Romania is the only European country to use polymer notes.
For 2 years now it’s been on polymer: https://www.ecb.europa.eu/euro/banknotes/europa/html/index.e...
I'm genuinely interested to see how the logistics of rolling out a new material will work across such a large area with so many countries and banks involved
The old 10€ bills stopped showing up in the change I got from stores by end of 2015, and around march 2016 the old 20€ bills stopped showing up.
Obviously, they’re still in use in several places.
And regarding the rollout: Most banks have had to accept dozens of possible payment methods, for them one more type of bills is not an issue. Producing the money is more of an issue, but the link I mentioned before has an article about that, too.
I don't live in the Eurozone, but I have a new and old €20, and the paper is the same. I have an old €50, and a new €5, and the paper is the same.
Polymer notes almost always have transparent windows, and they feel like plastic, not paper.

Are you sure you have actually gotten one of the new €20 notes?
Polymer notes like those I've used from New Zealand and Vietnam have the whole thing made from plastic, and no paper at all. Example: http://banknote.ws/COLLECTION/countries/ASI/VIE/VIE0124.htm
See, for example, http://www.reuters.com/article/us-euro-fakes-idUSBREA0C0JQ20... I can find no mention anywhere of polymer Euros.
That counts as plastic money, IMO.
