Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid vs Twist 'n Loc Food Storage Containers for School Lunch and Meal Prep: 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 Ziploc.
• We flag Microplastics from degradation under heat or mechanical stress, Leaching of trace monomers or oligomers from aged or stressed plastic and Seal degradation and loss of food freshness or contamination risk on the Ziploc and not on the Klean Kanteen.
• The Klean Kanteen is Stainless steel body, silicone gasket lid seal where the Ziploc is polypropylene (PP) plastic, snap-lock lid, 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.
