Those seem to be made of the same thing (polyvinyl alcohol) anyway?
I think Earth breeze reduces the need for the plastic outer packaging. There’s alot in the Liquid and the Pods.
I remember my Granny fussing about the powder as opposed to the liquid. She had many complaints, too much plastic was not one of them. Set in her ways.
Seems to me that if they are in the form of sheets, they’re using much more polyvinyl alcohol per unit of detergent than the pods, which are closer to spherical.
