Description

Purple has always signalled something a little special, and Purple Polythene Mailing Bags bring that feeling to every delivery. Ideal for beauty, jewellery, gift and premium fashion brands, the rich colour makes parcels instantly recognisable, while the opaque black inner layer keeps contents completely private from dispatch to delivery.

Made from strong co-extruded polythene at 55 micron (220 gauge), they're waterproof, tear-resistant and built to withstand the knocks of the postal network. The 40mm peel and seal strip forms a permanent, tamper-evident closure in seconds, with no tape or tools needed, keeping packing fast whether you're sending a handful of orders or a full day's dispatch.

Five sizes align with Royal Mail formats, from a 6.5" x 9" letter bag for jewellery and accessories, through 9" x 12" and 10" x 14" large letter sizes for t-shirts and lightweight clothing, up to 12" x 16" small parcels and 16" x 21" medium parcels for jumpers, shoes and multi-item orders. Blue and pink versions are also available for colour-coding or brand matching.

Light enough to keep postage down and 100% recyclable, they're a favourite with boutiques, marketplace sellers, subscription boxes and creative small businesses. Available from a single bag through to packs of 10, 50, 100 and boxes of up to 2,000.
