I usually use a craft/stanley knife to cut bubble packaging, starting
by cutting up against the cardboard backing piece around the top of
the thing then across the bubble with a pair of scissors about two
thirds of the way up the packaging, in a lot of cases the packaging
can then be hung on the wall and used as a holder for what it
contained.

Apart from that there is far too much packaging used and no recycling
for a lot of the things, like thin tomato trays and other types of
very thin plastics.
