Why choose this 10×14" size?
This 10×14" (254×355 mm) size is one of the most popular everyday mailing sizes used by online retailers. It offers more internal length than 9×12", which gives better room for folded clothing, padded items and small boxed goods. This reduces seam stress, prevents bursting during transit and makes packing quicker and cleaner. The premium purple colour also improves customer presentation, making it ideal for brands who want parcels to look professional and consistent across marketplaces like Shopify, Etsy, TikTok Shop, Amazon and eBay.
Real use examples
- 1–2 folded T-shirts (S–XL), leggings or a lightweight jumper
- Paperback book with card backing or corner pads
- Small gift item in a compact retail box
- Cosmetics bundle or accessories order
- Online boutique orders with return slips
- Subscription products or sample packs
Fit & packing guidance
This mailing bag works best with soft goods up to 240×330×40 mm. Always press out excess air before sealing to keep parcels compact and reduce Royal Mail postage costs. For larger jumpers or products requiring added packaging space, move up to 12×16". If posting a single lightweight item such as a T-shirt or paperback, step down to 9×12" for a more secure, fitted pack.

Eco & materials
These bags are made using 100% recycled LDPE (code 4). This material is durable, flexible and tear-resistant, yet can still be recycled again where soft plastic collection is available. These are not biodegradable or compostable bags, but they are a more responsible alternative to virgin plastic mailing bags. Choosing recycled LDPE helps reduce landfill waste and supports a circular material economy.
Strength & protection
The 60 µm film thickness provides a higher level of tear and puncture resistance compared to standard grey mailers. This makes them suitable for clothing brands, online gift stores, subscription services and fulfilment centres that require strong, dependable packaging for daily use. The permanent self-seal adhesive strip prevents tampering and accidental opening during transit.
Storage & performance
For best results, store mailing bags at 13–21°C in a dry environment away from direct sunlight. If stored in a cold warehouse, allow the adhesive strip to reach room temperature before use to maintain seal strength.
Lightweight = Lower Postage Costs
Compared with cardboard boxes, mailing bags reduce parcel weight, helping businesses ship orders more cost-effectively with Royal Mail, Evri, DPD, Yodel and other couriers. The slim format helps stay within Large Letter and Small Parcel size limits where possible.
