Strong 60 µm Eco Postal Bags – Blue 10×14"
The co-extruded 60 µm film resists tears and scuffs, the permanent peel-and-seal bonds fast, and the opaque blue finish gives a clean, professional look that stands out in transit and on the doorstep.
Why this 10×14" size?
10×14" is the everyday “small-order” workhorse. It fits folded T-shirts, paperbacks and smaller boxed goods while keeping parcels compact for cheaper postage bands. The blue colour adds a fresh, branded feel without the cost of custom print.
Real use examples
- Folded T-shirts and light tops
- Books, stationery and small gift sets
- Phone cases, cables and accessories
- Cosmetics kits and sample packs
Fit & packing guidance
Best for contents up to approx. 235×330×40 mm. If tight, step up to 12×16". Round or pad inner-box corners and press out air before sealing for a flatter parcel and lower postage volume.

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).
Strength & Protection
Durable co-extruded film helps resist tears and punctures, while the tamper-evident seal protects orders in transit. Opaque blue film ensures privacy.
Storage & Performance
Store flat between 13–21 °C away from heat/sunlight. Let cold stock acclimatise before use for a reliable adhesive bond.
