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.

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 ไม่ necessarily mean lower quality.
Modern co-extrusion technology allows RPET sheet to maintain excellent:
- ความแข็งแรงของผลกระทบ
- ประสิทธิภาพการขึ้นรูปด้วยความร้อน
- Food safety
- Printability
- ความโปร่งใส
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
- บรรจุภัณฑ์เบเกอรี่
- Disposable food trays
- บรรจุภัณฑ์พุพองอิเล็กทรอนิกส์
- 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:
- ซุปเปอร์มาร์เก็ต
- Food brands
- OEM packaging suppliers
- บรรจุภัณฑ์ส่งออก
When Is 100% RPET the Best Choice?
100% RPET is often selected when sustainability is a core selling point.
ตัวอย่างได้แก่:
- 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
- ลดการใช้พลาสติกบริสุทธิ์
However, buyers should ensure:
- Stable raw material supply
- Consistent color
- Certified production
- Reliable quality control
แอปพลิเคชันทั่วไป
RPET sheet is widely used for:
- Fresh fruit trays
- Vegetable packaging
- ภาชนะใส่เบเกอรี่

GRS Certification Explained
Many buyers confuse rpet กับ GRS Certified RPET-
พวกเขาเป็น 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 | ด้านสิ่งแวดล้อม & 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
- การตรวจสอบความยั่งยืนของลูกค้า
- Reduced compliance risk
For many multinational brands, GRS documentation simplifies supplier approval and annual sustainability reporting.
