It's made out of PUL, which is a type of plastic used to make diapers often. I know PUL isn't FDA approved for food, but there's also lots of debate whether or not plastic baggies and ziplock bags are really food safe too. Pretty much it seems like a no win battle, I think. So we end up wrapping the loaf of bread in a cheese cloth and popping it in this bag so it keeps the air out. At least we're not throwing plastic away...but there needs to be more food safe, air tight options in my opinion.
On a positive, the design works perfect! The bottom is 6 inch square. The 4 sides are 16 x6 inch rectangles. I sewed it up, leaving the top side open. I turned the top side over and hemmed. There's a soft side 3 inch velcro midway on the bag. There's a1 inch scratchy velcro on the opposite side of where the soft side velcro is, placed on the hem. You can fold over twice to securely close the bag, so it's air tight. Sometimes I can fit 2 loaves of bread in it and freeze it.
