Every beauty brand now wants the sustainability story on the pouch — and every EU market now treats that story as a legal statement, not a slogan. The gap between "made from recycled bottles" as marketing and as a provable fact is a documentation problem, and it has a precise solution. This is what rPET actually is, what certification does and does not guarantee, and the wording that will still be standing when a regulator or a retailer's compliance team reads the hangtag.
1. What rPET actually is
rPET fabric is polyester made from recycled material — in practice, overwhelmingly from post-consumer PET bottles. Bottles are collected, sorted, washed, flaked, melted and extruded into yarn; the yarn is woven or knitted into fabric in the same weights as virgin polyester (common pouch weights run 190T–600D and beyond). Mechanically and visually it behaves like virgin polyester: same printability, same coatings, same stitch behaviour.
Three practical differences matter to a buyer:
- Price — certified rPET fabric costs more than virgin equivalent, typically a low double-digit percentage, plus the certification overhead below.
- Shade control — recycled feedstock has slightly wider shade variation; for very strict colour matching, specify tighter lab-dip tolerances (see the sampling workflow).
- The claim is only as strong as the paper — the fabric in your pouch is indistinguishable from virgin polyester by looking at it. Everything rides on the chain of custody.
2. GRS and RCS: what the certificates actually certify
The two standards you will meet from Textile Exchange:
| RCS (Recycled Claim Standard) | GRS (Global Recycled Standard) | |
|---|---|---|
| Minimum recycled content | 5% | 20% |
| Verifies chain of custody | Yes | Yes |
| Adds social requirements | No | Yes |
| Adds environmental processing rules | No | Yes (chemicals, wastewater) |
| Typical use | Entry-level recycled claims | Brand programs with published commitments |
Certification works as a chain of custody: the recycler, the yarn spinner, the fabric mill, the printer or dyer, and the cut-and-sew factory are each certified, and each passes a transaction certificate (TC) — a document issued per shipment — down the chain. Your proof for a batch of pouches is the stack of TCs ending at the factory that sewed them, tied to your purchase order.
3. Where the chain breaks
The fabric arriving with a certificate does not finish the job. The weak points:
- The decoration stage. If printing or dyeing happens at a non-certified processor, the chain has a gap. For GRS claims, every processing step on the certified material should be certified.
- Mixed batches. If the factory runs certified rPET and virgin fabric on the same lines without documented segregation, the claim for "your" batch is no longer provable.
- The TC gap. A supplier with a valid scope certificate still needs a transaction certificate for your shipment. Scope certificate = allowed to; TC = actually did, this lot. Asking for one and being shown the other is the most common failure.
- Claims beyond the fabric. The zip, lining, coating and trims are usually not recycled. A pouch that is 100% rPET shell fabric is not a "100% recycled pouch" — the honest claim names the component.
4. Wording that survives the EU Green Claims rules
The EU Green Claims Directive — on top of existing national rules like Germany's UWG and France's AGEC law — pushes environmental claims toward specificity and evidence. The pattern that survives:
| Wording | Verdict | Why |
|---|---|---|
| "Made from recycled polyester (GRS-certified)" | Strong | Names material, names standard, is verifiable |
| "Shell fabric: 100% post-consumer recycled polyester" | Strong | Names the component and the feedstock type |
| "Recycled bag" | Weak | Unqualified — which part? how much? proven how? |
| "Eco-friendly" / "sustainable" / "green" | Strikes out | Unverifiable as written; the exact category regulators are removing |
| "Made from recycled bottles" alone | Risky | Implies the whole product; true only for the shell fabric |
The same discipline applies to numbers. "This pouch equals N bottles" claims need a documented grams-per-bottle assumption and the actual fabric weight of the pouch — write the arithmetic down before printing it.
5. How to verify a supplier before you believe the story
- Ask for the scope certificate and check it on the certifier's public database (Textile Exchange maintains one). Check the company name, the scope (does it cover your product type?) and the expiry date.
- Ask for a TC from a recent shipment, redacted if needed. A certified supplier issues these constantly; hesitation is information.
- Confirm the decoration path is inside the certified chain if you intend a GRS claim.
- Write the TC requirement into the PO: "a GRS transaction certificate tied to this PO must be issued with the shipment documents".
- Agree the hangtag wording at the same time as the material, not at the packaging stage — legal teams approve faster when the claim matches the certificates already in hand.
The short version
rPET performs like virgin polyester and costs somewhat more; its entire value rides on documentation. GRS is the standard that covers both custody and processing; the scope certificate proves capability, the transaction certificate proves your batch. The chain breaks at decoration, at mixing, and at the moment someone accepts a scope certificate as proof of a shipment. Write the TC into the PO, name the component in the claim, and the sustainability story stops being a liability and becomes what it was supposed to be.
GAOHE is not a GRS-certified factory, and we will tell you that before you ask. Our cut-and-sew step sits outside the certified chain of custody, which means we cannot issue a transaction certificate for a finished bag, and a bag we sew cannot carry a GRS product claim — no matter how good the fabric's paperwork is. What we can do is source rPET fabric from certified mills — as we have for past programs — and pass the mill's own certificates to your team as the basis for a material-level claim on the shell fabric. In practice, most recycled-content programs we have run in recent years sat at exactly that level. If your compliance team requires a fully certified finished product, we will say so plainly at the quoting stage and tell you exactly what to demand from a certified factory — starting with the questions in section 5.
