Looking for GRS recycled plastic bags or shrink films that help you meet global sustainability rules?
Here’s the simple truth: brands and importers are under pressure to use recycled packaging — and the fastest way to stay compliant is choosing packaging with verified recycled content and valid TC certificates.
This guide breaks everything down in a clean, buyer-friendly way, so you can choose the right GRS products without confusion.
1. What Makes Packaging “GRS Certified”?
GRS (Global Recycled Standard) is the most recognized international certification for recycled materials.
A product is considered GRS compliant ONLY when:
It contains verified recycled content (30% / 50% / 70% / 100%)
Each batch has a TC Certificate (Transaction Certificate)
The supply chain is audited from raw material → factory → shipment
In short: the factory certificate shows capability;
the TC certificate proves your goods are real.
2. PCR vs PIR — What’s the Difference?
PCR (Post-Consumer Recycled)
Comes from used plastic bags collected after consumer use.
Features:
Slightly darker transparency
More environmentally meaningful
Helps buyers avoid plastic taxes in many countries
PIR (Pre-Consumer Recycled)
Comes from production scrap collected before reaching consumers.
Features:
Cleaner, clearer
More stable quality
Lower cost than PCR
➡️ Both PCR and PIR are recognized by GRS.
➡️ Both count toward the “30% Recycled” requirement.
3. Why Do Buyers Choose GRS Recycled Packaging?
✔ Helps avoid plastic taxes in EU, UK, Italy, Spain
✔ Matches brand sustainability requirements
✔ Reduces carbon footprint
✔ Accepted by major brands (apparel, electronics, logistics, FMCG)
✔ Provides traceability with TC certificates
For importers and wholesalers, GRS bags are no longer “a nice option” —
they’re becoming mandatory.
