Are you asking what is bad about the cardboard, or what is bad about the box?

Nothing is wrong with the cardboard except weight. Nothing is bad about the box except for the remainder of unused space that is in almost every package (and filled with more expensive paper or inflated filler)

For a shipper, minimizing weight and wasted space is a double win. This product has nothing to do with what the consumer wants.

So its even more difficult to recycle than single-layer plastics and still of no use to anything too large for a padded envelope.

Well it's multipurpose. One roll can ship many different things. Otherwise you need an inventory of various sized boxes. I'm guessing it will find an instant niche.
