Is there any food grade epoxy resin?
No Although the epoxy resin itself is non-toxic, but due to the addition of solvents and other toxins in the preparation process, resulting in a lot of epoxy resin "toxic.".
In the past and the latest version of the national mandatory food additive standard GB2760-2014, has never included epoxy resin, so it does not matter what kind of food grade epoxy resin.
Of course, there are all major epoxy resin factories!
