Enerex products are housed in recyclable BPA-free PETE plastic containers to provide the best protection against oxidation, moisture, sunlight, and chemical migration from container to product. In all of these areas, PETE is virtually equal to that of glass but without the larger environmental footprint left by glass packaging. PETE plastic is far superior to that of HDPE plastic in all regards; HDPE plastic is used for the majority of products on the market. Unlike more costly PETE bottles, HDPE plastic facilitates the immediate degradation of the product inside as it is not a barrier to oxygen or moisture; studies also show high concentrations of chemical migration from HDPE bottles to product relative to that of PETE and glass bottles.
