Why choose a single wall cardboard box?

Single wall cardboard boxes

Comprised of a robust single layer of corrugated cardboard, these boxes deliver high-quality protection that’s more than sturdy enough to support many of our customers’ needs at Kite Packaging. With a whole host of uses, they’re ideal as storage or shipping boxes and especially effective as ecommerce boxes, offering reliable performance for businesses of all sizes.

Multiscore Single Wall Cardboard Boxes

Select single wall cartons come multiscored, allowing you to reduce the height by cutting down the corners and folding to the marked depth - giving you adjustable sizing in one box.

Simple to Assemble

Supplied flat-packed for easy storage, these single walled cardboard boxes are quick to assemble using any standard packing tape and dispenser.

Easy to Seal

Secure the top and bottom flaps easily for a strong, stable finish - ideal for everyday packing as well as shipping items.

Compare single wall, double wall, Enviro boxes and extra heavy duty boxes. Discover which is best for your product.

We sell various types of boxes, from standard duty single wall to extra heavy duty.

Single wall boxes are identified by the prefix ‘CSW’.

Heavy duty Enviro-boxes have a clear ‘Enviro’ print on one of the flaps.

Double wall boxes have a code starting ‘CDW’.

Extra heavy duty boxes are labelled XHD on one of the flaps

Our single wall boxes have a single layer of corrugated board. They are our best value option for packing lightweight goods. Enviro-boxes are made from a thicker and more rigid single wall board. 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.

Learn how to adjust the height of multiscore boxes using one of our safety cutters

Watch a demonstration video on how to adjust the height of multiscore boxes using one of our safety cutters.

Many of our cardboard boxes have multiscore lines that allow the height to be adjusted.

We sell a box cutter that enables this to be done quickly and safely, due to its retractable blade.

Multiscore lines are clearly visible, look at the table on the box page for their height.

Using the knife, cut down each corner to the height you require.

Insert your items, then fold down the flaps to the new height.

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 cheap branded sealing option.

FAQs

How Thick is Single Wall Cardboard?

Single wall cardboard is 2.3 - 3mm thick, depending on whether it has R or B fluting.

What is the Weight Limit for a Single Wall Cardboard Box?

Small to medium-sized single wall cardboard boxes are intended for small to medium-sized items, generally holding between 13-18kg of evenly distributed weight.

Large single wall boxes are still best for light to medium-weight items, but they can support a load capacity of up to 23-32kg if evenly distributed.

For heavy or fragile goods, we recommend double wall or heavy-duty boxes. Need a better fit? Explore our custom-sized boxes.
