Description

Not every parcel needs to shout. Dark Grey LDPE Mailing Bags are the dependable, no-nonsense choice for sellers who ship in volume and want packaging that's secure, discreet and easy on the budget. The neutral grey exterior looks smart and professional, while the black inner layer hides contents completely, protecting customer privacy and deterring tampering.

Made from strong co-extruded polythene at around 55 micron (220 gauge), they're waterproof, tear-resistant and built to handle the rough and tumble of the postal network. The 50mm peel and seal strip creates a permanent, tamper-evident closure in seconds with no tape required, keeping packing fast and consistent on even the busiest dispatch days.

With 11 sizes designed around Royal Mail formats, from a 6" x 9" letter bag for small accessories, through large letter and small parcel sizes for clothing and homewares, up to 24" x 36" for bedding, bulky garments and multi-item orders, plus a 6" x 34" tube format for posters and rolled items, there's a fit for almost anything you sell.

Lightweight to keep postage costs down and 100% recyclable, they're a staple for eCommerce businesses, fashion brands, marketplace sellers and fulfilment houses. Available from a single sample through to packs of 10, 50, 100 and boxes of up to 2,000.
