Format selection
Choose the right poly bag structure
What should you consider first?
Application & clarity: Do you need crystal-clear transparency for retail display or lightweight protection for warehouse fulfilment?
Gauge & film thickness: Retail inner bags typically run lighter gauges, while heavy-duty protective shipping bags require higher puncture resistance. Your converter will confirm the right spec for your fill weight and line speed.
Closure & opening: Choose between standard self-seal adhesive strips, resealable slider/zippers, or open top for heat sealing.
Fulfilment automation: Do you require loose bags, wicketed bags, or autobagger continuous rolls for automated high-speed packing lines?
How to choose between PCR poly, compostable, and glassine bags?
It comes down to three questions: what your brand is optimising for, where you are selling, and what your customers will do with the packaging after it arrives.
Choose recycled content poly (PCR) if:
- Reducing carbon footprint is your primary sustainability metric.
- You are optimising for cost, high clarity, and freight efficiency.
- You run automated fulfilment lines requiring autobagger-compatible films.
Choose certified compostable film if:
- A certified compostable, lower-fossil-feedstock story is central to your brand.
- You have confirmed home or industrial composting infrastructure exists in your key markets. The end-of-life benefit depends on the pack actually reaching a composter.
Choose glassine paper if:
- A completely plastic-free unboxing experience is a non-negotiable part of your brand story.
- You want a smooth, translucent finish that works beautifully for garment and premium product presentation.
- You are running a high-volume program. Glassine is available on select custom projects; speak to us about whether it's the right fit for your volume and application.
Why Grounded
Custom sustainable poly bags engineered for impact
100% recycled, fully certified, at any scale
GRS-certified post-consumer recycled film, at 100% recycled content as standard rather than a premium tier. Supplied as standard bags or as fan-folded rolls for autobagger lines, running at full line speed without dropping recycled content. If you are currently specified at 30% or 50% post-consumer, this is the step up, with the chain-of-custody documentation to prove it when your retail buyer asks.
Multi-country fulfilment architecture, built around where you sell
Production and shipping built around how brands actually operate. Bags can ship direct to your DCs or sit in managed warehouses across several markets at once, drawn down as you need them rather than landing as one annual order you have to store and fund upfront. With local warehousing and regulatory teams across key regions, your packaging is specified for the market it lands in.
Data-driven sustainable packaging
Scope, our Packaging LCA platform, reports carbon footprint and Material Circularity Indicator side by side for every material option, cradle to grave. On PCR poly versus virgin, the carbon difference is material. We show you the numbers, the assumptions behind them, and where the real impact sits.
Print quality and customisation as brand leverage
Fully custom is our default. Printed bags are a brand touchpoint, not a packing cost. Grounded focuses on print quality, colour accuracy and tactile finish, printing with water-based inks certified to REACH and ROHS. Add branding, sizing indicators, barcode panels or multilingual suffocation warnings, specified at artwork stage rather than stickered on afterwards. Bring us your current bag and we will match size, gauge and finish.

Frequently asked questions
What is the difference between recycled content poly bags and compostable poly bags?
+
Recycled content poly bags are made from post-consumer recycled plastic and designed to re-enter soft-plastic recycling streams where collection infrastructure exists. Compostable poly bags are certified to break down in home or industrial composting environments. Compostable poly bags rely on distinct waste pathways and cannot go in the same disposal bin as recycled poly.
Can I print custom logos and suffocation warnings on poly bags?
+
Yes. Grounded offers custom printing using water-based, REACH and ROHS certified inks. Add brand graphics, sizing charts, barcodes, and required safety and suffocation warning text in multiple languages.
Are Grounded’s poly bags suitable for automated packaging lines?
+
Yes. We produce wicketed bags and fan-folded autobagger rolls engineered to run at high line speeds on automated packing machinery, including in GRS-certified 100% PCR film.
What thickness (gauge) do I need for garment packaging?
+
Gauge depends on your product weight, fill method, and line requirements. Lighter garments typically need less protection than outerwear or heavy-duty shipping bags. Speak to us and we will confirm the right spec for your application.
Are glassine paper bags a direct replacement for poly bags?
+
For the right application, yes. Glassine offers a premium, translucent, plastic-free alternative with excellent dust protection and a clean unboxing finish. It has lower water resistance than poly, so it suits dry inner garment packaging best. Glassine is available on select high-volume custom projects; speak to us about fit for your programme.
What is the minimum order quantity (MOQ) for custom poly bags?
+
Our line minimum for custom poly bags is 100,000 units per unique size or design. This reflects our supplier line structure, not an industry floor, and exists to deliver the unit economics that make a custom certified programme worthwhile. If you are below that volume today, speak to us: size consolidation or a phased programme can often bridge the gap.
