers funeral directors as well as forensic and pathological institutes a modern, adaptable and affordable solution. The special film is available on rolls, the length of which is customised according to customer requirements.
