Printed Postal Boxes for Every Shipping Need

When it comes to shipping your products safely and stylishly, the right packaging makes all the difference. At Pixartprinting, our range of custom mailing boxes combines robust protection with outstanding print quality — so your brand makes an impression from the moment your parcel arrives. Made from corrugated board with a fluted structure that insulates and cushions the contents, our shipping boxes are built to keep your products safe in transit, whatever the journey.

Available in a wide variety of styles and sizes, our custom postal boxes can be printed on both the inside and outside, giving your customers a memorable unboxing experience that reflects the quality of your brand. The majority of our packaging products are FSC® certified, so you can ship with confidence knowing your packaging is responsibly sourced.

Custom Mailing Boxes in the UK

The UK e-commerce market is more competitive than ever, and packaging has become a key touchpoint in the customer journey. A well-designed, custom-printed shipping box doesn't just protect your product — it tells your brand's story before the customer has even opened the parcel. At Pixartprinting, we make it easy for UK businesses of all sizes to create professional, fully branded mailing boxes that stand out at every stage of the delivery process.

Our corrugated board postal boxes are available in a range of styles to suit different products, shipping requirements and budgets. Whether you need slim flat postal boxes for documents and prints, robust packing boxes for heavier goods, or premium postal boxes for a luxury unboxing experience, we have a solution to match.

Custom Shipping Boxes for Small Businesses and Growing Brands

Our short print runs mean you can order exactly the quantity you need, without committing to large minimum orders that tie up your budget. Custom mailer boxes with your logo, brand colours and messaging are an affordable and impactful way to elevate your customer experience and build brand recognition with every single shipment.

Sending wine, spirits or other bottled products? Our cardboard wine carriers are specifically designed to keep bottles secure and protected in transit. Fully customisable with your branding, they double as a stylish gift carrier — ideal for wineries, distilleries, hamper companies and corporate gifting.

Heavy-Duty Shipping Boxes: The Strength of Corrugated Cardboard

All of our mailing boxes are manufactured from high-quality corrugated cardboard, chosen for its exceptional strength-to-weight ratio and protective properties. The fluted inner layer acts as a natural shock absorber, cushioning your products against impact and vibration during transit. Whether you're shipping fragile items, heavy goods or irregularly shaped products, corrugated board provides the reliable protection your shipments need — without adding unnecessary weight or bulk to your parcels.

Custom Size Postal Boxes

Standard sizes don't always suit every product, which is why we offer custom size options across our mailing box range. Simply select your required dimensions when configuring your order, and we'll produce postal boxes that are a perfect fit for your products. A correctly sized box not only looks more professional — it also reduces the need for excess void fill, saving you money on materials and keeping your packaging more sustainable.

Shipping Boxes with Your Logo

Your packaging is often the first physical interaction a customer has with your brand, so make it count. Our custom printed shipping boxes can be personalised with your logo, brand colours, patterns, messaging and more — both inside and outside the box. A beautifully branded unboxing experience encourages customers to share their delivery on social media, generating organic brand awareness and helping to build the loyalty that keeps them coming back.
