Why choose double walled cardboard packing boxes?

Double walled cardboard is comprised of a dual layer of corrugated material and is designed to provide twice as much strength and protection as a single walled box. The layers are securely glued together to offer increased resistance against compression forces that are unavoidable when shipping or transporting items. The advanced construction guards against damage so that your parcels arrive in the best condition possible.

What varieties are available?

We offer a diverse range of sizes to cater toward most industries and items that need to be dependably packaged. Our 0201 double walled cardboard packing boxes are one of the most popular types of cardboard cartons for shipping goods via a carrier or postal network. As such, we supply an extensive variety of sizes to satisfy the needs of most businesses.

What are double wall packing boxes used for?

There are near limitless uses for cardboard boxes and the second corrugated layer increases versatility further. The additional strength is well suited to heavier objects that might put a strain on our single walled cartons in addition to companies posting large orders of multiple items. Postal services can safely stack these boxes without crushing any surrounding parcels and the extra protection granted by the double corrugated layers is also ideal for shipping sensitive products. However, if you would deem your products to be extremely heavy, don’t hesitate to get in touch with our professional team of product experts who are able to recommend a more suitable packaging solution, such as our export and pallet boxes which are designed specifically to accommodate larger projects.

How much weight can a double walled box hold? 

Small to medium-sized double wall boxes have a loading capacity of 18-36kg depending on the size of the box, while the larger sizes can hold between 27-54kg of evenly distributed weight. 

When packing items, it is advisable to distribute the weight of items evenly to prevent any one area if the box being strained. If you are shipping particularly heavy items, you may want to consider reinforcing the box with additional packaging materials, such as our foam protection products, or opting for a stronger box like our extra heavy-duty boxes. 

How much does a double wall cardboard box weigh? 

The weight of a double wall cardboard box can vary depending on several factors, including its size, dimensions, and the thickness of cardboard used in construction. Our smallest size of double wall box weighs 0.0985kg, going up to 3.2kg for the largest size. To view the unit weight of your chosen box, select the ‘more info’ icon in the product table. 

Please note, you will need to account for both the weight of the box and its contents when calculating shipping costs.

These are suitable for slightly heavier goods. Double wall boxes have 2 layers of corrugated board, making them our strongest general-use boxes.

Extra heavy duty boxes are manufactured from extremely strong cardboard and are suitable for very weighty goods.

Video: How to measure a product
A demonstration on how to measure your product correctly, and choose the right box.

Step 1:
How big is your product? Standard box dimensions are given in the order length x width x height. Measure the length with a tape measure. Next, measure the width. Measure the height/depth.

Step 2:
Select a box that is slightly larger in all 3 dimensions. This will allow for extra padding to protect your product. You will need the INTERNAL dimensions of the box. Depending on the board grade, this could be up to 10mm less than the external dimensions. To check that your box is the correct size, measure the length, width and height on the INSIDE of the box. All dimensions provided for our boxes are internal.

Step 3:
Wrap your product in a suitable padding material and place inside the box. It should be a snug fit to prevent movement.

Step 4:
Close the box and seal with tape or strapping as required. Consider our custom logo printed tape for a cost-effective branded sealing option.
