Our white coex mailing bags are completely opaque. White and glossy on the outside and black on the inside, they are co extruded for extra security. The co-extrusion process fuses two layers of film together to made a high quality bag, providing a reliably opaque finish. They are waterproof and 100% recyclable.
These postal bags are made from 50 micron polythene and are a medium duty strength. Suitable for clothing, textiles, gifts, and books.
They have a strong tack self adhesive flap which provides a permanent seal, and can either be addressed with a label or written on with a marker pen.
