If the general public didn't see retailers of high -value, small-size items, as a soft target for thievery and shoplifting, there wouldn't be any need for a big package with a small object.....and, yes, that's why you need a Stanley-knife to break-out the contents....too many empty packs on the shelves in earlier times.
I had about a 6foot high stack of clean, tape-free cartons they were pallet-size when flat.....council refused to take them unless I paid almost £20 for a skip....likewise clean, untorn, folded potato-sacks......gave many cartons to house-movers and bags to a local garden-centre....but a lot just went in the landfill-waste.
It is, indeed not a simple issue. Strangely, each year, there is a council list of the items which they can now recycle (but couldn't "yesterday") Coincidentally, they manage to meet the increased percentage of waste that's recycled,each year.
