For procurement teams facing ESG, EPR and sustainability requirements, choosing RPET isn’t simply about selecting the highest recycled content. The right percentage depends on your product, regulations, cost targets, and customer expectations.
Why This Guide Matters
Across Europe and North America, sustainability requirements are no longer optional.
Retailers, food brands, and packaging companies are increasingly asked to demonstrate:
- Reduced virgin plastic consumption
- Verified recycled content
- ESG reporting
- EPR compliance
- Supply chain transparency
Many buyers immediately ask for 100% RPET, believing it is always the best solution.
In reality, that’s not always true.
For thermoforming packaging, 30%, 50%, and 100% RPET each have different advantages, and the best choice depends on the application.
This guide explains the differences from the perspective of a thermoforming sheet manufacturer.
Quick Comparison
| Item | 30% RPET | 50% RPET | 100% RPET |
|---|---|---|---|
| Virgin PET Content | 70% | 50% | 0% |
| ESG Performance | ★★★★☆ | ★★★★★ | ★★★★★+ |
| Mechanical Strength | Excellent | Excellent | Very Good |
| Optical Clarity | Excellent | Excellent | Good–Excellent |
| Price Stability | Highest | High | Depends on RPET market |
| Food Packaging | Excellent | Excellent | Widely Used |
| Recommended For | Large-volume production | Mainstream retail packaging | Strong sustainability positioning |
What Does RPET Percentage Mean?
Many buyers misunderstand recycled content.
30% RPET means approximately 30% of the raw material comes from recycled PET, while the remaining portion is virgin PET resin.
Likewise:
- 50% RPET = Half recycled
- 100% RPET = Fully recycled PET (excluding functional additives)
Higher recycled content does not necessarily mean lower quality.
Modern co-extrusion technology allows RPET sheet to maintain excellent:
- Impact strength
- Thermoforming performance
- Food safety
- Printability
- Transparency
When Should You Choose 30% RPET?
Stable Production
Excellent consistency for large production volumes.
Competitive Cost
Lower material fluctuation than fully recycled content.
Excellent Appearance
High transparency and gloss.
Easy Processing
Suitable for demanding thermoforming applications.
Typical applications:
- Fresh produce trays
- Bakery packaging
- Disposable food trays
- Electronics blister packaging
- Cosmetic inserts
Ideal for buyers who need sustainability while maintaining maximum production efficiency.
When Should You Choose 50% RPET?
Many international retailers specify around 50% recycled content.
Reasons include:
- Better ESG reporting
- Easier supplier qualification
- Strong environmental messaging
- Good balance between cost and sustainability
It is one of the most popular choices for:
- Supermarkets
- Food brands
- OEM packaging suppliers
- Export packaging
When Is 100% RPET the Best Choice?
100% RPET is often selected when sustainability is a core selling point.
Examples include:
- Premium eco brands
- Organic food packaging
- Sustainable takeaway packaging
- Retailers with aggressive carbon reduction goals
Benefits include:
- Maximum recycled content
- Strong marketing value
- Supports circular economy initiatives
- Lower virgin plastic consumption
However, buyers should ensure:
- Stable raw material supply
- Consistent color
- Certified production
- Reliable quality control
Typical Applications
RPET sheet is widely used for:
- Fresh fruit trays
- Vegetable packaging
- Bakery containers
- Sushi trays
- Ready meal trays
- Chocolate boxes
- Cosmetic blister packaging
- Electronics trays
- Toy packaging
- Medical thermoforming packaging
GRS Certification Explained
Many buyers confuse RPET with GRS Certified RPET.
They are not the same.
| RPET Material | GRS Certified RPET |
|---|---|
| Contains recycled material | Verified recycled content |
| Material only | Entire supply chain audited |
| No traceability required | Full chain of custody |
| No social/environmental audit | Environmental & social compliance |
| Suitable for general use | Preferred by international brands |
If your customer specifically requests GRS, your supplier must hold a valid certification covering the relevant products and production process.
Why GRS Matters for ESG & EPR
GRS certification helps procurement teams demonstrate:
- Traceable recycled materials
- Responsible sourcing
- Supply chain transparency
- ESG reporting support
- Customer sustainability audits
- Reduced compliance risk
For many multinational brands, GRS documentation simplifies supplier approval and annual sustainability reporting.
Procurement Checklist
Before Ordering RPET Sheet
- ☑ Confirm required recycled content
- ☑ Ask whether GRS certification is available
- ☑ Verify food-contact compliance
- ☑ Check thickness tolerance
- ☑ Review thermoforming performance
- ☑ Confirm color consistency
- ☑ Request production samples
- ☑ Verify annual production capacity
- ☑ Confirm lead time
- ☑ Review export experience
RPET vs Virgin PET
| Feature | Virgin PET | RPET |
|---|---|---|
| Transparency | Excellent | Excellent |
| Sustainability | Standard | Excellent |
| Carbon Footprint | Higher | Lower |
| Circular Economy | No | Yes |
| ESG Reporting | Limited | Strong |
| EPR Support | Limited | Better |
| Customer Preference | Traditional | Increasingly Preferred |
Why Choose a GRS-Certified RPET Sheet Supplier?
Working with an experienced manufacturer provides more than just recycled material.
Look for suppliers that can offer:
- Stable recycled content options (30%, 50%, 100%)
- Consistent thermoforming performance
- Food-contact compliant materials where required
- In-house quality inspection
- Batch traceability
- Custom thickness and width
- Export packaging experience
- Technical support for new projects
This helps reduce sourcing risk while supporting long-term sustainability goals.
Frequently Asked Questions
Is 100% RPET always better than 50% RPET?
Not necessarily. While 100% RPET maximizes recycled content, 50% RPET may offer a better balance of cost, appearance, supply stability, and sustainability for many packaging applications.
Can RPET sheet be used for food packaging?
Yes. RPET sheet can be used for many food packaging applications when produced in compliance with applicable food-contact regulations and customer requirements.
Does GRS certification guarantee food safety?
No. GRS verifies recycled content and supply chain traceability. Food-contact compliance depends on the material formulation and the relevant regulatory approvals.
Is RPET more expensive than virgin PET?
Pricing depends on recycled resin availability, market demand, and recycled content. In some periods, RPET may cost more than virgin PET, while at other times the difference is minimal.
What recycled content do supermarkets usually require?
Requirements vary by retailer and region. Many supermarket programs specify minimum recycled-content targets, while others focus on verified sustainability credentials such as GRS certification.
Can RPET be thermoformed like virgin PET?
Yes. High-quality RPET sheet offers excellent thermoforming performance and is widely used for trays, clamshells, and blister packaging.
Final Thoughts
For most buyers, the decision isn’t simply between virgin PET and recycled PET—it’s about selecting the right recycled content to meet performance, budget, and sustainability goals.
- 30% RPET is a practical choice for stable production and cost control.
- 50% RPET offers an excellent balance between ESG performance and manufacturing consistency.
- 100% RPET is ideal for brands prioritizing maximum recycled content and strong environmental messaging.
When evaluating suppliers, don’t focus solely on recycled content. Consider manufacturing capability, quality consistency, traceability, and whether the supplier can support your long-term sustainability strategy with reliable documentation and production experience.
