Why choose a single wall cardboard box?

Single wall cardboard boxes

Comprised of a single layer of corrugated cardboard, these single wall cardboard boxes provide high-quality protection that is more than sturdy enough to support many of our customers’ needs. We provide this standard construction at a very affordable wholesale price, making this product one of our most popular products.

What physical qualities do single wall cardboard boxes have?

Our general-purpose corrugated cartons are made of a durable four-flap design that arrives flat-packed for convenient storage. To create the box, use one of our many packing tapes to secure the bottom and top flaps, incorporating one of our tape dispensers for ease. All of our single wall cartons are a standard brown colour on both the inside and outside. Some of these boxes have the added advantage of being multiscored. This allows you to reduce the depth of your carton to a pre-scored dimension, by cutting down the existing slots (between the flaps) and folding along the pre-scored crease. Multiscore depths, where applicable, are marked in the table and are always located inside the box. Furthermore, it is worth noting that some of the flaps are printed with our logo, a barcode and the size reference. 

The sizes shown in the product table are the internal dimensions of the single wall box once constructed, and in the order of: length x width x height.

How thick is a single wall box? 

A single wall box features a single layer of fluting sandwiched between two flat linerboards, and the thickness of this can vary between specific board grades and manufacturers. Our single wall boxes have R and B fluting, giving these board grades a respective thickness of 2.3mm and 3mm. In ‘Products’, click the ‘more info’ button which tells you the exact fluting and board thickness of each size of single wall cardboard box we stock. 

What is the weight limit of a single wall cardboard box? 

The weight limit of single wall boxes can vary depending on a few factors, including size and dimensions of a box, the quality of the cardboard material, and how the weight is distributed within the 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, however they may be able to support 23-32kg of evenly distributed weight. 

Heavy and fragile items require extra protection so you may want to consider using our double wall, extra heavy-duty, or enviro boxes to ensure the weight of your items is safely supported.

Are they environmentally friendly?

Our cardboard boxes are made from recycled materials, the percentage of which ranges from 60% to 90% and this cardboard is one of the most easily recycled resources in the UK. Seal with one of our paper tapes and fill with environmental void fill for the perfect plastic-free packaging. These single walled boxes are kind to the planet and vegan friendly. 

What are corrugated boxes used for?

Our vast range of different sizes makes these boxes suitable for professional or domestic use. An extremely versatile item, these cardboard cartons can dependably package items ready for shipping or provide a long-lasting storage solution in either a warehouse or your own home. 

The universality and versatility of a cardboard box equips it for an array of varied applications across industries.

Video: What type of box do I need?

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.
