If you know where to find this kind of plastic, please share!
They're a Russian company organized in Estonia. I did a quick search of the USPTO, Estonian and Russian patent databases and that didn't turn up any of the inventors' names nor the name of their company "Magnetic IP OU."
If you're interested in licensing their technology, which they claim is patented, I'd be happy to liaise with them on your behalf through their American office. Let me know!
Based on what I can see, it appears to be BOPP film. I have used this film in food label applications where a durable waterproof material is required. We routinely had issues with the static properties of this material. I would look at samples of this material and compare it to the material Tesla Amazing is using.
