There are many [types of plastic](https://greenhousecover.com/store/), each designed for specific purposes and properties. Common varieties include polyethylene (used in bags and bottles), polypropylene (found in food containers), polyvinyl chloride or PVC (used in pipes and flooring), and polystyrene (used in packaging and insulation). Polyethylene terephthalate or PET is widely used in beverage bottles, while acrylic and nylon serve industrial and household needs. Each type differs in strength, flexibility, heat resistance, and recyclability. Understanding these plastics helps in choosing the right material for manufacturing, packaging, or daily use while promoting better recycling and environmental sustainability.
