Plastic water bottles are one of the most common water bottles on the market because they are lightweight, practical and affordable for daily use. Most plastic water bottles are simple in design and easy to clean, making them suitable for daily drinking water for students, office workers, etc. Many plastic water bottles also come with leak-proof lids and detachable parts for easy cleaning and carrying. But it should be noted that water bottles made of food-grade BPA-free plastic should be used to ensure safety.
