When buying a water bottle, many people first check not the capacity or shape, but the material marked on the cup. Terms such as PP, PC, Tritan and PETG are commonly seen on plastic water bottles, sports jugs, children’s cups and portable tumblers. Though seemingly all suitable for holding water and can be made transparent or translucent, these materials have distinct properties. When selecting material for a water bottle, it is not enough merely to confirm if it is food-grade. You also need to consider heat resistance, clarity, drop resistance, odor performance, cleaning methods and actual operating temperature range.
