Materials and contact
A concise, evidence-scoped look at where plastic and silicone sit in this product’s food, drink, mouth, steam, and condensate paths.
- Plastic contact
- Plastic is present; its contact path is not fully verified
- Silicone contact
- Some silicone contacts food, drink, or the mouth
Materials and contact path: Food contacts 18/8 stainless steel inside the canister and the removable silicone liner under the lid. The lid shell is polypropylene #5; Klean Kanteen says the liner covers the food-facing lid base. The O-ring and split-ring materials are not listed, and complete isolation of the plastic shell from steam and returning condensate is not documented.
“Not fully verified” means a relevant component, treatment, or variant still needs exact-product evidence. It is not a positive plastic-free or silicone-free claim.
