FAQs - SIGG
Where Are SIGG Bottles Made?
All Aluminum SIGG bottles are made in Frauenfeld, Switzerland. Frauenfeld is one of the eight districts of the canton of Thurgau, Switzerland. Its capital, and the capital of Thurgau, is the city of Frauenfeld.
SIGG bottles are extruded from a single 'puck' of Aluminum, and can be recycled. Watch a video of our manufacturing process:
What About Your Stainless Steel Bottles?
Several of our loyal customers have told us that when they see the SIGG brand, they expect to get a Swiss-made product. Our high performance stainless steel bottles are designed by our team of Swiss engineers at SIGG Switzerland and forged in China from industrial strength, sanitary grade 18/8 stainless steel. A full-time Swiss Quality control Inspector lives and works full time at this facility, and the Swiss Product Management Team travels regularly from Switzerland to Asia to ensure that our manufacturing facility practices fair labor and manufactures in an environmentally responsible manner.
Is It Safe To Drink Out of Aluminum?
SIGG bottles have a water-based, non-toxic liner that has been thoroughly tested both in Europe and in the USA to ensure 0.0% leaching – so absolutely no migration of either the liner or the Aluminum of the bottle will seep into your beverage. SIGG has been manufacturing and perfecting metal beverage bottles for over 100 years. SIGGs have been around long before the BPA scare. Having been in this business for over 100 years, you can trust SIGG Switzerland to produce products of the highest quality and safety standards in the world.
Will SIGGs Leach Metal Into My Water?
No. There is no leaching of anything whatsoever, no metal, no liner, no nothing. Some may think Stainless Steel beverage containers may be better, but just because it's "Stainless Steel" doesn't mean a high quality grade of stainless steel is used in manufacturing the item. (kind of like Gold, is it 10K or 24K?). Scientific research shows that some stainless steel containers on the market WILL LEACH METAL into the water that's been poured into them!
What If I Scraped Or Chipped Off My Liner?
Some of our customers have inadvertently scraped or chipped off their liner exposing some of the Aluminum and have asked if the bottle was still safe to drink beverages from.
Research shows It's nearly impossible for the body to absorb enough aluminum to cause Alzheimer's. A study in May 2007 Journal of Alzheimer's Disease found that you would have to absorb MORE than 1,000 milligrams of aluminum each day to increase your risk of dementia.
That's the equivalent of drinking 1,000 cups of tea (one of the HIGHEST sources of aluminum in the human diet). Since the average person is exposed to less than 10 milligrams a day, you are pretty much safe.
But Doesn't Aluminum Cause Alzheimers?
No, it’s a myth that has persisted since 1965, when researchers found that exposing rabbits’ brains to aluminum caused nerve cell damage similar to Alzheimer’s. Many over-the-counter medicines contain Aluminum. One antacid tablet can contain 50 milligrams of Aluminum and a buffered aspirin tablet may contain about 10 to 20 milligrams of Aluminum. A SIGG bottle, even though is made of Aluminum, will not leach any Aluminum whatsoever into your drink because of our liner.
What Drinks Can I Put In My SIGG?
Any beverage considered safe to consume by a human. All SIGG bottle tops provide a 100% seal and do not leak.
Tip for Carbonated Beverages: fill the bottle no further than 2–3 cm below the lip. And before taking a drink, relieve the pressure inside the bottle by gently rotating the entire top.
Tip for Milk or Fruit Juices: drink within 12 hours of filling the bottle. Warmth and oxygen may initiate a fermentation process, which by the way is natural and can take place in any bottle, regardless of material.
Hot Tea or Coffee?: We do not recommend pouring hot tea or coffee into your Aluminum SIGG bottle. Aluminum conducts the heat and will render the SIGG untouchable when filled with boiling liquid. Extreme heat will also weaken the bottle and shorten its life. Use a Thermo bottle or a SIGG meant for Hot Beverages instead.
Ice Cubes?: Yes, you can put ice, crushed ice and ice cubes in your SIGG - BUT DO NOT PUT THE SIGG IN THE FREEZER AND DO NOT ALLOW any beverage inside the SIGG bottle to FREEZE. The beverage will expand and crack open the SIGG bottle (much like a can of soda in a freezer). Do not leave it in your car out in the cold if it will freeze. Do not put it in your refrigerator if your refrigerator has been known to freeze items. We cannot replace bottles that have been damaged due to freezing no matter the circumstances. This is the only way a SIGG will crack open.
Can I Store Gas In My SIGG?
No, it is a beverage container. SIGG used to make fuel containers for this purpose, but they had a heavier wall. We do not recommend storing any fuel in SIGG beverage bottles whatsoever. We do not carry fuel bottles at this time.
Best Way To Clean My SIGG?
We recommend rinsing your SIGG thoroughly under the faucet with warm, soapy water at the end of every day and letting it air dry with the top off. When more thorough cleaning is required, you can use baking soda and vinegar. For tough jobs, pick up some SIGG cleaning tablets and a SIGG brush. Do not use a hard bristled brush to clean the interior of your SIGG bottle as this will damage the liner.
We do not recommend using the dishwasher to wash your SIGG bottles. The Dishwasher is too harsh and will damage the non-toxic food-based paint on your bottle, so if the design is important to you and you don't want the paint to fade or maybe chip off - avoid the dishwasher. Also, the opening of the SIGG bottle is small - and a dishwasher cannot shoot the water all the way up into the bottle to clean it thoroughly. Some tops have rubber gaskets on them - which will deteriorate in a dishwasher and cause your bottle to leak. DO NOT USE METAL TO PICK OR SCRAPE AT THREADS, DO NOT USE STEEL WOOL, DO NOT USE HARSH ABRASIVES
SIGG Bottle Or Liner Issues?
My Liner Is Chipping Off! Our liner is sprayed in, baked on at extreme temperatures, and does not chip off. What happens sometimes, especially when you drink fruit juices or sugary drinks, is that the sugar will form a crystalline layer inside your SIGG bottle, it is this sugary coating that will eventually chip off and have you think it is the liner.
There Are Dark Spots In My SIGG!
These discolorations are also caused by sugar deposits. Tip: thoroughly rinse out the bottle with hot water. To deal with heavier soiling, try a SIGG cleaning brush or SIGG Bottle Clean cleaning tablets.
There Are Spots In My SIGG and I Only Use It For Water!
These are called mineral deposits. To remove them, fill your clean dry SIGG bottle with Distilled White Vinegar and let soak for 24 hours, then rinse with warm water and 1 TBSP of Baking Soda, then let air dry. Repeat for stubborn mineral deposits.
My SIGG Bottle Has a Metallic Taste or Rust...
First, make sure you are using premium filtered water. SIGGs do not leach metals into your beverage, so if there is a metallic taste, this is probably due to mineral deposits that are starting to form inside your bottle. Here's what you can do: Soak your SIGG Bottle overnight with warm Water and 1 TBSP of Baking Soda, this should neutralize the mineral deposits forming in your bottle. Please make sure you are using a good filtered water.
My SIGG Bottle Has a Funny Smell / Moldy Smell...
First, make sure you are not using a smelly old dishtowel to wipe down or dry your SIGG. Fill your SIGG with 1/4 Cup Distilled White Vinegar, 1 tsp Baking Soda and a small drop of dishwashing liquid. Put top on bottle and allow to sit for 24 hours, then rinse with warm water. Allow SIGG to air dry.
My SIGG Bottle Has a Dent On the Bottom This dent is supposed to be there.
It is part of the Manufacturing process.
My SIGG Bottle Has Cracked Open We do our best to inform people not to allow the liquid inside your SIGG bottle to freeze, no matter how full the bottle is.
SIGG bottles are tough, but like a soda can, will crack open if the contents are allowed to freeze. Do not place your SIGG anywhere if you think there is a possibility the liquid may freeze inside the bottle (don't even leave it in your car overnight!)- empty the bottle completely. We cannot replace bottles that have been damaged due to freezing. If you did freeze your bottle, and it wasn't destroyed, consider yourself lucky - it is still safe to use.
What Are SIGG Tops Made Of?
The primary ingredient utilized in the manufacturing of SIGG bottle tops is Polypropylene (PP). It is recyclable.
The softer, white material on the SIGG screw tops is Santoprene, a thermoplastic rubber which helps to ensure a secure, leak-proof seal.
The material used to make SIGG bottle tops fulfills the requirements of materials intended to come into contact with food as described in: FDA, CFR, Title 21(2004) 177.1520 a) (3)(i)(c)(1), 8b) and c) 3.1a Olefin polymers.
What Is The SIGG Liner Made Of? Is It BPA Free?
SIGG has proprietary rights with a 3rd party producer of our liner formula. In other words, we do not produce it ourselves. This supplier is based in Switzerland and has an impeccable reputation for quality and safety. SIGG is THE ONLY WATER BOTTLE ON THE MARKET to use this special liner. As there are many copy-cat manufacturers in the market that would like to get their hands on this formula, our supplier has an agreement with SIGG to keep his formula strictly confidential.
Because we know that this liner is the very best on the market and we would like to continue working with this supplier, we have honored this agreement.
More important than the formula of the liner – is THE PERFORMANCE of the liner. Very thorough migration testing in laboratories around the world is conducted regularly and has consistently shown SIGG bottles to have NO PRESENCE WHATSOEVER of phthalates, Perfluorooctanoic Acid (PFOA), Bysphenol A (BPA), Bysphenol B (BPB) or any other chemicals which scientists have deemed as potentially harmful.
I Dropped My Bottle, And...
The Top Broke Off...!
Our bottle top has been tested and meets a very high standard of mechanical durability. Yet the stress of a full bottle landing at an unfortunate angle may be sufficient to break the plastic, no matter how long you've owned your Bottle. Regrettably, there is not much to be done about this. But you can buy a spare part replacement for any SIGG bottle top.
My Bottle Dented...!
Again, our bottle has been tested and meets a very high standard of mechanical durability while being lightweight. Yet the stress of a full bottle landing at an unfortunate angle may be sufficient to dent it, no matter how long you've owned your Bottle. Regrettably, there is not much to be done about this. Please Note:A dented SIGG Bottle will not affect the functionality of the liner. SIGG will not replace damaged bottles due to misuse and mishandling, and that includes dropping them. We recommend parental supervision especially if your child is under the age of 3.
My Seal Leaks. Why?
All SIGG seals are guaranteed watertight. But even so, they can become worn through intensive use. Tip: do not put seals in the dishwasher. To clean them, remove and rinse with hot water, then simply leave to dry naturally. By the way, it often helps to replace the bottle seal, which is available as a spare part from your dealer.
The Paint Is Flaking Off The Outside Of My Bottle. Why?
Regular quality control ensures a very tough outer coating. However, scratches and dents may cause it to crack. If moisture then penetrates between the coating and the bottle wall, the paint may start to flake. This does not in any way affect the bottle’s functionality.
Can SIGG Bottles Be Used For Boiling Water?
No. Strong heat can damage the outer coating.
