My first Z-wraps were to see if I might reduce some of the single-use plastics (specifically, plastic wrap) in the kitchen. WELL, let me tell you, I RARELY used plastic wrap any more, instead opting for Z-wraps. If I have something particularly messy (Like PB&J) I might use a paper line, but all of my storage covers for plates, pots, and pans and Z-wraps. I haven't bought a box of plastic wrap since my first purchase, two years ago!
