In short, Arthur Andrew does not utilize any packaging materials that contain BPA.
Bis-phenol A, commonly referred to as BPA, is a compound that is utilized to make a plastic material that is used in certain baby bottles, reusable sport bottles, and even the linings of metal cans. The plastic material is known as polycarbonate, and was much more widely used in the past before BPA research was widely publicized. BPA is not used in the production of PET plastic, the type of material Arthur Andrew has chosen for its packaging. BPA is also not utilized as a chemical building block for any of the materials used in the manufacture of PET.
PET is a strong and lightweight plastic that is resistant to breaking and has been repeatedly shown as safe for use with consumable products for several decades. Unlike some plastics, PET does not leach chemicals such as dioxin. Dioxin is a chlorine-containing chemical that has no role or presence in the chemistry of PET plastic. The FDA has reviewed the safety of PET bottles and concluded that they do not leach substances into their contents under foreseeable conditions, conditions the bottle and its contents could likely incur through normal use.
PET bottles can be easily identifiable as they have a recycle code of 1. PET is the only plastic material with this code. PET also boasts the highest rate of recovery for recycled plastics, making it a more environmentally friendly choice among the bottle options. HDPE is another type of product that is commonly used with dietary supplements. It too is free of BPA, and is denoted by a recycle rating of 2.
It is also important to note that plastic PET and HDPE dietary supplement bottles are not going to go through certain "stressors" like plastic water bottles and baby bottles due to how they are likely to be stored. Most plastics are only shown to leach chemicals when repeatedly exposed to stressors such as heat (such as in a dishwasher) or exposure to long periods of UV light. So in realistic conditions, the plastic bottles of most supplements will not be put through the stressors necessary to cause plastics to begin to leach chemicals in the first place.
