I bought multiple colors in these bags, for cookies. At first they looked good, no bleeding through. Then after a day or so in the bags, the grease started to run through. You can see it went through the baggie itself, and then the label that goes on each cookie. Very disappointed with this product, really wanted it to work out because they are nice looking. Wish I could get a refund for the ones I got, but because we used them, I don't think that's possible. Not greaseproof, think before purchaSee full review
