Description

Heavy Duty Mailing Box: 270 x 270 x 175mm

This robust Double Wall Heavy Duty Mailing Box, model B950, offers superior protection for shipping and storage. Its sturdy construction ensures your items remain secure during transit, making it an ideal choice for e-commerce businesses and individuals alike.

  • 270 x 270 x 175 mm dimensions provide ample space for a wide range of products.
  • Double wall construction delivers exceptional strength and puncture resistance.
  • Expertly made in Australia, ensuring high-quality manufacturing standards.
  • Features the distinct B950 code for easy identification and reordering.

Engineered with double wall corrugated board, this box significantly surpasses the protection offered by standard single-wall mailing boxes. Its reinforced structure is built to withstand the rigors of shipping, safeguarding contents against crushing and impact far more effectively than typical alternatives.

Questions about this box

Is the size inside or outside the box?

All sizes are internal (length x width x height), measured inside the box. The outside is a few millimetres bigger because of the board thickness.

What does the pack size mean?

The pack size is how many boxes come in one pack, for example x25 is a pack of 25 boxes. "Number of packs" sets how many packs you get, so x25 with 2 packs is 50 boxes.

Are the boxes delivered flat?

Yes. Regular cartons are delivered flat to save space and fold into shape in seconds.

How do I seal the box?

Use 48mm packaging tape along the top and bottom seams. For heavy items, also tape across both ends. See "How to fold & seal" above.

Can I return the boxes?

Yes. We offer 90-day returns on unopened items. See our refund policy.
