The new container is made of Eastman Tritan copolyster. What exactly is a copolyester?
There is a lot of chemistry involved in the explanation, but basically, here’s how it works: Polyesters are made by stringing together a chain of esters using multifunctional molecules (acids or esters). The polyester most people are familiar with is called PET, and some copolyesters are based on PET but tailored to yield a range of properties for specific applications. Eastman’s new Tritan™ copolyester is produced in a similar way, but it is not based on PET chemistry, but rather a new monomer that gives it higher heat resistance, excellent impact resistance and increased resistance to cleaning agents.
