I can buy frozen vegetables and fish at the supermarket, which are packaged only in paper boxes (no plastic inside). For example : https://www.vomar.nl/g-woon-Tuinerwten-Extra-Fijn-450-g

Not sure about the EU market, in the US most paper or cardboard packaging for use with frozen or refrigerated foods is hard to recycle[1].
