I feel like this is actually more costly for a company, as this would require a secondary machine to produce versus doing it all on one with the old metal tops.
Oh, is it a resealable tab? I've been staring at this picture for a while trying to figure out why anyone would think it was a good idea to replace the traditional aluminum tab with that. If that's the case I don't think these are going to catch on very widely outside of those oversized energy drink cans. Seems like an inferior design in every way otherwise.
