Polyethylene (PE) is a type of plastic among many polymers in the vast world of plastics. Plastic is a broad term that encompasses a wide range of synthetic or semi-synthetic materials that can be molded, whereas polyethylene is specifically known for its versatility and is the most common plastic. Polyethylene comes in various densities including high-density (HDPE), low-density (LDPE), and linear low-density (LLDPE), catering to different applications from bottles and bags to heavy-duty industrial uses. While "plastic" can refer to materials ranging from PVC (polyvinyl chloride) to polystyrene and beyond, polyethylene stands out for its balance of strength, flexibility, and recyclability. This distinction is crucial for understanding material specifications for manufacturing, recycling efforts, and environmental impact assessments.

The price of polypropylene plastic can fluctuate widely based on market conditions, crude oil prices, and supply-demand dynamics. As of my last knowledge update in 2023, polypropylene typically ranges between $0.50 to $1.50 per pound in the United States market.

For large-volume buyers, such as manufacturers, prices may be at the lower end of this spectrum due to bulk purchasing discounts. It's also worth noting that geopolitical events, environmental policies, and technological advancements can greatly impact these prices. Therefore, for the most accurate and current pricing, potential buyers should consult with suppliers directly or monitor market reports.
