What Does BPA-Free Mean for Water Bottles?

BPA stands for Bisphenol A, a chemical component once common in plastics, including polycarbonate bottled water containers and the epoxy linings of cans. Research emerged finding BPA can leach into food and drinks.

Since BPA mimics estrogen hormones in the body, causing potential developmental, neurological, and other health disorders, bottles clearly labeled BPA-free, like Klean Kanteens, avoid chemical and related derivatives, using only non-toxic materials touching the contents instead.

How Does Klean Kanteen Ensure Their Bottles Are BPA-Free?

As leaders in safe, durable stainless steel bottles, all Klean Kanteens get rigorously tested both internally and by accredited third-party labs to guarantee complete BPA and toxin-free construction.

They only use medical-grade stainless steel, bamboo, food-grade plastics, and silicone components that are completely free of BPA, phthalates, lead, and other hazardous substances. Their manufacturing facilities also minimize waste for ecological stewardship.

What Materials Are Used in Klean Kanteen Bottles?

The primary safe material touching liquid contents in Klean Kanteen bottles is corrosion-proof, high-grade stainless steel, containing food-safe 18/8 chrome and nickel alloy. Some plant-based materials are also used.

Bamboo elements on caps provide sustainable, renewable fiber free of BPAs. BPA-free Tritan plastic composes accessory straws, sippy spouts, and sports caps as durable soft complements to steel.

In the Klean Kanteen FAQs section, Klean Kanteen clearly answers the question:

Q: Do stainless steel bottles contain BPA?

A: No. Surgical stainless steel is a pure chromium and nickel alloy that meets food standards, avoiding plastics and linings where BPA risks occur.

Q: Does freezing water in BPA-free plastic bottles pose any toxicity issues?

A: Freezing is safe in BPA-free bottles as the stable materials won’t leak chemicals. Avoid freezing any water bottles since ice expansion stresses seams.

Q: Why might some old stainless steel bottles still contain BPA linings?

A: Historically, before BPA health risks emerged, some steel bottles had plastic linings to prevent metallic tastes, which we now know contained toxic BPA. Any modern, certified BPA-free bottles like Klean Kanteens avoid that obsolete practice.
