Strong, extra heavy duty boxes

Our strongest, sturdiest corrugated boxes are designed for heavy goods and providing maximum protection. When shipping or transporting heavy goods, items prone to damage in the supply chain or goods with a high value, it is vital that strong, reliable and robust outer protection is used. We have a wide range of sizes suitable for engineering equipment, automotive parts, electronics equipment, machined parts, hydraulic components and much, much more. Given the high value of the goods shipped using this type of cardboard box our customers need peace of mind that our extra heavy duty cardboard boxes will more than deliver on the promise of providing the right protection.

Extra heavy duty cardboard boxes from Kite Packaging are manufactured to a high technical degree and have been added to our range following in-depth research and development. They have also been subjected to rigorous testing to ensure they are fit for the purpose of looking after your valuable or heavy items.

Popular with companies exporting goods aboard, our new heavy duty cartons are now a more popular choice for customers who previously favoured triple wall corrugated cartons as their method of packing. Made from heavy weight board and with strong fluting combinations, these extra heavy duty boxes are more cost effective than triple wall cartons.

Rigorous testing procedures

For many customers purchasing these cartons it is vital to understand the specifics of their technical make up and performance. The product table above summarises the key technical specifications and by clicking on the ‘More info’ tab you can access even more in-depth and relevant facts. These include important metrics about how these boxes perform:-

  • Maximum load:
    This is the maximum weight that the box can support without the sides buckling.
  • Edge Crush Test (ECT):
    This measures the top to bottom compression strength of the board. It gives information on the ability of a particular board construction to resist crushing. A laboratory test method is carried out that measures the cross-directional crushing of a sample of corrugated board.
  • Box Compression Test (BCT):
    This measures the compression resistance, shape change and stacking capability of the carton. The BCT of a corrugated box is the maximum force sustained by the box during compression, and is an indication of the stacking resistance of the box during storage and transport.

On each related ‘More info’ table you will also find both the internal and external measurements of the boxes. The external dimensions for this type of box, with its typical applications, are vital for anyone using them to export out of the country. This is because the exact space the filled box will occupy is a key element for calculating the cost of export and is a key measurable for shipping companies.
