Looking for Supplier of Butter Storage Bags?

We pre-cut our butter in 33lb blocks and store them in food safe, 20"x18"x26" 1.5mil plastic, 1 time use bags. Our issue is that they have been losing their integrity and have become a foreign matter hazard. I have been trying to find replacement bags that are stronger and maybe even colored, but I cannot seem to find a supplier that carries them. Does anyone know where I might find something like this?

They've got them in blue and pretty much any thickness you want. When looking for a local supplier try searching for "box liners food contact", that will help isolate the type of material you're looking for.

You try Uline for food contact wrap?

I looked forever, and right after I posted this I found some box liners in blue that will hopefully do the trick. I'm not confident about their thickness but they will be a step up from what we are using.
