Figuring out what fabrics can be safely used to sew leak-proof re-usable food packaging for lunchboxes and backpacks is challenging. Vinyl? I don’t think so. Oilcloth? It’s a vinyl. Laminated cotton? Well, I used it to sew my babies’ diapers, but I don’t know if I’d actually want them licking it, if you know what I mean.
The genius behind this mylar snack bag tutorial from French Sleep Deprivation Study is the choice of material. The mylar that you use is an upcycled chip bag. It’s not plastic, it is leak-proof, and we already know that Frito-Lay, at least, considers it food-safe. It’s a great alternative to wrapping your sandwich in vinyl.
