In our post on Bisphenol A from Nalgene water bottles and other polycarbonate bottles, a number of commenters asked about the lining in SIGG aluminum bottles, expressing concern that their linings might leach BPA. So we asked them, and received a response from the CEO, Steve Wasik. He says that SIGG uses a proprietary liner formula from a Swiss supplier with “an impeccable reputation for quality” but that“as there are many copy-cat manufacturers in the market (most based in China) that would like to get their hands on this formula, our supplier has an agreement with SIGG to keep his formula confidential.”
Wasik continues: “Very thorough migration testing in laboratories around the world is conducted regularly and has consistently shown SIGG aluminum bottles to have nopresence of lead, phthalates, Perfluorooctanoic Acid (PFOA), Bysphenol A (BPA), Bysphenol B (BPB) or any other chemicals which scientists have deemed as potentially harmful.
“Despite the scientific evidence that SIGG bottles are 100% safe, I understand the desire of some people to know more about the proprietary SIGG liner. As our Swiss supplier insists on protecting his formula & keeping it confidential, I have commenced the process of exploring new suppliers.”
Conclusion: We are not sure if the lining of SIGG bottles is made with BPA or not, To read more about what treehugger found, click HERE
And of course all Hydro Flask’s are made from 100% 18/8 Stainless Steel that contains 0 chemicals. No liner to get scratched, and as always, NO BPA!
