Non-stick packaging

Shaking and tapping is often the only way to get the last drop of ketchup out of the bottle. But in future, even this final drop will slide out easily onto the barbecued steak - thanks to a special coating on the packaging.

The researchers apply thin films, no more than 20 nanometers thick, to the inside surface of the packaging. It is done by placing the plastics into a vacuum. They introduce gases into this vacuum chamber and ignite them by applying a voltage and can deposit different coatings with defined properties on the surface of the packaging, depending on the proportions of electrons, ions, neutrons and photons in this luminous gas mixture.
