A garment poly bag is more than a printed brand logo. In export orders to Europe and the US, the front carries the brand image while the side or back must fit recycling marks, warnings, origin, barcode and batch info — miss one item and the shipment can be rejected; misplace one and scanning or looks suffer. This garment poly bag marking guide covers what to print, where to put it, how to print it and what to send when ordering.
A practical rule: split the bag surface into three layers — regulatory and required, product and logistics, brand and marketing — and confirm each layer before finalizing the layout so nothing gets missed.
1. Three Layers of Information: Sort Before You Design
| Layer | Contents | Layout Priority |
|---|---|---|
| Regulatory & required | Recycling triangle and resin code, suffocation warning, country of origin, eco or recycling claims required by the buyer | Check every item against the buyer spec and destination-country rules — none may be skipped |
| Product & logistics | Barcode (EAN/UPC), style, color, size, quantity, batch number and similar | Keep the barcode area scannable and clear of sealing and stretch zones |
| Brand & marketing | Brand logo, tagline, social handles, website, opening instructions | Subordinate to overall design; never hurts readability of functional info |
2. Recycling Triangle and Resin Code: the Code Follows the Material
Plastic packaging often carries a recycling triangle with a 1–7 resin code identifying the material for sorters. For garment bags the mapping is roughly: PE bags (HDPE/LDPE) use code 2 or 4, PP bags code 5, and OPP is a PP film. The code must match the actual material — a wrong code can be treated as misleading labeling in some markets.
Markets such as the EU are tightening rules on recyclability-by-design, marking and environmental claims for plastic packaging (for instance under the packaging and packaging waste regulation, phased in over years). Rules differ by product category and bag size. Rely on the buyer's written specification and ask them to supply the required mark style and placement where needed.
3. Suffocation Warning: a Common Export Requirement
Bags with a large opening generally need a suffocation warning in European and American markets, typically worded like 'To avoid danger of suffocation, keep away from babies and children', often with a pictogram showing the bag must not cover a baby's face. The wording, font size and placement are usually set by the buyer spec — commonly on the front of the bag or near the seal.
4. Barcode and Product Info: Scan First, Looks Second
- The barcode symbology and data come from the buyer or channel (EAN/UPC for example) — confirm the coding rules before printing
- Give the barcode a clean white background with a quiet zone; avoid heat-sealed areas, stretch zones and creases
- Keep high contrast between the ink and the film; on dark bags place the barcode on a white patch
- Lay out fields like style, color, size and quantity at consistent sizes and positions per the buyer spec so warehouses can check them quickly
5. Choosing the Printing Method: Direct Print, Label or Foil
The more and finer the markings, the more the print method matters for clarity and durability. PE and PP films have low surface energy and usually need corona treatment before printing so the ink adheres; small runs with many designs often use adhesive labels to avoid plate costs per design, while direct printing is more economical for large runs of one layout. Foil stamping suits metallic accents, not large areas of fine text.
6. Send a Marking Checklist with Your Order
- The full list of markings: every item (logo, recycling mark, warning, origin, barcode, batch, etc.) with its language
- A placement diagram: which item goes on which panel and area of the bag (front, back, side, above the seal, etc.)
- Raw barcode data and format requirements (symbology, digits, whether a human-readable line is needed)
- Destination country and sales channel, so the supplier can double-check standard marking practice and flag risks
- Material and specs: bag style, size, gauge and material — because the resin code must match the material
7. One Wrong Proof, One Full Rerun: Approve Before Printing
Rework on bag markings is expensive: a change means new plates or film, and scrapping a whole batch is not rare. Confirm the marking list, layout and barcode data before sampling, and only run bulk after sample approval — that saves the cost of a full batch and three-plus weeks of time.
