Echo ClareBear; that strip across the top of cd cases also sets me to cussin'. Some are so 'glued' on that it is difficult to get them off without damaging the information labels.

Those 'clamshells' are often glued to cardboard and it is difficult to separate the two; where plastic and cardboard are supposed to be separated for recycling, the two never separate cleanly.

I keep a plastic bag near my printers, into which I put all the packaging as well as spent cartridges; at the computer store they have a big box for the recycled cartridges, I toss in packaging and all, let them complain.
Canon ink refills have a hard plastic gizmo over the delivery opening, if not removed carefully, ink spurts out.

Let's start a campaign to waterboard package designers!
