Functionalisation of Paper and Cardboard. How to make Paper/Cardboard impervious for packaging?

Paper and cardboard require functionalisation so that they can be used in contact with food. Functionalisation may include adding a barrier function to water, grease, gases, etc. This is mainly achieved through the use of plastic, i.e. the combination of polymer(s) + additive(s). Paper and cardboard
food packaging are therefore not free from plastic. As such, most paper and cardboard packaging remain at the same level as “single-use plastics”, as defined in the European Directive on Single-Use Plastics.
