Rigid waterproof coating for paper aims to reduce our dependence on plastic

For our sake and the environment, there is a considerable amount of research into the reduction of plastic for many and various applications. Researchers have now found a way to imbue relatively sustainable paper materials with some of the useful properties of plastic. This can be done easily, cost effectively, and efficiently. A coating called Choetsu not only waterproofs paper, but also maintains its flexibility and degrades safely as well. https://www.sciencedaily.com/releases/2022/05/220513103505.htm
