A plastic bottle cap is a type of closure used to seal and secure the contents of a bottle. It is typically made of plastic and is designed to fit tightly onto the top of a bottle, creating an airtight seal to prevent the contents from spilling or leaking out.
Plastic bottle caps come in a variety of shapes and sizes to fit different types of bottles, such as water bottles, soda bottles, and juice bottles. They can be made from various types of plastic, including polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET).
While plastic bottle caps can be convenient and practical, they can also have negative impacts on the environment if not disposed of properly. It is important to recycle plastic bottle caps whenever possible to reduce waste and prevent them from ending up in landfills or polluting the environment.
