Leif rating: Likely Poor

PlanetBox is a stainless steel lunch box brand founded in 2009 to reduce single-use plastic waste, now owned by Lifetime Brands. The company emphasizes product durability and material safety—made from food-grade stainless steel and silicone, free of lead, phthalates, PVC, and BPA—with a claimed lifecycle benefit of eliminating 180 single-use containers per year per user. However, the brand lacks transparency on where and how materials are sourced, provides no published labor standards or supply chain audits, and has not obtained third-party environmental certifications or published a carbon footprint.
