Benefits of Branded Mailing Bags:

Material options – The material you select for your packaging can have a significant positive impact on your environmental strategy. Recycled material has a much lower carbon footprint compared to conventional oil-based polythene. Plus, you’re re-using polythene waste. GreenPE, a bio-based material is from a renewable source, sugarcane, supported by an LCA, this material has a negative carbon footprint. Lastly, Oceanix HDPE, a recycled plastic made from waste fishing gear recovered from the ocean.

For every purchase of a GreenPE and/or recycled content packaging product, we gift a tree to plant locally and we make a donation to Greater Manchester City of Trees initiative. This is all part of our pact for the planet, find out more on our sustainability page.

Recyclable – Polythene branded mailing bags can be recycled in a closed loop recycling system. Many of Duo’s clients are helping to #bringwastefullcircle and close the loop on their post-consumer packaging waste by choosing our sister company Duclo Recycling based in Leeds, UK. Waste is collected upon delivering new packaging items, recycled at Duclo Recycling and the recycled pellets are used to make new packaging products. This systems helps to ensure that post-consumer mailing bags do not go to waste and are processed into recycled material to be used to make new products and help reduce reliance on virgin materials.  

Light-weight and cost effective – Polythene mailing bags are a cost effective solution for distributing parcels in the postal system due to their lightweight and flexible properties which help minimise size for volumetric shipping. Plus, they are compact meaning a large amount of bags can be stored on a single pallet, taking up less storage space compared to other packing materials such as cardboard boxes. Learn how we did exactly this for our client Charles Tyrwhitt, who used to receive 5 deliveries a week of cardboard boxes to now just 1 delivery a week of the same quantity of branded mailing bags.
