PlanetBox
One of the few brands whose whole catalogue holds the line, not just its hero product. The Rover is an all-stainless tray with a stainless lid and stainless latches and rates plastic-free outright; across the rest of the range the spec line is almost always some version of "stainless steel and LFGB silicone", with silicone confined to gaskets, spouts and lids and no plastic in the food path. Where the line has grown into harder categories it has kept the discipline - the leakproof boxes seal with a bare steel lid and a drop-in silicone ring rather than the usual plastic lid frame, the vacuum food jar has a steel screw lid instead of a moulded plastic one, and the PlanetGoods glass storage lids are a glass window in a silicone rim rather than a plastic disc with clamps. The exception is the 12oz Pour Spout kids' bottle, which uses a polypropylene cap: read "PlanetBox is plastic-free" as true of the lunch and food lines rather than as a guarantee covering every SKU.
How clear are their specs?
Materials are stated plainly in a spec line on every product page, usually naming the steel grade, the recycled content percentage, and the silicone certification. The gap is granularity - the spec covers the product as a whole rather than per component, so on multi-part items (which piece is the 18/0 lid, what the latch is) you end up inferring from photos and replacement-part listings.
Lead testing disclosure
Still publishes no test data - no named lab, no ppm or detection-limit figures, no safety page - which is why this stays false. But the claims are no longer purely generic. On every vacuum-insulated product the spec line now ends "Lead-free solder", and the bottle FAQ names the alloy as SAC (tin, silver and copper). That is a specific, checkable composition claim about exactly the part that matters: independent XRF testing (Lead Safe Mama) found PlanetBox lunchboxes lead-free but found a leaded solder dot on a PlanetBox water bottle, which the company reportedly removed after being contacted. The disclosure reads as a direct response to that finding. What is missing is the acknowledgement and the evidence - PlanetBox neither references the original result nor publishes or links any testing of its own, so a buyer is taking the alloy claim on trust.
