How is a SIGG aluminum water bottle made, and what's inside?

SIGG has been designing and manufacturing water bottles since 1908 in our own factory in Switzerland – one of the greenest countries on the planet. In our continuing effort to raise the standard for environmental performance, we recently upgraded all our quality procedures and processes. As a result, SIGG can say with even more confidence all ingredients used in our products are in conformance with both European and U.S. regulatory requirements. They are also certified and free of harmful chemicals. Furthermore, all ingredients inside our bottles are free of any volatile organic compounds (VOCs), phthalates, BADGE, BFDGE, and NOGE. In particular, our ingredients are free1 of BPA. SIGG bottles are independently lab tested to affirm our products meet our promi

What is inside the SIGG high-performance EcoCare Liner?

The new EcoCare liner by SIGG is a high-quality internal coating that insures a fresh, clean taste with no metallic aftertaste. This chemically inert liner is made of a unique formulation of non-toxic ingredients. The new liner is an ultra-thin coating that is applied uniformly to the inside of all SIGG aluminum bottles. Once applied, the liner is then cured at temperatures between 190° Celsius and 200° Celsius.

Ingredients:

The new EcoCare liner by SIGG is comprised of many ingredients. The primary compounds utilized are a special combination of ultra-thin layer forming co-polyesters, many of which are commonly found in different variations across a variety of well-known food and beverage brand products.

The materials used in producing the liner are BPA-Free and Phthalate-Free, as well as being free of any VOCs (volatile organic compounds).

Additional ingredients used during the manufacturing process guarantee that the new EcoCare Liner by SIGG is durable, highly effective, and applied more efficiently. This improved efficiency helps to improve capacity and thus allows SIGG to better satisfy the growing global demand for SIGG products.

The new EcoCare liner by SIGG also contains various flow enhancing additives. These waxy solids found in naturally occurring fatty acids, guarantee that the liner can be applied uniformly, thus greatly increasing the products durability.

All ingredients used in the formulation and manufacturing of the new EcoCare liner by SIGG comply with the required EU and FDA guidelines, including EG 1935/2004 and FDA 21 CFR 175.300.

What is a Carbon Footprint?

Everybody knows that the emission of carbon dioxide and other greenhouse gases is responsible for global warming. A few years ago, the phrase “carbon footprint” was coined to measure the amount of greenhouse gases of individual products (the “product carbon footprint”) or companies (the “corporate carbon footprint”).

Where are SIGG aluminum bottles manufactured?

All SIGG aluminum bottles are manufactured in our company-owned factory in Frauenfeld, Switzerland. 

Can dents in the bottle damage the inner coating?

No, the inner coating is highly elastic. Dents cannot crack the coating and the SIGG bottle remains perfectly usable.

There is a notch or indentation at the bottom of my new bottle? Is this normal?

Yes, this is what we call an indent for indexing. Every SIGG bottle has one. It is there to help position the bottle for printing. You can watch a video about our manufacturing process at sigg.com/en/about-sigg/knowledge-base/. This indentation does not impact the stability of your bottle in any way.

Can I use my SIGG bottle for fizzy drinks, too?

Yes, of course. All SIGG bottle tops provide a 100% seal and cannot leak. Hint: fill the bottle no further than 2–3 cm or 1 inch below the lip. And before taking a drink, relieve the pressure inside the bottle by gently rotating the entire top.

I noticed that my bottle’s inner coating has darkened, and there are dark spots on the base. What can I do about this?

These discolorations are caused by sugar deposits. Hint: thoroughly rinse the bottle with hot water. To deal with heavier soiling, try a SIGG cleaning brush or SIGG Bottle Clean cleaning tablets.

How can I clean my SIGG bottle properly?

Always clean your SIGG bottle manually. Rinse your bottle and bottle cap with hot water after each use, let it dry and always store bottle and cap separately. If your bottle gets very dirty or stained, our special cleaning tablets SIGG BOTTLE CLEAN and our SIGG cleaning brush can come in handy. In addition, you should also clean the individual parts of your kids’ and active tops regularly by hand. Taking the caps apart for cleaning is pretty easy (see illustration).

Can I put my SIGG bottle in the dishwasher?

Cleaning in the dishwasher is dissuaded as dishwashing detergents may affect the exterior and interior coatings of your bottle over time. What’s more, dishwashers don’t do a very good job of cleaning the classic SIGG bottles with their fairly small mouths. So you can enjoy your SIGG bottle for a long time to come, we recommend you clean it regularly by hand. Rinse your bottle and bottle cap with hot water after each use, let it dry and always store bottle and cap separately.

What else do I have to look out for? What do the symbols on the label attached at the bottom of the bottle mean?

I dropped my bottle and the bottle top broke off. How can that happen?

The 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. Regrettably, there is not much to be done about this. But you can buy a replacement for any SIGG bottle top.

My seal leaks. Why?

All SIGG caps are guaranteed leak-proof. But even so, they can become worn through intensive use.
Hint: do not put bottle caps 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, severe scratches and dents may cause it to crack. If moisture gets 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.

Can I fill SIGG bottles with apple juice?

Yes. The inner coating has been tested with various drinks, apple juice in particular. The SIGG bottle passes this test with flying colours.
Tip: drink apple juice 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.
