What is a standard mailing bag?

Our standard polythene bags are our best value mailing sacks, available in a large selection of sizes to suit a variety of products and purposes. The 55 micron thick grey material grants a reasonable degree of strength while remaining very lightweight to minimise postal costs. Your postage and packing outgoings can be accurately calculated thanks to the sizing table which corresponds with Royal Mail’s PiP guidelines. 

Intuitive practicality is embedded into the design with the 40mm lip that includes a peel-&-seal strip. This feature eliminates the need for tape, simplifying the whole packing process for increased efficiency and ease. These qualities are indispensable within a busy dispatch operation, promoting the fast functioning of an ecommerce business. Moreover, tape dispensers or cutting tools can be removed from a pack station, aiding organisation. To display delivery information, these standard mailing bags are commonly purchased with items from our comprehensive range of multi-purpose labels.

Are the polythene bags eco-friendly?

The grey polythene is made from recycled materials, making it a low-cost and environmentally friendly option. The extremely light weight further promotes the protection of our planet as it means that more parcels can be loaded onto a single vehicle, hence economising that space and reducing the overall carbon footprint of the process. It is worth noting that, as a result of the recycled content, the shade of grey may vary slightly from the images. 

Can you reuse a mailing bag?

These plastic mailing bags are made with a minimum amount of recycled material to suit their single-use purpose and hence, are not designed for reuse. However, there is nothing stopping a customer from reusing a grey mailing bag if it retains its high quality condition.

What are grey mailing bags used for?

Thanks to the wide range of sizes supplied by Kite, the standard postal pouches can carry a broad selection of products, making them suitable for various industries. The large letter sizes are perfect for sending out clothing, literature or textiles while the larger parcels are typically used for bulky or boxed items. The opaque exterior renders the envelopes suitable for sending out confidential materials too.

A polythene mailing sack is a great universal product with a variety of uses, making it an ideal versatile resource for companies sending out a range of different items. The flat-pack and ultra-thin arrival aids this end by conserving warehouse space.
