Food grade/safe plastic or fabric, any suggestions?

PUL and oil cloth are not food safe. A lot of folks suggest items...but most are not food safe. Now if you are not going to put food directly into the bag and just want to make it water proof...then yes anything will do...but I personally would want my lining to be food safe...so there is no leeching into my food.

Note what I found from a seller of oilcloth saying that it can not be used.

Can I sell stuff that I make out of oilcloth?
There is no lead in the oilcloth, but the levels of Phthalates are too high to comply with the new standards for items which are going to be sold and are intended to be used by children under 12 years old. So you can still make and sell bags and other things created with oilcloth but items like bibs and splat-mats cannot be sold.

SnackTAXIs are lined with a waterproof material that consists of nylon with a polyurethane coating. After talking to many manufacturers of this product, we understand that this type of coated nylon is free of heavy metals and phthalates. We have found a supplier of this coated nylon who has had their product extensively tested. The tests revealed that the nylon is free of heavy metals (including lead), phthalates, PBBs, and PBDEs. We will be ordering all of our nylon from this supplier going forward.
I think I will be using Rip Stop only for the waterproofing and add a note for buyer to decide how best to pack their food items in the bag :)

I have done alot of research on this. PUL manufacturers say it is NOT food safe. Oil cloth is not good. But polyurethane coated nylon pack cloth has a long established roll in food safe bags for the outdoor sports folks. It is also the material being used by the major manufacturers of reusable sandwich bags. It is important to note that the coated side of the nylon is faced away from the food. So if you are going to make these, fact the shiny coated side to the wrong side of your outer fabric. This also helps to guard against outside moisture from getting into the food. I have more of this on my blog: firstname.lastname@example.org
