Yep: National Trust annual kilo-through-the-post.
Heavily printed with the message, in the now-familiar ticking-off school-marmish tone: "Do not put in your recycling. Put in your compost." [1][2]
The substance caused me to finger it in a kind of wonder, perhaps as a caveman might have handled a cashmere sweater: what _is_ this strange substance? How was it made? How can it be "potato starch", when it feels so much like tough polythene? [These are all rhetorical questions chaps: I don't care to know.]
I also noticed that it seemed to be a patented product, made in Austria. So what's the "carbon footprint" for that, then, Mr Clever-Clogs NT?

[1] I use "school-marmish" in the old fashioned sense: I'd be quite surprised if any teacher has dared to be actually bossy, or even authoritative, in the last decade or so. [2] And secondly, having almost mastered the art and science of putting the right things in the right bins over several years years, many people will undoubtedly carefully place this wrapper into the rubbish bin, thinking it to be polythene. Will the recycling police call round?! 8-O
