Packaging built
for high volume
supply
Our trade and bulk supply of printed mailing bags is designed for businesses requiring high-volume packaging solutions with consistent quality and reliable supply.
We work with wholesalers, fulfilment centres, ecommerce brands and distributors to supply large quantities of mailing bags, typically starting from 100,000 units and above.
Printed mailing bags provide a cost-effective and dependable packaging solution, ideal for businesses with ongoing shipping requirements. Whether you are supplying packaging to clients or fulfilling high order volumes internally, our bulk supply ensures you have the stock you need when required.
With a focus on quality, reliability and continuity of service, we help businesses streamline their packaging operations at scale.
We also offer options for custom specifications and finishes depending on your requirements.
This can include:
bespoke sizes and thicknesses
different material grades
colour options
optional branding or print runs for larger volumes
Our team will work closely with you to ensure your mailing bags meet the specific requirements of your operation, whether that’s for resale, fulfilment or internal use.
We know consistency matters for bulk supply, so we manufacture all products to the highest quality standards.
Our team will work with you to deliver high volumes of mailing bags, with minimum quantities typically starting from 100,000 units.
Ordering at this scale allows for a significantly reduced price per unit, making it an ideal solution for trade buyers, distributors and larger retail and ecommerce operations.
We can also support ongoing supply agreements, ensuring you have consistent access to stock without the need to place repeated orders.
For businesses requiring flexibility, we offer stockholding and a scheduled call-off delivery, allowing you to manage large volumes without the need for on-site storage.
Delivery timelines for trade and bulk mailing bag orders will depend on volume, specification and production requirements.
For standard specifications, lead times are typically 3–6 weeks, with shorter timelines possible for repeat or ongoing orders.
When purchasing in larger volumes, our stockholding and logistics management option allows you to call off stock as and when required, significantly reducing not just the need for storage, but also crucially reduced delivery times once your packaging has been produced.
We always work closely with our customers to ensure reliable and consistent supply, helping you avoid any delays or stock shortages.
We offer a range of options to support businesses looking to reduce the environmental impact of their packaging at scale.
Printed mailing bags can be produced using:
Recyclable materials
Recycled content (where required)
Specifications designed to reduce material usage
For high-volume orders, even small changes in material or design can make a significant impact on the overall packaging footprint.
We can advise on the best options to balance performance, cost, and sustainability across your packaging supply.

Returns are an unavoidable part of ecommerce. For many retailers, managing product returns efficiently is essential to maintaining customer satisfaction and operational efficiency.
The minimum order quantity for a printed polythene mailing bag is 500. Orders below this quantity cost the same amount to produce, so are not cost-effective.
For standard orders, we can achieve delivery within 7 days. For more complex orders, it can take up to 6 weeks to complete delivery.
Sizes depend on the base bag colour choice. Our comprehensive polythene mailing bag size guide gives you a full overview of the sizes available.
Standard bag colours are black and white, but you can create custom-coloured bags by flood printing them for orders over 3,000 bags.
Mailing bags are perfect for small or malleable items that can fit within a smaller frame. They mean businesses can sell products online without packaging and sending their products in boxes — an inefficient use of space and thusly costlier option. Printed mailing bags take your postage packaging from being efficient to effective, extending the perceived value of the purchase experience and delivering your brand to your customers' doors. A printed mailing bag turns your e-commerce product from 'generic' to 'branded'.
All of our polythene mailing bags are recyclable, and we're also committed to using recycled polythene in the materials of our bags. Currently, polythene is not recyclable at home in the UK, so you will need to encourage your customers to take waste mail bags to local recycling points. These are typically found at large supermarkets.
No, polythene mailing bags are not biodegradable.
Yes, polythene materials can be used for food products. We recommend always packaging your food products in BRC-accredited food-safe packaging prior to inserting in a printed mailing bag for delivery.
Yes, polythene mailing bags can be printed on either both or just one side. Specify your ideal print configuration in our bag builder.
