Strong 60 µm Eco Postal Bags – Blue 17×22"
Durable co-extruded 60 µm film helps resist tears and punctures, the permanent peel-and-seal strip gives a fast, tamper-evident close, and the opaque blue finish delivers a clean, professional look at the doorstep.
Why this 17×22" size?
17×22" is the go-to for bedding, winter coats, large hoodies, cushions and bigger gift boxes. It keeps soft goods protected while staying lighter than outer cartons, helping control postage bands and warehouse space.
Real use examples
- Bedding sets, pillows and throws
- Coats, puffers and bulky apparel
- Multiple-item clothing bundles
- Larger gift boxes and soft homeware
Fit & packing guidance
Best for contents up to approx. 410×540×120 mm. If your item exceeds this, consider an outer box. Pad inner-box corners, and press out air before sealing for flatter parcels and cleaner labels.
Will it split? No — the co-extruded 60 µm film resists bursting even with bulky items like coats or bedding. It flexes instead of tearing under pressure during courier handling.
Key benefits
- Strong self-seal – permanent, tamper-evident bond
- 60 µm recycled LDPE – tear/puncture resistance
- Moisture-proof / water-resistant outer
- Opaque blue – privacy and brand presence
- Lightweight – helps reduce courier/Royal Mail costs
- Recyclable LDPE (code 4) – return-to-store schemes
Eco & Materials
Made from 100% recycled LDPE to reduce virgin plastic use. Not biodegradable or compostable. Recycle via soft-plastic return schemes (remove the glue strip). It’s made from recycled film and is recyclable again through most supermarket return points.
Strength & Protection
Co-extruded film for toughness, tamper-evident adhesive for security, and a fully opaque finish for customer privacy.
Storage & Performance
Store flat between 13–21 °C and away from direct heat/sunlight. Allow cold stock to acclimatise before sealing for best adhesive performance.
Lightweight = Lower Postage
Mailing bags weigh less than cartons, helping you stay in lower weight bands while protecting soft goods and slim boxed items.
