Versatile flat pack boxes

Flat pack boxes offer a practical and space-efficient solution for a wide variety of packaging needs. Supplied flat, they minimise storage requirements before assembly, making them ideal for businesses with limited warehouse space. This design is perfect for e-commerce brands, subscription services, and retailers shipping items like clothing, books, prints, and electronics. The assembly process is straightforward, allowing for quick packing workflows. Our range covers numerous styles, from simple mailers to more complex product boxes. For example, a Custom Snap Lock Product Box provides a secure closure and a premium feel for retail items. We supply these boxes from Europe with a low minimum order quantity of just 30 units, making them accessible for businesses of all sizes. They serve a dual purpose of protecting goods during transit and presenting them professionally upon arrival.

Durable flat pack cardboard boxes

The structural integrity of our flat pack cardboard boxes comes from high-quality materials. The range consists of three-layer corrugated cardboard, available in E-flute and B-flute profiles for cushioning and rigidity. For retail presentation, we also offer options made from solid board. The testliner weights for our cardboard range from 380 to 460 gsm, ensuring a robust construction suitable for various product weights. All boxes are engineered with a dimensional tolerance of plus or minus 2-4 mm, ensuring consistency across your order.

Custom flat box packaging

Personalisation transforms a standard container into a branded asset. We offer extensive options for creating custom flat box packaging that reflects your brand identity. Using CMYK digital printing, we apply full-colour designs, logos, and text to both the outside and inside of the box. This allows for a complete branding experience, from the exterior shipping label to the internal unboxing moment. You can choose from several base colours, including brown kraft, plain white, or a white exterior with a brown kraft interior. To add a premium touch, our Custom Shipping Box can be enhanced with special finishes like hot foil stamping and protective varnish to highlight design elements.

Sizing for flat packing boxes

Our flat packing boxes align with standard shipping formats, including sizes configured for Royal Mail's parcel categories to help manage postage costs. They are also compatible with major courier networks. While we offer many stock dimensions, custom sizes are available to create a perfect fit for any product.

Practical flat boxes for posting

The slim profile of these containers makes them highly practical flat boxes for posting a wide range of items. They are an excellent choice for sending documents, photographs, art prints, and textiles. Small electronics, accessories, and promotional materials like a Custom Business Card also travel securely in this type of packaging. The flat design ensures the contents remain secure and unbent during transit, providing protection without adding unnecessary bulk or weight to the shipment.

Cardboard flat pack boxes for every product

Our collection of cardboard flat pack boxes includes solutions for nearly any application, from simple postal mailers to sophisticated retail containers. For straightforward e-commerce shipping, the Plain Flat Shipping Box is a durable and efficient option. The versatility of the format means it can be adapted for software, books, or clothing. For items that require a more substantial or luxurious presentation, consider exploring our range of rigid boxes, which offer a different construction style for premium goods. For a premium alternative, our custom rigid boxes offer a firmer structure.
