Who This Guide Is For
This article is written for apparel exporters, fashion brand procurement managers, and sourcing agents who are transitioning their garment packaging to certified recycled materials. If you export clothing to European, North American, or Japanese markets — and your buyers are increasingly requesting GRS-certified packaging as part of sustainability requirements — this guide will help you specify and source the right bags.
Why GRS Certified Garment Bags Matter Now
The Global Recycled Standard (GRS) is the world's leading voluntary certification for recycled content across the entire supply chain. Since 2024, major retailers in the EU and US — including H&M, Inditex (Zara), and Uniqlo's supply chain — have mandated GRS documentation for all plastic packaging materials. Without a valid GRS Transaction Certificate (TC), recycled content claims cannot be made on commercial invoices or product listings.
For apparel exporters, GRS-certified recycled PE garment bags are no longer an optional upgrade — they are a competitive necessity that directly impacts order wins, especially from brands with public ESG commitments and mandatory 2030 recycled content targets under the EU PPWR (Regulation (EU) 2025/40).
Recommended Product: GRS Recycled PE Garment Bags
Xiahong Packaging manufactures the full range of GRS-certified recycled polyethylene garment bags, from standard open-ended bags to custom-printed options with up to 6-color flexographic printing. All products come with full chain-of-custody documentation.

| Certification | GRS (Global Recycled Standard), verified by independent audit bodies (e.g., Control Union, EcoCERT) |
| Film thickness | 0.03mm - 0.06mm (30-60 microns), customizable |
| Bag format | Open-ended (open-end), self-adhesive (pressure-sensitive), slider/zipper closure |
| Print | 1-6 color flexographic printing, water-based inks |
| Size range | Standard sizes (30x40 cm to 70x100 cm); fully custom dimensions available |
| Surface finish | Matte (natural recycled appearance), anti-static option |
| Compliance | REACH, FDA food-contact (if applicable), EU PPWR design-for-recyclability ready |
See our GRS Garment Bag catalog for the full product range.
How PCR Content Levels Affect Performance
The percentage of post-consumer recycled content has practical implications for bag performance:
- 30% PCR - Closest appearance to virgin PE; suitable for light garments, good cost-to-performance ratio. Recommended for first-time adopters.
- 50% PCR - Balanced option with noticeable recycled content. Slight darkening of the film (grayish tint). Best for mid-weight garments like T-shirts and blouses.
- 70-100% PCR - Fully recycled material with maximum environmental benefit. Film has a distinct gray tone. Recommended for premium sustainability claims. Performance is equal to or better than virgin PE in tensile strength and seal integrity.
Thickness Selection Guide for Garment Types
| Garment Category | Recommended Thickness | Rationale |
|---|---|---|
| Lightweight: T-shirts, tank tops, underwear | 0.03-0.04mm (30-40 um) | Cost-effective, sufficient for low-weight items |
| Medium: Denim, sweaters, dresses, casual shirts | 0.04-0.05mm (40-50 um) | Good balance of protection and material cost |
| Heavy: Overcoats, wool suits, winter jackets | 0.05-0.06mm (50-60 um) | Extra strength for heavy, high-value garments |
| Multi-pack bundles | 0.05-0.07mm (50-70 um) | Reinforced for combined weight of multiple items |
Documentation and Compliance Checklist
When sourcing GRS garment bags, request the following documentation from your supplier:
- GRS Transaction Certificate (TC) - Every shipment must be accompanied by a TC that matches the order quantity and PCR content percentage. The TC links back through the certified supply chain to the recycled material source.
- GRS Scope Certificate - Confirms the supplier is actively certified. Valid for one year with annual surveillance audits.
- Material Safety Data Sheet (MSDS) - Required for customs clearance in many markets.
- REACH Declaration - Confirms absence of substances of very high concern (SVHC).
- Certificate of Analysis (COA) - Reports on tensile strength, seal strength, and thickness tolerance.
- Chain-of-Custody Records - For brand transparency reporting and EPR compliance.
Pre-Order Verification: 10 Questions for Your Supplier
| # | Question | Why It Matters |
|---|----------|----------------|
| 1 | Is the TC number issued by an accredited body (Control Union, SGS, EcoCERT)? | Verifies the certification is legitimate and internationally recognized |
| 2 | What is the exact PCR percentage? | 30% PCR vs. 100% PCR significantly affects cost, film appearance, and buyer claims |
| 3 | Can the PCR percentage be specified per order batch? | Some brands require consistent PCR across all packaging components |
| 4 | What are the thickness tolerance specifications? | Industry standard is +/-10%; tighter tolerances cost more |
| 5 | Do you use water-based inks for all printing? | Required for environmental claims and EU compliance |
| 6 | What is the film opacity? | Recycled PE has a natural grayish tint - important for light-colored garment visibility |
| 7 | What is the seal strength of the self-adhesive closure? | Must hold garment weight during transit; typical minimum 15 N/25mm |
| 8 | What is the sample lead time and cost? | Physical validation of fit, closure integrity, and print quality is essential |
| 9 | Can you provide a GRS Transaction Certificate for the sample shipment? | Ensures the sample itself is from certified recycled material |
| 10 | What is the EPR registration support for EU market access? | Many European buyers require their supplier to assist with packaging EPR reporting |
