sigg的涂层是为了防止铝析出污染饮品,同时也防止酸性饮品对铝的腐蚀。sigg用铝其实就是为了实现轻量化所做的一种妥协

Due to SIGG's special, proprietary internal coating, these high-tech bottles are resistant to fruit juice acids, energy drinks, alcohol and virtually any consumable beverage.

SIGG bottles have a non-toxic, protective liner that has been thoroughly tested both in Europe and in the USA to ensure against leaching – so no aluminum will seep into your beverage. |
