rPET is specifically recycled PET. PCR is the broader term for any post-consumer recycled plastic, which can include PET, HDPE and others.
Definitions: rPET, PCR and PIR side by side
rPET is recycled polyethylene terephthalate — the same polymer as standard PET, but made from recovered bottle flake. PCR (post-consumer recycled) is the wider category that covers any plastic recovered after consumer use, including rPET, rHDPE and rPP. PIR (post-industrial recycled) is factory scrap that never reached the consumer — cheaper, but it doesn’t carry the same sustainability story.
| Term | Source | Typical use |
|---|---|---|
| rPET | Recycled PET bottles | Clear cosmetic & beverage bottles |
| PCR | Any post-consumer plastic | Bottles, jars, caps (HDPE, PET, PP) |
| PIR | Factory offcuts | Lower-cost recycled content |
Why the distinction matters for claims
If you market a bottle as “recycled,” regulators and retailers increasingly want proof of the exact recycled content and its source. The FTC Green Guides (US) and EU rules require claims to be substantiated, which is why a Global Recycled Standard (GRS) certificate — tracing recycled input through the supply chain — has become the de facto proof for export packaging.
For cosmetics specifically, PCR content must still meet EU 10/2011 food-contact migration limits when it touches the product, so work with a supplier that can document both recycled content and compliance.

Frequently Asked Questions
What is the difference between rPET and PCR?
rPET is specifically recycled PET. PCR is the broader term for any post-consumer recycled plastic, which can include PET, HDPE and others.
Can a bottle be 100% PCR?
Yes, but full-PCR bottles are more brittle and less transparent than virgin PET, so many brands blend 30–70% PCR with virgin resin to keep clarity and drop-impact strength.
Does PCR cost more than virgin plastic?
Usually. PCR flake supply is still tightening, so PCR grades often carry a premium over virgin resin — factor that into your landed cost early.
