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.

Specifications

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.
