PlanetBox identifies the exact tray as at least 91% recycled 18/8 (304) stainless steel and explicitly says it is BPA- and phthalate-free.
The claim comes from the maker rather than a public independent finished-product phthalate test. The tray is not intended for children under three, cannot go in a microwave or oven, and should not be washed with bleach detergent.
