Polypropylene (PP) plastic cups are often deemed suitable for hot beverages, including hot coffee. This is primarily because they have a high melting point compared to other plastics, reducing the likelihood of chemical release when exposed to heat. PP cups can generally withstand temperatures that hot coffee typically reaches without deforming or releasing harmful chemicals. They offer superior heat management for hot beverages due to their thermal insulation properties. The fibre-plastic composite structure creates an effective barrier that reduces heat transfer to the exterior surface, allowing for comfortable handling. Additionally, polypropylene's non-absorbent nature maintains drink temperature while keeping the exterior surface cool to the touch.

The melting point of polypropylene varies from 170 to 180 degrees Celsius, and it is considered one of the best eco-friendly plastics. Cups made from this material are highly durable and functional, making them suitable for coffee shops and restaurants. They are also affordable, strong, and do not contaminate drinks or food, even when reaching a specific temperature. Polypropylene is used extensively in automobile applications due to its high melting point and chemical resistance. It is also favoured for its rigidity and dimensional stability in furniture and home appliances.

While PP cups are suitable for hot coffee, it is important to ensure that any cup used for hot beverages is specifically designed for that purpose to avoid safety risks.
