Advancing Rigid Packaging with Up to 70% PCR

GCR and CurTec validated CICLICNXT® rHDPE solutions for injection and blow molding applications, supporting high PCR content, smooth processing, and lower CO2 impact in rigid packaging.

Challenge

CurTec had established specific recycled content levels across its rigid packaging range, with 50% PCR for injection-molded formats and 70% PCR for blow-molded applications.
Specifically, the challenge was clear: integrate high PCR levels without affecting technical requirements. Processability for industrial production had to remain intact.

Key Results

Blow Molding

• 70% PCR content validated
• 65% CO₂ reduction vs. virgin HDPE

Injection Molding

• 50% PCR content validated
• 45% CO₂ reduction vs. virgin HDPE

Processing

• Virgin-like behaviour
• Smooth and stable processability

Solution

GCR partnered with CurTec to validate CICLICNXT® rHDPE as a high-PCR content solution for rigid packaging in injection and blow molding, selected for its controlled feedstock, high cleanliness, and reliable processability.

Validated scope:

• Injection molding: lids and drums with 50% PCR content
• Blow molding: drums with 70% PCR content

As a result, this validation confirmed the suitability of CICLICNXT® rHDPE across multiple high-PCR rigid packaging formats at CurTec.

PPWR Relevance PPWR is increasing the focus on minimum recycled content in plastic packaging. In fact, this case shows that high PCR levels can already be integrated into demanding rigid packaging formats with the process efficiency needed to support practical readiness.

GCR and CurTec demonstrate that CICLICNXT® rHDPE can support high-PCR rigid packaging for demanding applications, with the reliability and processability required for industrial production.
