Newest Video: What is PP?

If you’ve been following our videos, you’ve learned that not all plastics are the same, in fact, there are hundreds of different kinds of plastic.

Thanks to the Society of Plastics Industry (SPI), they have kindly categorized all plastics into seven different categories: PET, HDPE, PVC, LDPE, PP, PS and the catch-all Other. Each plastic type has what we call a resin identification code on it. (Resin is just another word for “type-of-plastic.”) PP is short for Polypropylene. It is marked with the resin identification code “5”.
