What kind of products could you pack?

Food and cosmetic products are our main targets.

What is really unique in your technology?

Together the very high water vapor barrier (low Water Vapor Transmission Rate – WVTR) and the % of cellulose after treatment (from 99 to 99,9% depending on the treated materials).

How do we get these new properties for papers or boards?

Thanks to an alumina layer that wraps any single cellulose fiber at the surface of the treated material. The alumina layer is only few nanometers thick!

Does your final product contain any trace of plastic?

Our product is plastic free, only cellulose and ceramic (alumina).

How is the end of life affected?

The end of life is not affected. Materials will remain as recyclable, compostable and naturally degradable as pure cellulosic materials are.

What kind of process is it?

We use a technology very familiar to microelectronic companies: ALD (Atomic Layer Deposition), which is a thin-film deposition technique based on the sequential use of a gas-phase chemical process.

Is it possible to keep traces of this gas or liquid on the coated paper?

The process design and the nature of the materials grant that there is absolutely no trace of the chemical material consumed for the coating.

What about the food contact compliance?

Alumina is already identified within Commission Regulation (EU) No 10/2011 on plastic materials and articles intended to come into contact with food.

Is there any nanoparticles in your coating?

Our coating has nothing to do with nanoparticles. It is a cohesive layer, chemically bonded to cellulose. The thickness of this layer is few nanometers.

How Cilkoa modifies the feeling of the paper?

Paper touch is not modified. Transparency is also kept intact.

Is the technology able to process large quantities within short leadtime?

Yes. Our technology is based on a compact batch process. Each production unit is able to process full rolls (no need to unroll) our entire pallets of trays in a few hours. Depending on the required production rate, the sizing of industrial facilities is very modular and compact. For example, to process 50 million B5 trays per year, we need a few cubic meters of equipment.
