Is the plastic used in Zrii bottles safe? Which plastics have been shown to leach?
Within the world of food-grade plastics, High Density Polyethylene HDPE #2 (Zrii’s bottle) is considered one of the safest and easiest to recycle. There has been some concern in recent months regarding the leaching of chemicals in plastics. This concern stemmed from a study suggesting that #7 plastics (also called Lexan) can produce the unwanted chemical bisphenol-A (BPA), thus leading to a variety of health issues. One major manufacturer of reusable sports bottles just switched form #7 plastics back to HDPE #2 for this reason.
