lunchbox/BentoBox 1.2 litres, 3 inserts | Catering at very favourable prices 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 degradation, Bacterial growth in seals and crevices and Thermal warping and seal failure 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 Plastic (likely polypropylene or polyethylene) 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.
