Why this 10×14" size?
10×14" is the everyday “small order” workhorse. Compared with larger bags, it cuts void space and helps keep parcels in cheaper Royal Mail bands. It’s perfect for folded T-shirts, books, cosmetics kits and small boxed goods. The fresh green colour underscores your sustainability message while giving a tidy, professional finish at the door.
Real use examples
- One folded T-shirt or lightweight top
- Paperback or small hardback with card backing
- Cosmetics bundle, small accessories or craft items
- Spare parts, electronics accessories or cables
Fit & packing guidance
Best internal fit up to approx. 240×330×40 mm. Choose the smallest bag that closes flat across the seal. If the adhesive lip lands on a bulge, step up to 12×16". Add simple corner pads for sharp edges, and press out excess air before sealing to keep parcels compact.
Key benefits
- Eco premium: 60 µm film made from 100% recycled LDPE (code 4)
- Moisture-proof / water-resistant for everyday courier handling
- Fully opaque green for privacy and a clean, sustainable look
- Fast peel-and-seal – permanent, tamper-evident bond, no tape needed
- Lightweight to reduce postage versus cartons
- Recyclable at carrier-bag return points (LDPE code 4)
Available pack sizes
Choose the right volume for your workflow:
- Pack of 100 – ideal for small sellers and trials
- Pack of 300 – steady weekly dispatch
- Pack of 500 – growing stores and multi-channel sellers
- Pack of 1000 – best unit cost for high-volume fulfilment
Eco & materials
These mailers use co-extruded recycled film that balances strength and resource efficiency. Using recycled LDPE helps close the loop while delivering reliable tear and puncture resistance. Not biodegradable or compostable; please recycle via carrier-bag return schemes where available.
Strength & protection
At 60 µm, the film resists scuffs and handling damage better than economy grades. The permanent adhesive creates a tamper-evident seal that stays shut through sorting and last-mile delivery. The opaque green film protects buyer privacy.
Storage & performance
Store flat at 13–21 °C away from heat and direct sun. If stock arrives cold, allow it to reach room temperature before use for a consistent seal.
Lightweight = lower postage
Mailing bags cut dead weight versus cartons and help keep dimensions inside cheaper bands with Royal Mail, Evri and other couriers. Use a slim inner box or corner pads only when presentation or sharp edges require it.
