PUL is NOT food-safe. I have looked at several different options and I have thought, what if you treated the one side of te fabric (nylon) and then put that side not upagainst the food? That way, its hidden, but still waterproof. Also thought why not use nylon, then a layer of fleece, then the layer of cotton?? I like snack baggies but my biggest reason for looking into this, is making freezer-safe bags. Tupperware just dosent do it for me (too $ and too bulky), and I dont want to use Ziplock. Im thinking if I treated one side of the fleece with beeswax and then layered it between nylon and cotton, that that would work?? What do you think??

My lowest oven setting is 200. Granted I was using leather not fabric but there was no fire.
I now have an updated tutorial here:
And also sell custom made ones here, for the less crafty:
The tutorial for making the cloth is very simple and there are lots of great patterns and tutorials all over the web for making the bags.
If you are looking at buying a handmade beeswax cloth sandwich bag, one or two really should be enough. I wash mine by hand in the sink (takes about 45 seconds) in cold water and it dries overnight. If you pack lunch in the morning, one is enough and if you pack it in the evening, two will do. Also, they should last for 1-3 years! We used ours 3-4 times a week last school year and it still looks brand new.
I tried re-posting my Beeswax Cloth tutorial link, but I don't think it worked, so here it is once more for good measure:
And my shop link for buying them if you're not crafty:
PUL is definitely not food safe. Little Moose Diapers has a good post on it, as well as Crafting a Green world. Plain cotton or beeswax cloth are the only good natural options I've come across. Everything else is petroleum based, just like a Ziploc or Tupperware.
This is a great thread. Thank you for the tips. I was looking into making a large bag that I can use for transporting rotisserie chicken (they always put them in those thick plastic bags with handles!) or other meat I buy at the store. The chicken is too large to put in the stainless steel container I usually bring to the butcher (to avoid plastic or paper wrapping).
I thought maybe I could make a large bag big enough for a rotisserie chicken, and coat it with beeswax or something else; and I guess a tie at top to close it. It would be less bulky/lighter than bringing a large container or pyrex.
Anyone think this is advisable? Would a warm rotisserie chicken just melt the wax? Help, please!
I would stay far far away from PUL food wrappers. The stuff off-gasses nasty chemicals and we avoided using it for diapers for that reason. Plastic bags are also considered "food safe," but plastic is what we're trying to avoid, isn't it? A word of warning regarding using linseed oil: "boiled" linseed oil contains heavy metals that help it dry faster. DO NOT use for food. You can get raw linseed oil which would be a safer option, but if you're wanting to use it for something that's going to come in contact with food it makes sense to use food grade oil. Flax oil is the same thing as linseed oil, but it's less processed. It will take forever to dry if you use it right out of the bottle, but if you heat it up to the point where it almost starts to smoke (careful! you can also use a thermometer: 180 degrees) it will hydrogenate the oil and make it dry faster. (I know we avoid hydrogenation in food, but that is what "drying" oils are doing when they dry, and it's a good thing when you're not ingesting it and want it to solidify in your cloth or as a wood finish.)
Personally, I vote for using glass, stainless, or enamel containers for most things. But there are situations where bags make more sense...
vanrey - I think a rotisserie chicken would melt the wax somewhat, maybe not making it unusable, but I would think that it would get chicken fat sort of mixing with the wax and maybe get a little funky after a while. But oil cloth would probably be a good bet. I don't have any experience with oil cloth, but we made an earthen floor in our straw bale house and sealed it with linseed and tung oil, and so I researched linseed oil a lot in preparation for that. Linoleum was originally made from a mixture of cork and linseed oil. When the linseed oil drys it's different than solidified wax. It really forms a plastic-like composite with whatever it's soaked into. I can't vouch for it's performance as a plastic bag substitute, but it certainly wouldn't melt.
