From: Steve Wasik President, SIGG USA Re:
SIGG’s Bottle Liner
One of the reasons SIGG is the world leader in the manufacturing of premium water bottles is because of our proprietary bottle liner. This special liner is a water-based, non-toxic polymer which has been perfected over decades of Swiss craftsmanship. Like Coca-Cola’s soft drink recipe, the SIGG liner formula remains secret and unavailable to third parties in order to protect our competitive advantage. The Swiss have confirmed to me the following information which may be of interest to you: •
The SIGG “internal protection lacquer” (a.k.a. - the bottle liner) meets and exceeds requirements outlined by the USA FDA regulations (175.300). The liner is micro thin and still allows for the bottle to be 100% recyclable.
•
Based on multiple tests (both in-house and independent), the SIGG liner does not impart any taste or odors into the liquid. The liner is resistant to fruit juice acids, isotonic/energy drinks, alcohol and virtually any consumable beverage. Due to the finish/porosity of the liner, SIGGs outperform polycarbonate #7 (Lexan) and other plastic materials at reducing bacteria build-up and ease of cleaning.
•
SIGG’s bottle liner is totally inert because it is baked on at extremely high temperatures (over 200 degrees Celsius). The liner is flexible and remains intact and fully functioning no matter how dented the outside of the bottle becomes due to rough use.
•
SIGGs are safe to be placed in the dishwasher with no harm to the liner. The Swiss believe the bottles can be washed more thoroughly by hand in hot soapy water. Dark spots which materialize in the bottle are sugar deposits and can typically be cleaned by baking soda or SIGG cleaning tablets.
•
In addition, SIGG’s liner protects from any migration or leaching of the liner & container into the liquid. All tests of the liquid reveal no trace (0 %) of any of the following chemicals: Perfluorooctanoic Acid (PFOA), Bysphenol A (BPA) and Bysphenol B (BPB).

“Only the 2 bottles manufactured by SIGG, the market leader, showed no traces of aluminum... The manufacturer SIGG shows that it is possible to avoid residue from synthetic coating.” - OKO independent test, Germany 1997

“According to the results of our evaluation, use of a SIGG bottle does not add to the beverage any particles and/or components which are harmful to human health, or which alter the odor or flavor of the beverage.” - Dr. Ulrich Nehring, Institute Nehring, 2001

“While the polycarbonate bottles we tested leached a significant amount of BPA, the SIGG bottles – both new & used – showed no detectable BPA.” - Jonathan Chun, PhD, Alliance Tech, USA 2007
