PE vs PP: How to Choose the Right Plastic?

Polyethylene or polypropylene? PE and PP may look similar, but they behave very differently in real applications. In this video, we compare the engineering trade-offs between PE and PP, including flexibility, stiffness, toughness, heat resistance, cold-temperature performance, density, chemical resistance, processing behavior, and common applications. You’ll learn why PE is often preferred for flexible packaging, films, bottles, pipes, and impact-resistant products, while PP is widely used in rigid packaging, automotive parts, fibers, caps, living hinges, and heat-resistant applications.
