What is the difference between Polypropylene and PES?
We originally launched thinkbaby with our PES version. Let us start by saying that both materials are equally safe and free of Bisphenol-A (BPA), lead, PVC, phthalates, nitrosamines and biologically toxic chemicals. Both materials are dishwasher safe (Top Rack Recommended). Both are medical grade plastics Both bottles come packaged with our patented anti-colic and no spill nipples. Both are recommended by Healthy Child Health World.
So what's the difference?
We typically explain it like buying Honda Civic vs Honda Accord. Both are quality products that get you where you want to go - same thing with PP vs PES bottles. But there are some subtle differences.
Polypropylene (PP) is a softer plastic and has a slightly milky color. PP has the advantage of being easily recycled at most recycling locations.
PES is a higher end plastic. It is clear with a slight honey color. PES can withstand super high heat. It is rigid plastic. PES can be recycled by sending bottles to a recycling plant that works with PES or back to the manufacturer.
Why did we launch the PP bottle if its nearly the same? We had the ability to create both a higher end line and a product that could fit all economic groups. What's the point in being focused on providing safe products, if the price points are out of reach from the people that need it.
