Lunchbox Clip & Go XL, Speisebehälter mit 3 Einsätzen, Kunststoff Grün 2.2L vs Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid: which is safer?

Where these two actually differ

• We flag Microplastics from heating or degradation, Silicone gasket degradation and leaching and Mold or bacterial growth in seals on the Emsa and not on the Klean Kanteen.
• We flag Silicone gasket degradation, Bacterial growth in vacuum seal and Surface corrosion under acidic conditions on the Klean Kanteen and not on the Emsa.
• The Emsa is polypropylene plastic with silicone gaskets where the Klean Kanteen is Stainless steel body, silicone gasket lid seal, which is most of the difference in these two grades.
• The gap is 30 points, wide enough that this is not a close call, and the Klean Kanteen is the one to buy.
