Non sticky packaging

We all know the problem with ketchup or mayonnaise: 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: The leftovers first have to be removed from the packaging, which is expensive, time-consuming, and uses a great deal of water. If the products inquestion are pharmaceuticals, chemicals or pesticides, the rinsed-out leftovers also have to be disposed of in a suitable manner. This could all be a nuisance of the past very soon. Researchers apply thin films, no more than 20 nanometers thick, to the inside surface of the packaging. “We make the coatings from a plasma of the type already familiar from neon lamps,” explains IGB scientist Dr. Michaela Müller. “It is done by placing the plastics into a vacuum. We introduce gases into this vacuum chamber and ignite them by applying a voltage. We 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.”

Nice to read? does it have any relation with product viscosity?

Comment by Sadanand Manurkar

off course it will. Thicker fluids (higher viscosity) will stick to the packaging more than liquids with a lower viscosity. This is true for al materials. But this packaging will ‘stick’ less than any other. As a mater of fact it almost doesn’t.
