Have picked up 4 sheets this afternoon, it does not say what the outside coating is but it is quite hard and has a satin sheen finish so I assume it is plastic not paper. When I enquired at the till if the girl( woman) knew what the material was I was greeted with the response:' no one has ever asked me that before!' I won't have the opertunity to 'play' with the sheets for a few days but will post if and or when I have had a chance to investigate further, I thought it was well worth a 'punt' , you get a lot of material for a tenner .
