Our lightweight and 100% opaque White Heavy Duty Mailing Bags offer fantastic protection to a variety of heavier and/or shaper items during transit. Manufactured from tougher and more durable polythene, these heavy duty mailing bags are tear resistant. These 400mm x 500mm mailing bags are also co-extruded, which means several layers of film are extruded together for even securer protection.
These White Heavy Duty Mailing Bags - 400mm x 500mm - also adhere to Royal Mail’s PiP guidelines, so you can accurately calculate your postage costs.
Please note: these bags may or may not be printed with suffocation warning.
Please note: we have updated the print on these bags. You may receive a different print to the images.
