Plastic materials are synthetic substances made from polymers, which are long chains of molecules. They are versatile and can be molded into various shapes and forms, making them useful in countless applications, from packaging to construction. Common types of plastics include polyethylene, polypropylene, and polyvinyl chloride (PVC). These materials are lightweight, durable, and resistant to moisture, which contributes to their popularity. However, the environmental impact of plastic waste has raised concerns, leading to increased interest in recycling and the development of biodegradable alternatives. Efforts are ongoing to reduce plastic pollution and promote sustainable practices.
