While all of this might be fine and dandy to the casual environmentalist, the maniacal, Captain Planet costume-wearing treehugger would point to the fact that if these bags are so evolved, why is the E in “evolve” lowercase and why don’t they have powers like the characters on Heroes?
A level-headed (not crazy) treehugger who doesn’t dress up in tights and paints their skin blue would probably wonder why Ziploc didn’t do more, since most of their bags probably end up in landfills and are difficult to recycle because they’re made out of #4 plastics.
The Ziploc evolve bags seem like a step in the right direction, but it would be more impressive if all of their bags were made this way.
The bags are available in sandwich ($2.49), quart ($3.49) and gallon ($3.49) sizes.
