Manufactured from 100% recycled material, our high quality grey polythene mailing bags are a very popular, light-weight, cost-effective source of packaging for the mailing of non-fragile goods. Available in various sizes, our mailing bags all adhere to the Royal Mail PIP guidelines, enabling an accurate estimation of possible postage costs, which are also potentially reduced with the use of this light-weight packaging. Smaller bags are best suited to send lighter items such as literature, textiles, clothes etc., with larger bags predominantly being used for heavier, bulkier or boxed items, or when a “courier despatch sack” is required. All variations of mailing bag have a secure peel and seal strip, with a 40mm lip and, as they are opaque, are also ideal for the mailing of confidential and private literature.
