We have worked hard to find the very best food grade materials.
The clear viewing ends of the frames are made from a virgin food grade copolyester. The manufactures have assured us that it’s not only BPA-free, but it is not manufactured with bisphenol-S or any other bisphenol compounds. The manufactures also say that third-party labs have tested this material and the results have demonstrated that it is free of estrogenic and androgenic activity.
The Center frame parts are made from a Virgin Food grade Polypropylene which is also free from any Bisphenol compounds and is widely accepted as one of the safest plastics for food contact. It has also been used for many years in beehives for both Brood and Honey combs.
We will keep you informed if we have to use any different materials.
