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?
