A plastic bottle with a screw cap is a versatile container, typically made from PET or HDPE plastic, featuring a threaded neck and a matching removable cap that provides a secure, leak-proof seal for storing liquids or powders like water, juices, chemicals, or cosmetics, available in various sizes (ml/L) and designs for everyday use, travel, or specialized purposes. The screw cap allows for easy opening, closing, and refilling, ensuring contents stay fresh and preventing spills.
