Mail order

We're moving ever closer to a totally online world, and online shoppers are looking for a fantastic shopping experience. Your parcel packaging is the first line of this experience.


Secondary to the external transit packaging, the bespoke box gives your clients added assurance of a beautifully packaged purchase, along with protection and peace of mind.


The high street is still the place to get your brand noticed. With 'carrier bag tax' an important factor, our expertise will guide you through the options available.

Don’t be dull - go branded!

We’ve been making mailing bags for over 20 years now. In the early days, the only option was the ‘bog standard’ plain grey mailing bag. It’s certainly stood the test of time, we’re sending more goods than ever out via e-commerce, and our standard grey mailers are still one of our best sellers.

Times move on, and Sun Packaging now offers a truly bespoke, professional design service, from initial idea through to completed product delivery.

Why go for bog standard? We can supply any colour, printed with your design (we can also design from scratch too!), starting at just 500 bags! We will also advise on protective accessories where required, and the most eco-friendly options available.

We’re now a leading supplier of some of the most striking and best quality strong bespoke mailing bags, across all types of e-commerce. Clients are turning to us for our 40+ years expertise in the industry, where we can offer ideas on design and specification, resulting in a cost effective and positive customer delivery experience.

We believe that your clients’ purchase and delivery experience is enhanced upon the delivery of their order. The receipt of goods not only requires a timely delivery, but one of striking professional design and protected transit packaging. This is where we can help. Look at some of our previous work below, and contact us for further information and samples.

Green Polythene - 100% Sustainable

What is Sugar Cane Polymer?

Sugar cane polymer is a totally renewable, totally recyclable material, now available for manufacture into many types of polythene packaging.

Sugar cane plant is grown around the world for commercial use. During the processing and refining of this, ethanol is extracted. This ethanol is used to create a sugar cane based pellet that has captured 2.5kg of co2 for every 1kg of pellet produced. Taking into account transportation and manufacture of plastic products, GreenPolythene is a carbon neutral product.

More Information

It's become increasingly clear that biodegradable plastic is not the eco-friendly solution to reduce our plastic pollution problem around the world. Not only can biodegradable plastic not be recycled (in a re-processing plant); when it degrades, it breaks into tiny pieces which, if it finds its way into the oceans, seriously affects marine life.

Ethically, polythene producers now turn to a viable alternative polythene product that's not only environmentally friendly, but also suitable for the recycling mix and for subsequent reuse. Certain products require polythene due to the nature of the protection required, rather than labour intensive paper and card. The answer is GreenPolythene. 

Sugar cane processing results in a waste by product, of which ethanol is used to create a polymer that’s bio-based rather than oil-based (such as crude oil based polythene). During the growth of the sugar cane, the natural process of photosynthesis sees carbon captured. Initially, this raw material is carbon negative. As sugar cane is obviously a plant, it's totally renewable and won't deplete fossil fuels (such as crude oil, used for standard polythene), which is of enormous environmental benefit.

The production process inevitably generates carbon through factors such as manufacturing and transport, which means that by the time the bio-based polythene is produced it is actually carbon neutral. The Carbon Trust recently accredited an example of sugar cane based polythene bags as carbon neutral, confirming that it’s possible to nullify the effect of carbon emissions.

It’s worth considering some additional key points. The UK uses some 1 million tonnes of polythene films and bags every year. Using fossil fuel polymers to meet this demand costs the planet 2.6 billion tonnes of CO2 annually. By widely implementing GreenPolythene this figure could be drastically reduced.
