Since 2005 we’ve reduced the plastic in our 0.5 L bottles by 40% (based on a weighted average). This includes having shorter caps than some other bottled beverages, making it difficult to open for some consumers. To open, we recommend avoiding squeezing the bottle too tightly. Because our bottles use less plastic, squeezing the bottle will force pressure build up making it more difficult to turn the cap, resulting in the water being forced up into the bottle neck once the cap is open, resulting in spills.
