Buyers in the EU and North America now ask for recycled content by default. Here is what PCR actually is, how it differs from rPET, and how we document it so your claims survive scrutiny.
Bottles from our catalogue — PET bottles available with PCR content.
PCR vs rPET — not the same label
rPET is recycled PET specifically. PCR (post-consumer recycled) is a broader term covering resin reclaimed from consumer waste streams, which can include PET, HDPE and more. Brands often quote ‘X% PCR PET’ to be precise.
Why buyers ask for it
Recycled content supports EPR and PPWR compliance and answers the ‘is this sustainable?’ question at the shelf. We offer PCR PET grades and can declare the exact recycled percentage per batch.
Avoiding greenwashing
Keep claims measurable: state the percentage, the standard (e.g. GRS where applicable) and the mass-balance route. Vague ‘eco-friendly’ wording invites challenge.
| Term | Meaning | When to claim |
|---|---|---|
| Virgin PET | New resin | Never as ‘recycled’ |
| rPET | Recycled PET only | When 100% from PET stream |
| PCR PET | Post-consumer recycled (any) | State % and standard |

Compliance note: Recycled-content claims must be verifiable, not assumed. Shijin supplies recycled-content PCR grades, and our sustainability wording follows the FTC Green Guides so your claims stay defensible in every market.
PCR content levels and what they change
PCR content is usually stated as a percentage of recycled resin blended with virgin. 25–30% is a common starting point that holds clarity and strength with little visual change; 50–70% makes a stronger claim but can show a faint tint; 100% PCR is possible but more brittle and less transparent, so it suits opaque or lightly tinted bottles.
The tint is the visible trade-off: recycled flake carries colour from its previous life, so higher PCR loads drift toward grey or amber unless matched with a masterbatch. Lock the percentage and the tint together.
Documenting the claim so it survives
- State the exact percentage and the standard (GRS where applicable), not “made with recycled plastic.”
- Use the mass-balance route where full segregation is impractical, and say so.
- Follow the FTC Green Guides wording so US claims stay defensible.
- Keep the GRS certificate and batch-level percentage in your technical file.
A measurable, documented claim is the difference between a sustainability story that sells and one that gets challenged.
What cosmetic formulas demand from the bottle
For cosmetic fills the bottle is part of the compliance and performance chain, not just a container. The body has to hold the formula without stress cracking or leaching, survive the filling line, and stay readable after months on a shelf or in a warehouse.
Across our 30+ blow-molding lines we see the same non-negotiables: a neck that seats the closure squarely, wall thickness tuned to the fill weight, and colour and decoration that survive transport and UV. A bottle that passes the bench test but fails the warehouse is not a pass.
If the formula is viscous, acidic or solvent-based, tell us at the enquiry stage. The resin choice and the lining of the closure both shift, and selecting them early is far cheaper than re-tooling after a failed stability test.
Capacities we stock for cosmetic
| Model | Material | Capacity | Neck |
|---|---|---|---|
| SJT0141 | PET | 141 ml | 32 mm |
| 360ml HDPE Cosmetic Bottle | HDPE | 360 ml | 28 mm |
| 500ml PE Shampoo & Body Wash Bottl | PE | 500 ml | 28 mm |
| SJT0491 | PET | 100 ml | 24/410 |
These are stock shapes from our catalogue — the same tools a buyer samples first before committing to a custom mold. Capacities run from small trial sizes to bulk drums, so most cosmetic programmes can start from an existing mold and skip tooling lead time.
Sampling from a stock mold also de-risks the launch: you get a real, fill-tested bottle in days, validate it on your line, then scale or customise once the volume is proven.
Compliance and documentation
Every food-contact and pharma-adjacent bottle we make is produced under ISO 9001 controls, with FDA, SGS and EU 10/2011 food-contact documentation available on request. For export we supply the material certificate and, where required, UN-marked HDPE options for chemical transport.
If your market needs a specific claim (BPA-free, documented recycled content, tamper-evident), tell us at the sampling stage so we select the right resin and closure before the first run.
Sampling and first-run support
Because the tool is cut in-house, sampling lead time is typically 3–10 days from drawing to first article. We hold the first-article sample against the drawing, confirm wall and weight, and only then move to bulk.
For a new programme that means you can prove the bottle on your filling line before committing to a large order — and repeats stay consistent because the same mold and resin are used on every run.
Frequently Asked Questions
Can PCR change the bottle colour?
At typical 25-100% loads PCR PET can show a faint tint; we match it to your masterbatch so the finish stays on-brand.
Which standard proves recycled content?
GRS (Global Recycled Standard) where applicable; we also declare batch-level percentage for defensible claims.
Does PCR change the bottle colour?

What standard proves recycled content?
GRS (Global Recycled Standard) where applicable, plus a declared batch-level percentage — that combination makes the claim defensible.
