plastic water bottle-A very light container that is used to hold liquids.It does not tolerate high temperatures and is usually used to hold room temperature drinks. Multi-use plastic water bottles can be made from high-density polyethylene (HDPE), low-density polyethylene (LDPE), copolyester, or polypropylene. They all offer the advantage of being durable, lightweight, dishwasher-safe, and BPA-free. The main difference between each type of water bottle is the flexibility of the material. Copolyester and polypropylene offer the greatest rigidity; HDPE retains some flexibility; LDPE (most commonly associated with collapsible, squeeze bottles) is highly flexible.As small as 150 milliliters can be used for babies, and as large as 1 gallon or even 2 gallons can be used at the gym to keep you energized all day. We can put a mark on the cup and a time line to remind you to drink, so you don't have to worry about forgetting to drink.
