Recycled PP (rPP) Bags — When Your Pack Needs Stiffness, Not Just Softness
Recycled polypropylene is the engineering answer when recycled PE is too soft for the job. Garment bags that must hang straight on a rail, document sleeves that must not crease, retail bags that must feel rigid in the hand — rPP delivers a stiffer, more heat-tolerant film while still carrying certified recycled content. We process rPP within the same GRS-certified, vertically integrated system as our core rPE line.
Technical profile
Technical Profile — Typical Values
| Material family | Recycled PP homopolymer / copolymer blends |
|---|---|
| PCR content | 30–100% where feedstock allows (GRS Scope Certificate TE-00057717) |
| Film thickness | 40–90 µm |
| Density | ~0.90 g/cm³ |
| Tensile strength (MD) | 25–35 MPa |
| Stiffness (vs. rPE) | Noticeably higher; holds shape unsupported |
| Heat-seal window | 130–165 °C (narrower than PE — line setup matters) |
| Service temperature | −10 to +100 °C |
| Moisture barrier | High |
| Oxygen barrier | Low |
| Clarity | Semi-transparent; haze rises with PCR % |
Typical values — customizable to spec. Final parameters are confirmed against your product, filling line and test protocol.
The practical difference buyers notice first: rPP bags stay open and upright during manual packing, and they withstand warmer filling environments where PE would begin to soften.
Fit check
Where Recycled PP (rPP) Performs — and Where It Doesn't
Strong fits
- Garment and apparel packaging — stiff, crease-resistant bags and sleeves for clothing, textiles and accessories; see branded packaging programmes.
- Document and stationery sleeves — shape retention protects contents in transit; see flat bag formats.
- Rigid-feel retail bags — a premium hand-feel at plastic-bag cost, with PCR content supporting PPWR reporting; see carrier bag formats.
- Warmer filling environments — service temperature to ~100 °C covers applications PE cannot.
Honest limitations
— The seal window is narrower and hotter than PE — we validate seal settings on your filling line before production.
— rPP is more brittle at deep-freeze temperatures; for frozen goods below −10 °C, consider rPE or a coex structure.
— Like all PCR films, clarity decreases as recycled content rises; 100% PCR rPP is not crystal-clear.

Buyer questions
Frequently Asked Questions
Decide by stiffness and temperature. If the bag must hold its shape, hang, or resist creasing — or if your filling environment exceeds ~70 °C — choose rPP. If you need the widest seal window, the lowest cost, or deep-freeze performance, choose rPE. Send us your product and packing method; an engineer will confirm the choice with samples.
Where certified feedstock allows, yes — but we recommend validating optics and mechanicals with samples first, as high-PCR rPP shows more haze and gel specks than high-PCR rPE. Most retail programmes run 30–70% PCR as the practical balance.
