Polypropylene
Polypropylene is one of the most common types of plastic materials used in manufacturing. It's like a versatile building block that can be turned into many different products. Companies value it because it's cost-effective, durable, and can be used in everything from food packaging to car parts. When someone mentions working with polypropylene (sometimes shortened to PP) in their resume, they're typically talking about manufacturing processes, quality control, or product development involving this material. It's similar to other plastics like polyethylene, but has its own unique properties that make it better for certain uses.
