Mailing Bags

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.

The KB Packaging range of Grey mailers are our best value mailing sacks, available in a wide range of sizes to meet your needs. The 55-micron thick grey material provides high strength while remaining very lightweight to minimise postal costs. The Black inner film makes these bags opaque increasing security while in the courier networks.

The 40mm lip includes a permanent adhesive peel-&-seal strip. This feature eliminates the need for tape, simplifying the whole packing process for increased efficiency and ease. These features combined together make this product the perfect eCommerce postal bag.

The grey/black polythene is made from 100% recycled materials, making it a low-cost and environmentally friendly option and reducing your carbon footprint.

In addition to the range held in stock there are a number of sizes available. These are on a 5-7 day lead time depending on what day you place your order.
