Long Postal Boxes

Our Long Postal Boxes (also known as long shipping boxes or extended-length mailers) are specially designed for UK businesses to provide secure, efficient protection for elongated or narrow items during postal, courier, or e-commerce shipping—ensuring contents arrive undamaged and presented professionally every time.

Made from high-quality single-wall corrugated cardboard, these boxes deliver excellent resistance to bending, crushing, and impacts along their extended length—essential for items that could flex, warp, or break in transit.

Key features and benefits include:

• Robust and protective design — Constructed from durable corrugated board, they absorb shocks from rough handling, automated sorting, conveyor belts, and multi-drop courier journeys, keeping long items safe and secure.
• Optimised for elongated products — Available in extended lengths, they perfectly suit items that won't fit standard square or cubic boxes, avoiding awkward folding or the limitations of rigid tubes.
• Versatile applications — Ideal for a broad range of long, narrow, or cylindrical goods popular in UK e-commerce and retail, such as posters and prints, blueprints, artwork, rolled canvases, fishing rods, golf clubs, curtain rods and poles, fluorescent tubes or LED strips, architectural models, trim pieces and mouldings, banners and signage, yoga mats, telescopes, slim gift sets, or even certain flat-pack elements—offering superior flat protection and cushioning compared to mailing tubes.
• Lightweight and cost-effective — The single-wall build minimises added shipping weight, helping to reduce postage fees, dimensional weight charges, and carrier costs—making them a smart, economical choice over heavier tubes or oversized standard boxes, especially for high-volume shippers.
• Easy assembly and secure closure — Supplied flat-packed and pre-scored for fast, intuitive setup (with auto-bottom or crash-lock bases available on select models); generous flaps allow secure taping, tuck-in ends, or optional peel-and-seal adhesive strips—streamlining packing in fulfilment centres, 3PL operations, or home-based setups.
• Professional appearance — Offered in clean kraft brown for a polished, brand-friendly look. Smooth surfaces support excellent label adhesion, direct printing, or custom branding (logos, messaging, or thank-you notes), elevating the unboxing experience and reinforcing your online brand identity.
• Sustainable and recyclable — Produced from responsibly sourced, fully recyclable corrugated materials (often with high post-consumer recycled content), aligning with UK eco-friendly practices and sustainability goals without sacrificing strength or reliability.

Additional advantages:

• Carrier compatibility — Engineered to fit within dimensional limits of major UK carriers, such as Royal Mail/Parcelforce (up to 2.5m length for large parcels via Parcelforce services, with length + girth combined up to 4m in some cases), Evri (max length 120cm, length + girth 245cm), DPD, UPS, Yodel, and DHL—helping avoid surcharges or rejections for oversized items.
• Storage efficiency — Flat-packed delivery and easy stacking save valuable warehouse or stockroom space.
• Customisation options — Many ranges include bespoke sizes, specific flute profiles, or printed designs to meet branded or precise requirements.

Choose our long postal boxes for dependable, space-efficient packaging that safeguards elongated products, cuts shipping expenses, and creates a professional impression—ensuring your UK shipments arrive safely, impress customers, and support repeat business every time.
