MateriumPlastic identifier
What does recycling number 5 mean? PP · polypropylene
Markdown ↗Resin identification code 5 identifies PP · polypropylene. It describes the plastic family of the marked component; it does not by itself tell you whether your local service accepts the item.
What to check yourself
- Find the number and letters on the actual component. Photograph the mark and the whole object together so you can connect the code to the correct part.
- Some tubs, closures and reusable containers use PP. A marked lid and an unmarked pot need separate checks. The code does not establish food-contact suitability or a safe heating temperature.
- Separate your observations about the body, cap, label and any lining. A mark on one part does not identify every material in the assembly.
- Check the collection service for your postcode and the exact item format. Use its current instructions for lids, cleaning and drop-off options.
Make the next step useful
A useful record includes the code, the item format and the local instruction you checked. Avoid replacing a specific collection rule with a general claim that this resin is recyclable everywhere.
