SIGG

Sigg Switzerland AG is a Swiss manufacturing company with its headquarters in Frauenfeld. Sigg bottles are bottles designed and manufactured in Switzerland from aluminum or in China from stainless steel. The aluminum bottles are made by an extruding press which forms an aluminum puck into a cylinder in a single movement after which it is pressed into one of several possible bottle sizes. A separate threading ring is inserted and secured. Once the bottle has been formed, it is cleaned and the interior is sprayed with a food-compatible stove enamel which is heated while the outside is coated and heat bonded with powder paint.
