Mailing BagsOur mailing bags are a very popular product within the postal packaging industry, an ideal choice for mail order and retail, being durable and waterproof. Common uses being to protect clothing, books, magazines and textile items when shipping (i.e. moisture resistance). Also to keep loose items together i.e shoes or multi product orders. Our grey mailing bags are made from 45, 50 or 55 micron polythene and our white 60 microns and both come in 10 different sizes. All have a peel and seal adhesive strip for easy closure meaning that no tape is required.
