A super tough, opaque mailing bag with a permanent self-seal adhesive strip. These mailing bags are ideal for mail-order items such as garments, soft goods and boxed products. Polythene mailing bags are also puncture-resistant and waterproof.
The grey mailers are thicker than some brands in the market. Our mailing bags are manufactured from a co-extruded film that is black on the inside and grey on the outside. The grey mailer co-extruded film is made from 100% recycled plastic and can be recycled. The grey mailers are also available without the printed safety notice by request.
Alternatively, if you’re looking for a custom printed mailing bag with your company logo and details in a bespoke colour please contact KB Packaging on 0115 944 1600.
