WHY POLYCARBONATE

Polycarbonate, which is also known as LEXAN from GE or MAKROLON from Bayer, is the strongest form of plastic currently available for water bottles.

It has glass-like clarity, appearance, and durability.  It will also withstand substantial heat and will not distort its shape or develop an odor or give a funny "plastic" taste to the water. 

For these advantages, PC is the material of choice for returnable bottles.

It is by far the most costly, but it offers the longest life of any plastic currently used for water storage and consumption. This type of plastic can be identified with a #7 inside the recycling triangle on the bottom of the bottle.
