There's something instinctual that tells me it isn't going to work with pre-shredded packaged kale, but I can't articulate a guess as to why - or whether that's even accurate. Cell wall deterioration, excess moisture, incipient decomposition, ???? I'm assuming you did make sure that the leaves were in a single layer with good separation between them so the air could circulate.
I've never heard of rainbow kale either, though it would surprise me that chard would be chip-able
since the leaves are so delicate and moist. I might have to try chard chips. Leaves of root beets are tougher than leaf beet (chard) ... might try that too.
I haven't tried it again since we talked about kale chips the last time and I mentioned that I always have an issue with some (sometimes most) of the chips coming out very bitter. I wonder now whether it's because I didn't get them completely coated with oil. Still, I've had enough fails that at this point I consider it a waste of good kale - which is one of my favorite vegetables.
