Grey Mailing Bags 24×36" (610×914 mm) – maximum capacity, quick and clean to pack
Grey mailing bags 24×36" (610×914 mm) give you the space for very large textiles, pillows and bedding, and big retail boxes while keeping parcels lightweight. Made from tough 60-micron recycled LDPE, they are moisture-proof (water-resistant), opaque for privacy, and close in seconds with a self-seal strip.

Why choose this 24×36" size?
When 20×26" or 21×24" start to strain, 24×36" adds the length and width needed for duvet sets, bulk throws, pillows and larger boxed goods—without jumping straight to heavy cartons. The neutral grey finish presents well, hides contents, and resists scuffs in transit.
Real use examples (what typically fits)
- Textiles & home: duvet sets, pillows, large throws, curtains, bulky bedding in sleeves.
- Apparel & kits: multi-item clothing bundles, coats with inner wraps, subscription kits.
- Boxed goods: large retail boxes, gift sets and components with inner padding.
Fit & packing guidance
- Best fit: very large textiles, big soft goods, large boxed items with rounded corners.
- Too tight? Step up to 28×30" or 28×34".
- Too roomy? Step down to 20×26" or 21×24" for a neater seal and lower postage.
- Corner care: pad sharp inner-box edges to reduce punctures.
- Press out air: flatten before sealing so labels sit flat and sacks/totes stack cleanly.
Key benefits
- Self-seal, tamper-evident closure for rapid packing.
- 60-micron co-extruded film helps resist tears, splits and scuffs.
- Moisture-proof / water-resistant outer for wet routes.
- Opaque grey for privacy and a clean, uniform look.
- Recyclable LDPE — remove the glue strip before recycling.

Eco & Materials
Material: 100% recycled LDPE (resin code 4), co-extruded for strength and opacity. Recyclable in many UK schemes — please remove the adhesive strip first. Not biodegradable or compostable.
Strength & Protection
60-micron film is puncture- and tear-resistant and moisture-proof. The self-seal, tamper-evident adhesive forms a permanent bond once pressed.
Storage & Performance
Store at 13–21 °C and out of direct heat/sunlight. Let cold stock acclimatise before use to maintain adhesive performance.
Lightweight = Lower Postage
Recycled LDPE mailers are exceptionally lightweight, helping you keep parcels in lower weight bands versus boxes.
