No matter how we shake or tap the bottle, some of the content refuses to come out. In some cases, up to 20 percent is left in the packaging when it is dumped in the trash can. This is not only annoying for consumers, but also poses difficulties when recycling. If the products are pharmaceuticals, chemicals or pesticides, the rinsedout leftovers also have to be disposed of in a suitable manner. Thin films, no more than 20 nanometers thick are applied to the inside surface of the packaging. It is done by placing the plastics into a vacuum. The gases are introduce into this vacuum chamber and ignite them by applying a voltage. Different coating can be deposit with defined properties on the surface of the packaging, depending on the proportions of electrons, ions, neutrons and photons in this luminous gas mixture.
