Standard mailing bags

Cost-effective mailing bags are ideal for a range of businesses, and in many cases reduce shipping costs when compared to boxes.

Made from recycled materials but without compromising on quality, they are popular with a wide range of industries including mailing, catalogue and e-commerce businesses.

All sizes of our grey mailing bags adhere to Royal Mail's PiP guidelines, so you can accurately calculate your postage costs. Smaller sizes are great for sending clothes, literature and textiles. Larger sizes are typically used when a courier despatch sack is required (for bulky or boxed items).

Please be aware the shade of grey may vary from images due to recycled content.
