The memory map paper is just Tyvek, the stuff they make disposable suits, house and roof wrap out of. I've printed on Tyvek with an inkjet printer then crumpled it up and left it to soak in a glass of water for 10 mins - tear proof and waterproof straight off an inkjet printer. https://www.amazon.co.uk/Tyvek-105-1...YCEGGHBFZ01YFH
