Many customers always ask me about the difference between Polyethylene（PE） and polypropylene （PP）products. Today we will talk about this topic.

PP (polypropylene) and PE (polyethylene) are both types of plastics, but they have different properties that can help you distinguish between them. One way to tell the difference is by looking at the physical characteristics of the product. Polypropylene is generally stiffer and more heat-resistant than polyethylene. Polyethylene, on the other hand, is more flexible and has a lower melting point. You can also look for recycling codes on the product. Polypropylene is typically marked with the number 5 inside the recycling symbol, while polyethylene is marked with the number 2. If you're still unsure, you can consult the product packaging or contact the manufacturer for more information about the materials used in the product.
