Does anyone know of a good food grade stencil material supplier. I have been doing research on the Internet for days and come up with conflicting reports on what is considered food grade. I contacted the Grafix Company and they said that only their acetate is considered food grade, (comes in tablet form on Amazon) but some people say that this material is not acceptable for stencils. Some culinary stencil sites say that they use food grade plastic or food grade Mylar, but I can't seem to find a supplier or source for these materials. Can anyone offer advice on how or where to proceed?
