As more Americans switch to reusable drinkware, questions about material safety have become increasingly important. One common concern is whether stainless steel contains BPA—a chemical often associated with plastic products. The good news? Stainless steel is naturally BPA-free, making it a safe and reliable choice for everyday hydration.
What Is BPA and Why Does It Matter?
Bisphenol A (BPA) is an industrial chemical used in the production of certain plastics and resins. It’s commonly found in disposable water bottles, food containers, and the linings of canned goods. Studies have linked BPA exposure to potential health risks, including hormonal disruption and developmental issues.
Why Stainless Steel Is a Safer Alternative
- No BPA: Stainless steel is a metal alloy and contains no plastic-based compounds
- Non-reactive surface: Doesn’t leach chemicals into beverages
- Durable and reusable: Reduces reliance on disposable plastics
- Easy to clean: Resists staining and odor retention
Common Stainless Steel Grades for Drinkware
| Grade | Properties | Use Case |
|---|---|---|
| 304 | Corrosion-resistant, food-safe | Tumblers, bottles, cookware |
| 316 | Higher corrosion resistance | Medical-grade, marine use |
