When it comes to moving home or storing valuable items, our double wall cardboard boxes offer unmatched strength and reliability. Crafted from two layers of corrugated cardboard, plus reinforced fold-over flaps on the base and lid, these boxes are designed to provide double the protection you’d get from standard single-wall alternatives.

What Makes Double Wall Boxes So Strong?

Each double wall box features dual corrugated layers, which absorb shocks and resist crushing under pressure. The fold-over flaps add another layer of thickness at the top and bottom seams—areas that often fail on lesser-quality boxes. These features combine to deliver boxes that are robust enough for heavy books, fragile ornaments, electronics, and long-term storage without risk of collapse or damage.

Unlike many single-wall options, our double wall boxes maintain their shape even when stacked, helping your belongings stay safe whether in transit or in storage.

Benefits for Moving Home & Self-Storage

For anyone planning a move—or storing items in a loft, garage, or storage facility—double wall boxes are the safest bet. They’re specifically designed to handle the stresses of moving vans and busy storage environments. By resisting tears and structural failure, they reduce the risk of crushed or broken items.

Reusable and recyclable, our boxes offer eco-friendly durability. Once you’re done, simply dismantle, flatten, and recycle—or reuse them for future storage or moves.

Choosing the Right Size & Shape

We offer a full range of sizes to suit every room in your home—from small double wall boxes for glassware and jewellery, to large ones suitable for bedding, toys, or sports gear. Staying within a good lifting width (around 18″/457 mm) ensures that you avoid awkward, unwieldy loads. This shoulder-width approach reduces the risk of injury and fatigue.

If you're storing clothes, consider pairing your double wall boxes with garment or wardrobe boxes—also available in double insulated versions to keep contents tidy and crease-free.

Tips for Best Use

To get the most out of your double wall boxes, here are some user-tested tips:

  • Always reinforce the bottom with heavy-duty tape.
  • Fill gaps with paper or bubble wrap to prevent internal shifting.
  • Stack in alternating directions to create a load-sharing “brick wall” and maximise strength.
  • Label boxes clearly with contents and destination room. Add “Fragile” tags where needed.
  • Reuse boxes over multiple moves or for seasonal storage—they hold up well over time.

Frequently Asked Questions

How much weight can a double wall box hold?

Typically between 25–30 kg, depending on the box size and brand. Always check individual box specs before use.

Are fold-over flaps better than regular lids?

Yes. The fold-over flaps create extra layers of cardboard at key stress points, reducing the risk of top or bottom cavities failing under pressure.

Can I use these boxes for long-term storage?

Absolutely. Our double wall cardboard boxes are designed for longevity, making them ideal for year-round storage in lofts, garages, or storage units.

Are they recyclable or reusable?

Yes, they’re both. Once you’ve finished using them, simply dismantle and recycle. If still in good condition, keep them for future moving or storage needs.

Is there a big price difference from single-wall boxes?

Double wall boxes cost more upfront but can save you money by preventing damage to your items and offering long-term value. For delicate or heavy loads, the investment is well worth it.
