Buyer's Guide
Looking for grey mailing bags, postal bags or poly mailers? These strong self seal parcel bags are the everyday choice for posting clothes, textiles and soft goods, and they are lighter than a cardboard box, which helps keep postage costs down.
Choose small mailing bags for accessories and single items, medium postage bags for tops and jeans, or large and extra large grey mailing bags for coats, bedding and bulk orders. Buy a pack of 100 or save with bulk packs of 500, 1,000 or more.
