Reliable Postal Boxes for Shipping, Moving and Storage

When you need to send items, move house or store goods safely, using the right box matters. At Storage & Removal Boxes we provide a wide selection of postal boxes built for strength, convenience and performance - whether you’re dispatching parcels or packing up for a move.

What Are Postal Boxes?

Postal boxes are corrugated cardboard cartons specifically designed for mailing, courier dispatch and parcel storage. They are flat-pack delivered, easy to assemble, and made to offer protection during transport. According to UK packaging specialists, the best postal box options include large-letter formats, small parcel sizes and reinforced board to meet real-world demands.

Why They Matter for Home Movers and Online Sellers

Whether you’re relocating, clearing out storage or running an online shop, postal boxes give you essential benefits:

  • Safe transit: Corrugated board absorbs shocks and prevents crushing during shipping or moving vans.
  • Space efficiency: Flat-packed delivery allows you to store dozens of boxes without using lots of room.
  • Scalable sizes: With a wide range of sizes, you can choose the right box for books, clothes, electronics or full-house loads.
  • Eco friendly options: Many postal boxes are fully recyclable and made from sustainably sourced materials.

Our Postal Box Features

At Storage & Removal Boxes we’ve chosen postal boxes on criteria that matter to our customers:

  • Strong corrugated cardboard construction with well-defined flutes (waves) between layers, giving stability and protection. 
  • Flat-packed delivery so you save warehouse or garage space until needed.
  • A wide selection of sizes, including large letter compliant, small parcel, deep box styles and heavy duty options.
  • Easy assembly with locking tabs, peel-and-seal strips or standard flaps so you can pack quickly. 
  • Eco-conscious build: many boxes are fully recyclable and made with responsibly-sourced paperboard.

How to Choose the Right Postal Box

Use these straightforward steps:

  • Measure your item: Length + width + depth - make sure the box fits with extra space for padding if needed.
  • Consider shipping method: If using Royal Mail large letter or small parcel formats, choose a box size that meets those rules to save cost. 
  • Choose strength: For heavier items or moving house, opt for double wall or heavy duty fluting rather than standard single wall.
  • Think about storage: If you’ll store rather than ship, choose a flat-pack box with lid and sturdy build for stacking.
  • Eco goals: If sustainability is important, choose boxes labelled recyclable or recycled content and avoid plastic inserts if possible.

Expert Tips for Best Packing Practice

These simple tips help you get the best out of your postal boxes:

  • Use strong tape (minimum 48 mm width) on all seams before drop-off or dispatch.
  • Ensure items inside cannot move - fill voids with packing paper, bubble wrap or foam corners.
  • Label clearly - mark “Fragile” or “Do Not Bend” if the contents require extra care.
  • Stack wisely - when storing boxes, put heavier boxes at the bottom, lighter on top, and keep off damp floors.

Whether you’re shipping a parcel from Manchester, packing up for a move in Birmingham, or storing goods in self-storage in London, the right postal box makes everything easier. Choose the right size, pack with care and trust Storage & Removal Boxes to deliver across the UK.
