Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid vs Total Solution 3-Pack Plastic Food Storage Containers Set: which is safer?

Where these two actually differ

• We flag Silicone gasket degradation, Bacterial growth in vacuum seal and Surface corrosion under acidic conditions on the Klean Kanteen and not on the Snapware.
• We flag Microplastics from degradation, Mold and bacterial growth in seals and Leaching of oligomers or catalytic residues on the Snapware and not on the Klean Kanteen.
• The Klean Kanteen is Stainless steel body, silicone gasket lid seal where the Snapware is Polypropylene plastic containers, 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.
