Strong Blue Mailing Bags for Ecommerce and Retail
Give customer orders a bright, professional finish with Spectrum® Sky Blue Mailing Bags. Designed for ecommerce, mail order and retail dispatch, these strong yet lightweight polythene mailing bags help protect non-fragile goods from dirt, splashes and everyday handling during delivery.
Each bag is manufactured from durable 50 micron (200-gauge) polythene and features a permanent peel-and-seal adhesive strip. Once closed, the seal is tamper-evident, helping you pack and dispatch customer orders quickly and securely.
The smooth outer surface is suitable for courier labels, address labels and handwritten delivery information. The vibrant sky blue finish also offers a cost-effective way to coordinate your shipping packaging with your brand colours without ordering fully custom-printed mailing bags.
